                                         RULING ON MOTIONS1

Vowell, Special Master:

        This ruling resolves all outstanding motions. It also provides a written rationale
for rulings issued summarily as this case proceeded to and through a causation hearing.
In summary, I deny: (1) a motion to compel a non-treating physician to testify or produce
documents; (2) a motion to apply judicial estoppel with regard to causation; (3) the
admission of an expert report from another Vaccine Act case; and (4) a motion to strike
the testimony of one of respondent’s witnesses. I also address two motions that are
now moot. I grant the motion to admit a number of medical journal articles filed long
after the evidentiary record closed, but only because they are largely cumulative and
engaging in the analysis necessary to exclude them would unnecessarily prolong the
resolution of this case.

1 [ * * * *This Ruling was originally issued on September 28, 2015. In this public Ruling, the family name of
the petitioners has been redacted pursuant to their request. In addition certain matter improperly filed by the
petitioners has also been redacted, upon the instructions of Special Master Vowell, from pp. 26, 27, and 32.
See Order filed on Dec. 2, 2015.]

                                                        1
                                            I. Procedural History.

        The convoluted procedural history of this case is set forth in some detail, as it
 places the resolution of the outstanding motions in context. It will be incorporated by
 reference in the causation decision that follows my ruling on these issues.

 A. The Initial Petition.

         On March 24, 2003, petitioners [ * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
* * * * * * ] filed a “Short-Form Petition for Vaccine Compensation” under the National
Childhood Vaccine Injury Act2 [“Vaccine Act”] on behalf of their son, A.K. Such petitions,
authorized by Autism General Order #1,3 alleged in a summarized fashion that the
vaccinee has a disorder on the autism spectrum. By filing a short form petition, they opted
into the Omnibus Autism Proceeding [“OAP”], and their case was stayed while discovery
regarding general causation issues was conducted.4

 B. The OAP.

        Beginning in 1997, but peaking numerically in 2002-03, thousands of petitions
 were filed alleging either that the measles, mumps, and rubella [“MMR”] vaccine or
 thimerosal, an ethyl mercury preservative used in multi-dose vials of many vaccines,
 caused ASD. The sheer volume of petitions filed—more than 1,300 new petitions in
 2002 alone—led to the creation of the OAP.5 Omnibus programs had been used
 2The National Vaccine Injury Compensation Program comprises Part 2 of the National Childhood
 Vaccine Injury Act of 1986, Pub. L. No. 99-660, 100 Stat. 3755, codified as amended, 42 U.S.C. §§
 300aa-10 et seq. (2012). Hereinafter, individual section references will be to 42 U.S.C. § 300aa of the
 Vaccine Act.
 3   By electing to file a Short-Form Autism Petition for Vaccine Compensation, petitioners alleged that:
           As a direct result of one or more vaccinations covered under the National Vaccine Injury
           Compensation Program, the vaccinee in question has developed a neurodevelopmental
           disorder, consisting of an Autism Spectrum Disorder or a similar disorder. This disorder
           was caused by a measles-mumps-rubella (MMR) vaccination; by the “thimerosal”
           ingredient in certain Diphtheria-Tetanus-Pertussis (DTP), Diphtheria-Tetanus-acellular
           Pertussis (DTaP), hepatitis B, and Hemophilus Influenza Type B (Hib) vaccinations; or by
           some combination of the two.
 Autism General Order #1, 2002 WL 31696785 (Fed. Cl. Spec. Mstr. July 3, 2002), Exhibit A, Master
 Autism Petition for Vaccine Compensation at 2 (found at 2002 WL 31696785, 2002 U.S. Claims LEXIS
 365, or http://www.uscfc.uscourts.gov/sites/default/files/autism/Autism+General+Order1.pdf) (last visited
 on July 27, 2015). In filing a short-form petition, petitioner joined the Omnibus Autism Program [“OAP”],
 explained in more detail, infra.
 4 See Autism General Order #1, 2002 WL 31696785, at *5-7 (indicating claims filed using the short form
 petition will be included in the OAP and automatically stayed while litigation on general causation issues is
 conducted); see also Notice, issued Apr. 9, 2003, at 1 (describing the OAP as “a general inquiry by the
 Office of Special Masters (“OSM”) regarding the possible causal relationship between certain vaccinations
 . . . and autistic spectrum disorders or similar neurodevelopmental disorders.”).
 5See Autism General Order #1. It is impossible to determine precisely how many petitions alleging
 vaccine causation of autism were filed in the OAP, as the nature of suit codes used to track Vaccine Act
 cases do not contain a code for autism or similar neurodevelopmental disorders. Estimates range from

                                                         2
previously in Vaccine Act cases to make causation determinations in groups of cases
alleging that a particular vaccine caused a specific injury, but the OAP was, by far, the
largest grouping of similar cases.6

        Following a series of meetings with an informal advisory committee (comprised of
petitioners’ counsel representing many of the Program claimants and legal and medical
representatives of the Secretary of Health and Human Services), the Office of Special
Masters [“OSM”] adopted a plan that would allow a period of discovery, followed by the
selection and litigation of test cases on the theories of causation presented. Autism
General Order #1 at 2-3. The conclusions reached on general causation and the
evidence adduced in the test cases would then be used to resolve the remaining claims.
Id. at 3. Those who had already filed petitions were allowed to “opt in” or “opt out” of the
proceedings, and future claimants could automatically “opt in” by filing the short form
petition included as Attachment B to Autism General Order #1. Id. at *6-8.

        Attorneys representing petitioners created the Petitioners’ Steering Committee
[“PSC”] to coordinate the OAP litigation. The PSC acknowledged that there was
insufficient evidence at the time the OAP was created to prove vaccine causation, but
averred that such evidence could be found through discovery and ongoing scientific
investigations. Petitioners sought and received an extended period of delay to conduct
discovery and prepare to litigate the test cases.

       Nearly five years after the OAP was created, litigation in the test cases began,
with the PSC presenting two different theories on the causation of ASD in two sets of
test cases. The first alleged that thimerosal-containing vaccines and the MMR vaccine,
in combination, could cause ASD (Theory 1). The second alleged that thimerosal-
containing vaccines could cause ASD (Theory 2). In accordance with the intent that
OAP test case evidence be made available to assist with the resolution of the remaining
OAP cases, the evidence (including expert reports, transcripts of testimony, trial
presentation materials and trial exhibits, and lists of the medical journals and other
documents filed by the parties) was posted on the Court of Federal Claims website.7

       Decisions in each of the three Theory 1 test cases, which were tried in 2007,
rejected petitioners’ causation theories. Cedillo v. Sec’y, HHS, No. 98-916V, 2009 WL
331968 (Fed. Cl. Spec. Mstr. Feb. 12, 2009), aff’d, 89 Fed. Cl. 158 (2009), aff’d, 617
F.3d 1328 (Fed. Cir. 2010); Hazlehurst v. Sec’y, HHS, No. 03-654V, 2009 WL 332306
(Fed. Cl. Spec. Mstr. Feb. 12, 2009), aff’d, 88 Fed. Cl. 473 (2009), aff’d, 604 F.3d 1343

5,400 to over 6,000 cases, with the latter number including cases filed after the initial test case hearing
dates were announced.
6See Hennessey v. Sec’y, HHS, No. 01-190V, 2009 WL 1709053 (Fed. Cl. Spec. Mstr. May 29, 2009),
aff’d, 91 Fed. Cl. 126 (2010) (discussing the different types of omnibus proceedings conducted in the
Vaccine Program).
7See http://www.uscfc.uscourts.gov/docket-omnibus-autism-proceeding (last visited on September 17,
2015). The parties in the test cases all filed explicit written consent to make these materials publicly
available. See, e.g., Mead v. Sec’y, HHS, No. 03-215V, 2010 WL 892248, at *1 n.1 (Fed. Cl. Spec. Mstr.
Mar. 12, 2010) (referencing petitioners’ and respondent’s written consent in that case).

                                                       3
(Fed. Cir. 2010); Snyder v. Sec’y, HHS, No. 01-162, 2009 WL 332044, aff’d, 88 Fed. Cl.
706 (2009).8

       Decisions in the three Theory 2 test cases, which were tried in 2008, also
rejected the causation theory presented. Petitioners did not seek review of the special
masters’ decisions. Dwyer v. Sec’y, HHS, No. 03-1202V, 2010 WL 892250 (Fed. Cl.
Spec. Mstr. Mar. 12, 2010); King v. Sec’y, HHS, No. 03-584V, 2010 WL 892296 (Fed.
Cl. Spec. Mstr. Mar. 12, 2010); Mead, 2010 WL 892248.

        An impressive body of medical and scientific evidence was adduced in the OAP
test cases, with the three special masters who heard this evidence finding that the issue
of vaccine causation was not a close call. See e.g., King, 2010 WL 892296, at *90;
Snyder, 2009 WL 332044, at *198. Each of the three special masters independently
determined that the medical theories advanced were not reliable and that the test case
petitioners had failed to produce preponderant evidence of causation. The OAP test
case litigation concluded in 2010, with the last Federal Circuit decision affirming the
dismissal of the final Theory 1 test case.9

C. Test Case for Theory 2 Litigation.

        This case was reassigned to me on December 18, 2007, when the autism docket,
handled from the beginning of the OAP by Special Master Hastings, was divided among
three special masters in anticipation of the test case hearings. In early 2008, the PSC
identified A.K.’s case as one of the three Theory 2 test cases. See Autism Update,
issued in the OAP docket on Jan. 17, 2008, at 2-3.10 Mr. Thomas Powers, a member of
the executive committee of the PSC, substituted as attorney of record, vice Steven
Tannenbaum. See PSC Roster, filed in the OAP docket on Mar. 9, 2007; Motion to
Substitute Attorney, filed Jan. 8, 2008 (granted the same day).

      Over the next three months, the PSC filed expert reports addressing general
causation under Theory 2 in the OAP docket and in the evidentiary record of this case.11
The expert report of Dr. Elizabeth Mumper was submitted in support of both general

9   Cedillo v. Sec’y, HHS, 617 F.3d 1328 (Fed. Cir. 2010).
10Throughout this ruling, I occasionally reference documents issued or filed in the OAP docket. Such
documents will be specifically identified as a part of the OAP docket. Absent such identification, all other
references are to documents appearing on the docket of this case.
11 Expert reports were filed in the OAP docket in late 2007 and early 2008 from Drs. Sander Greenland,
Richard Deth, and Vasken Aposhian. These same reports were filed in the evidentiary record in this case
in early 2008. See Petitioners’ Exhibits [“Pet. Exs.”] 22-24. Although these reports are part of the
evidentiary record in this case, only Dr. Deth’s has clear relevance to the causation theory ultimately
presented in this case. In essence, Dr. Deth’s opinion in the Theory 2 test cases was much the same as
his theory here. Many of the slides he used to illustrate his testimony in this case were virtually identical to
the slides he used to illustrate his test case testimony.

causation and causation in A.K.’s case.12

       Respondent also filed expert reports and curriculum vitae [“CVs”] from multiple
experts, some addressing ASD in general and others addressing general causation with
respect to Theory 2 in the evidentiary record of this case. See Respondent’s Exhibits
[“Res. Exs.”] G-KK (CVs and expert reports from 15 experts).13 Additionally, she filed
medical literature specifically focused on causation in this case. See Res. Exs. A-F.14

      During this same time period, petitioners also filed medical and educational
records. See, e.g., Pet. Exs. 2-21, 25-30.

D. Petitioners’ Motion to Withdraw as a Test Case and from the OAP.

        On April 10, 2008, approximately a month before Theory 2 test case hearings
were scheduled to begin on May 12, 2008, petitioners filed a motion to withdraw A.K.’s
case as a test case. Petitioners explained that they were not abandoning the theory
“that thimerosal-containing vaccines (TCVs) were a substantial contributing cause of
[A.K.’s] autistic symptoms” but wanted the opportunity “to develop and present evidence
of additional and alternative causative factors.” Motion, filed Apr. 10, 2008, at ¶ 1 (ECF
No. 40).15 Petitioners also asked to withdraw from the OAP “in order to proceed to an
individual hearing on compensation.” Id. at ¶ 2. Respondent did not object and, as
Autism General Order #1 indicated that any petitioner could ask to have his or her case
heard individually at any time, I granted petitioners’ motion. See Order, filed Apr. 15,
2008 (ECF No. 41); see also Autism General Order #1 at 8.

12Doctor Mumper’s expert report was filed in the evidentiary record of this case on January 22, 2008.
See Pet. Ex. 1. Although Dr. Mumper’s expert report was filed in the OAP docket on January 8, 2008, it
was subsequently withdrawn. At the digitally recorded status conference on Apr. 9, 2013, petitioners
indicated that they did not intend to rely on Dr. Mumper’s report and requested that I strike it. I orally
granted their request. See audio recording at 2:42-44.
13Although respondent later consented to the disclosure of the majority of these expert reports on the
court’s website (see Respondent’s Consent, filed in the OAP docket on Feb. 2, 2009), the expert reports
specific to this case were never filed in the OAP docket.
14 The medical literature filed during the period when this was one of the OAP test cases was not filed
directly into the OAP docket, but it was included on the parties’ “Master Lists.” These lists were created in
the Theory 2 test cases to avoid a problem that surfaced in the Theory 1 test cases. In the Theory 1
cases, multiple copies of the same medical journal article were filed and witnesses and counsel referred
to the same documents by different exhibit numbers, causing confusion. In the Theory 2 test cases, the
master lists were intended to comprise all of the medical literature filed by petitioners (Petitioners’ Master
List [“PML”]) and respondent (Respondent’s Master List [“RML”]). As new expert reports were filed that
referenced medical or scientific literature, that literature was added to and assigned exhibit numbers on
the master lists. See Order, issued Dec. 12, 2007 in the OAP docket, at 1. If an article appeared on
petitioner’s list, respondent was not required to include that article on her list, and vice versa. Id. at 1 n.1.
Respondent’s Exs. A-F in this case appeared as RML 32, 111, 325, 509 and PML 46, 93 on the OAP
docket’s master lists. The RML journal articles were filed into the record of this case via a CD containing
them. ECF No. 23.
15Because there are more than 300 docket entries in this case, some of which were filed on the same
dates, I will use the ECF docket number in most citations to identify the specific filing involved.

                                                        5
        When requesting that their case be withdrawn as a Theory 2 test case,
petitioners also requested that any case-specific material be withdrawn from the
publically-available OAP docket. Motion, filed Apr. 10, 2008, ¶ 3 (ECF No. 40). Thus,
Dr. Mumper’s expert report was withdrawn from the OAP docket, but remained in the
evidentiary record in this case until petitioners’ request to withdraw it prior to the
hearing. See January 8, 2008 Entry on OAP Docket (indicating it was no longer
appropriate to post the expert report containing case-specific information on the court’s
website after the case was withdrawn as a test case).

       Several months later (and after the test case hearings concluded), respondent
asked to withdraw the CVs and expert reports of two of her experts because she
determined their testimony would not be needed in the OAP Theory 2 cases.16
Respondent also requested that I remove them from the docket of this case. I granted
respondent’s request. See Order, issued July 29, 2008 (ECF No. 48). The CVs and
expert reports for the other thirteen experts remained in the evidentiary record for this
case.

        In a later-filed exhibit list, petitioners failed to include any of their OAP expert
reports. See Exhibit List, filed Apr. 13, 2013, at 1-2 (ECF No. 234) (listing Dr. Mumper’s
report as withdrawn and indicating “Not used for filing” for the exhibit numbers (22-24)
used to designate the other OAP expert reports). The only OAP report that they had
requested to strike was that of Dr. Mumper, and I had granted that request at the
digitally recorded status conference held on April 9, 2013 (see 2:43). The only other
expert reports withdrawn from the evidentiary record in this case with leave of court
were the two reports and CVs withdrawn by respondent in July 2008. Thus, the expert
reports for Drs. Deth, Greenland, and Aposhian remain part of the record of this case.

E. Proceeding as an Individual Case.

        1. Proceeding Without Retained Counsel.

       On May 22, 2008, [A.K.’s father] was substituted for Mr. Powers as the
attorney of record for his son.17 [A.K.’s father] represented that he entered an
16 Respondent sought to withdraw the CV and expert report of Dr. Thomas Clarkson (Res. Exs. L, Z) and
of Dr. Laszlo Magos (Res. Exs. K, Y). See Motion, filed July 8, 2008. Respondent withdrew these expert
reports from the OAP proceedings in order to obviate the need for an additional hearing session in the
Theory 2 test cases, as petitioners had requested the opportunity to question both experts in person and
they did not appear as witnesses at the test case hearing. See Order, issued in the OAP docket on July
3, 2008, at 2.
17[A.K’s father] is an attorney who has represented more than 100 Vaccine Act petitioners on claims that
vaccines caused autism spectrum disorders, as well as petitioners in other types of vaccine injury claims.
A.K.’s case was originally filed by Steven Tannenbaum, who was replaced by PSC Executive Committee
member Thomas Powers. After petitioners withdrew as a test case, Mr. Powers withdrew from
representation. For about 19 months, [A.K.’s father] represented himself, his wife, and his son, before Mr.
John McHugh entered an appearance. Although [A.K.’s father] was represented by Mr. John McHugh
and Ms. Helen Sturm at the causation hearing, [A.K.’s father] remained actively involved in the
presentation of his son’s case (see, e.g., Transcript [“Tr.”] at 139, 261-62, 1386, 1389, 1492, 1495, 1515)
and occasionally attempted to interpose objections (see, e.g., Tr. at 326).

                                                     6
appearance to facilitate communication with the court, but that he was actively seeking
another attorney to pursue A.K.’s claim. See Status Report, filed July 1, 2008 (ECF No.
45). Although respondent’s counsel later objected to [A.K.’s father’s] appearance,
arguing that the case should be designated as pro se, I allowed [A.K.’s father] to
remain attorney of record while he searched for representation. Order, issued Nov. 7,
2008, at 1 (ECF No. 50).18

         For about 19 months, [A.K.’s father] attempted to find new counsel to represent
A.K. He filed numerous status reports requesting enlargements of time and updating
me on his progress (or lack thereof). See, e.g., Status Report, filed Aug. 4, 2009 (ECF
No. 61). He filed medical records as they were created or became available. See Pet.
Exs. 31-33 (ECF Nos. 51-52, 65). Other than the filing of medical records, petitioners
did little to advance their claim during the period in which [A.K.’s father] was attorney of
record.

        I continued to press [A.K.’s father] to move his son’s case toward resolution
during this period, noting that when he withdrew from the OAP and indicated a desire to
proceed as an individual case, he was no longer able to claim the benefit of being in the
OAP “holding pattern” to avoid his obligation to prosecute his son’s claim. Perhaps in
frustration with my insistence that petitioners either needed to find substitute counsel or
otherwise prosecute A.K.’s case themselves, [A.K.’s father] voiced a desire to return the
case to the OAP during a status conference on November 3, 2008. I directed
petitioners “to file a written motion requesting their case be redesignated as an OAP
case as soon as possible.” See Order, issued Nov. 7, 2008, at 1 (ECF No. 50).
Petitioners never filed that motion.

          2. Securing Representation.

        On January 5, 2010,19 John F. McHugh filed a motion to be substituted as
counsel in this case, and I granted the motion on January 7, 2010. However, the glacial
pace of progress toward a causation hearing continued for many months thereafter. Mr.
McHugh’s representation has been marked with missed deadlines, repeated requests
for delays, late filings, and difficulties in properly designating and filing exhibits. His
failure to meet deadlines nearly cost petitioners the opportunity to fully litigate their son’s
claim.

       In the first two months Mr. McHugh represented petitioners, he missed both
deadlines set for status reports informing me that he had met with petitioners and was
ready to discuss the way ahead in this case.20

18The practical reason to allow [A.K.’s father] to enter an appearance as attorney of record was to
continue to allow documents to be filed electronically. [A.K.’s father] was (and is) an attorney admitted
to the bar of the Court of Federal Claims. I did caution him, however, that it was unlikely he could be
paid attorney fees for his work on his son’s case.
19   Mr. McHugh filed a defective motion to substitute as counsel on December 2, 2009 (ECF No. 73).
20
 I had an initial status conference with Mr. McHugh more than two weeks after his notice of appearance
was properly filed. See Order, issued Jan. 20, 2010, at 1 (ECF No. 76). He informed me he had not yet

                                                      7
      Between January and August 2010, petitioners’ counsel 21 did very little to
advance the case. Although he reported in March 2010 that he had retained an expert22
who was reviewing the case and expected the expert to produce a report in about two to
two and one half months (Status Report, filed Mar. 5, 2010 (ECF No. 78)), Dr.
Kinsbourne’s very cursory report was not filed until October 26, 2010 (ECF No. 100).

       At the next status conference, held about 90 days later to allow Dr. Kinsbourne
time to prepare his expert report, petitioners indicated that they intended to file an
application for interim costs due to the significant fees involved in retaining medical
experts. See Order, issued June 8, 2010, at 1 (ECF No. 79). It became apparent
during the conference that petitioners had not filed all medical records in their
possession. See id. Thus, I ordered petitioners to file all remaining medical records by
June 18, 2010; any application for interim fees and costs by July 23, 2010; and a status
report informing me of their progress in obtaining expert reports by August 9, 2010. See
id.

