III. DISCUSSION.

A. Jurisdiction.

The United States Court of Federal Claims has jurisdiction to review the decision of a Special Master in a vaccine-related injury case, pursuant to 42 U.S.C. § 300aa-12(e)(2) and Vaccine Rule 23(a). After reviewing the Special Master’s decision, the court may:

(A) uphold the findings of fact and conclusions of law of the special master and sustain the special master’s decision,
(B) set aside any findings of fact or conclusion of law of the special master found to be arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law and issue its own findings of fact and conclusions of law, or
(C) remand the petition to the special master for further action in accordance with the court’s direction.

42 U.S.C. § 300aa-12(e)(2); see also Vaccine Rule 27 (same).

B. Standard Of Review.

The United States Court of Federal Claims may set aside the decision of a Special Master if findings of fact or conclusions of law are found to be “arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law.” 42 U.S.C. § 300aa-12(e)(2)(B). “Fact findings are reviewed ... under the arbitrary and capricious standard; legal questions under the ‘not in accordance with law standard; and discretionary rulings under the abuse of discretion standard. The latter will rarely come into play except where the special master excludes evidence.” Munn v. Sec’y of Dep’t of Health & Human Servs., 970 F.2d 863, 870 n. 10 (Fed.Cir.1992).

C. The Elements And Burden Of Proof In Vaccine Act Cases.

The Vaccine Act provides that a petitioner may receive compensation and other relief under the Vaccine Injury Compensation Program (“Vaccine Program”), if injury can be established either by causation in law or causation in fact. Causation in law is established if one of the vaccines listed in the Vaccine Injury Table at 42 U.S.C. § 300aa-14(a) (“Vaccine Table”) was administered to a petitioner, and the “first symptom or manifestation of onset or of the significant aggravation of such injuries, disabilities, illnesses, conditions, and deaths” of specific adverse medical conditions associated with the use of each vaccine occurred within a time period specified in the Vaccine Table. See 42 U.S.C. § 300aa-14(a); 42 C.F.R. § 100.3(a). The Vaccine Table is to be read and interpreted by reference to “Qualifications and aids to interpretation,” that define the key terms used therein. Id.

Congress also afforded a petitioner the opportunity to receive relief under the Vaccine Program, even if the time period for the first symptom or manifestation of a specified injury is not listed in the Vaccine Table. See 42 U.S.C. § 300aa-ll(e)(l)(C)(ii), § 300aa-13. These types of injuries are known as “off-Table” vaccine injuries. Under these circumstances, a petitioner must establish causation in fact, by offering sufficient facts to establish each element of a vaccine injury claim, and meeting the burden of proof as to each element of the claim by a “preponderance of the evidence” standard. See 42 U.S.C §§ 300aa-13. Accordingly, an off-Table petitioner must proffer at least some evidence as to each element of the claim and sufficient evidence to persuade the Special Master or court by a preponderance of evidence. Id.

In Capizzano v. Sec’y of Health & Human Servs., 440 F.3d 1317 (Fed.Cir.2006), the United States Court of Appeals for the Federal Circuit re-affirmed the three-part test established in Althen v. Sec’y of Health & Human Servs., 418 F.3d 1274, 1278 (Fed.Cir.2005) (“Althen ”), for determining causation in fact in off-Table vaccine injury cases. Althen requires a petitioner to:

show by preponderant evidence that the vaccination brought about [the] injury by providing:
(1) a medical theory causally connecting the vaccination and the injury;
(2) a logical sequence of cause and effect showing that the vaccination was the reason for the injury; and
(3) a showing of a proximate temporal relationship between vaccination and injury-

418 F.3d at 1278.

If a petitioner is able to establish causation in fact, then the burden of proof shifts to the Government to establish that a factor urn-elated to the vaccine was the actual cause of the petitioner’s injury. See 42 U.S.C. § 300aa-13(a)(l)(B); see also Althen, 418 F.3d at 1278 (“If [a petitioner] satisfies this burden, she is entitled to recover unless the [the Government] shows, also by a preponderance of evidence, that the injury was in fact caused by factors unrelated to the vaccine.”).

D. The Special Master’s September 28, 2015 Decision.

In a 161-page decision, the Special Master addressed three issues: whether the influenza vaccinations aggravated A.K.’s underlying mitochondrial disorder; whether A.K.’s ASD predated the influenza vaccinations; and whether Petitioners’ theories of causation met the preponderance of the evidence standard. Dec. at 9.