        Petitioners filed medical records and a notice of compliance (ECF Nos. 93, 95)
on June 16 and 17, 201023 and an out of time24 status report (ECF No. 96) on August
13, 2010. In their status report, petitioners informed me that (1) Dr. Kinsbourne was
unable to complete his expert report as he was awaiting further diagnostic tests; (2) Dr.
Kinsbourne could not specify when his expert report would be completed; and (3)
petitioners were pursuing another unnamed expert. Status Report, filed Aug. 13, 2010,
at 1-2 (ECF No. 96). Petitioners suggested that they file monthly status reports until

met with petitioners or familiarized himself with the case and estimated that he needed an additional thirty
days to do so. See id. I scheduled another status conference for February 19, 2009 and ordered
petitioners to file a status report informing me that they had met with counsel and discussed their case by
February 12, 2010. Id. Petitioners missed this deadline. On February 18, 2010, I cancelled the status
conference scheduled for February 19, 2010, ordered Mr. McHugh to obtain A.K.’s medical records and
familiarize himself with the case as soon as possible, and ordered petitioners to file a status report
indicating that Mr. McHugh was ready to proceed by March 4, 2010. See Order, issued Feb. 18, 2010
(ECF No. 77). Petitioners missed the deadline, but filed a late status report indicating that Mr. McHugh
was reviewing A.K.’s medical records and that Dr. Marcel Kinsbourne had been retained as an expert and
was reviewing the medical records as well.
21All future references to petitioners’ counsel in this ruling are to Mr. McHugh, petitioners’ attorney of
record. Ms. Helen Sturm, an attorney associated with Mr. McHugh, also appeared on behalf of
petitioners at the hearings.
22 Doctor Kinsbourne was an expert for petitioners in both the Theory 1 and 2 test cases and, as I noted
in Snyder, 2009 WL 332044, at *12, was something of a professional witness in Vaccine Act cases. He
was thus well acquainted with the medical literature pertaining to both vaccines and autism.
23 Petitioners attempted to file medical records on June 14, 2010 (ECF Nos. 84-91). However, the
records were struck as they were not properly filed and used an incorrect event code (“15 week
stipulation status report.”) On June 16, 2010, petitioners properly filed Pet. Exs. 34-36. Identical records
were filed again on June 17, 2010 (ECF Nos. 93, 95).
24Petitioners’ status report was due on August 9, 2010. Petitioners were reminded of the process used to
request additional time under Vaccine Rule 19(b) and warned that future out of time filings would be struck.
See Order, filed Aug. 18, 2010, at 1, n.1.

                                                        8
their expert reports were filed. Id. at 2.

       I rejected this suggestion25 and, instead, ordered petitioners (1) to identify their
potential expert and outline the steps taken to contact the expert, (2) to file a status
report informing me when Dr. Kinsbourne had received the medical records he needed
and when his report could be filed, and (3) to inform me if Dr. Kinsbourne could not
complete his expert report in seventy-five days and, if so, to file a letter from Dr.
Kinsbourne explaining why and providing a date when his report would be completed.
Order, filed Aug. 18, 2010, at 1-2 (ECF No. 97). Petitioners failed to meet any of these
deadlines.

F. Dismissal of Petitioners’ Claim.

        During the period in which [A.K.’s father] was attorney of record and while Mr.
McHugh was attempting to familiarize himself with this case, the OAP test case
decisions were issued. Thereafter, many litigants, particularly those who had
proceeded on the thimerosal theory (Theory 2), dismissed their claims. The PSC had
not sought review of the Theory 2 test case decisions by the special masters, thus
effectively concluding the OAP litigation of this theory. Many attorneys who were
representing the test case litigants were seeking to withdraw from representation, based
on their assessment that the causation theories they had pursued were no longer
viable.

       Against this backdrop, petitioners’ apparent inability to find a doctor other than
Dr. Kinsbourne willing to opine or to obtain a report on causation from Dr. Kinsbourne,
coupled with the repeated missed deadlines, signaled to me that they had problems
with their case. Accordingly, after petitioners missed the deadlines set forth in my
August 18, 2010 order, I ordered them to show cause why their case should not be
dismissed for failure to prosecute and comply with court orders. See Order to Show
Cause, issued Sept. 3, 2010 (ECF No. 98). After petitioners ignored the deadline in the
show cause order, I dismissed their petition on October 13, 2010.

G. Motion for Reconsideration.

       Petitioners filed a motion on October 26, 2010, asking me to reconsider my
decision dismissing their claim for insufficient proof and failure to prosecute.26 After
allowing the parties to present their arguments,27 I granted petitioners’ motion for

25  I viewed petitioners’ request to file monthly status reports as an effort to obtain more delays in the
litigation of their causation claim. More than two years after petitioners had withdrawn as an OAP test
case and indicated that they intended to proceed independently on their case, they had still not filed any
report (other than Dr. Mumper’s) that reflected a causation theory implicating vaccines as causal.
26 With their motion for reconsideration, petitioners also filed additional evidence, declarations from
[A.K.’s father, A.K.’s mother], and treating physician Dr. Marvin Boris as well as some medical literature
and the long-delayed report from Dr. Kinsbourne. See Pet. Exs. 37-56.
27See Respondent’s Response, filed Nov. 3, 2010 (ECF No.102); Petitioners’ Reply, filed Nov. 6, 2010
(ECF No. 104).

                                                      9
reconsideration. See Order, issued Nov. 12, 2010, at 2 (ECF No. 106).28 I
subsequently redacted, at petitioners’ request, portions of the order granting the motion
for reconsideration and withdrawing my dismissal decision.

H. Request for Pre-Payment of Interim Costs.

        Following my withdrawal of the October 13, 2010 decision dismissing petitioners’
claim, I ordered petitioners to file a status report informing me of the date by which they
expected to file the report of their new expert, Dr. Richard Frye, and an “amended
petition clarifying their theory of causation.” Scheduling Order, issued Nov. 15, 2010, at
1 (ECF No. 107). In response, petitioners filed a motion seeking additional time to file
their amended petition, pre-approval of Dr. Frye as an expert, and interim costs in the
amount of $5,00029 to be paid as a retainer to Dr. Frye. Motion, filed Nov. 30, 2010, at 6
(ECF No. 109). On January 28, 2011, I granted the motion for additional time to file an
amended petition and awarded interim costs in the amount of $5,000.30 Decision,
issued Jan. 28, 2011. This decision was later withdrawn as moot, at 10 (ECF No. 121);
see also Order, issued Feb. 28, 2011 (ECF No. 128) (ordering the decision withdrawn)
because Dr. Frye could no longer opine or testify, based on changed employment.

I. Petitioners’ First Amended Petition.

     Petitioners filed their first amended petition on February 28, 2011. First
Amended Petition (ECF No. 126).

         A few weeks later, petitioners indicated they had retained Yuval Shafrir, M.D. and
requested an additional sixty days to file his report.31 Status Report, filed Mar. 9, 2011
(ECF No. 129). After petitioners filed Dr. Shafrir’s expert report,32 I ordered respondent
to file an expert report, supplemental Rule 4 report, and any evidence from the OAP
upon which she intended to rely. See Order, issued July 12, 2011. Respondent filed

28Because I granted petitioners’ motion and ordered my decision to be withdrawn, I denied as moot
petitioners’ motion (ECF No. 101) to redact portions of the October 13, 2010 decision.
29
 This amount was based on an hourly rate of $500 and, thus, constituted prepayment for ten hours of
work.
30 I also ordered petitioners to file “a bill documenting the charge and payment of Dr. Frye’s retainer” by
no later than February 28, 2012 and a more detailed bill within sixty days of the filing of Dr. Frye’s expert
report. On February 7, 2011, respondent filed a motion for reconsideration which I denied. See Order,
filed Feb. 23, 2011, at 5 (ECF No. 124). However, I withdrew my decision awarding interim costs on
February 28, 2011 after petitioners informed me that Dr. Frye was no longer opining in this case. See
Order, filed Feb. 28, 2011 (ECF No. 128).
31Petitioners’ counsel reiterated this request in a status conference I held that day. Respondent did not
object to the request. See Order, issued Mar. 9, 2011 (ECF No. 130). I granted the delay requested.
32Petitioners filed Dr. Shafrir’s expert report and references on July 7, 2011. Pet. Ex. 63, Tabs 1-22 (ECF
NO. Nos. 135-141). Because they had failed to file Dr. Shafrir’s expert report as a separate attachment,
they re-filed the report and first four references on July 8, 2011. See Pet. Ex. 63, Tabs 1-4 (ECF No.
142).

                                                      10
her Rule 4 report and OAP evidence as ordered on October 10, 201133 but requested
additional time to file her expert reports. See Motion, filed Aug. 5, 2011 (ECF No. 144).
I granted respondent’s request, allowing her until November 14, 2011 to file her reports.
Order, issued Aug. 5, 2011.

      Prior to respondent’s deadline, petitioners informed me that they had retained
another expert, Fran. D. Kendall, M.D. and expected to file her report in approximately
two months. See Status Report, filed Oct. 20, 2011, at 1-2 (ECF No. 147).

       In November 2011, respondent filed expert reports from Gerald Raymond, M.D.,
Judith Miller, Ph.D., and Christine McCusker, M.D. Respondent also indicated she
would be filing a report from a mitochondrial disorder expert after Dr. Kendall’s report
was filed.34 In December 2011, petitioners filed Dr. Kendall’s expert report and
references. See Pet. Exs. 65-92, filed Dec. 21, 2011.

J. Preparations for Hearing.

       On January 13, 2012, I held a status conference with the parties to discuss any
additional expert reports they intended to file. See Order, issued Jan. 13, 2012, at 1
(ECF No. 151). Petitioners indicated that they wanted to obtain an expert on pediatric
development and an expert on oxidative stress. I discussed dates by which the parties
should have all expert reports filed and indicated that the case should be ready for a
hearing in November 2012. Id. I ordered the parties to discuss potential hearing dates
with their experts and to propose dates for a hearing. Id.

        Respondent proposed two weeks in February 2013, but petitioners failed to
convey their preferred dates. See Order, issued Feb. 2, 2012 (ECF No. 152). Once
petitioners concurred with respondent’s proposed hearing dates, I set the hearing for
February 17-27, 2013, in Washington, DC. Pre-Hearing Order, issued Feb. 3, 2012
(ECF No. 154).

       On March 14, 2012, respondent filed expert reports responsive to Dr. Kendall’s
opinions from Bruce H. Cohen, M.D. and Kendall B. Wallace, Ph.D. See Res. Exs. SS-
VV.

        From late February to July 2012, petitioners filed a series of status reports
detailing their efforts to find experts in the areas of oxidative stress and child
development. In June, petitioners informed me that A.K.’s pediatrician, Dr. Heddy
Zirin,35 would be testifying in this case but they still were seeking a medical expert in

33See Res. Ex. LL (ECF No.145) (testimony from several OAP witnesses explaining autism spectrum
disorders); Respondent’s Second Rule 4 Report (ECF No.146), recommending against compensation.
34I had permitted respondent to defer filing her expert reports until after Dr. Kendall’s report was filed.
Scheduling Order, issued Oct. 24, 2011, at 1 (ECF No. 148).
35Doctor Zirin never testified. Petitioners indicated at the April 9, 2013 pre-hearing status conference that
they did not intend to call her.

                                                       11
oxidative stress. Status Report, filed Jun. 1, 2012, at 1 (ECF No. 158). The following
month, petitioners informed me that Richard Deth, Ph.D. would be testifying as an
expert in oxidative stress and Mary Megson, M.D. would be testifying as a
developmental pediatrician. Status Report, filed Jul. 31, 2012, at 2 (ECF No. 160).36
Petitioners also informed me that the hearing, which had been set six months earlier,
would have to be delayed. They explained that their attorney was lead counsel in a civil
case in Nevada which the judge had “set a firm trial date” which conflicted with the
hearing date for this case.37 Id. at 1.

       Ultimately, I bifurcated the hearing in this case, setting a fact hearing to take the
testimony of petitioners and treating physicians in New York City, NY on December 12-
13, 2012 and setting the entitlement hearing at which experts would testify in
Washington, DC for April 22-30, 2013. Pre-Hearing Order, issued Aug. 16, 2012, at 2
(ECF No. 166). I ordered petitioners to file all expert reports by September 14, 2012
and respondents to file all expert reports by November 13, 2012. Id.

       Once again, petitioners did not file their reports by the deadline I had imposed.
Expert reports from Drs. Megson and Boris were filed on September 26, 2012 and from
Dr. Deth on October 29, 2012. See Pet. Exs. 107-108; 117, Tabs 1-55. Since I had
extended petitioners’ deadline for filing their expert reports, I adjusted respondent’s
deadline, ordering her to file all expert reports by December 13, 2012. See Order,
issued Sept. 26, 2012 (ECF No. 172).

K. The December 2012 Fact Hearing.

      I ordered the parties to file their pre-hearing submissions for the fact hearing by
November 9, 2012. Pre-Hearing Order, issued Sept. 26, 2012 (ECF No. 173). At the
December 2012 hearing, I heard testimony from petitioners, [A.K.’s mother and father].38
Ms. Sturm represented petitioners at the hearing.

36   Petitioners attached CVs for Drs. Deth and Megson to their status report. See Pet. Exs. 95-96.
37 On August 1, 2012, I held a status conference to discuss the scheduling conflict. See Order, issued
Aug. 1, 2012 (ECF NO. 161). I reminded petitioners that I “deliberately set the hearing a year in advance
to give the large number of experts who are expected to testify ample time to make the necessary
arrangements in their clinical practices and research schedules to permit their presence at the hearing.”
Id. Furthermore, I “expressed my concern that petitioners’ counsel failed to inform the trial judge of the
previously set firm hearing date in this case when the jury trial date was being discussed” in the other
case. Id. I ordered the parties to file a joint status report, discussing whether the entitlement hearing
could be held from February 25, 2013 until March 5, 2013 and to determine if we could hear fact
witnesses in December 2012 or January 2013, to shorten the time needed for the entitlement hearing
itself. Id. To say I was concerned by Mr. McHugh’s cavalier disregard of the schedule in this case would
be an understatement. Juggling schedules of experts frequently delays Vaccine Act cases, and this case
had about three times the number of experts generally appearing.
38Two days prior to the hearing, petitioners informed me that due to time constraints for both Dr. Boris
and [A.K.’s mother], Dr. Boris would not be testifying at the fact hearing. Instead, he would be testifying
as both a fact and expert witness at the entitlement hearing in April 2013 in Washington, DC. Petitioners
also decided against calling Dr. Zirin. See Supplemental Pre-Hearing Order, issued Apr. 17, 2013 (ECF
No. 239).

                                                      12
         During [A.K.’s mother’s] testimony, it became apparent that petitioners thought
they had filed documentation regarding A.K.’s receipt of a second dose of influenza
vaccine39 in early December 2001. Tr. at 69-70. I recessed while a copy of this record
(filed later that day as Pet. Ex. 118) was obtained. Tr. at 70-71; see Pet. Ex. 118, filed
Dec. 12, 2012 (ECF No. 188).

L. Second Request for Pre-Payment of Interim Fees and Costs.

       Following the fact hearing, petitioners filed their second motion for interim costs.
Arguing that they had expended $17,000.00 litigating their claim, petitioners requested
$81,750.00 to cover costs they expected to incur during the April 2013 entitlement
hearing. Motion, filed Jan. 10, 2013, at 3-5, 11 (ECF No. 190). The parties were unable
to agree on an award of interim costs, but respondent indicated that she would not
object to an award of interim fees and costs in the amount of $30,000.00, representing
payment for attorneys’ fees. Status Report, filed Mar. 22, 2013, at 1-2 (ECF No. 209).
On March 27, 2013, based on the documentation submitted for amounts already
expended, I awarded interim costs in the amount of $24,108.12. Decision (ECF No.
215). Neither party filed a motion for review of that decision.

M. Preparation for the April 2013 Entitlement Hearing.

        On February 21, 2013, I ordered the parties to file any additional exhibits and
medical literature by March 22, 2013, and pre-hearing briefs by April 8, 2013.
Respondent filed their medical literature on March 22, 2013. See Res. Exs. MM, Tabs
20-24; OO, Tabs 1-4; SS, Tabs 1-20; UU, Tabs 17-20; VV. Indicating that they would
be filing over 100 additional medical journal articles, petitioners requested an extension
of four days. Motion, filed Mar. 22, 2013, at 1 (ECF No. 210). I granted petitioners’
request but warned them that I would not consider additional literature filed after that
date. Order, issued Mar. 25, 2013, at 1 (ECF No. 214); see also Pre-Hearing Order,
issued Feb. 21, 2013, at 1 (ECF No. 199) (indicating that, absent a compelling reason, I
would not consider late filed medical literature). Petitioners filed their medical literature
on March 26, 2013.40

        A few days later, petitioners filed an unpublished paper regarding the evaluation
and treatment of patients with autism and mitochondrial disorders from Dr. Richard
Kelley at the Kennedy Krieger Institute. This document was not a medical journal article
or medical record; it appeared to be a handout provided to patients or perhaps to
referring physicians. See Pet. Ex. 233, filed on Mar. 31, 2013. Because I had given
petitioners more than adequate notice that, absent a compelling reason, I would not

39At that time, children under two years of age received a split dose of vaccine, half the amount
administered to older children and adults, in two vaccinations about one month apart.
40The articles filed were labeled as exhibits 124-67, 171-209, and 211-31. Petitioners correctly noted
that exhibit numbers 169-70 and 210 had been assigned to previously filed exhibits. See Pet. Exs. 169-
70, 210, filed on Mar. 22, 2013 (ECF No. 211) (attachments to petitioners’ status report regarding interim
costs).

                                                     13
consider medical literature filed after the deadline, I ordered the exhibit struck.41 Order,
issued Apr. 9, 2013; see also audio transcript of Apr. 9 2013 status conference at 2:35
(petitioners’ counsel agreeing that the article was “not critical” and that there was no
compelling reason for the late filing).

       Also on March 31, 2013, petitioners also filed a motion requesting that I issue a
subpoena to compel an expert in another case to produce his expert report from that
case and any other material or information “deem[ed] appropriate to accomplish the
purposes of the Vaccine Act and justice.” Motion to Issue Subpoena, filed Mar. 31,
2013, at 7 (ECF No. 216). I ordered respondent to file a response to petitioners’ motion
by April 8, 2013, reiterating that the parties’ pre-hearing submissions were due on the
same date. Order, issued Apr. 1, 2013 (ECF No. 218). Respondent filed her response
(see ECF No. 224). I orally denied the motion. Apr. 9, 2013 status conference at 2:33.

        On April 1, 2013, just three weeks prior to the start date for the causation
hearing, petitioners requested leave of court to file a second amended petition. Motion,
filed Apr. 1, 2013, at 1 (ECF No. 219). Petitioners attached the proposed amended
petition as Pet. Ex. 234. I granted this motion and the amended petition [“2d Amend.
Petition”] was filed on April 17, 2013 (see ECF No. 237); see also Apr. 9, 2013 status
conference at 2:33-34 (permitting filing of the amended petition, but noting that
petitioners were now alleging as causal vaccines that were not on the Vaccine Injury
Table at the time their short-form petition was filed).

         Petitioners then requested leave of court to file a recently published medical
journal article.42 Because the article was not available until January 25, 2013, I granted
petitioners’ motion. Petitioners filed the article on April 17, 2013. See Pet. Ex. 235
(ECF No. 238); see also Apr. 9, 2013 status conference at 2:36-38 (permitting the late
filing, despite the earlier on-line availability of the article).

       The parties filed their pre-hearing submissions on April 8, 2013. ECF Nos. 225-
26, 228-29. Additionally, petitioners filed another document (titled as a motion in limine)
containing numerous requests for relief. See Motions in Limine, filed Apr. 8, 2013 (ECF
No. 227). Because the deadline for respondent’s response to petitioners’ motions fell
on the first day of the planned hearing, I extended respondent’s deadline until two
weeks after the hearing was scheduled to conclude. Order filed Apr. 9, 2013. I discuss
and rule on these motions in Section II, below.

       I held a status conference on April 9, 2013 to discuss preparations for the
upcoming hearing. Following the call, respondent filed the updated CV for Dr. Raymond
(see Res. Ex. NN, filed Apr. 10, 2013 (ECF No. 231)) and a status report listing the
videotape clips she intended to use at the hearing (see Status Report, filed Apr. 12,
41   I reviewed the document prior to ordering it struck.
42 When   petitioners originally filed their motion, they incorrectly used the exhibit number already assigned
to their second amended petition (Pet. Ex. 234). See Motion, filed Apr. 4, 2013 (ECF No. 222). Thus,
petitioners later asked that I strike that motion and allow the article to be filed out of time as exhibit 235.
Motion, filed Apr. 9, 2013, at 3 (ECF No. 230).

                                                            14
2013 (ECF No. 232)). Petitioners filed the redacted videotape footage they intended to
use at the hearing. See Notice filed Apr. 12, 2013 (ECF No. 233) (listing Pet. Exs. 236
and 236A).43 Petitioners also filed the declaration of the technician who prepared the
redacted videotape footage. See Pet. Ex. 237, filed Apr. 18, 2013 (ECF No. 241).

N. The April 2013 Entitlement Hearing.

       Two days before the entitlement hearing, petitioners requested leave to file out of
time a recently published article related to the research being conducted by one of their
experts, Dr. Deth. Motion, filed Apr. 20, 2013 (ECF No. 243) (requesting to file Pet.
Exs. 238 (article) and 238A (article’s abstract)). I granted that request.

       During the second day of the hearing, petitioners filed copies of the slides which
Dr. Deth would be referencing while testifying and another recently published article
upon which he intended to rely. See Pet. Exs. 239 and 240, filed Apr. 24, 2013 (ECF
Nos. 244 and 245). The evening before the last day of the hearing, petitioners filed a
motion for leave to file out of time another recently published article. See Motion, filed
Apr. 28, 2013 (ECF No. 255) (requesting to file Pet. Ex. 241).44

      Respondent filed the updated CV of Dr. Cohen and copies of the presentations
used by Drs. Jones, Johnson, and Raymond. See Res. Exs. TT, Tab 1; GGG; HHH; III.

O. Post Hearing Motions and Briefs.

        Following the entitlement hearing, I ordered petitioners to file the medical
literature referenced at hearing indicating that I “may or may not consider these articles
but must see the entire article before making that determination.” Order, issued May 1,
2013, at 1 (ECF No. 257). This order was necessary because Dr. Deth cited many
medical journal articles not previously filed on the PowerPoint slides he used during his
testimony. I also allowed respondent to respond to the late-filed exhibits. Id.

       Because petitioners informed me they had found an expert in child development
to replace Dr. Megson, who had been unable to testify due to illness, and estimated
they could file a report from their new expert within 60 days, I set a deadline for the
replacement expert’s report and a deadline 30 days thereafter for a written response

43 Petitioners filed the notice of intent to file this video footage (on a computer hard disk) on April 12, 2013.
Notice (ECF No. 233). However, the docket did not reflect receipt of the hard disk and no copy of
it was received at OSM from the Clerk of Court. The original court file in this case did not contain a hard
disk. Nevertheless, I was able to view the videos discussed at the hearing. In anticipation of issuing this
ruling and the entitlement decision in this case, I ordered petitioners to file another copy of the video clips
shown at the hearing to ensure that the record is complete. See Order, issued Aug. 20, 2015 (ECF No.
315). Based on the information supplied by petitioners, it appears that the hard disk was received, but
somehow misplaced by the Clerk’s Office. See Status Report, filed Aug. 20, 2015 (ECF No. 317).
Pursuant to my order, petitioners provided another copy of the videos (this time on a jump drive) on Aug.
21, 2015. See Notice, filed Aug. 20, 2015 (ECF No. 318).
44Petitioners originally filed their motion on April 27, 2013 but asked that I strike that motion on April 28,
2013. See ECF No. Nos. 253 and 254.

                                                       15
from respondent. Order, issued May 1, 2013, at 1-2 (ECF No. 257). Petitioner later
filed a status report indicating they “w[ould] not be submitting another expert’s report
and will rely upon those submitted.” Status Report, filed July 1, 2013 (ECF No. 272).
They then asked that Dr. Megson be allowed to testify by video in late summer or fall
(see Status Report, filed July 17, 2013, at 1 (ECF No. 274)) but changed their minds
approximately two weeks later, citing excessive costs and indicating they would rely on
Dr. Megson’s expert report (see Status Report, filed July 30, 2013 (ECF No. 275),
without the need for further testimony.

       Finally, I reiterated my instructions at the close of the hearing that I would order
the parties to file simultaneous post hearing briefs once the record was complete and
reminded respondent that her deadline to respond to petitioners’ motions in limine was
May 14, 2013. Order, issued May 1, 2013, at 1-2 (ECF No. 257). Respondent filed her
response on May 13, 2013 (see ECF No. 258).

        On May 31, 2013, petitioners filed the medical literature referenced in Dr. Deth’s
PowerPoint presentation but, instead of assigning each article a new exhibit number,
petitioners labeled them as references to the slide in which the article was mentioned.
See (ECF No. 260-262). I ordered petitioners to assign each article its own exhibit
number and to file an updated exhibit list reflecting the new exhibit numbers. Order,
issued June 6, 2013, at 1-2. Petitioners filed their updated exhibit list assigning exhibit
numbers 242-266 to the medical literature on June 25, 2013. See ECF No. 271.

        Less than one month later, petitioners sought in a status report to file yet another
article out of time. They assigned the article an exhibit number which had been used
previously (Pet. Ex. 237). Status Report, filed July 17, 2013 (ECF No. 274). Because
petitioners later filed an appropriate motion, albeit out of time, to file the same article,
correctly labeled as exhibit 273, (see Motion, filed Apr. 24, 2013 (ECF No. 293)),
petitioners’ July 17, 2013 request via status report to permit the late filing of medical
literature is moot.

        In August 2013, respondent filed the supplemental report of Dr. Johnson
pertaining to the medical literature, previously unfiled, that Dr. Deth had referenced in
his slide presentation at the hearing. See Res. Ex. JJJ. At that point, I filed Court
Exhibit [“Court Ex.”] I, and solicited any comments, supplemental expert reports or
arguments concerning the filing.45 Order, issued Sept. 3, 2013 (ECF No. 277). I also
set deadlines for filing any additional evidence in this case. Post Hearing Order, issued
Sept. 9, 2013, at (ECF No. 278). Respondent filed supplemental expert reports from
Drs. Cohen and Wallace responding to the Wolf & Smeitink article, Court Ex. I. See
Res Exs. KKK, LLL, filed Sept. 30, 2013 (ECF No. 279). Petitioners filed a
supplemental expert report from Dr. Kendall responding to Court Ex. I, but again re-

45N. Wolf & J. Smeitink, Mitochondrial Disorders: A proposal for consensus diagnostic criteria in infants
and children, NEUROL. 59: 1402-06 (2002) [hereinafter “Wolf & Smeitink, Court Ex. I”]. Strictly speaking, it
was unnecessary to file this document as a court exhibit, as it had been filed by respondent as Res. Exs.
SS, Tab 19 and UU, Tab 15. However, I wanted both parties to address the diagnostic criteria specific to
children set forth in the article and in the supplemental materials referenced in the article.

                                                     16
used an exhibit number. See Pet. Ex. 238, filed Oct. 3, 2013 (ECF No. 280).
Petitioners also filed a written response from Dr. Deth to comments made by Dr.
Johnson, once again assigning the response an exhibit number which had been
previously used. See Pet. Ex. 239, filed Oct. 8, 2013 (ECF No. 281). Later, on January
16, 2014, petitioners moved to strike and replace Dr. Kendall’s supplemental expert
report, labeling it as Pet. Ex. 269 (see ECF No. 287). Thus, although there are no
longer two exhibits labeled Pet. Ex. 238, there are still two exhibits labeled Pet. Ex. 239.

      On November 15, 2013, I indicated that the evidentiary record was complete and
ordered the parties to file post hearing briefs. Post Hearing Order (ECF No. 282).

      Following my order, petitioners attempted to file four more articles out of time.
See Motion, filed Jan. 14, 2014 (ECF No. 284) (requesting to file Pet. Ex. 240);46
Motion, filed Apr. 24, 2014 (ECF No. 293) (requesting to file Pet. Exs. 271-73).
Because I had ordered the evidentiary record closed in my November 15, 2013 order, I
denied both of petitioners’ motions. Order, issued Apr. 28, 2014, at 1-2 (ECF No. 294).

       After multiple extensions of time, the parties filed their post hearing briefs on May
5, 2014. Petitioners attached a table setting forth multiple test results to their brief. See
Pet. Ex. 274. Petitioners also requested that I strike the testimony of Dr. Miller, one of
respondent’s experts on autism diagnosis. Pet. Post-Hearing Memo, at 34 (ECF No.
297). I respond to that request in the rulings below.

        The parties filed responses to the opposing party’s brief on June 16, 2014. To
their response, petitioners attached new three exhibits. See Pet. Ex. 274-275 and 279
(ECF No. 302). Petitioners again used an exhibit number (274) which had previously
been used. The exhibit filed on June 16, 2014 is a notice of a funding opportunity for
research regarding autism. See Pet. Ex. 274, filed June 16, 2015 (ECF No. 302).

        After the filing of the post-hearing reply briefs, petitioners again requested to file
out of time the four exhibits I had disallowed in April 2014 (see Order, issued Apr. 24,
2014, ECF No. 294), the three exhibits attached to their response to respondent’s post
hearing brief, and six additional articles. Motion, filed June 17, 2013 (ECF No. 303;
Motion, filed June 26, 2014 (ECF No. 306).47 In July 2014, respondent filed a response
to petitioners’ motions and petitioners then filed a reply.

46Petitioners originally filed an “unprocessed copy of Exhibit 240” but attempted to correct their mistake in
an errata filed that same day (Errata, filed Jan 14, 2014 (ECF No. 285)) and then made a motion to strike
(Motion, filed Jan. 14, 2014 (ECF No. 286)). Another article labeled Pet. Ex. 24 (Wong) had been used
during the hearing. Petitioners eventually relabeled the Rose article (the subject of the abortive filings in
January 2014) as Pet. Ex. 270.
47
 Originally, [A.K.’s father] filed this motion. See Motion, filed June 26, 2014 (ECF No. 305). Since he
was not the attorney of record, I struck his filing. See Non-pdf Order, filed June 27, 2014.

                                                      17
                          II. Rulings on Outstanding Motions.

A. Overview.

       With regard to most of the motions filed prior to the hearing in this case, I either
ruled orally or deferred ruling until I could consider the proffered evidence in context of
the testimony and other evidence properly filed. In orally denying the motion to
subpoena an expert witness, see audio transcript at 2:33 (Apr. 9, 2013 status
conference), I indicated that I would issue a written ruling at a later time.

        Although petitioners characterized their motions as motions in limine, most were
not motions to preclude the use of evidence. See BLACK'S LAW DICTIONARY (10th ed.
2014) (defining a motion in limine as a “pretrial request that certain inadmissible
evidence not be referred to or offered at trial.”). Rather, petitioners sought many
different types of relief. Most of these motions were filed on April 8, 2013, at a time
when both respondent’s counsel and I were engaged in preparation for a lengthy
hearing involving multiple experts. Petitioners had also just filed a new petition
“clarifying” the theory of causation, many of the medical journal articles they filed had
not been discussed by their experts, and there were extensive medical records in this
case. Given the deluge of filings and the imminent hearing, I deferred ruling on most
motions until after the hearing, when respondent would have adequate time to consider
and respond and I could consider the issues in the context of the evidence adduced at
the hearing. See generally, recording of status conference held April 9, 2013, at 2:32.

        Petitioners’ penchant for filing multiple motions requesting the same relief and
their impaired ability to properly file exhibits have needlessly complicated the docket in
this case. Sorting out the exhibit numbers alone has consumed considerable time and
effort. During an April 9, 2013 status conference, I told the parties that a ruling on
petitioners’ motions would be issued at the time of or before issuing a decision on
causation. Audio Tr. at 2:32-33. As reflected below, their attempts to drag what
happened in another Vaccine Act case—one decided and compensated as a Table
injury—into the resolution of this causation in fact case, has fruitlessly complicated the
resolution of their motions, as I must address the actual procedural history for both the
instant case and the Poling case, No. 02-1466. What actually happened in Poling is far
different from the Poling case they describe.

         Petitioners’ counsel did not appear to understand that closing the record (which
was not done until long after the hearing) meant that no further evidence should be filed,
absent truly extraordinary circumstances. Petitioners never adequately explained in any
of their requests to file medical journal articles (and often, not even newly published
articles) why reopening the record to consider this evidence was truly necessary to a fair
trial or a just result. I cannot identify even one of the articles filed after the evidence
closed that was not either cumulative of the evidence already presented or which was
truly late-breaking and highly significant. The need to read, re-read, and compare late-
filed journal articles to the evidence already filed (which included at least 100 journal
articles that no expert ever mentioned in a report or testimony) has materially

                                             18
contributed to the delay in issuing a decision in their son’s case. As respondent has
noted, perhaps that was petitioners’ intent, in the vain hope that more delay would work
in their favor.

        I now issue the written rulings on all of petitioners’ outstanding motions and
clarify why some of the filed motions are now moot.

B. Resolving Issues Surrounding the Poling Case.

         The motion to subpoena, depose, or otherwise compel the expert testimony of
Dr. Andrew Zimmerman and the motion to compel respondent to concede the medical
theory advanced by petitioners are both bound up in the issues presented in another
OAP case, one brought by Dr. Jon Poling and his wife on behalf of their minor
daughter.48 Understanding the background of this other, widely publicized case is
critical to placing petitioners’ motions in the case at bar in context.

        1. Background and History of the Poling Case.

       Petitioners in this case (and at least one other case)49 have formally argued that
respondent’s concession of entitlement to compensation in the Poling case, No. 02-
1466,50 renders the government unable to contest entitlement in theirs. Their claim that
respondent should be judicially estopped from challenging their causation theory stems
from the Poling case, which was settled in 2010 but conceded by respondent in 2008.

       The facts of the Poling case and its relationship to this one are drawn from two
pieces of evidence properly filed in the instant case: a medical journal article filed by
both parties and a highly unusual commentary by the editor-in-chief of the medical
journal in which the article first appeared. Additionally, I reference the publically-
available docket entries in Poling and the posted rulings and decisions by the special
master. See § 12(d)(4)(b), requiring decisions of the special master to be disclosed and
the “E-Government Act,” (see n.1, supra) (requiring reasoned rulings of courts to be
publically available).

48Although the minor’s name has been disclosed publically, I will not use it in this ruling or in the
entitlement decision to follow.
49See Vernacchio v. Sec’y, HHS, No. 08-504V, 2015 WL 1951051 (Fed. Cl. Spec. Mstr. Apr. 10, 2015).
Of note, [A.K.’s father] is the counsel of record in Vernacchio. Although not raised via a
motion regarding judicial estoppel, the Poling case and the Poling medical journal case report have been
used by petitioners in several other cases alleging that a vaccine significantly aggravated or triggered a
mitochondrial disorder or dysfunction, as evidence that a vaccine can do so. See, e.g., Miller v. Sec’y,
HHS, No. 02-235V, 2015 WL 5456093 (Fed. Cl. Spec. Mstr. Aug. 18, 2015); Holt v. Sec’y, HHS, No. 05-
0136V, 2015 WL 4381588 (Fed. Cl. Spec. Mstr. June 24, 2015).
50 In citations to the Pacer docket entries in Poling, I will identify the case name, the docket number and
the ECF number for the filing at issue. With the exception of the publically available decisions and rulings
in Poling (i.e., those appearing on the Court of Federal Claims website or WestLaw), none of the matters
discussed herein with regard to Poling delve into the non-public filings. All other ECF numbers refer to
matters filed in the instant case.

                                                       19
       In October of 2002, Terry and Jon Poling filed a vaccine injury claim on behalf of
their minor child. The child reportedly experienced symptoms of a developmental
regression within 48 hours of a DTaP vaccination and more symptoms of a similar
nature within five to 15 days of a measles vaccination, both of which were administered
when the child was 19 months of age. The onset of neurological symptoms was within
the periods for a DTaP Table encephalopathy (72 hours) and a measles Table
encephalopathy (5 to 15 days). The child was eventually diagnosed with both autism
and a mitochondrial disorder. Recognizing that the child experienced neurological
symptoms within the time periods required for a Table injury, respondent filed a Rule
4(c) report51 conceding that petitioners were entitled to compensation.

        The journal article, J. Poling, et al., Developmental Regression and Mitochondrial
Dysfunction in a Child With Autism, J. CHILD NEUROL. 21:170-72 (2006), was filed by
both parties.52 I cite to the copy filed as Res. Ex. MM, Tab 14 [hereinafter “Poling, Res.
Ex. MM, Tab 14”]. The article contains a case study of a child who experienced a
regression after receipt of several vaccinations and who thereafter experienced a loss of
skills. This child was later diagnosed with autism and a mitochondrial disorder. The
article also contains an abbreviated analysis of laboratory studies in 159 other children
with ASD diagnoses, as compared to 94 children with neurological disorders other than
ASD, with the stated purpose of demonstrating that other children with ASD diagnoses
might also have mitochondrial disorders. Res. Ex. MM, Tab 14, at 171-72.

         The commentary was filed as Res. Ex. MM, Tab 17: R. Brumback, The Appalling
Poling Saga, J. CHILD NEUROL. 23(9): 1090-91 (2008). The commentary reflected that
Dr. Jon Poling was the petitioner in a vaccine injury claim filed on behalf of his daughter.
He and his co-authors failed to disclose that conflict of interest to the medical journal
where the article was submitted and accepted for publication. The commentary
reflected that a “media frenzy” had ensued when the decision to compensate the child’s
vaccine injury case became public. The commentary’s focus was on the authors’ failure
to disclose the pending injury claim as a conflict of interest. As Dr. Brumback noted:
“Openness and transparency related to any and all potential conflicts of interest is
critical to maintaining the integrity of science in general and of journal quality in

51 As a Vaccine Rule 4 report is “information submitted to a special master or the court in a proceeding on
a petition,” it “may not be disclosed to a person who is not a party to the proceeding without the express
written consent of the person who submitted the information.” § 12(d)(4)(A). Nevertheless, as discussed
in more detail in Section II.B.3(b), infra, a copy of what purports to be the Vaccine Rule 4 report in Poling
was filed by petitioners in this case as Pet. Ex. 57. I note that the public docket in Poling, No. 02-1466,
contains an Amended Respondent’s Report, the contents of which do not appear to have been publically
disclosed. See ECF No. 27, filed on February 25, 2008.
52 Petitioners filed versions of the article published online as Pet. Exs. 40; 63, Ref. 18; and 91. Curiously,
in filing Pet. Ex. 40, petitioners identified it by the name of the last-listed author, Dr. Andrew Zimmerman,
one of the Poling child’s treating physicians, rather than by the name of the first author, Dr. Jon Poling.
Doctor Zimmerman is listed as the senior researcher (the last listed author) on the article. However, the
principal author was Jon Poling, and another author was John Shoffner, the clinician who performed the
mitochondrial disorder testing on A.K. Id. at 2. A third author was Dr. Frye, who was identified at one
point as an expert in this case. The fourth author, Dr. Andrew Zimmerman, is the person petitioners
sought to subpoena as an expert witness.

                                                      20
particular.” Id. at 1090.

       Because the Poling case was settled, there was no entitlement decision
explaining the basis for the action taken in it.53 Instead, on March 6, 2008, the special
master issued an order to proceed to a damages determination. Poling, 02-1466, ECF
No. 35. In July 2010, respondent filed a proffer which Mr. and Mrs. Poling accepted.
Shortly thereafter, then-Special Master Campbell-Smith, who presided over the Poling
case through final resolution of the fees and costs in it, issued a decision awarding
compensation in the amount agreed upon by the parties. See Poling, 02-1466, ECF
Nos. 115, 117, 120, 127 (damages decisions and redacted and re-issued damages
decision). In 2011, Special Master Campbell-Smith awarded attorney fees and costs in
a published decision. Poling v. Sec'y, HHS, No. 02–1466V, 2011 WL 678559, at *1
(Fed. Cl. Spec. Mstr. Jan. 28, 2011). That decision reflects:

        Respondent conceded that petitioners are entitled to compensation based
        on a determination that [the minor child] suffered an injury identified on the
        Vaccine Injury Table, specifically, a presumptive MMR vaccine-related
        injury of an encephalopathy. [The child’s] encephalopathy eventually
        manifested as a chronic encephalopathy with features of an autism
        spectrum disorder and a complex partial seizure disorder as a sequela.

 Id. (emphasis added). The language emphasized makes clear that the Poling case
was compensated based on the presumption of causation that attaches when the Table
injury requirements are met, not on an actual causation or causation in fact basis.
Otherwise, the reference to an injury appearing on the Vaccine Injury Table is
nonsensical, as the only injuries that appear on the Table are those for which
entitlement to compensation is presumed, such as the MMR Table injury of
encephalopathy. See 42 C.F.R. § 100.3(a)(III)(B).

        2. Connections between A.K.’s Case and Poling.

       In their reply to respondent’s filing regarding the motion for reconsideration of my
decision dismissing this petition for failure to prosecute, petitioners filed Pet. Ex. 57, a
document “purporting to be the complete and entire Rule 4 Report filed by the
respondent in Poling.” ECF No. 104 at 3. Petitioners requested disclosure of the actual
Rule 4 report filed in Poling and the expert reports filed in that case, singling out a report
by Dr. Andrew Zimmerman in particular. ECF No. 104 at 4, n.1. They characterized the
Rule 4 report filed in Poling as constituting:

        an admission that the conditions observed in [the minor child] are
        symptoms of mitochondrial disorder and that a vaccination of a person
        with that condition can cause symptoms similar to those evidencing
        autism. The respondent is estopped from taking any position in the instant

53Although respondent apparently conceded entitlement to compensation in her Rule 4 report in the
Poling case, thereafter petitioner filed two expert reports in that case, including one by Dr. Andrew
Zimmerman. See ECF Nos. 22 and 24, Case No. 02-1466.