First, the Special Master determined that Petitioners had not sufficiently established that A.K. had an underlying mitochondrial disorder. Dec. at 46. To reach this conclusion, the Special Master examined the expert evidence the parties provided. Both parties’ experts agreed that there is much uncertainty in diagnosing mitochondrial disorders and that the field has not yet come to a consensus on a standardized criteria. Dec. at 49; see also 4/22/2013 TR 249-49 (direct examination of Dr. Frances Kendall, Petitioners’ expert); see also 4126/2013 TR 1351 (cross examination of Dr. Bruce Cohen, the Government’s expert). Nevertheless, Petitioners proffered two primary pieces of evidence.

The first piece is a diagnosis from Dr. John Shoffner, who after performing a series of tests and reviewing the results, diagnosed A.K. with “probabl[e] mitochondrial encepha-lomyopathy.” Pet. Ex. 32, at 3. The second piece was an expert opinion from Dr. Frances Kendall, who supported Dr. Shoffner’s diagnosis, concluding that “clinical features and laboratory data collected to date provide support for a definitive or highly probable mitochondrial disease[.]” Pet. Ex. 65 at 7. Dr. Kendall used the Bernier criteria, a diagnostic tool used to evaluate mitochondrial disease. Pet. Ex. 65 at 7; see also Dec. at 49. On cross examination, however, Dr. Kendall admitted that “she could not reach a definite mitochondrial disorder diagnosis by applying the Bernier criteria.” Dec. at 50 (citing 4/22/2013 TR 319) (“COUNSEL: So is it still your position that the data and the clinical features support a definitive or highly probable mitochondrial disease diagnosis? DR. KENDALL: I would say probably probable ... with the understanding it’s not definitive.”). Two of Petitioners’ other experts discussed mitochondrial disorders, but “both indicated that they deferred to other experts on the diagnosis of mitochondrial disorder.” Dec. at 49 n. 117.

The Special Master also analyzed Dr. Kendall’s interpretation of the Bernier criteria together with three indicators: enzymology results, metabolic indicators, and clinical features. Dec. at 54. The Special Master found that while enzymology would support a mitochondrial disorder diagnosis, “A.K.’s re-suits [did] not fall low enough to be considered an abnormal finding under Bemier[.]” Dee. at 54. With respect to metabolic indicators, Dr. Kendall stated that “persistent, significant elevations in lactate” indicate mitochondrial disorder. Dec. at 57 (quoting Pet. Ex. 65, at 5). Dr. Kendall, however, “acknowledged that a single instance of elevated lactic acid compared to multiple instances of normal findings would not be indicative of persistent, significant elevation.” Dec. at 58 (citing 4/22/201S TR 816). With respect to clinical features, the Special Master did “not see any indication that Dr. Kendall would diagnose a mitochondrial disorder based on clinical features alone.” Dec. at 63. The Special Master also found that Petitioners’ experts collectively did “not reflect any independent application of the diagnostic standards of any interpretive analysis of Dr. Shoffner’s findings.” Dec. at 65.

Because Petitioner’s primary mitochondrial disorder expert, Dr. Kendall, changed her opinion on the probability of A.K.’s mitochondrial disorder diagnosis, the Special Master determined that Petitioners did not establish that A.K. had an underlying mitochondrial disorder.

Second, the Special Master determined that A.K.’s ASD was not temporally related to his vaccinations, because the Special Master found evidence that A.K.’s ASD symptoms predated the 2001 influenza vaccinations. Dec. at 68. Here, the Special Master considered the testimony of Dr. Judith Miller for the Government and Dr. Yuval Shafrir for Petitioners. Dec. at 68-69.

Dr. Miller concluded that A.K. demonstrated symptoms of ASD before AK. received the influenza vaccinations. Dee. at 77. To reach this conclusion, Dr. Miller relied primarily on analysis of home videos of A.K. rather than A.K.’s pediatricians’ clinical observations. Dec. at 71-72. This is because “at the time A.K. experienced the onset of his ASD, screening techniques for one to two year [olds] were not yet available.” Dec. at 71 (citing 4/25/2012 TR 1047-50). Dr. Miller noted that home videos as far back as January 2001 demonstrated that A.K. had ASD. Dec. at 77. Specifically, Dr. Miller testified that, in a June 2001 home video, A.K. did not demonstrate “age appropriate, purposeful play with [a] [baseball] bat.” Dec. at 77. In another video, dated August 26, 2002, A.K. failed to respond to his name several times, a “big red flag” in terms of ASD screening. Dee. at 88 (citing 4/25/2012 TR 1008 (cross examination of Dr. Miller)). In a November 9, 2001 video, A.K. displayed ASD behaviors such as a cognitive inability to recognize that a wrapped birthday present was for him and seemed more focused on the wrapping paper and his face did not register any emotional change when the new toy - was revealed. Dee. at 75 (citing 4/25/2012 TR 904-07 (direct examination of Dr. Miller)).