                                                     21
           case that is inconsistent with the [sic] Poling Rule 4 Report.

ECF No. 104 at 6.

       Petitioners reiterated the arguments made in this reply brief when they filed the
motion on April 8, 2013, seeking application of judicial estoppel or to compel respondent
to admit the validity of their medical theory. See ECF No. 227. They reiterated their
argument concerning their “right” to obtain a copy of Dr. Zimmerman’s report in the
Poling case in their March 31, 2013 “Motion for Leave to Serve a Deposition Subpoena
or Other Appropriate Relief, Including Disclosure of Relevant Evidence.”54 ECF No. 216
at 1.

        In her expert report and at the hearing, petitioners’ mitochondrial disease expert,
Dr. Fran Kendall, placed considerable reliance on the Poling article, Res. Ex. MM, Tab
14. It was one of the two medical journal articles she cited in support of her theory that
vaccines could cause or trigger a mitochondrial regression resulting in an ASD
diagnosis. Pet. Ex. 65 at 7-8. She testified similarly. See Tr. at 254, 285-86. However,
in testimony, she acknowledged that the facts in the Poling case report bore little
resemblance to the facts in the case at bar. Tr. 367-71.

           3. Issues Raised by Petitioners’ Reliance on Poling.

       Petitioners’ reliance on the Poling case raises three issues in the instant case.
The first is their use of documents barred by § 12(d)(4)(A) of the Vaccine Act. The
second is their contention that Dr. Zimmerman can be compelled to offer expert
testimony. The third is their judicial estoppel argument.

                   a. Filings in Violation of the Vaccine Act.

           Section 12(d)(4)55 of the Vaccine Act governs the disclosure of information

54This filing contains a troubling misstatement, in that it claims petitioners learned only on March 30,
2013 that petitioners in Poling filed a report by Dr. Andrew Zimmerman. ECF No. 216 at 1. Their filing of
November 6, 2010 (ECF No. 104) reflected that they were aware of such an expert report filing long
before March 2013. Id. at 4, n.1.
55   Section 12(d)(4) provides:

           (A) Except as provided in subparagraph (B), information submitted to a special master or
           the court in a proceeding on a petition may not be disclosed to a person who is not a
           party to the proceeding without the express written consent of the person who submitted
           the information.

           (B) A decision of a special master or the court in a proceeding shall be disclosed, except
           that if the decision is to include information--

                  (i) which is trade secret or commercial or financial information which is privileged
           and confidential, or

                                                        22
submitted during a vaccine proceeding. The language of § 12(d)(4) is incorporated into
Vaccine Rule 18. Congress added this section in amendments it made to the Vaccine
Act in 1989. P.L. No. 101-239, 103 Stat. 2106.

       The legislative history for the language prohibiting disclosure of information
submitted during vaccine proceedings without written consent (which now appears at §
12(d)(4)(A)) was originally located at the end of the paragraph describing the special
masters’ discovery powers (§ 12(c)(2) (Supp. V 1988)). In the 1989 amendments, this
non-disclosure provision, which abrogated the common law rule that court filings are
open to public scrutiny, was moved to § 12(d)(4)(A) and the new directive requiring the
disclosure of vaccine decisions was added in § 12(d)(4)(B). See H.R. Conf. Rep. 101-
386, at 512-13 (1989), reprinted in 1989 U.S.C.C.A.N. 3018, 3115-16; see also
Castagna v. Sec’y, HHS, No. 99-411V, 2011 WL 4348135, at *6-7 (Fed. Cl. Spec. Mstr.
Aug. 25, 2011) (for a comprehensive discussion of the legislative history of the Vaccine
Act and the 1989 amendments).

        Under § 12(d)(4)(A), information submitted to a special master in a case may not
be disclosed without the express written consent of the party who submitted the
information. Thus, Congress protected any information submitted by a party from public
view, effectively sealing pre-decisional Vaccine Act proceedings. This is a departure
from the common law right of access to judicial records. See, e.g., Nixon v. Warner
Communications, Inc., 435 U.S. 589, 597 (1978) (remarking that “the existence of a
common-law right of access to judicial records” is widely acknowledged, though as “[a]n
infrequent subject of litigation, its contours have not been delineated with any precision.”
The Court also stated that “[i]t is clear that the courts of this country recognize a general
right to inspect and copy public records and documents, including judicial records and
documents” (internal citations omitted).).

        In spite of the explicit language in the Vaccine Act and Vaccine Rule 18,
petitioners filed several documents in this case that they claim were filed in Poling: (1)
the Rule 4 report (Pet. Ex. 57);56 (2) a largely illegible two page document taken from a

                 (ii) which are medical files and similar files the disclosure of which would
        constitute a clearly unwarranted invasion of privacy,

and if the person who submitted such information objects to the inclusion of such information in the
decision, the decision shall be disclosed without such information.
56It does not appear that respondent has formally challenged the admissibility of the Rule 4 report from the
Poling case filed as Pet. Ex. 57 in the instant case, although she may have addressed the issue
obliquely in some filings. While this lack of formal challenge may not constitute the “express written
consent” of the party who submitted this information, the lack of any objection, coupled with respondent’s
reliance on matters contained in Pet. Ex. 57 in at least one document filed in this case (see ECF 308 at 8,
n.8), leads me to treat respondent’s lack of objection as consent. I will also treat respondent’s citation to
Pet. Ex. 57 as an implicit concession that the document is what it purports to be—a somewhat
expurgated version of the Rule 4 report filed in the Poling case. Notwithstanding the public and highly
improper disclosure of this Rule 4 report, Vaccine Rule 4 reports are not intended for public release, and
as such are not drafted with the intent to explain in detail all of the considerations that may lead
respondent to concede a case or to compensate a case based on a litigative risk assessment. The only
way to enforce the clear statutory intent that what a party files remains exempt from public disclosure

                                                      23
website that appears to be a letter written by Dr. Zimmerman (Pet. Ex. 283); (3) a letter
from Dr. Zimmerman to petitioners’ counsel in Poling that appears to address the issue
of sequela of the original Table encephalopathy, also obtained from a website (Pet. Exs.
284 and 285); (4) a mostly illegible copy of a PowerPoint slide which appears to be the
last page of the Zimmerman letter, titled “Dr. Zimmerman’s Second Medical Opinion
Letter”(Pet. Ex. 286); and (5) another copy of the letter from Dr. Zimmerman to
petitioners’ counsel in the Poling case, dated November 30, 2007 (Pet. Ex. 277).

       As articulated in their June 26, 2014 motion to reopen the record and file Dr.
Zimmerman’s report out of time (ECF No. 306), petitioners reiterated their claim that
they learned of Dr. Zimmerman’s report only on March 30, 2013. This claim is
erroneous. See, supra, n.54. In their motion, they acknowledged that the matters filed
in the Poling case remained sealed, speculating that they remained so in order “to
secure a financial settlement for the severely injured minor petitioner.”57 ECF 306 at 8.

         Noticeably lacking in the motion for leave to file Pet. Ex. 277 out of time (ECF
No. 306) and in any of the other filings in this case is any suggestion that the petitioners
in this case secured the ”express written consent” of the persons who submitted Dr.
Zimmerman’s letter or respondent’s Rule 4 report in Poling.

        Another round of briefing ensued on this issue. See ECF Nos. 308, 309.
Respondent noted that the timing of the filing of Dr. Zimmerman’s expert report in Poling
indicated that it was not the basis for respondent’s concession, as the report was filed
after respondent’s first substantive Rule 4 report conceding the case.58 See ECF No.
308 at 8, n.8. Petitioners argued that there was no impropriety in seeking to file Pet. Ex.
277 because it had “been published repeatedly on the internet, and ha[d] been
presented more than once in public events.” ECF No. 309 at 6-7. They argued that
“fundamental fairness and due process of law” compel the admission of Dr.
Zimmerman’s report.

(except to the extent these matters are relied on in a special master’s decision) is to preclude the filing of
documents from one case in another case, absent that “express written consent.” However, as
respondent has used that Rule 4 report as a sword in this case, I will not preclude its use by petitioners. I
therefore find petitioners’ request for disclosure of the Rule 4 report in Poling (see ECF No. 104 at 4, n.1)
moot as the evidence sought is already before me.
57Once again, a review of the publically available docket in Poling reveals that on July 20, 2009,
petitioners filed a motion to withdraw a previously filed motion (ECF No. 86). After additional filings by
both sides (see ECF Nos. 88 and 90), the presiding special master granted a “Motion for Appropriate
Relief,” filed by respondent on June 26 2008 (referencing ECF No. 61) and a granted “Motion to Withdraw
Motion for Complete Transparency” filed by petitioners (referencing ECF No. 86). See Order issued Aug.
20, 2009 (ECF No. 92). The decision awarding damages was not issued until nearly a year later (July 21,
2010), which is hardly suggestive of a quid pro quo.
58 Respondent filed an initial Rule 4 report in Poling in January 2003. It was likely a pro forma report
reflecting that petitioners had not filed medical records sufficient for respondent to assess the case and
objecting to the use of a short form petition, as both objections were commonly made in the OAP cases
filed pursuant to Vaccine General Order #1. See Poling ECF No. 5. This assumption is borne out by the
Order Deferring Ruling on Petitioners' Motion for Complete Transparency of Proceedings. Poling, 2008
WL 1883059, at *11-12.

                                                      24
                 b. Motions Regarding Dr. Zimmerman.

        Leaving the issue of violations of § 12(d)(4)(A) aside temporarily, there are other
issues surrounding the use of Dr. Zimmerman’s report that are bound up with
petitioners’ requests to depose him or compel his appearance at the hearing in their
son’s case.

        Petitioners first requested disclosure of Dr. Zimmerman’s expert report in Poling
in their reply to respondent’s objection to petitioners’ motion for relief from my decision
dismissing their claim.59 See ECF No. 104 at 4, n.1. They apparently believed that Dr.
Zimmerman had filed a report that had affected respondent’s decision to concede the
Poling case, and argued that because Poling was “designated” as a test case, the
waiver of the privacy provisions filed by petitioners in each of the actual test cases
somehow applied to the Poling case as well.

        Based on the OAP docket (http://www.cofc.uscourts.gov/docket-omnibus-autism-
proceeding), as well as the docket in Poling, No. 02-1466, petitioners’ assertions are
factually incorrect. The Poling case was never formally designated as a test case,
(Poling, 2008 WL 1883059, at *1-2), and the petitioners in that case consequently never
filed that express written consent.60

      Given the procedural posture of this case at the time, I did not rule on petitioners’
request, expecting that petitioners would retain experts and file their reports pursuant to
my orders, likely obviating the need to decide whether production of the expert report
was within my authority and necessary to a fair and just resolution of the issues.

        Apparently unsatisfied by the experts they had obtained, on March 31, 2013,
petitioners moved for leave to serve a subpoena on Dr. Zimmerman. Petitioners’
Motion for Leave to Serve a Deposition Subpoena or Other Appropriate Relief, Including
Disclosure of Relevant Evidence [hereinafter “Pet. Mot. for Subpoena”], filed Mar. 31,
59They also requested disclosure of the other expert reports filed in Poling, asserting that, as these
expert reports were filed while the Poling case was under consideration as a test case, they should be as
publically available as the reports in other test cases. Again, with reference to the public docket in Poling,
No. 02-1466, there is no indication that any expert reports were filed in Poling prior to the government’s
concession in the November 2007 Rule 4 report. Pet. Ex. 57, the Rule 4 Report in Poling, does not
reference any expert reports, referring only to the treatment and diagnostic records.
60  The Poling case does appear on the “List of Potential Test Cases for May 2008 Hearings,” the hearings
in the Theory 2 test case as one of three cases being considered for test case designation. See Autism
Master File, OAP docket, filing of Sep. 17, 2007, at 3. See http://www.cofc.uscourts.gov/docket-omnibus-
autism-proceeding. The filing contained the disclaimer: “By filing these records and designating these
claims as ‘potential test cases,” neither claimant nor the PSC represent that any one petition will actually
be designated for hearing in the May 2008 general causation proceedings.” Id. at 1; see
http://www.cofc.uscourts.gov/docket-omnibus-autism-proceeding. Once again, petitioners in the instant
case either misconstrued or misstated what had occurred. I note that A.K.’s own case, which did not
appear on the list of “potential test cases,” was designated as a test case on January 8, 2008, via the
filing of an expert report in the [R.K, on behalf of A.K.] case in the OAP docket on that date. “PSC's Expert
Report in [R.K, on behalf of A.K.] Test Case” at 1; see http://www.cofc.uscourts.gov/docket-omnibus-
autism-proceeding. The report was removed from the OAP docket when petitioners in [R.K, on behalf of
A.K.] withdrew as a test case.
                                                      25
 2013 (ECF No. 216). On close examination, the subpoena request was a thinly veiled
 attempt to compel Dr. Zimmerman to give expert testimony in this case, rather than
 testify as a percipient witness, treating physician, or retained expert. Later, petitioners
 conceded that they had contacted Dr. Zimmerman “and were informed that he would
 not testify as an expert except in cases in which he was the treating physician.” ECF
 309 at 7-8 (Petitioners’ Reply Brief in support of their motions to reopen the record and
 judicial estoppel). Petitioners’ many filings on the Zimmerman subpoena issue are rife
 with misstatements or misunderstandings of the matters asserted. The facts (and their
 assertions) overlap to some extent with those in the estoppel motions. I thus address
 the background matters pertinent to both motions here.

                   c. Additional Background Information and Facts.

        Petitioners claim that they only learned of Dr. Zimmerman’s report in Poling on
 March 30, 2013. ECF No. 216 at 1. This assertion is rebutted by their own earlier filing
 of November 6, 2010 (ECF No. 104), which reflected that they were aware of such an
 expert report filing long before March 2013. Id. at 4, n.1. See n.54 supra.

         Petitioners’ claim that the Poling case involved a concession of causation based
 on Dr. Zimmerman’s report in Poling (ECF No. 216 at 3-4) is raised in several filings.
 See, e.g., ECF No. 227 at 5, n.5 (referencing their request for Dr. Zimmerman’s report
 in ECF No. 216); ECF No. 227 at 15 (asserting that the Zimmerman’s report in Poling
 was a decisive factor in the decision to settle).61 The timeline and records in Poling
 reflect otherwise.

         On November 9, 2007, respondent conceded petitioners’ entitlement to
 compensation in Poling in her Rule 4 report. Poling ECF No. 17; Pet. Ex. 57. Five days
 later, the presiding special master ordered a status conference “to discuss further
 proceedings to address damages.” Poling ECF No. 18. Doctor Zimmerman’s report
 was filed on December 13, 2007, more than a month after respondent’s Rule 4 report
 was filed. Poling ECF No. 24. Thus, the temporal relationship alone belies petitioners’
 assertions that Dr. Zimmerman’s expert report resulted in the concession.62

 61This description may not be entirely inaccurate. Doctor Zimmerman’s report may have played a role in
 the amount of compensation petitioners in Poling ultimately received, because the first substantive Rule 4
 report in Poling denied that the Poling child’s seizure disorder was related to the encephalopathy for
 which entitlement was conceded. The special master’s fees and costs decision reflected that the Poling
 petitioners were compensated for the seizure disorder as well as the other injuries that were conceded in
 the Rule 4 report. Poling, 2011 WL 678559, at *1.
 62As one of the Poling child’s treating physicians, it is possible and even likely, that opinions on
 connection or causation by Dr. Zimmerman were expressed in the child’s medical records. These do not
 constitute “expert reports,” and in any event such documents are not publically available, absent express
 written consent of the petitioners in the Poling case.

        Given that respondent’s amended Rule 4 report, filed on February 21, 2008
(Poling, No. 02-1466, ECF No. 27), has never been publically disclosed, the best
evidence of why respondent conceded entitlement to compensation would be found in
the special master’s decisions in that case. However, neither the special master’s order
to proceed to a damages determination (Poling, No. 02-1466, ECF No. 35) (which is
not, strictly speaking a “decision” based on the use of that term in the Vaccine Act), nor
her decisions awarding damages (see Poling, No. 02-1466, ECF Nos. 115, 117, 120,
and 127) are publically available under the name “Poling.”63

         As the special master assigned to Poling explained in her April 10, 2008 Order,
Dr. Zimmerman’s report— [ * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * ] —was not filed
until after respondent’s initial Rule 4(c) report. Poling v. Sec’y, HHS, No. 02-1466V,
2008 WL 1883059, at *2 (Fed. Cl. Spec. Mstr. Apr. 10, 2008) (Order Deferring Ruling
on Petitioners’ Motion for Complete Transparency of Proceedings). Because the facts
demonstrate that Dr. Zimmerman’s report in Poling was filed after the case was
conceded in the Rule 4 report, it could not possibly have been a factor in respondent’s
decision to concede entitlement to compensation on the basis of a Table injury.

       The unredacted attorney fees and costs decision filed on January 28, 2011, (see
Poling, 2011 WL 678559) answers the question of why the Poling case was conceded.
There, the special master clearly and unequivocally noted that the concession was
based on the presence of a Table encephalopathy. When a prima facie case for a
Table encephalopathy exists, causation is presumed. See 42 C.F.R. § 100.3; de
Bazan, v. Sec'y, HHS, 539 F.3d 1347, 1354 (Fed. Cir. 2008) (citing Knudsen v. Sec'y,
HHS, 35 F.3d 543, 548 (Fed.Cir.1994). Such a presumption may not be rebutted by the
presence of an “idiopathic, unexplained, unknown, hypothetical, or undocumentable
cause, factor, injury illness, or condition.” §13(a)(2). The cause of most cases of ASD

63A redacted damages decision, CHILD DOE/77 v. Sec’y, HHS, 2010 WL 3395654 (Fed. Cl. Spec. Mstr.
Aug. 27, 2010), was issued the same date that a redacted damages decision entry appears in the docket
of the Poling case (Poling ECF No. 127). A perusal of the redacted decision suggests that these two
cases are one and the same. However, I do not rely on the redacted CHILD DOE/77 decision to
determine why respondent conceded the Poling case, if, indeed, they are the same case.

                                                    27
is unknown, although genetic factors and prenatal influences are strongly suspected.
Dwyer, 2010 WL 892250, at *29-36; Snyder, 2009 WL 332044, at *46-53. Thus, a “she
has ASD” defense would not suffice to demonstrate alternate causation.

       I find that the Zimmerman expert report was not what prompted the respondent
to concede the Poling case. I find, consistent with the presiding special master’s
published decision, that the Poling case was conceded based on the presence of a
Table encephalopathy.

                d. Issues Related to Concession, Conspiracy, and Concealment.

       In numerous filings, petitioners have obstinately insisted that respondent, her
agents, or other governmental officials have conceded the causation theory they have
advanced.64 They claimed that respondent deliberately conceded the Poling case to
avoid having a special master rule on the issues presented, and thereafter concealed
what had happened in Poling. These issues all feed into the judicial estoppel
arguments.

        Petitioners first asserted that respondent had, in effect, conceded their theory of
causation in October of 2010, when they filed their Motion for Reconsideration and
Relief from Order and Decision Dismissing Petition (ECF No. 100). In support of their
argument that I restore their petition, petitioners provided a quotation65 from Dr. Julie
Gerberding, former Director of the Center for Disease Control, and stated that “[t]hus,
mitochondrial dysfunction can generate autism-like symptoms.” Motion for
Reconsideration (ECF No. 100) at 14.

        In their subsequent Reply, filed November 6, 2010, petitioners took their
admission argument a step further. They argued that “[t]he Rule 4 Report filed in Poling
is a pleading in a prior proceeding and constitutes an admission that…a vaccination of a
person with [a mitochondrial disorder] can cause symptoms similar to those evidencing
autism.” Petitioners’ Reply to respondent’s Response to Motion to Reconsider, filed
November 6, 2010, at 6 (ECF No. 104).

      For the past five years, petitioners have repeatedly insisted that the government
conceded the Poling petitioners’ theory of causation and is thus unable to contest their
64 Petitioners are not always consistent about the causation theory they claim was “conceded.” See, e.g.,
Reply to Response to Motion for Reconsideration, filed Nov. 6, 2010, at 6 (ECF No. 104) (stating that the
Poling Rule 4 report was an admission that vaccination of a person with a mitochondrial disorder can lead
to symptoms of autism); Motion to Amend Schedule and Award Interim Cost of Expert Witness, filed Nov.
30, 2010, at 3 (ECF No. 109) (stating that the government had conceded a “mitochondrial
encephalopathy”).
65Doctor Gerberding’s comments about the Poling case were prefaced by her statement: “I don’t have all
the facts because I still haven’t been able to review the case files myself.” Pet. Ex. 37 at 3. I note that
she is a doctor, not a lawyer and, while she may have general medical knowledge about decompensation
and regression in mitochondrial disorders, there is no evidence of her medical specialty. Saying that
respondent is bound by an uninformed comment by a subordinate official is absurd. Holt, 2015 WL
4381588, at *29 n.80.

                                                     28
entitlement to compensation. Their arguments generally fell into six categories. First,
they claimed that respondent has conceded the theory of causation in a party
admission. See, e.g., Motion for Reconsideration (ECF No. 100), Reply (ECF 104),
Petitioners’ Motions in Limine, filed Apr. 8, 2013 (ECF No. 227), Prehearing
Submissions, filed Apr. 8, 2013 (ECF No. 228), Motion for Leave to File Exhibits, filed
Jun. 17, 2014 (ECF No. 303). Second, they insinuated that respondent purposefully
avoided an adverse ruling in Poling by removing it from the OAP and attempting to
prevent the disclosure of any facts to the public, implying that respondent’s actions were
in some way underhanded. See, e.g., Motion to Issue Subpoena, filed Mar. 31, 2013
(ECF No. 216), Motions in Limine (ECF No. 227), Reply to Motions in Limine, filed May
20, 2013 (ECF No. 259), Supplemental Motion for Leave to File Exhibits, filed Jun. 26,
2014 (ECF No. 306).66 This argument, which is completely unfounded, entirely
mistakes the progression of events surrounding the Poling case.67 Their third argument
was that courts have already accepted their causation theory. See, e.g., Motions in
Limine (ECF No. 227), Post-Hearing Brief, filed May 5, 2014 (ECF No. 297), Motion for
Leave to File Exhibits (ECF No. 303), Supplemental Motion for Leave to File Exhibits
(ECF No. 306). Fourth, they argued that Dr. Zimmerman’s expert report from the Poling
case directly led to that case’s concession.68 See, e.g., Motion to Amend Schedule,
filed Nov. 30, 2010 (ECF No. 109), Motions in Limine (ECF No. 227), Supplemental
Motion for Leave to File Exhibits (ECF No. 306). Fifth, they insisted that it is
fundamentally unfair for the government to be allowed to take an inconsistent position in
this case, given their concession of Poling. See, e.g., Motions in Limine (ECF No. 227),

66In this filing, petitioners asserted that the government may have suppressed information regarding
vaccine safety. ECF 309 at 9.
67 Petitioners in Poling filed a “Motion for Complete Transparency of Proceedings” on March 4, 2008. On
April 10, 2008, then-Special Master Campbell Smith issued a published Order Deferring Ruling on
Petitioners’ Motion for Complete Transparency of Proceedings, No. 02-1466V, 2008 WL 1883059 (Fed. Cl.
Spec. Mstr. Apr. 10, 2008). Special Master Campbell-Smith provided an exhaustive history of the
matter and ultimately concluded that any public disclosure of case materials, including the Rule 4
Reports, would, under § 12(d)(4)(A) of the Vaccine Act, require the consent of the parties. When she
issued her Order, the parties had “been unable to execute a signed consent form.” Id. at *11. She
encouraged the parties to execute such a form given their “expressed willingness” to do so and provided
the parties with 60 days within which to come to an agreement. Id. Apparently, the parties never
managed to resolve the issue, as the Poling docket indicates that more than a year later, Special Master
Campbell-Smith ordered petitioners to file a motion withdrawing their motion for complete transparency by
July 22, 2009 (ECF No. 85). On July 20, 2009, petitioners filed a “Motion to Withdraw Previously Filed
Motion” (ECF No. 86), which presumably was the motion for complete transparency. Special Master
Campbell-Smith’s Order and the publically available Poling docket entries make clear that both
respondent and petitioners were interested in complete public disclosure of all of the facts and records
related to the Poling case. Had the parties managed to execute a signed consent agreement in
accordance with § 12(d)(4)(A) of the Vaccine Act, petitioners’ motion likely would have been granted.
Contrary to petitioners’ claims in the instant case, respondent did not purposefully prevent the public
disclosure of the Poling Rule 4 Reports. (It is worth noting that Rule 4 Reports are customarily never
publically disclosed, so respondent’s willingness to disclose the Poling Rule 4 Reports, contingent upon
petitioners’ permission, was rather extraordinary. If anything, this indicates that respondent was very
interested in the public dissemination of the Poling case materials.)
68Respondent contested petitioners’ statement that Poling was settled in part because of the expert
reports. In her Response, respondent stated that compensation in that case was not based on expert
reports. Respondent’s Response, filed Dec. 14, 2010 (ECF No. 113), at 2, n.1.

                                                    29
Reply to Motions in Limine (ECF No. 259), Motion for Leave to File Exhibits (ECF No.
303), Supplemental Motion for Leave to File Exhibits (ECF No. 306). And finally, they
argued that the government has a duty to the public to provide evidence in support of
petitioners’ theories. See, e.g., Motion to Issue Subpoena, filed Mar. 31, 2013 (ECF No.
216), Supplemental Motion for Leave to File Exhibits (ECF No. 306), Reply to Response
to Supplemental Motion for Leave to File Exhibits, filed Jul. 14, 2014 (ECF No. 309).

       Petitioners in the instant case asserted that Dr. Zimmerman’s testimony would
support the medical theory that they advanced and sought to compel his expert opinion.
See generally Pet. Mot. for Subpoena (ECF No. 216). Petitioners did not cite any legal
authority that would empower me to compel an expert witness to provide an opinion, nor
did they assert that Dr. Zimmerman had ever met, let alone treated, A.K.

        Respondent filed her response on April 8, 2013. She correctly noted that the
Vaccine Act does not provide petitioners a right to discovery (see Response at 1-2 (ECF
No. 224); see also 42 U.S.C. § 300aa-12(d)(3)(B)), and, further, that petitioners did not
demonstrate how subpoenaing Dr. Zimmerman would lead to any information relevant
to their case. See Response at 3-4.

       4. Legal Standards and Analysis.

              a. Standard for Compelling Discovery and Expert Witness Testimony.

       Under the rules for civil procedure governing litigation in the Court of Federal
Claims and other federal courts, a judge may authorize a subpoena to an expert
witness. However, this authority is rarely invoked or granted. See Resource
Investments, Inc. v. U.S. [Resource II], 93 Fed. Cl 373, 378 (2010). “[A]lthough it is not
the usual practice, a court does have the power to subpoena an expert witness and,
though it cannot require him to conduct any examinations or experiments to prepare
himself for trial, it can require him to state whatever opinions he may have previously
formed.” Carter-Wallace, Inc. v. Otte, 474 F.2d 529, 536 (2d. Cir. 1972). See also
Kaufman v. Edelstein, 539 F.2d 811 (2d. Cir. 1976) (an antitrust case determining that
an expert may be called against his will if “[a] substantial part of the testimony which the
Government…seeks…is testimony no one else can give.”).

       These rules do not govern discovery in Vaccine Act proceedings, but the cases
interpreting them may be helpful in understanding why such subpoenas are limited to
unusual factual situations. The Vaccine Act provides that rules for proceedings under
the Act shall “provide for limitations on discovery and allow the special masters to
replace the usual rules of discovery in civil actions in the United States Court of Federal
Claims.” §12(d)(2)(E). They further provide the presiding special master the authority
to “require such evidence as may be reasonable and necessary” and to “require the
testimony of any person and the production of any documents as may be reasonable
and necessary.” § 12(d)(3)(B)(i) and (iii).

       Courts have, on occasion, subpoenaed an expert witness who already has

                                             30
critical information about a pending case. But if an expert is not willing to opine and is
not already familiar with the case, courts have held that he should not be subpoenaed.
See, e.g., Buchanan v. Am. Motors Corp., 697 F.2d 151 (6th Cir. 1983) (holding that the
district court did not err in quashing a subpoena for an expert witness who was a
stranger to the litigation). Courts are generally discouraged from subpoenaing expert
witnesses. See, e.g., Fed. R. Evid. 706 (stating that although a court may appoint an
expert witness, it “may only appoint someone who consents to act.”). As Judge Block
has noted, “expert testimony is ordinarily a matter of private contract and may not be
compelled.” Resource II, 93 Fed. Cl. at 378. An expert witness “is ordinarily not the
proper subject of a subpoena.” Id. at 383.

       Parties to a case authorized by the Vaccine Act are not entitled to formal
discovery; informal exchanges of relevant information are preferred. Rule 7(a). Should
a party determine that informal discovery is inadequate, “the party may move the
special master…to employ any of the discovery procedures set forth in RCFC 26-37.”
Rule 7(b)(1). Any such motion must include “the discovery sought and state with
particularity the reasons therefor, including an explanation as to why informal discovery
techniques have not been sufficient.” Rule 7(b)(2). Upon a party’s request, a “special
master may approve the issuance of a subpoena pursuant to RCFC 45.” Rule 7(c)
(emphasis added).

       Court of Federal Claims Rule 45 explains the procedures required for the
issuance of a subpoena, but notes that the court may quash a subpoena if it requires
“disclosing an unretained expert’s opinion or information that does not describe specific
occurrences in dispute and results from the expert’s study that was not requested by a
party.” RCFC 45(d)(3)(B). Notwithstanding a judicial officer’s discretion to quash or
modify a subpoena in such circumstances, the court may elect to order appearance or
production if two criteria are met: (1) the serving party “shows a substantial need for the
testimony or material that cannot be otherwise met without undue hardship;” and (2) the
serving party “ensures that the subpoenaed person will be reasonably compensated.”
RCFC 45(d)(3)(C).

              b. Application to This Case.

        Although a court may, when circumstances warrant, compel an expert to provide
testimony, this is a significant departure from the general rule that an expert witness
should not be compelled to testify. See Resource II, 93 Fed. Cl. at 378. Courts are
reluctant to subpoena expert witnesses unless they already have critical information
related to the case at bar. See Buchanan, 697 F.2d 151. Absent extraordinary
circumstances, it is inappropriate to approve a subpoena for an expert witness who is
not willing to opine.

       Under RCFC 45(d)(3)(B), I may quash a subpoena that would require the
disclosure of “an unretained expert’s opinion…that does not describe specific
occurrences in dispute and results from the expert’s study that was not requested by a
party.” Doctor Zimmerman’s report in the Poling case does not describe “specific

                                             31
occurrences in dispute” in the instant case. [ * * * * * * * * * * * * * * * * * * * * * * * * *
******************************************************
******************************************************
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * ] Moreover, as Dr. Zimmerman
has never treated A.K., he has no familiarity whatsoever with the case at bar. And,
as petitioners’ own expert conceded at trial (Tr. 368-71), the facts of A.K.’s case bear
no resemblance to those in the Poling case. Thus, RCFC 45(d)(3)(B)
overwhelmingly favors denying petitioners’ request for a subpoena for Dr.
Zimmerman.

       5. Denying Subpoena.

       Although a subpoena for expert testimony may be appropriate in some
extraordinary circumstances, they do not exist here, where Dr. Zimmerman has never
treated A.K. and has declined to offer an expert opinion. RCFC 45(d)(3)(C) empowers
me to, in my discretion, order the testimony of a witness if petitioners have a
“substantial need for the testimony” that they could not otherwise obtain “without due
hardship” and petitioners ensure that the witness will be “reasonably compensated.”
Petitioners have made no such showing.

        Furthermore, I do not find such action to be reasonable and necessary to a fair
and just resolution in this case. Petitioners produced a qualified expert (Dr. Fran
Kendall) who opined that vaccines can trigger or aggravate an underlying mitochondrial
disorder. Even if Dr. Zimmerman’s testimony would buttress that of Dr. Kendall (and,
his willingness to testify only in cases in which he has been a treating physician
suggests that his opinions are narrower and more nuanced than petitioners claim), it is
not reasonable or necessary in this case.

      In my discretion, I find that petitioners have not demonstrated a need for Dr.
Zimmerman’s testimony about an unrelated case alleging a somewhat similar injury
caused by different vaccinations. Their motion for a subpoena is DENIED.

       6. Judicial Estoppel.

               a. Background of the Motions.

       Petitioners requested that I issue an order either compelling respondent “to admit
that a vaccine can cause significant aggravation of a pre-existing mitochondrial disorder
which may can manifest[ ] as an encephalopathy with features of autistic spectrum
disorder,” or to bar, “on the grounds of estoppel, respondent from denying that a
vaccine can cause significant aggravation of a pre-existing mitochondrial disorder.”
Motions in Limine at 20 (ECF No. 227).

        Respondent filed her Response [hereinafter “Response to Motions in Limine”] to
petitioners’ motion for judicial estoppel on May 13, 2013. Respondent argued that
petitioners’ request was barred as a matter of law. Response to Motions in Limine at 1-
2 (ECF No. 258). Additionally, respondent asserted that she never conceded that a

                                                32
vaccine was capable of significantly aggravating a pre-existing mitochondrial disorder
and, moreover, that the instant case differed from Poling in “many critical ways,”
including the vaccine in question and the presence or absence of a Table injury.
Response to Motions in Limine at 2-3 (ECF No. 258).

       On May 20, 2013, petitioners filed a Reply to Respondent’s Response to their
Motions in Limine [hereinafter “Pet. Reply”] in which they argued that respondent had
“profoundly mischaracterize[d]” their motion for judicial estoppel (Pet. Reply at 1 (ECF
No. 259)), focusing on collateral estoppel rather than judicial estoppel (id. at 5).
Petitioners described the Rule 4(c) report respondent filed in Poling as “an admission by
respondent in a pleading that vaccinations can aggravate an underlying mitochondrial
disorder.” Id. at 3. Since they contend that their case was substituted for Poling as a
test case once Poling was withdrawn from the OAP, petitioners argue that the Rule 4(c)
report filed by respondent in Poling is binding on respondent in their case. Id. at 4.
There is no evidence that this assertion is correct. Petitioners also argue that the
doctrine of collateral estoppel is inapplicable here because petitioners were parties to
the OAP at the time the Poling report was filed. Id. at 5. Nevertheless, petitioners
argue, respondent should be unable to “relitigate an issue resolved within the Omnibus
Cases as it applies to a former omnibus participant,” id. at 7, and essentially seek to
invoke collateral estoppel against respondent as an alternative theory.

       Petitioners renewed their motion in their post hearing brief69 and again on June
17, 2014. See Motion to Renew Petitioners’ Motion to Compel Respondent’s Admission
of the Medical Theory Upon Which Petitioners Rely, filed Jun. 17, 2014 (ECF No. 303).
Respondent reiterated her objections to the invocation of estoppel. See Respondent’s
Response to Petitioners’ Motions, filed Jul. 7, 2014 (ECF No. 308). The matter has
remained pending.

                  b. Legal Standards and Analysis.

                           (1) Estoppel.

       Estoppel is a common law doctrine that sometimes functions to prevent a party in
one lawsuit from taking a contrary position or relitigating issues in a subsequent lawsuit.
There are two discrete forms of estoppel—judicial and collateral. Judicial estoppel is
used to prevent a party from making an argument in a legal proceeding that is
inconsistent with an argument that same party took in a previous proceeding. New
Hampshire v. Maine, 532 U.S. 742, 749 (2001); see also Pegram v. Herdrich, 530 U.S.
211, 277, n.8 (2000). Under the doctrine of judicial estoppel, “where a party assumes a
certain position in a legal proceeding, and succeeds in maintaining that position, he may
not thereafter, simply because his interests have changed, assume a contrary position,
especially if it be to the prejudice of the party who has acquiesced in the position
formerly taken by him.” Davis v. Wakelee, 156 U.S. 680, 689 (1895). In essence, a
party to litigation may not use an inconsistent position to seek an advantage when doing
so would require the party to rely upon an incompatible theory. Judicial estoppel

69   See Pet. Post-Hearing Memo, filed May 5, 2014, at 115-117 (ECF 297).

                                                    33
protects the integrity of the judicial process by “prohibiting parties from deliberately
changing positions according to the exigencies of the moment.” New Hampshire, 532
U.S. at 750 (internal citation omitted). “Because the rule is intended to prevent improper
use of judicial machinery, judicial estoppel is an equitable doctrine invoked by a court at
its discretion.” Id.

       As a threshold matter, judicial estoppel requires a final decision on the merits. It
therefore does not apply if a party settled the claim in which it allegedly held a contrary
or inconsistent position. Moreland Corp. v. United States, 76 Fed. Cl. 268, 294 (2007);
see also Vernacchio, 2015 WL 1396357, at *5. Assuming that this basic requirement is
met, courts then consider whether the invocation of judicial estoppel is appropriate.

        In order to use the doctrine of judicial estoppel against an opposing party, a
litigant must first satisfy three requirements. First, courts determine whether one party’s
position is “clearly inconsistent” with its previous position. Second, courts consider
whether a party’s later inconsistent position could pose a threat to judicial integrity.
(Courts avoid accepting inconsistent positions in a later proceeding if doing so would
“create the perception that either the first or the second court was misled.” Moreland,
76 Fed. Cl. at 294 (quoting Cuyahoga Metropolitan Housing Authority v. U.S., 65 Fed.
Cl. 534, 556 (2005)). Third, courts consider “whether the party seeking to assert an
inconsistent position would derive an unfair advantage or impose an unfair detriment on
the opposing party if not estopped.” Id.

        Collateral estoppel, also known as issue preclusion, prevents a party from
relitigating an issue that has already been decided. The doctrine provides that “a
judgment on the merits in the first suit precludes relitigation in a second suit of issues
actually litigated and determined in the first suit.” Innovad Inc. v. Microsoft Corp., 260
F.3d 1326, 1334 (Fed. Cir. 2001). Essentially, if a court has “decided an issue of fact or
law necessary to its judgment, that decision may preclude relitigation of the issue in a
suit on a different cause of action involving a party to the first case.” San Remo Hotel,
L.P. v. City and County of San Francisco, Cal., 545 U.S. 323, 336 n.16 (2005) (quoting
Allen v. McCurry, 499 U.S. 90, 95 (1980)). As with judicial estoppel, in order to invoke
collateral estoppel, a court must have issued a final decision on the merits of a case.

        Although there are several ways a party can use collateral estoppel, the one
most relevant to petitioners’ argument is offensive non-mutual collateral estoppel,
whereby a new plaintiff in a later lawsuit attempts to assert a final judgment on a
particular issue against the defendant from an earlier lawsuit. In such cases, courts
employ the Parklane Hosiery test to determine whether the invocation of collateral
estoppel is appropriate. Courts ask if the party trying to assert collateral estoppel could
have intervened in the earlier suit; whether the defendant had incentive to litigate the
first action; whether there are multiple prior inconsistent judgments; and whether there
are any procedural opportunities available to the defendant in the second suit that were
unavailable in the first suit. Parklane Hosiery Co., Inc. v. Shore, 439 U.S. 322 (1979).
Very importantly, the doctrine of offensive non-mutual collateral estoppel generally does
not apply to the federal government. United States v. Mendoza, 464 U.S. 154 (1984).

                                             34
                         (2) Inapplicability of Collateral Estoppel to the Vaccine Program.

         Collateral estoppel is never appropriate in Vaccine Act cases. In Mendoza, the
Supreme Court held that non-mutual offensive collateral estoppel cannot be applied
against the federal government. Mendoza, 464 U.S. at 160. The United States is
inherently different than a private litigant due to the geographic scope and multiplicity of
its litigation. Id. Furthermore, government litigation frequently addresses legal
questions of substantial importance, and therefore allowing the United States to be
subject to estoppel would “thwart the development of important questions of law.” Id.

       The bar on the application of collateral estoppel against the United States
includes Vaccine Program cases, despite petitioners’ policy arguments to the contrary.
Under Section 12(b)(1) of the Act, the Secretary of the Department of Health and
Human Services, a federal entity, is officially designated to defend against a petitioner’s
claim. 42 U.S.C. § 300aa-12(b)(1). Numerous vaccine cases have affirmed the
inapplicability of the collateral estoppel doctrine in this context. See, e.g., Bast v. Sec’y,
HHS, 117 Fed. Cl. 104, 124 n. 18, appeal dismissed sub nom., M.S.B. ex rel. Bast v.
Sec’y, HHS, 579 F. App’x 1001 (Fed. Cir. 2014); Stewart v. Sec’y, HHS, No. 06-777V,
2011 WL 2680580, at *2 (Fed. Cl. Spec. Mstr. June 15, 2011); Sharkey v. Sec’y, HHS,
No. 99-669V, 2010 WL 5507915, at *1 (Fed. Cl. Spec. Mstr. Dec. 10, 2010).

        While there are some exceptions to the bar against collaterally estopping the
federal government,70 petitioners are unable to demonstrate that such circumstances
exist in their case. Claims authorized by the Vaccine Act are very fact-specific. “A
special master’s acceptance of a theory in one case does not require him or her to
accept the theory in subsequent cases involving similar facts or the same vaccine.
Rather, a different evidentiary record can lead to different outcomes.” Rickett v. Sec’y,
HHS, 468 Fed. Appx. 952, 959 (Fed. Cir. 2011). Given the varied nature of Vaccine Act
cases, and the ever-evolving medical and scientific evidence that informs their
resolution, collateral estoppel can never be appropriate. To determine otherwise would
“thwart the development of important questions of law by freezing the first final
decision.” Mendoza, 464 U.S. at 160. Thus, petitioners are unable to use the doctrine
of non-mutual offensive collateral estoppel against respondent in this case.