In contrast, Petitioners’ expert, Dr. Shaf-rir, ended his specialized training in ASD in 2000 — well before the developments in the field Dr. Miller described. 4/23/2012 TR 525 (cross examination of Dr. Shafrir). Dr. Shaf-rir concluded “that the videos show no signs of ASD prior to November 10, 2001 and that the November 10 footage shows a dramatic overnight change compared to footage recorded the day before on November 9, 2001.” Dec. at 73. Dr. Shafrir testified that the change in AK.’s behavior between November 9 and 10, 2001 was “the most dramatic appearance of behavior change I’ve seen in my career.” 4/23/2012 TR 528. The Special Master, however, noted that “[Petitioners’ other experts did not appear to find the same significance in the November 9 and 10 videos.” Dec. at 76. A.K.’s parents also testified that they did not think A.K.’s behavior change between November 9 and 10 was dramatic. Dec. at 95. Moreover, one of Petitioners’ own experts who submitted a report, Dr. Mary N. Megson, corroborated Dr. Miller’s conclusion and contradicted Dr. Shafrir’s. Dec. at 79. Specifically, in her report, Dr. Megson wrote, “from 16-24 months of age, [A.K.] seem[ed] to plateau in his level of alertness and processing language.” Pet. Ex. 107, at 6. Dr. Kendall, another of Petitioners’ experts, observed that “A.K. demonstrated speech delay in the videos at 18 months of age[.]” Dee. at 88.

Based on this record, the Special Master concluded that “A.K. experienced ... a gradual manifestation of ASD which could be observed long before he was administered either of the two doses of influenza vaccine in ... 2001.” Dec. at 94-95. In reaching this conclusion, the Special Master found that “Dr. Miller’s presentation regarding the proper screening and diagnosis for ASD is not only acceptable, it was in fact far more extensive, better supported, and far more credible than Dr. Shafrir’s testimony on the same topics.” Dec. at 70.

Third, the Special Master addressed Petitioners’ theories of causation. Petitioners argued that “A.K.[’s] mitochondrial defect renders him particularly susceptible to oxidative stress, which was activated by the two doses of trivalent influenza vaccine, thereby causing his decompensation and severe developmental regression.” Pet. PH at 4. To support them argument, Petitioners offered two different theories of causation.

First, Dr. Kendall testified that A.K.’s mitochondrial disorder could induce “periods of decompensation or deterioration];.]” Dec. at 97 (citing Pet. Ex. 65, at 7). The influenza vaccinations aggravated the mitochondrial disorder, resulting in developmental regression. Dec. at 97 (citing Pet. Ex. 65, at 8). The Special Master noted, however, that “[t]he evidence that mitochondrial deterioration can be linked ... to vaccines is largely anecdotal, and the evidence that mitochondrial decompensation looks like ASD is nearly non-existent.” Dec. at 97. In particular, the Special Master criticized Dr. Kendall’s reliance on an article about Poling v. Sec’y of Health & Human Servs., 2008 WL 1883059 (Fed. Cl. Spec. Mstr. April 10, 2008). Dec. at 101. The Poling case report studied “a child who regressed after receiving vaccines at 19 months of age and who was subsequently diagnosed with both ASD and a mitochondrial disorder.” Dec. at 101. The Special Master surmised that “[t]he Poling case study is merely a single instance.... A single ease study in isolation is not significant proof[.]” Dec. at 107. Moreover, the Poling petitioner’s condition arose after receiving multiple vaccinations — none of which were for influenza. Dec. at 108-09. The Special Master also critiqued Dr. Kendall’s reliance on a paper by Dr. Shoffner. Dec. at 110. The Shoffner paper, however, “did not find that a vaccination was temporally associated with autistic regression in the absence of fever.” Dec. at 103 (citing 4/22/2013 TR 331-32). “[A]bsent an understanding of how or why fever can cause a mitochondrial deterioration, the conclusions one can draw from ,.. the Shoffner article are severely limited[.]” Dec. at 104.