                         (3) Inapplicability of Judicial Estoppel to this Case.

      Although it is abundantly clear that petitioners cannot invoke collateral estoppel
against respondent in this or any other case, I am unaware of any similar bar against
the application of judicial estoppel in Vaccine Act cases. See Vernacchio, 2015 WL

70For instance, the bar may not apply where the public policy considerations that favor suspension of
collateral estoppel are not present. See, e.g., N.L.R.B. v. Donna-Lee Sportswear Co., Inc., 836 F.2d 31
(1st Cir. 1987) (holding that the private interest of the parties predominates so the public policy
considerations were not valid). Similarly, the doctrine has been applied against the United States where it
was only a nominal party with no demonstrated direct interest in the subject matter of the suit. Westerchil
Const. Co., Inc. v. United States, 16 Cl. Ct. 727, 732-33 (1989).

                                                     35
1396357, at *5) (remarking that petitioners’ judicial “estoppel argument does not appear
to have been advanced in any Vaccine Program cases before.”). Nevertheless, for
reasons explained below, petitioners’ motion for judicial estoppel fails.

        However, there are at least four reasons against applying judicial estoppel
against respondent in this case. First, and most importantly, judicial estoppel does not
apply when a claim has been settled. Petitioners seek to treat the statements contained
in respondent’s Poling Rule 4(c) report as a global concession (with respect to all
subsequent cases involving alleged preexisting mitochondrial disorders) of the first
prong of Althen. But petitioners have somehow missed an essential fact. Poling was
settled, not adjudicated, and “judicial estoppel does not apply where a party settles the
claim in which it is alleged to have made an inconsistent statement.” Moreland, 76 Fed.
Cl. at 295; see also United States v. International Bldg. Co., 345 U.S. 502, 506 (1953)
(holding that a settlement is not an adjudication on the merits and that applying judicial
estoppel in such a case “would serve an unjust cause: it would become a device by
which a decision not shown to be on the merits would forever foreclose inquiry into the
merits.”).

       Second, petitioners have failed to satisfy the three requirements for the
invocation of judicial estoppel. Respondent’s position in this case is not “clearly
inconsistent” with her position in Poling. In Poling, respondent’s position was that the
child had sustained a Table injury within the timeframe established for both the MMR
and DTaP vaccinations, and thus presumptively should be compensated. Here, there is
no allegation that A.K. suffered a Table injury within the requisite time period. I also
note that the allegedly causal vaccine, influenza, was not associated with a Table
injury—nor was it even on the Vaccine Injury Table as a vaccine covered by the
Program—at the time that this claim was filed. Lacking an inconsistent position, there
can be no threat to judicial integrity.

       Allowing respondent to argue against entitlement to compensation in A.K.’s case
in no way “create[s] the perception that either the first or the second court was misled.”
Moreland, 76 Fed. Cl. at 294 (quoting Cuyahoga, 65 Fed. Cl. 556). Moreover,
respondent derives no unfair advantage and imposes no unfair detriment on the
opposing party if not estopped. Id. Indeed, declining to apply judicial estoppel against
respondent in this case imposes no additional burden on petitioners; in order to
establish entitlement to compensation, they must either demonstrate that A.K. suffered
a Table injury or provide preponderant evidence that A.K.’s influenza vaccinations
actually caused his condition, using the framework established by Althen and its
progeny. Petitioners here are in precisely the same situation as all other Vaccine Act
claimants. Declining to provide them with special treatment does not constitute an
unfair burden.

      Third, decisions issued by special masters and judges of the Court of Federal
Claims constitute persuasive, not binding, authority. Guillory v. Sec’y, HHS, 59 Fed. Cl.
121, 124 (2003), aff’d, 104 F. App’x 712 (Fed. Cir. 2004); Hanlon v. Sec’y, HHS, 40
Fed. Cl. 625, 630 (1998), aff’d, 191 F.3d 13444 (Fed. Cir. 1999). “Special masters are

                                            36
neither bound by their own decisions nor by cases from the Court of Federal Claims,
except, of course, in the same case on remand.” Id. at 630. This is especially true in
cases like these which involve different vaccines (in the instant case, one without any
associated Table injury), a different clinical presentation, and different timing. Thus,
even if the causation theories in two cases are identical, another special master’s
determination about a petitioner’s causation theory does not compel me to reach an
identical conclusion.

        Fourth and finally, a concession by respondent in one case does not constitute a
concession in another. Science and medicine are not immutable, and as the SCN1A
(Dravet syndrome) cases demonstrate,71 what was once viewed as a Table
encephalopathy is now known to be a genetic condition that cannot be compensated.
Evidence filed in one case may not be filed in another case. For example, a concession
that the measles vaccine can cause an encephalopathy occurring within 5 to 15 days of
a vaccination is not a concession that it can do so at times shorter or longer. Shyface v.
Sec’y, HHS, 165 F.3d 1344, 1351 (Fed. Cir. 1999) (quoting the legislative history of the
Vaccine Act asserting that a similarity to conditions or time periods in the Table would
not be sufficient to demonstrate vaccine causation). Thus, even if judicial estoppel
could be invoked against respondent based on the settling of the Poling case, it would
be impossible to do so here, where petitioners allege an entirely different vaccination
significantly aggravated their son’s condition.

                  c. Estoppel Motion Rejected.

        Neither judicial nor collateral estoppel is appropriate in this case, and so
petitioners cannot compel respondent to admit their causation theory. Collateral
estoppel can never be appropriate in Vaccine Act cases. Judicial estoppel on the basis
of the Poling Rule 4(c) Report is inappropriate because the Poling case was not
adjudicated, because petitioners failed to satisfy the three requirements for the
invocation of the doctrine, because the decision of one special master is not binding on
other special masters, and because the vaccines and injuries alleged in the two cases
in question are completely different. For these reasons, petitioners’ motion for
estoppel is DENIED.

          7. Motions Pertaining to Poling.

       Because respondent affirmatively used the Poling Rule 4 report, Pet. Ex. 57, in
this case, it is admitted. The admission of Dr. Zimmerman’s expert opinion letter is
addressed in subsection II., below.

71   See Barclay v. Sec’y, HHS, 122 Fed. Cl. 189 (2015).

                                                     37
C. Motions to File Exhibits Out of Time.

       1. Background.

         Prior to the entitlement hearing in this case, I set a deadline of March 22, 2013,
for the filing of medical literature. Order, issued Feb. 21, 2013 (ECF No. 199). In
conjunction with this prehearing order, I included letters for each expert identified as
testifying, stressing the importance of providing supporting medical literature to counsel
for filing prior to the entitlement hearing in this case. See attachments to Prehearing
order, ECF No. 199.

        On the day the medical literature was due, petitioners’ requested a four day
extension, indicating that they would be filling over 100 additional medical journal
articles. ECF No. 210. I granted their request, but warned them that I would not
consider additional literature filed after that date, absent a compelling reason. ECF No.
214. On March 26, 2013, petitioners filed over 100 medical journal articles. Less than
10% of these articles were actually discussed during the testimony or otherwise relied
upon at the hearing.

        On April 24, 2013, while the hearing was on-going, petitioners requested leave to
file Pet. Ex. 240, a recently published medical journal article. I granted their request.
This article was discussed extensively during the hearing. Four days later, petitioners
requested to file another newly published journal article, Pet. Ex. 241. I likewise granted
this request.

         Also during the hearing, petitioners provided copies of the slides that Dr. Deth
would be using to illustrate and supplement his testimony. See Pet. Exs. 239-40. The
slides referenced 25 medical journal articles that had not been filed in the case. I
therefore ordered petitioners to file all the journal articles thus referenced. When they
initially did so on May 31, 2013, they did not assign exhibit numbers to any of the
articles. Rather, they listed them by the slide number on which they appeared, referring
to page numbers of Pet. Ex. 239. I required petitioners to assign exhibit numbers to
each slide and to file an updated exhibit list. Order, issued Jun. 6, 2013 (ECF No. 270).
That exhibit list was filed on June 25, 2013 (ECF No. 271). Because the exhibits were
not re-filed, a chart reflecting the crosswalk between the articles and exhibit number is
set forth below.

        I allowed respondent’s expert, Dr. Johnson, to address petitioners’ late-filed
medical literature. Post-Hearing Order, issued Sept. 9, 2013 (ECF No. 278). Then, in
an effort to ensure that both parties had an adequate opportunity to perfect their cases, I
allowed petitioners until October 9, 2013 to make any additional evidentiary filings they
desired; and gave respondent until November 8, 2013 to do the same. I indicated my
intent to close the record at that point, after which I would set a deadline for post-
hearing briefs. Id. Both parties made substantial use of the opportunity for additional
evidentiary filings. On November 15, 2013, I informed the parties that the evidentiary
record in this case was complete and ordered them to file post hearing briefs. Post
Hearing Order, issued Nov. 15, 2013 (ECF No. 282).

       In various motions since, petitioners have requested that I admit additional
medical journal articles. Some have had only the most tenuous of relationships to the
matters presented at hearing. Others were available long before the record closed, but
were just “discovered” by petitioners. Most were cumulative of the matters addressed in
the volumes of medical literature already filed in this case, and only about 130 of the
approximately 280 medical journal or similar articles petitioners were filed were actually
mentioned in expert reports or discussed in testimony. Petitioners’ difficulty in keeping
track of exhibit numbers they have previously used contributes to the problems posed

                                                39
by their late filings.72 See, e.g., Motion for Leave to File Exhibit 240, filed Jan. 14, 2014
(ECF No. 284) (re-using an exhibit number and refiled on Jan. 16, 2014 as Pet. Ex.
270); Motion for Leave to File Exhibits 240,73 271, 272, 273, 274, 275, 276, 278, 280,
281, and 282, filed Jun. 17, 2014 (ECF No. 303); Supplemental Motion for Leave to File
Exhibit 277 and 279, filed Jun. 26, 2014 (ECF No. 306). Petitioners also skipped over
numbers 267 and 268, so their proposed exhibit numbers jump from 266 to 269.

      Many of the motions to admit this late filed medical literature have remained
pending. I rule on those motions now.

        2. Legal Standards and Analysis.

        When deciding whether new evidence justifies re-opening the record, special
masters have devised a four-factor test: “(1) the nature of the proffered new evidence;
(2) the prejudice to the parties; (3) the length of the delay; and (4) the reason for the
delay.” Vant Erve v. Sec’y, HHS, 39 Fed. Cl. 607, 612 (Fed. Cl. 1997), cited favorably
by Plavin v. Sec’y, HHS, 40 Fed. Cl. 609 (1998). Of these inquiries, the “paramount test
is the nature of the proffered new evidence.” Id. at 612. Special masters must consider
“the extent to which the new evidence is both relevant and affective of the outcome.” Id.
In instances where the proffered evidence “is of marginal relevance and impact,” the
moving party faces a significantly higher burden “with respect to the influence of the
remaining factors.” Id. at 612 (citing Horner v. Sec’y, HHS, 35 Fed. Cl. 23, 27 (1996)).
But the inverse is also true—if the proffered evidence is “highly relevant and clearly
outcome determinative…the importance of the remaining factors diminishes.” Plavin,
40 Fed. Cl. at 612 (citing Kaminski v. Sec’y, HHS, 39 Fed. Cl. 253 (1997).

         Petitioners have not persuaded me that most of their new evidence justifies re-
opening the record. First, the additional evidence is cumulative in nature; the record
already contains many articles about mitochondrial disorders and brain development,
oxidative stress, and various biochemical abnormalities seen in ASD. Second, given
the number of articles already filed addressing these same issues, they are in no way
prejudiced by my declining to re-open the record months after I declared it closed. And
finally, several of the proffered articles were published well before the record was
closed. Petitioners’ lack of diligence in researching and identifying articles in a timely
fashion is not a sufficient reason to accept these articles into the record. Petitioners
could have filed them into the record long before I announced that the record was
closed. Petitioners’ failure to file them in a timely manner does not constitute a
justification to re-open the record.

72This remarkable level of disorganization is not uncommon in Mr. McHugh’s office. See Rodriguez v.
Sec’y, HHS, No. 06-559V, 2009 WL 2568468, at *23 (Fed. Cl. Spec. Mstr. Jul. 27, 2009) (where I
deducted several hundred dollars from an attorney’s fees decision “based on Mr. McHugh’s poor
performance in preparing and filing the exhibits in this case.”)
73Apparently petitioners’ counsel forgot that he had redesignated the Rose article, which reused Pet. Ex.
240 (previously assigned to the Wong article), as Pet. Ex. 270.

                                                    40
           3. Granting in Part and Denying in Part Motions to File Late Exhibits.

        Given that I had to read each of the journal articles to see if they contained the
smoking gun for which petitioners have been searching, it is simpler at this point to
admit all of the proffered exhibits, with the exception of Pet. Ex. 277, which is addressed
separately below. This is in keeping with the approach taken to other evidentiary issues
in Vaccine Act cases. It is rare, for example, for a Daubert motion to be granted, even
though the special master may ultimately chose to reject an expert’s opinion entirely in
reaching a decision. Unfortunately, it rewards petitioners’ disregard of my orders, which
were designed to allow this case to be resolved as fairly and expeditiously as possible.
I also note that medical literature not discussed by an expert is often of little utility, even
to a special master well-versed in the subject matter of the article.

       I stress that none of these exhibits has had any impact on the causation decision
rendered in this case, but the time and effort required to apply the tests used to
determine whether they should be admitted would simply delay resolution of this case,
which has been pending for 12 years. As noted above, these late filed exhibits were
largely cumulative of other previously filed documents.74

        Petitioners’ Ex. 277 was discussed extensively in Section II.B, above (in
conjunction with the motions to subpoena Dr. Zimmerman and for application of judicial
estoppel to this case). This letter constitutes a matter submitted by a party in another
Vaccine Act case and, as such, it falls under the protection of § 12(d)(4)(A). As
petitioners have not also filed the express written consent of the party submitting it, I
cannot admit it into the record of this case. I will not consider it as substantive evidence
in this case. The portions of this ruling that discuss the substance of the letter will
be redacted from public view.

       Petitioners’ motions to file what had previously been identified as exhibits
238, 238A, 240, 241, 242, 243, 244, 245, 246, 247, 248, 249, 250, 251, 252, 253, 254,
255, 256, 257, 258, 259, 260, 261, 262, 263, 264, 265, 266, 269, 270, 271, 272, 273
274,75 275, 276, 278, 279, 280, 281, and 282 (chart filed June 16, 2014, at ECF No.
302), 274A (Funding Opportunity Announcement, filed June 17, 2014, at ECF No.
303),76 are GRANTED. Petitioners’ motion to file Pet. Ex. 277 is DENIED.

74In fact, most of the articles seem to relate to Dr. Deth’s presentation, which, as noted in the causation
decision, already cited many, many articles that were only tangentially related to his opinion. After
reviewing these late-filed articles, I concluded that petitioners’ flurry of late filings, relevant only at the
broadest levels, have not cured the core deficiencies in their experts’ theories.
75   Petitioners assigned exhibit number 274 to two exhibits. I designate the later-filed exhibit as “274A”.
 I note that respondent’s objections to the relevance of this document are well-founded. Resp.

Response to Petitioners’ Motions, filed July 7, 2014, at 1-4 (ECF No. 308).

                                                        41
D. Motion to Exclude OAP Evidence.

       1. Background.

       By filing their short-form petition in 2003, petitioners in this case joined the OAP.
See Section I(A), supra. After first agreeing to be a test case for Theory 2, they
withdrew in April of 2008, both as a test case and from the OAP. See Motion to
Withdraw Claim as a Test Case, April 10, 2008 (ECF No. 40). While a part of the OAP
and while still a test case, respondent filed medical literature pertaining to the use of
video evidence in autism diagnosis and research (Res. Exs. A, C-E); the timing and
nature of early autism symptoms recognized by parents (Res. Ex. B); and regression in
autism (Res. Ex. F). These articles were filed primarily due to a dispute between the
parties about my order to petitioners to file video footage of A.K., with respondent
asserting the validity of the use of videos in diagnosis of ASD.

        On February 25, 2008, also while this case was still designated as a test case,
respondent filed reports and CVs from her Theory 2 experts on general causation. See
Res. Exs. G-HH. (ECF No. 27). Two of the reports and accompanying CVs were later
withdrawn from the OAP Theory 2 cases, and from this case in particular, long after
petitioners had withdrawn as a Theory 2 test case. Of the remaining expert reports, two
involved experts who also testified in this case (Drs. Johnson and Jones) (Res. Exs. Q
and S, respectively. Another, Dr. Manuel Casanova, was the author of a medical
journal article that gave rise to Dr. Shafrir’s “triple hit” hypothesis. Still others, Drs.
Fombonne, Goodman, Lord, and Rutter, provided considerable information about
autism, regression in autism, and the epidemiology, matters highly relevant to
petitioners’ arguments about A.K.’s purported regression, the onset of his symptoms,
the clinical course of ASD, and whether there truly exists the “autism epidemic” about
which Dr. Shafrir testified in this case. The expert reports of Drs. Rodier and Kemper
addressed the prenatal origins of ASD, a matter highly relevant to evaluation of Dr.
Shafrir’s “triple hit” hypothesis, in which he asserted that events occurring in the second
or third year of life could be environmental triggers for regression and ASD. The report
of Dr. Rust, a pediatric neurologist and ASD specialist, on general causation was filed
on March 14, 2000, as Res. Ex. II. ECF No. 32. A case-specific expert report from Dr.
Rust was filed a few days later as Res. Ex. KK. ECF No. 35. Respondent’s Master List
of journal articles was filed on March 21, 2008, with the actual articles filed on a CD.
ECF No. 36.

       Petitioners filed expert their OAP Theory 2 expert reports on March 20, 2008,
including a report by Dr. Deth, one of their experts at the hearing in this case. ECF No.
34. Petitioners have never moved to withdraw these three reports, although they did
request to withdraw Dr. Mumper’s report, filed earlier, and I granted that request.

       In April 2008, petitioners withdrew as a test case, stating that they had decided
that A.K.’s case specific circumstances indicated that other causes might have
contributed to his ASD symptoms. However they noted that they might still rely to some
degree on the thimerosal causation theory: “By withdrawing his claim as a test case

                                             42
petitioner [sic] does not mean to imply any waiver whatsoever of the claim that TCVs
contributed to his autistic symptoms; instead, petitioner [sic] withdraws his claim as a
test case because he seeks an opportunity to develop and present evidence of
additional and alternative causative factors.” Motion to Withdraw Claim as a Test Case,
filed Apr. 10, 2008; ECF No. 40 at 1.

        The only additional evidence from the OAP filed into the record of this case were
transcripts of some of the testimony, including cross examination in the OAP test cases
from several of the experts whose reports were filed earlier into the record of this case.
See Res. Ex. LL, filed Oct. 11, 2011. ECF No. 145. These transcript excerpts were
filed in response to my order of July 12, 2011, for respondent to designate any OAP
hearing evidence on which she intended to rely in this case.

        2. Petitioners’ Motion to Exclude OAP Evidence.

       Petitioners’ April 2013 Motions in Limine included a motion to exclude evidence,
expert reports, medical literature, and witness testimony from the OAP. Id. at 20-25.
ECF No. 227. Petitioners correctly asserted that they were permitted to withdraw from
the OAP when I granted their motion to do so on April 15, 2008. Id. at 21. Further,
because their theory—that A.K.’s vaccination significantly aggravated an underlying
mitochondrial disorder—was not explored in the OAP, they argued that OAP evidence
should be excluded from their case. Id. at 22.

       Petitioners relied on Paluck ex rel. Paluck v. Sec’y, HHS, 104 Fed. Cl. 457
(2012), a case in which the special master relied in part on evidence from the OAP to
decide a case which had not been part of the OAP. In Paluck, Judge Lettow expressed
his concern about this, commenting that the special master could not use his authority
“in a way that deprives a party of procedural rights provided by the Vaccine Act and the
Vaccine Rules.” Paluck, 104 Fed. Cl. at 484 (quoting Simanski v. Sec’y, HHS, 671 F.3d
1368, 1385 (Fed. Cir. 2012)).

       Petitioners also contended that using OAP evidence in their case would violate
the Sixth Amendment’s confrontation clause. Motions in Limine at 24, n.13 (ECF No.
227).77

       Respondent argued that petitioners voluntarily “availed themselves of the OAP
process,” which included the admission of OAP evidence into their case. Res.
Response at 4 (ECF No. 258). According to respondent, petitioners’ claim that the OAP
evidence was not relevant to their new theory does not constitute a basis to exclude the
evidence, because under the less stringent procedural rules and evidentiary practices
applied in the Vaccine Program, relevance affects the evidence’s weight, not its

77This argument is patently absurd. By its terms, the Confrontation Clause of the Sixth Amendment to
the U.S. Constitution applies only to criminal cases. The Vaccine Act does not even require hearings or
extend the right to cross-examine witnesses. § 12(d)(2)(D). I recognize that the issues in this case are
very emotionally charged for petitioners, but ridiculous arguments such as this one detract attention from
whatever merit their other arguments may have.

                                                     43
admissibility. See Moberly v. Sec’y, HHS, 592 F.3d 1315, 1325 (Fed. Cir. 2010); Munn
v. Sec’y, HHS, 970 F.2d 863, 871 (Fed. Cir. 1992).

       In their Reply, petitioners renewed their motion to exclude OAP evidence, again
arguing that it is irrelevant. Pet. Reply at 13 (ECF No. 259). Petitioners called much of
the proffered testimony “irrelevant and outdated.” Id. Further, since petitioners have
were not claiming that thimerosal caused A.K.’s injury, they argued that all OAP
evidence regarding thimerosal or mercury toxicity should be struck from the record. Id.
at 14. They went on to claim that “any neurologist or pediatrician who testified as an
expert in the field in 2008 that [an ASD] epidemic did not exist is not credible,” and thus
the testimony of Drs. Eric Fombonne and Max Wiznitzer’s and their expert opinions
should be struck from the record.78 Id. at 15-17.

        Petitioners also claimed that the Vaccine Act “requires that any condition
asserted in a vaccine case be supported in the medical record” and therefore that any
testimony that A.K. exhibited symptoms of ASD that was not supported in the medical
records was irrelevant. Motions in Limine at 16. They requested that the testimony of
Dr. Bennett Leventhal be struck because he discussed tests that were conducted on a
child in the OAP test case, not A.K.79 Id. at 18.

        3. Legal Standards.

       Special masters have “virtually unlimited” power to “inquire into matters relevant
to causation.” Snyder, 2009 WL 332044, at *2; Whitecotton v. Sec’y, HHS, 81 F.3d
1099, 1108 (Fed. Cir. 1996). Congress “contemplated that the special masters would
develop expertise in the complex medical and scientific issues involved in actual
causation claims and would then apply this expertise to the resolution of other cases.”
Snyder, 2009 WL 332044, at *2. This policy favoring broad inclusion of evidence is
echoed in the Vaccine Rules, which instruct special masters that they are “not…bound
by common law or statutory rules of evidence but must consider all relevant and reliable
evidence governed by principles of fundamental fairness to both parties.” Vaccine Rule
8(b)(1).

        4. Analysis.

      Unlike Paluck, this is not a case where evidence was imported by the special
master from the OAP for use in a case that was not a part of the OAP. The evidence

78That petitioners and their expert, Dr. Shafrir, reject the epidemiological evidence proffered in the test
cases is clear. That disagreement does not give them the authority to control the admissibility of such
evidence. Doctor Shafrir’s opinions on the mainstream approach to ASD’s diagnosis, treatment, and
causes, are discussed at some length in the causation decision in this case. Doctor Shafrir’s opinions
that there is an autism epidemic caused by postnatal environmental factors such as vaccines is rebutted
by the scientific evidence contained in the reports and testimony of these ASD experts from 2008, as well
as the testimony and reports specific to this case.
79I have not relied in any way on Dr. Leventhal’s testimony contained in Res. Ex. LL, but “striking” it is
unnecessary.

                                                      44
petitioners seek to exclude, on the dubious basis that all of the evidence in the OAP is
somehow irrelevant to their case, was actually filed into the evidentiary record in this
case. Regardless of their source, the expert reports, transcripts, and medical journal
articles filed are evidence in this case. Petitioners were well aware of what the
evidentiary record included; they cannot claim surprise or a lack of opportunity to
respond to this evidence.

        The timing for their motion to exclude this evidence is highly suggestive of
gamesmanship. The motion was filed on April 8, 2013. ECF No. 227. I had earlier
extended the deadlines for all pre-evidentiary findings (at petitioners’’ request) with
respondent’s deadline extended to April 1, 2013. Thus, the exclusion of evidence would
effectively preclude respondent filing similar evidence from another source. And, if I
delayed the case to allow them to obtain additional evidence, respondent could simply
file new reports from the same experts or even the same reports again. Neither
scenario would have worked to petitioners’ advantage.

         The OAP evidence not specifically filed into the docket of this case was made
publically available in the OAP test case dockets. The transcripts of the hearing
testimony were likewise made publically available. While, due to copyright restrictions,
the medical and scientific journal articles themselves were not available on the OAP
docket (http://www.cofc.uscourts.gov/docket-omnibus-autism-proceeding), the master
lists of these articles were publically available, and respondent’s Master List, including
all of the medical journal articles on that list, was actually filed into the record of this
case.80 Finally, and most significantly, the detailed and comprehensive decisions of the
special masters were drafted with the purpose of setting forth the available and relevant
evidence for the purpose of not only resolving the specific test cases, but to create a
body of evidence that would aid in resolving the remaining cases.81 Nevertheless, with
the exception of occasional citations to the test case decisions, this evidence was not
used to resolve this case.82 This obviates any need to determine whether OAP

80The causation decision in this case does not rely on any medical journal article not filed into the record
of this case.
81 Although the parties were able to supplement OAP evidence with additional materials, there is nothing
in Autism General Order #1 to suggest that OAP evidence should be excluded from subsequent cases.
Had the OAP produced a ruling on general causation issues favorable to petitioners, they would have
been “ordered to demonstrate that [their] case qualifies for compensation under the general ruling.”
Autism General Order #1 at 6-7. Because the OAP general causation rulings were unfavorable to
petitioners’ case, they received “the opportunity to introduce additional supportive case-specific
evidence.” Id.
82 There exists one limited exception, which involves Dr. Deth. When petitioners indicated that they
intended to use Dr. Deth as one of their experts in this case, I cautioned them that I did not intend to
permit the re-litigation of the theories he had presented in the Theory 2 OAP test cases, absent new
evidence suggesting that the prior resolution was incorrect. I noted that the evidence he presented in the
Theory 2 test cases was not well-received, and urged them to look at the test case decisions before
retaining Dr. Deth. Doctor Deth’s expert report in the OAP was already a part of the record in this case.
When he testified in this case, I recognized that many of the PowerPoint slides he was using were the
same slides he had used during his earlier testimony, to include an illustration from a 1958 medical
journal article purporting to show evidence for a “block” in the transsulfuration cycle in the human brain.
Thus, I have used my own knowledge of Dr. Deth’s testimony in both the test cases and A.K.’s case, as

                                                      45
evidence can be used in other cases that were once a part of the OAP.83

       Perhaps the most disturbing aspect of petitioners’ request to exclude is that
granting it would, in effect, give petitioners control over the source of any evidence
respondent might file. Petitioners were as free as respondent to file information from
the OAP—and, through the testimony of Dr. Deth, they did so.

       Although petitioners claimed that they were not relying on a mercury theory of
causation any longer (a matter not clear until they filed their second amended petition
and which they had expressly reserved the right to do in withdrawing from the OAP), Dr.
Deth talked about mercury on his slide presentation and during his testimony at the
hearing in this case. Additionally, A.K.’s medical records from Dr. Boris reflected that he
was chelated to remove mercury and other “toxic metals” from his body, and reflected
Dr. Boris’s diagnoses related to these matters. While it is undoubtedly true that some of
the matters filed by respondent from the OAP were not precisely relevant to A.K.’s case,
the advantage of a bench trial is that the special master may simply disregard irrelevant
matters after the hearing and post-hearing processes are complete without having to
determine, in advance of hearing the testimony, what is relevant and what is not.

        Generally, “in omnibus proceedings, the parties consent to import evidence from
the ‘test case’ into other individual cases.” Snyder, 2009 WL 332044, at *2 n.8. Here,
petitioners voluntarily agreed to join the OAP. While their case was part of it, they
benefitted from the coordinated litigation efforts of the PSC and the development of new
scientific studies. As part of their agreement, they consented to the inclusion of OAP
evidence in their case. The fact that petitioners later withdrew from the OAP is of no
consequence, because the evidence to which they object is already part of the record in
their case.

well as both of his expert reports in assessing to what degree such testimony overlapped and where it
was distinct. I note that I was concerned enough about the lack of support for Dr. Deth’s opinions, his
practice of cherry-picking data from other researchers, and his misstatements about the findings of other
researchers, and his tendency to offer opinions on matters in which he was not qualified to opine in the
OAP to decline to award interim fees and costs for Dr. Deth’s expenses when I made the first interim fees
award in this case.
83 In one sense, the OAP ended when the PSC disbanded after the conclusion of the appellate
proceedings in the test cases. See Autism Update, Jan. 12, 2011, available at
http://www.cofc.uscourts.gov/docket-omnibus-autism-proceeding (noting the disbandment of the PSC). In
another, based on the intent of the parties when it was created and the purposes behind its creation, all of
the cases that were once a part of the OAP are affected by the evidence created in the test cases. As
Autism General Order #1 indicates, at the time the OAP was created, petitioners acknowledged that there
was insufficient evidence to prove vaccine causation of ASD, but averred that the evidence was
obtainable through a discovery process. Thus, petitioners, including petitioners in the instant case,
whose cases were subject to dismissal for lack of evidence of causation at the time they were filed
achieved a lengthy period of delay. Petitioners in this case were the beneficiaries of that period of delay. It
is highly unlikely that respondent would have entered into the agreement to create an omnibus proceeding,
absent the understanding that the evidence would be available for use in other cases that
were not only once a part of the OAP, but relied on some of the same theories that were presented in the
OAP. This is particularly true in this case, given Dr. Deth’s opinions, testimony, and supporting slides and
literature.

                                                      46
        Petitioners have cited no authority that compels or persuades me to remove
evidence that is already part of the record. Anything filed into the docket in A.K.’s case
while it was part of the OAP that was not subsequently withdrawn on motion by one of
the parties remains part of the record. This includes, inter alia, the reports and CVs
from some 13 experts regarding general causation issues.

        5. Ruling on Motion to Exclude Evidence.

        All of the evidence filed into the record of this case not specifically excluded (by
an earlier order or the granting of an earlier motion to withdraw it) remains a part of the
evidentiary record. The Vaccine Rules favor broad inclusion, and “the probative value
of the evidence or the credibility of the witnesses…are matters within the purview of the
fact finder.” Munn, 970 F.2d at 871. To the extent that petitioners’ motion to exclude
evidence refers to OAP evidence not in the record of this case, it is effectively moot. As
noted above, the causation decision in this case does not rely on any medical literature
not filed in this case. And, although the relationship between Dr. Deth’s testimony in the
OAP and his testimony in the instant case is highly complex, I stress that discussion of
Dr. Deth’s prior OAP opinion pertains to Dr. Deth’s own testimony in this case and my
conclusions regarding Dr. Deth’s qualifications and reliability as an expert, and not as
substantive evidence.84

E. Substitution of Child Development Expert.

       At a March 13, 2013 status conference, petitioners informed me that Dr. Megson,
their pediatric development specialist, was ill and would be unable to participate in the
hearing. They indicated that they were looking for another expert, but it would be
unlikely that any new expert would be prepared to testify at a hearing six weeks hence.
Petitioners suggested that another session of the causation hearing would be
appropriate. Petitioners reiterated this history and their request in the Motions in
Limine, ECF No 227, at 26-29.

         I did not rule on petitioners’ request at the March 13, 2013 status conference, nor
did I indicate that their request to obtain a new expert would not be granted. I did note
that it had taken petitioners some time to find a pediatric development specialist willing
to opine, and suggested that they attempt to find another. The need for a second

84Ultimately, the nature and significance of my citations to Dr. Deth’s prior OAP opinion are bound up in
the substance of his testimony in the present case. Therefore, the extent of my reference to Dr. Deth’s
OAP testimony and its implications are best understood in the context of the causation decision. These
issues are addressed in greater detail therein. I do note, however, that although my discussion of Dr.
Deth’s opinion in this case extensively addresses the similarities between Dr. Deth’s instant presentation
and his previously rejected OAP presentation, that aspect of the discussion represents only a single part
of the overall analysis. It is therefore worth noting that my ultimate conclusion regarding Dr. Deth’s
opinion would remain the same with or without reference to the OAP. Furthermore, I do not rely on any
materials that have not been filed in this case; nor do I discuss any fact or observation not published in
my prior Dwyer decision. Petitioners were therefore fully on notice regarding every aspect of the final
analysis.

                                                     47
session of the entitlement hearing to take the testimony of such a witness could be
discussed once they found an expert. It was also possible that Dr. Megson might
become available, although petitioners could not supply any information about Dr.
Megson’s prognosis for return to work.

       At the April 9, 2013 status conference, we discussed the issue of a replacement
expert. Audio Tr. 2:38-42 (petitioners reported that they intended to replace Dr. Megson
with another unspecified expert, who would provide an expert report by June 1, 2013).

        Post-hearing, petitioners reported that they had found another expert, and I set a
deadline for filing that unidentified expert’s report. ECF No. 257. In July 2013,
petitioners reported that they would not be filing such a report and requested that Dr.
Megson be allowed to testify via video in late summer or fall. ECF No. 272. Less than
two weeks later, citing excessive costs,85 petitioners indicated that they would rely only
on Dr. Megson’s report without the need for further testimony. Status Report, ECF No.
275.

       This renders their motion to obtain a new expert, file that expert’s report, and
take the expert’s testimony moot.86

F. Motion to Strike Dr. Miller’s Testimony.

        1. Motion.

        Doctor Judith Miller, a clinical psychologist specializing in the diagnosis of ASD,
testified on behalf of respondent on April 25, 2013. Her qualifications to opine are set
forth in some detail in the entitlement decision in this case. This was her first
appearance as an expert witness in any court, including the Vaccine Program. Tr. 846.

       Prior to her testimony, Dr. Miller reviewed A.K.’s medical records and home
videos, but did not meet A.K. In summary, she opined that A.K. has autism, the signs of
which were apparent by the time he was 14 months old. Additionally, she opined that
the evidence does not support petitioners’ claims that A.K. experienced a
developmental regression. Tr. at 895-96, 916-19, 938-39. Her testimony was
devastating to petitioners’ theories of causation.

85 Petitioners had not at that point requested another award of fees and costs post-hearing, although this
is a point at which respondent’s objections to interim fee and cost awards often vanishes.
86 In her response to the Motions in Limine, respondent noted that, since I gave petitioners until July 2013
to file an expert medical report from Dr. Megson’s replacement (Post-Hearing Order, issued May 1, 2013,
at 2), the motion was moot. Res. Response at 6 (ECF No. 258). Respondent asked me to defer making
a determination about hearing testimony from the substituted expert “until after the new opinion has been
filed and respondent has had an opportunity to file a response.” Id. Petitioners agreed with respondent’s
request, asking for a “deferral of any outstanding issues regarding additional expert testimony to the time
when such testimony is proffered.” Pet. Reply at 19 (ECF No. 259).

                                                     48
        In their post-hearing memorandum [“Pet. Post-Hearing Memo”], petitioners
argued that Dr. Miller’s testimony should be stricken in its entirety. Pet. Post-Hearing
Memo, filed May 5, 2014, at 34 (ECF No. 297). They claimed that Dr. Miller was
inconsistent in her evaluation of A.K.’s medical records; that she was neither credible
nor reliable; and that her testimony was “completely without foundation.” Id.

        Petitioners offered several arguments in support of their request to have Dr.
Miller’s testimony stricken. First, petitioners contended that her testimony was
contradictory, claiming that at times she was criticizing A.K.’s physicians for failing to
note certain developmental issues and at another insisting that “there are no universal
predictors of autism.”87 Pet. Post-Hearing Memo, filed May 5, 2014, at 30 (ECF No.
297).88

        They claimed that during cross examination Dr. Miller was unable “to articulate
the basis for her conclusions,” identify “red flags” in A.K.’s early medical records, or
point to any records that supported her conclusions. Id. They believed that Dr. Miller
misinterpreted many of A.K.’s pediatric records, see id., and discounted [A.K.’s
parents’] observations of their son’s development. Id. at 31.

       Finally, petitioners argued that Dr. Miller’s statement that evaluating motor skills
was outside her area of expertise should result in her testimony being stricken, as “[a]
witness cannot be permitted to claim expertise allowing her to express opinions
concerning pediatric practices and then deny her own expertise in the same area.” Id.
at 31, n.17. Petitioners did not, however, cite any legal authority for striking testimony in
a bench trial.

        In her Response to Petitioners’ Post-Hearing Memorandum [“Res. Response”],
respondent countered each basis for petitioners’ motion to strike. Res. Response, filed
Jun. 16, 2014, at 1-3 (ECF No. 301). Respondent described Dr. Miller as “the most
qualified expert in this case to testify regarding the onset of [A.K.]’s autism.” Res.
Response at 1-2 (emphasis in original). Respondent argued that petitioners’ statements
in their Post-Hearing Memo were “inflammatory hyperbole” in addition to being “simply
untrue.” Res. Response at 2. Respondent contended that Dr. Miller’s testimony had an
adequate foundation, given her review of medical records and home videos, the medical
literature she referenced, and “her knowledge of how autism manifests during the first
two years of life.” Res. Response at 2.

        Respondent also offered a more nuanced and factually correct view of Dr.

87Petitioners wrote: “Most telling in the context of Dr. Miller’s criticism of AK’s contemporaneous treating
physicians’ failure to observe AK’s developmental issues at this time, was her testimony ‘that there are no
universal predictors of autism.’ Tr. at 870, lines 1-8; 871, lines 5-9.” I note that Dr. Miller did not use
precise the words appearing in quotation marks, although I agree that that was the essence of her
testimony. I caution petitioners against citing phrases as direct quotations when they are not.
88In the next page of their Post-Hearing Memo, petitioners claim that “virtually all Dr. Miller’s testimony
contained blanket criticism not only of AK’s pediatricians, but of virtually every other medical specialist
involved in his treatment, diagnosis, and care.” Pet. Post-Hearing Memo at 31 (ECF 297).

                                                      49
Miller’s testimony, stating that “Dr. Miller was not admonishing” A.K.’s physicians for
failure to recognize his autistic features, because “based on what was known about
autism at the time, they would not have been expected to know what to look for.” Id. I
concur. There was never a time when Dr. Miller’s tone or demeanor suggested she was
being critical of or condescending to the treating doctors.

        Regarding petitioners’ statement that Dr. Miller limited her own expertise,
respondent argued that she admitted that she was not a medical doctor, and “it was
therefore entirely appropriate for her to decline to offer opinions on issues involving
diagnosis and treatment of [A.K.]’s physical health.” Id. at 2-3. In respondent’s view,
Dr. Miller’s lack of a medical degree did not render her unqualified to identify the early
symptoms of autism; “[i]ndeed, her training and experience abundantly qualify her to
opine on those issues.” Id. at 3. In response to the allegation that Dr. Miller discounted
parental reports of A.K. experiencing a regression, respondent argued that the
physician in whose records the notation appears was unlikely to have “fact checked”
A.K.’s earlier medical records and independently verify that A.K.’s parents’ account was
accurate. Id. During her testimony, Dr. Miller explained that parental reports of a
regression that are given years after the fact are difficult to rely upon. Id., see also Tr.
at 940. In respondent’s view, although Dr. Miller’s testimony was damaging to
petitioners’ claim, it was “well-supported and reliable.” Id.

       2. Legal Standards.

              a. Authority to Exclude Unreliable Evidence.

        Under the Vaccine Act, a special master must consider all relevant scientific and
medical evidence contained in the record, but the record itself is established by the
court. 42 U.S.C. § 300aa-13(b)(1)(c). A special master must consider “all relevant and
reliable evidence, governed by principles of fundamental fairness to both parties.”
Vaccine Rule 8(b)(1). Special masters are required to consider the record as a whole.
§ 13(b)(1). Taken together, these provisions have been interpreted to grant special
masters the discretionary authority to exclude unreliable evidence from the record on a
motion in limine. Verzyer v. Sec’y, HHS, No. 06-522V, 2010 WL 2507791, at *20-22
(Fed. Cl. Spec. Mstr. June 15, 2010), aff’d, 98 Fed. Cl. 214, 222 (2011)

       A special master may, in her discretion, exclude evidence, but there is no
statutory requirement that she do so in any particular instance. Id. at *19-20. Exclusion
of evidence in vaccine cases is an “exceptional remedy,” proper only where the opinion
of the proffered expert is “completely unreliable.” Verzyer, 2010 WL 2507791, at *21-
22.

              b. Determining Reliability.

       Although the Federal Rules of Evidence do not apply to vaccine litigation, the
factors for determining reliability of expert testimony enunciated in FRE 702 and
Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993) can be used as a

                                             50
framework for special masters in considering the reliability of an expert’s opinion.
Verzyer, 98 Fed. Cl. at 223; see also Cedillo, 617 F.3d at 1339; Terran v. Sec’y, HHS,
195 F.3d 1302, 1316 (Fed. Cir. 1999). The Daubert factors are: (1) whether the theory
has general acceptance in the scientific community; (2) whether the theory has been
subjected to peer review and publication; (3) whether it can and has been tested; and
(4) whether the known potential rate of error is acceptable. Daubert, 509 U.S. at 593-
94.

       A Daubert analysis is appropriate in any case involving “scientific, technical, or
other specialized knowledge.” Kumho Tire Co. v. Carmichael, 526 U.S. 137 (1999).
The Supreme Court has cautioned fact-finders that “conclusions and methodology are
not entirely distinct from one another…A court may conclude that there is simply too
great an analytical gap between the data and the opinion proffered.” Gen. Elec. Co. v.
Joiner, 522 U.S. 136, 146 (1997).