Second, Dr. Shafrir posited a “triple hit” hypothesis — that “AK. had a mitochondrial disorder, a MTHFR polymorphism, and a genetically-determined abnormal immune system .,, which ... combined with his influenza vaccination, caused an autoimmune brain injury (encephalopathy) which manifested as an autistic regression.” Dec. at 111 (citing Pet. Ex. 63 at 14-18). The Special Master,' however, noted that Dr. Shafrir “failed to produce any evidence that A.K. had a brain injury caused by a vaccine reaction.” Dec. at 132. Moreover, Dr. Shafrir conceded that “he could not say that A.K.’s MTHFR polymorphisms caused A.K.’s autism[,]” Dec. at 120.

Third, Dr. Richard C. Deth testified in support of Dr. Kendall’s and Dr. Shafrir’s theories. Dr. Deth concluded that “vaccinations promote inflammation and oxidative stress[J” Dec. at 133 (quoting 4/24/2013 TR 751). The Special Master, however, did not find Dr. Deth to be credible. Dec. at 133. This is because Dr. Deth “failed to mention that data he was presenting was potentially contradicted by other findings within the same study.” Dec. at 150.

Having considered Petitioners’ expert witnesses, the Special Master proceeded to apply the three-part test articulated in Althen, 418 F.3d at 1278. Dec. at 157. Althen requires a petitioner in an off-Table causation case to provide: “a medical theory causally connecting the vaccination and injury; a logical sequence of cause and effect ...; and ... a proximate temporal relationship between vaccination and injury.” Althen, 418 F.3d at 1278.

For the first AUhen element, the Special Master found that while “ ‘[mjitochondrial autism’ may someday be accepted as a descriptor for co-morbid autism and mitochondrial disorder diagnoses ... there is little evidence that autism itself is caused by such disorder, and no evidence that autism causes mitochondrial disorders.” Dec. at 157. The Special Master also found that Dr. Kendall’s theory is “completely unsupported by any scientific literature.” Dec, at 157. Moreover, Dr. Shafrir “failed to articulate any basis for claiming that an influenza vaccination could lead, via autoimmunity, to the type of injury A.K. experienced.” Dec. at 157. In addition, the Special Master found that “Doctor Deth’s opinion suffered far too many serious flaws to be credited.” Dec. at 158. Here, the Special Master noted that “Dr. Deth acknowledged that not all oxidative stress is injurious ... [and] conceded that he could not opine what level of oxidative stress is created by a vaccination or what level of oxidative stress would be necessary to cause the type of neurological injury he described.” Dec. at 158.

For the second and third AUhen elements, the Special Master found that there was not a logical sequence of cause and effect between the vaccination and injury or proximate temporal connection, because “there is strong evidence in the record suggesting that A.K.’s condition predated his vaccinations.” Dec. at 158.

E. Petitioners’ October 28, 2015 Motion For Review.

1. Petitioners’ Objections.

Petitioners’ October 20, 2015 Motion includes a constitutional claim and twelve objections to the Special Master’s September 28, 2015 Decision that are summarized as follows: 1) the amendment of the Vaccine Act is unconstitutional; 2) the Special Master’s determination that A.K.’s ASD predated the influenza vaccinations was arbitrary and capricious; 3) the Special Master’s determination that A.K. did not have an underlying mitochondrial disorder was arbitrary and capricious; 4) the Special Master misapplied AUhen to Petitioners’ causation theories; 5) the Special Master improperly denied Petitioners’ Motion For Judicial Estoppel; and 6) the Special Master improperly denied Petitioners’ Motion To Exclude.

Petitioners first argue that Congress cannot bar common law litigants from access to Article III courts. Pet. Mem. at 3 (citing Stern v. Marshall, 564 U.S. 642, 131 S.Ct. 2594, 2615, 180 L.Ed.2d 475 (2011) (“The ‘experts’ in the federal system at resolving common law counterclaims ... are the Article III courts[.]”). Because the Vaccine Act denies Petitioners access to an Article III court, the Vaccine Act is unconstitutional and denies due process of law. Pet. Mem. at 3.

The Special Master’s determination that A.K.’s ASD predated the influenza vaccinations also was arbitrary and capricious, because the Special Master credited the Government’s expert witness, Dr. Miller, over Petitioners’ expert witness, Dr. Boris, who had “a far greater level of experience than Dr. Miller and had the advantage of treating [A.K.] over a long period of time[.]” Pet. Mem. at 7-8. Dr. Megson also was more qualified than Dr. Miller, because she is “a developmental pediatrician with over 40 years’ experience specializing in the treatment of autistic children, with the added qualification of being the mother of four children, three of whom are boys[.]” Pet. Mem. at 12. Because the Special Master relied on Dr. Miller instead of Petitioners’ superior expert witnesses, the Special Master’s conclusion was “unsupported by competent evidence.” Pet. Mem. at 15.