         A special master is not required to consider the Daubert factors when
determining the reliability of expert testimony in vaccine cases (Garcia v. Sec’y, HHS,
No. 05-720V, 2010 WL 2507793 (Fed. Cl. Spec. Mstr. May 19, 2010), at *8), but doing
so may be useful when assessing “general medical issues” (Terran, 195 F.3d at 1316).
Rarely, special masters have found an expert sufficiently unqualified and unreliable so
as to warrant exclusion on respondent’s motion. See Veryzer, 2010 WL 2507791. In
Veryzer, the court excluded testimony from an expert who “openly flaunt[ed] that he
does not follow accepted medical science,” did not show any of the Daubert indicia of
reliability, and lacked clinical experience treating patients with the same condition as the
petitioner. Verzyer, 2010 WL 2507791, at *3, *22-23. The testimony of a second expert
was also excluded; her credentials as a doctor of osteopathy and previous board-
certification as a doctor of emergency medicine did not render her qualified to testify as
to neurological diagnoses, and her ideas had not been subject to critical analysis by
others in the field or in peer-reviewed medical journals. Id. at *25. The court stated that
the testimony of these experts was “manifestly…unhelpful” and “thoroughly worthless,”
respectively, due to a lack of relevance to the resolution of the issues presented in the
case. Id. at *25-26.

        In addition to the Daubert factors, the court may consider an expert’s
qualifications to testify on particular subjects when weighing expert testimony. Bast v.
Sec’y, HHS, No. 01-565V, 2012 WL 6858040, at *21 (Fed. Cl. Spec. Mstr. Dec. 20,
2012) (a special master may consider “any specialized knowledge, experience, training,
or education of the witness that would inform the offered opinion”). When making
determinations about an expert’s credibility, special masters consider whether the
expert’s qualifications bear on the specific substantive area about which the expert is
testifying.

              c. Vaccine Act Practice: Evaluation and Exclusion.

       Special masters routinely undertake a careful consideration of an expert’s
experience in a particular area. For instance, in Pafford, the court questioned an

                                             51
expert’s qualification because he lacked certification in the specialized areas about
which he testified. Pafford v. Sec’y, HHS, 451 F.3d 1352 (Fed. Cir. 2006). Similarly,
the court in Locane afforded greater weight to the testimony of a physician who routinely
treated patients with the disease in question than it did to one who did not. Locane v.
Sec’y, HHS, 99 Fed. Cl. 715 (2011). In Waleryszak, the Court of Federal Claims upheld
the special master’s decision to afford less weight to the testimony of a pediatrician who
did not specialize in the diagnosis of neurological dysfunctions. Waleryszak v. Sec’y,
HHS, 45 Fed. Cl. 573 (1999).

        On occasion, special masters have excluded sua sponte the expert testimony of
non-medical doctors who wished to opine on matters far removed from their areas of
expertise. See, e.g., Domeny v. Sec’y, HHS, No. 94-1086V, 1999 WL 199059 (Fed. Cl.
Spec. Mstr. Mar. 15, 1999), aff’d, 232 F.3d 912 (Fed. Cir. 2000) (excluding the
testimony of an expert witness with degrees in dentistry and public health who intended
to opine on diagnosis and duration of petitioner’s non-dental medical condition); Ruiz v.
Sec’y, HHS, No. 02-156V, 2007 WL 5161612 (Fed. Cl. Spec. Mstr. Mar. 14, 2007)
(striking the testimony of a psychologist who opined on causation after he admitted he
was not trained to diagnose neurological illnesses); Smith v. Sec’y, HHS, No. 08-874V,
2009 WL 4020253, at *3 (Fed. Cl. Spec. Mstr. Oct. 30, 2009) (excluding the testimony
of a non-medical doctor chiropractor who wished to opine on causation of fibromyalgia).

        Non-medical doctors have been allowed to testify as experts in vaccine cases
about issues that fall within the purview of their training and experience. See, e.g.,
Snyder, 2009 WL 332044, at *17, *19 (Dr. McCabe, a non-medical immunotoxicologist,
was described as having “impeccable qualifications” in that field; similarly, Dr.
MacDonald, a non-medical doctor with training in immunology who had performed
extensive research on the human gastrointestinal system, was “eminently qualified to
testify on diseases and immunology of the digestive system”). A proffered expert’s lack
of a medical degree “does not preclude his testimony as to facts commonly accepted
within the scientific community to which he belongs.” Pet. Post-Hearing Memorandum
at 122 (citing White v. United States, 399 F.2d 813, 820 (8th Cir. 1968); Harris v. Smith,
372 F.2d 806, 813-14 (8th Cir. 1967); Sher v. De Haven, 91 U.S. App. D.C. 257, 199
F.2d 777, 782, cert. denied, 345 U.S. 936 (1953); Hill v. Gonzalez, 454 F.2d 1201, 1203
(8th Cir. 1972).

        When the testimony of non-medical doctors has been excluded, it has generally
been because their lack of medical degree bore some relation to their lack of
experience or some other Rule 702 qualification. For example, in Domeny, the
testimony of a dentist was excluded because he was not qualified to give an opinion
about the diagnosis and duration of Guillan-Barre Syndrome. The court noted that he
was not a medical doctor, and his experience in “dental behavioral science, dental
public health, health education and promotion, behavioral science, humanistic
psychology, psychosocial factors influencing substance abuse and oral hygiene
behaviors, and the effects of marijuana smoking on cardiovascular and respiratory
stress response mechanisms” was irrelevant when determining what medical condition
petitioner had and for how long. Domeny, 1999 WL 199059, at *14. In doing so, the

                                            52
court based its exclusionary authority on cases where courts “refused to let persons
testify who have little experience or education in the substantive area in which they are
being proffered as an expert.” Id. at *15 (citing Hidden Oaks Limited v. City of Austin,
138 F.3d 1036, 1050 (5th Cir. 1998) (upholding the trial court’s refusal to allow a witness
to give expert testimony on the value of land when the witness was not a licensed
appraiser or real estate broker and was unfamiliar with standard appraisal methods);
Barrett v. Atlantic Richfield Co., 95 F.3d 375, 382 (5th Cir. 1996) (a witness was not
permitted to give expert testimony as to the scientific correlation between chemical
exposure and chromosomal damage in humans due to the expert’s limited expertise
and background in the subject area)). The fact that a proffered expert is not a medical
doctor does not necessarily render her unqualified to opine on areas within her area of
substantive expertise.

         Generally, special masters consider all of the evidence and then assess its
reliability in determining how much weight to afford it. Fester v. Sec’y, HHS, No. 10-
243V, 2013 WL 5367670, at *13 n.28 (Fed. Cl. Spec. Mstr. Aug. 27, 2013). Because
special masters serve as both fact-finders and judicial officers, and because they have
developed an expertise that lay jurors have not, they do not need the same procedural
protection that excluding testimony at the outset provides. Garcia, 2010 WL 2507793,
at *8. When making entitlement decisions, a special master must first assess the
reliability of each expert’s theory against the facts of the case and the backdrop of
accepted medicine, and then comparatively weigh the competing theories for
persuasiveness. Id.

       The concept of reliability is interwoven with the causation standard in Vaccine Act
cases, which requires petitioners to demonstrate a “legally probable” medical
explanation (Knudsen, 35 F.3d 548-49), a “logical sequence of cause and effect
showing that the vaccination was the reason for the injury” (Althen v. Sec’y, HHS, 418
F.3d 1274, 1278 (Fed. Cir. 2005)), and “onset of symptoms during a timeframe for
which, given the medical understanding of the disorder’s aetiology, it is medically
acceptable to infer causation-in-fact.” (de Bazan, 539 F.3d 1352. See also Althen, 418
F.3d at 1278. In cases under the Vaccine Act, the court is not required to conduct a
threshold inquiry into reliability separate from the examination of causation in the
absence of a timely motion by a party. Garcia, 2010 WL 2507793, at *11. In addition, if
a party does not make a timely motion to exclude evidence based on a lack of reliability,
their objection is waived. Id.

       3. Applying Legal Standards to Dr. Miller’s Testimony.

       Doctor Miller was eminently qualified to opine on the symptoms of ASD; how they
manifest; how ASD is diagnosed; and how medical records, parental histories,
diagnostic testing, and video evidence all contribute to an ASD diagnosis. She not only
diagnoses ASD herself, she teaches others how to perform such diagnoses. Res. Ex.
PP at 1-3; Tr. at 847-48. Psychologists, psychiatrists, developmental pediatricians, and
pediatric neurologists all perform such diagnoses. See, e.g. King, 2010 WL 892296, at
*79 (noting that “autism is considered a neurologic and a psychiatric disorder” and that

                                             53
“psychologists are also often specialists who diagnose autism.”); see also Synder, 2009
WL 332044, at *32 (noting that “[a]ll of the disorders falling within the autism spectrum
are defined by a collection of symptoms or behaviors. With the exception of Rett’s
disorder, all ASDs are diagnosed by comparing behavioral symptoms exhibited by a
child against an established set of broad diagnostic criteria. The diagnosis is made by
direct observation, videos of the child, and from parental reports, as there is no
biochemical test for ASD.”); Dwyer, 2010 WL 892250, *33 n.136; Tr. at 857-58 (Dr.
Miller testifying about her extensive history of diagnosing patients with ASD).

        Doctor Miller performs her duties at one of the premier pediatric medical facilities
in the United States, the Children's Hospital of Philadelphia, in the Center for Autism
Research. Tr. 847. Moreover, her opinions on onset, symptoms, and diagnosis were
buttressed by those of another well-qualified witness, Bruce Cohen, M.D. Res. Ex. SS
at 6, 8; Tr. 1383-87, 1148-49. She has more publications on the topic of ASD than any
of petitioners’ own experts. Compare Res. Ex. PP. at 4-8 (Dr. Miller), with Pet. Ex. 62 at
4-8 (Dr. Shafrir), Tr. 238 (Dr. Kendall).

       In addition to her exemplary qualifications to offer opinions, she was a superb
expert witness, in spite (or perhaps because) of her lack of courtroom experience. In
nearly 10 years as a special master (and seven more as a criminal court trial judge), I
have heard testimony from well more than 200 experts, and I would rank Dr. Miller in the
top 5% of those I have heard. She was well-versed in the medical records in this case;
she explained her opinions clearly and cogently, without standing on a soapbox or
displaying the unfortunate tendency to be loyal to the party paying her at the expense of
candor; and, even when the cross-examination bordered on being argumentative and
hostile, she maintained her composure.

       Qualifications aside, there are a myriad of other reasons to deny petitioners’
motion to strike her testimony. First and foremost, her testimony has already been
heard. Petitioners first moved to exclude it in their post-hearing brief. Had they truly
thought she lacked the qualifications to opine, they should have raised the issue prior to
her testimony. This belated objection suggests that motion was based more on the
damage she did to their case than on problems in either her qualifications or testimony.
In Garcia, respondent first argued for the exclusion of an expert’s testimony in her post-
hearing brief, after the testimony had already been heard. The special master
concluded that respondent had waived her objection to the admission of the testimony.
Garcia, 2010 WL 2507793, at *1. Although I elect to address the merits of the motion, I
concur with the special master’s ruling in Garcia that such motions post-hearing are
untimely.

        Any deficiencies in the reliability of Dr. Miller’s testimony are more appropriately
addressed in the assignment of weight to her testimony rather than its wholesale
exclusion. Further, even if exclusion were proper from a procedural perspective,
petitioners’ objections to the “inconsistencies” in Dr. Miller’s methodology and “lack of
foundation” for her conclusions are not a basis for exclusion. Unlike the expert in
Veryzer, Dr. Miller’s views do not contradict accepted science; indeed, they were well

                                              54
supported by medical journals and other experts. I add that I heard her testimony, the
cross-examination questions, and Dr. Miller’s answers, and any “inconsistencies” and
“lack of foundation” exist only in the perceptions of petitioners and their counsel.

         I stress that although I have considered all of petitioners’ objections to Dr. Miller’s
testimony, I have not only found that they are without merit, in many regards they are
gross misrepresentations. For example, in their response to respondent’s post-hearing
brief, petitioners argued that Dr. Miller had criticized Dr. Rapin for not following
“appropriate medical protocol” in arriving at her diagnosis. ECF No. 302 at 7.
Petitioners’ counsel engaged cross-examined Dr. Miller on this point, during which Dr.
Miller was quite clear in stating that petitioners’ counsel was incorrect in summarizing
Dr. Miller’s testimony as being critical of Dr. Rapin for using insufficient diagnostic
criteria in A.K.’s case. Tr. 983-84. Rather, Dr. Miller testified that Dr. Rapin likely relied
at least in part on parental reports, and that it is not standard medical practice to fact-
check parental reports. Tr. 984-85. Petitioners characterize this as “ironic,” because
Dr. Miller’s own diagnostic tools rely on parental reports (ECF No. 302 at 8), but there
was nothing ironic in Dr. Miller’s testimony. She simply offered what should be an
uncontroversial observation – that parental reports can provide important information,
but that not all parental reports are equally reliable. In that regard, Dr. Miller explained
that parental reports can be assessed for their reliability by “drilling down” with follow up
questions that call for concrete examples and by matching up parental claims to what is
observed clinically. Tr. 948-50. Contrary to petitioners’ argument, Dr. Miller did not
testify that this was not done in A.K.’s case, only that it cannot be confirmed and
therefore the reliability of those reports is an open question. I note that, given the
descriptions in school and treatment records, by four years of age, A.K.’s presentation
was so clearly that of a child with ASD that it was unnecessary for Dr. Rapin to question
the history provided.

        In another example of overreaching, petitioners argued that Dr. Miller should be
discredited on the basis that she indicated that A.K.’s influenza vaccinations were not
recorded in his “official” immunization record. Petitioners claim that this statement
demonstrated Dr. Miller’s lack of familiarity with pediatric practice. ECF No. 297 at 27-
28. The point that Dr. Miller made in her report is quite clear: she wrote that she could
find no notation of A.K.’s first influenza vaccination in either his “official” vaccine record,
referring to the page of A.K.’s medical records constituting his “vaccine administration
record” (Res. Ex. OO at 2 (citing Pet. Ex. 2, p. 2.), nor in the progress note for the visits
surrounding the date at which he received the vaccine (Res. Ex. OO at 2 (citing Pet Ex.
2, p. 21.)89 Instead, she pointed out, the influenza vaccine is only noted in a summary
of vaccinations. Res. Ex. OO at 2 (citing Pet. Ex. 2, p. 1. and Pet. Ex. 61, p. 4). Unlike
the administration record, the vaccine summary lacks parental signatures or an
administrator signature and/or initials. Compare Pet. Ex. 2, p. 1 and p. 2. Particularly in
light of Dr. Miller’s clear citation to the precise record she was characterizing as

89Pet. Ex. 2, p. 21 contains what appear to be telephone calls on October 23, 2001 and November 16,
2001. There are no records documenting an office visit to receive a vaccination on November 2, 2001.
The only other November 2001 visit was the well-child visit on November 21, 2001, and there is no
mention that an influenza vaccination was ordered in that record. Id., p. 20.

“official,” petitioners’ belaboring of Dr. Miller’s word choice is not a persuasive argument
regarding Dr. Miller’s fitness as an expert witness.

        The extent of the testimonial evidence that no vaccine record can be considered
“official” was Dr. Shafrir’s general umbrage at the idea that any “official” immunization
record could even be thought to exist. Doctor Shafrir was obviously disdainful of Dr.
Miller as a non-pediatrician or even a physician, and it was this attitude, rather than any
actual misunderstanding of Dr. Miller’s reference to the records, that shaped his
testimony. Tr. 506-510.

       Furthermore, Dr. Miller was not wrong in contending that there is an “official”
vaccination record. See § 300aa-25 (requiring that each health care provider who
administers a vaccination shall record in a permanent medical record or office log the
date of administration, the manufacturer and lot number, the name and address of the
health care provider, and other information required by regulation). The only record that
meets this definition in A.K.’s case is the vaccine administration record. Even if I
thought that Dr. Miller’s word choice was a poor one, there is no question as to what her
underlying point was and no evidence to suggest that Dr. Miller was confused regarding
the nature of the records she reviewed.90

        4. Denying Motion to Strike.

         Although a special master is permitted to exclude unreliable evidence in vaccine
injury cases, expert testimony is rarely excluded in its entirety unless it is completely
unreliable. The special master is not required to undertake a threshold inquiry into the
reliability of expert testimony, and if no timely motion is made, the parties waive any
objection to inclusion of expert testimony in the record. Instead, in most cases the
special master will take into account the reliability of an expert when assigning her
testimony weight. In assessing the reliability of evidence already admitted, the special
master may apply the principles of the Federal Rules of Evidence and Daubert, all of
which, in this case, favor the admission of Dr. Miller’s testimony in its entirety.

        Petitioners’ Motion to Strike is DENIED.

G. Prepayment or Preapproval of Fees.

       Petitioners requested clarification and reassurances from me that they would be
reimbursed for the fees and costs of their expert witness, Dr. Deth, as “they were not in
a position to jeopardize their financial status by advancing large sums of money for

90 I add that, had respondent not conceded that A.K. received the two influenza immunizations as alleged,
this might have been a far different and far simpler case. As reflected in the summary of A.K.’s medical
records as set forth in the entitlement decision in this case, the only record in which the initial influenza
vaccination appears is the summary sheet, in spite of [A.K.’s mother’s] testimony that it was received at
A.K.’s pediatrician’s office. And, there remain unanswered questions surrounding the administration of
the second vaccination, but I accept respondent’s concession that it was administered as reflected in
[A.K.’s mother’s] medical record.

                                                      56
witnesses that the Court would subsequently deny.” Motions in Limine at 29 (ECF No.
227).

       Doctor Deth had testified on behalf of petitioners in the Theory 2 OAP test cases
in support of the position that thimerosal exposure could cause autism. The special
masters’ decisions in the Theory 2 test cases concluded that there was no reliable
evidence to support petitioners’ theory. Dwyer, 2010 WL 892250; King, 2010 WL
892296; Mead, 2010 WL 892248. This included Dr. Deth’s theories about mercury
causing oxidative stress which impacted on the transsulfuration cycle. The special
masters were quite critical of the testimony and opinions of Dr. Deth in their decisions.

        In their motion regarding payment of Dr. Deth’s expert fees and costs, petitioners
explained that they were not using the same theory in their case, and moreover, that
they withdrew from the OAP before the entitlement hearings in the Theory 2 test cases
were conducted. Motions in Limine at 31 (ECF No. 227). They questioned whether I
had prejudged his testimony and sought reassurance that they would be reimbursed for
his appearance, as I had previously cautioned them that I did not intend to allow them to
relitigate the Theory 2 cases without additional evidence. Given that, in withdrawing
from the OAP and as a Theory 2 test case, petitioners had reserved the right to rely on
the theories advanced in the OAP, this caution was particularly applicable to their
presentations at any subsequent entitlement hearing.

        Respondent noted that petitioners had not demonstrated that the amounts they
requested—or even presenting Dr. Deth’s testimony at all—were reasonable. Res.
Response at 5 (ECF No. 258). Respondent contended that a determination about the
reasonableness of Dr. Deth’s fees could only be made once the case is concluded and
“after a proper and timely costs application is filed.” Id. at 6.

       In their Reply, petitioners acknowledged that their motion was moot, “as the
funds are already expended or committed.” Pet. Reply at 18 (ECF No. 259). They
noted their intent to file for interim fees and costs.

       Petitioners have received two interim awards of fees and costs. See ECF Nos.
215 and 312. The total award to date is nearly $460,000.00 dollars. This total does not
include my $5,000.00 award for advance payment of interim costs for Dr. Frye, a
decision which was withdrawn when petitioners’ expert was unable to opine due to
changed circumstances. See ECF Nos. 121 (decision awarding advance interim costs);
123 (respondent’s motion for reconsideration); 124 (denial of motion to reconsider); 128
(order withdrawing fees decision, based on petitioners’ report that the expert could no
longer opine). None of the fees and costs awarded in these decisions was specific to
Dr. Deth.

       Whether Dr. Deth’s fees and costs will ultimately be paid remains an open
question—one that cannot be answered until an application, supported by invoices, is
made. Given the significant duplication of his OAP testimony at the hearing in this case,
questions about the reasonableness of his presentation (and the hours to be paid, if at

                                            57
all), are almost certain to be raised.

                                         III. Conclusion.

       The record in this case is now settled. In summary, petitioners’ motion to
subpoena Dr. Zimmerman is DENIED. Petitioners’ motion to invoke estoppel
against respondent on the basis of the Poling Rule 4(c) report or other evidence
is DENIED. Petitioners’ motion to exclude evidence from the OAP is DENIED.
Petitioners’ motion to substitute a child development expert is MOOT. Petitioners’
motion for prepayment of fees is MOOT. Petitioners’ motion for leave to file
additional exhibits is GRANTED IN PART AND DENIED IN PART. Petitioners’
motion to strike the testimony of Dr. Miller is DENIED.

IT IS SO ORDERED.