Next, Petitioners contend that the Special Master’s “conclusion that [A.K.] does not have mitochondrial disease is one that defies applicable law.” Pet. Mem. at 17. Mitochondrial disorder diagnosis lacks an objective diagnostic criteria. Pet. Mem. at 19. When “reasonable medical minds may legitimately differ ... [the United States Court of Appeals for] [t]he Federal Circuit's instruction set forth in Althen, 418 F.3d 1274 (Fed.Cir.2005) and Capizzano, 440 F.3d 1317, 1325 (Fed.Cir.2006) ... is to defer to the petitioners’ experts[.]” Pet. Mem. at 19.

In addition, the Special Master’s conclusion that Petitioners did not provide a reliable causation theory was error and the Special Master improperly raised Petitioners’ burden of proof. Pet. Mem. at 33, 38. In determining that the Petitioners’ experts did not establish how or why a fever can cause oxidative damage in conjunction with mitochondrial disease, the Special Master improperly raised the burden of proof to beyond a preponderance of evidence standard. Pet. Mem. at 39.

Petitioners add that the Special Master erred in denying Petitioners’ Motion to estop the Government from denying that a vaccination creates sufficient stress to cause autism in a child with mitochondrial disorder. Pet. Mem. at 56. Specifically, in Poling, 2008 WL 1883059, the Government filed a Rule 4 Report, conceding that “the facts of this ease meet the statutory criteria for demonstrating that the vaccination ... received on July 19, 2000, significantly aggravated an underlying mitochondrial disorder, which ... manifested as a regressive encephalopathy with features of [ASD].” Poling, 2008 WL 1883059, at *1. Therefore, the Government should have been estopped from arguing otherwise here. Pet. Mem. at 57.

Finally, the Special Master’s denial of Petitioner’s Motion To Exclude The Testimony Of Dr. Miller was in error. Pet. Mem. at 57.

2. The Government’s Response.

The Government did not respond to Petitioners’ constitutional argument; but defended the Special Master’s determination that A.K.’s ASD predated the influenza vaccination was not arbitrary or capricious. Gov’t Mem. at 12. It is within a Special Master’s purview to weigh expert testimony. Gov’t Mem. at 13 (citing Moberly v. Sec’y of Health & Human Servs., 592 F.3d 1315, 1325 (Fed.Cir.2010) (“Weighing the persuasiveness of particular evidence often requires a finder of fact to assess the reliability of testimony, including expert testimony, and we have made clear that the [S]peeial [M]asters have that responsibility in Vaccine Act eases.”). The Special Master’s decision that Dr. Miller was more credible than Petitioners’ experts is supported by evidence. Gov’t Mem. at 13. Dr. Miller has more publications on ASD than Petitioners’ experts. Gov’t Mem. at 13. Dr. Miller also has experience diagnosing ASD, as well as teaching others how to diagnose ASD. Gov’t Mem. at 13. Moreover, “the Special Master was clear that while she afforded Dr. Miller’s opinion substantial weight, her determination was based on the totality of evidence!.]” Gov’t Mem. at 15. “The Special Master also pointed out that two of petitioners’ experts, Dr. Megson and Dr. Kendall essentially confirmed that AK. showed symptoms of his ASD months before vaccinations.” Gov’t Mem. at 15 (citing Dec. at 79, 88).

The Government argues that the Special Master “did not err in finding that A.K. does not have a mitochondrial disorder!,]” because the Special Master’s determination is supported by the record. Gov’t Mem. at 19. The Special Master found Dr. Kendall’s testimony unreliable, because Dr. Kendall, when cross examined, did not defend her position that A.K. definitively had mitochondrial dysfunction. Gov’t Mem. at 21. The Special Master evaluated and analyzed the evidence under the Bernier criteria and is reasoned and factually supported. Gov’t Mem. at 21.

In addition, Petitioners’ reading of Althen and Capizanno is incorrect. Gov’t Mem. at 23. The Special Master is not required to defer to any of the experts nor notations in the record. Gov’t Mem. at 23. Instead, “it was her duty to evaluate the entire evidentia-ry record, make findings of a fact, and reach a conclusion ... in light of the record as a whole.” Gov’t Mem. at 23 (citing Sword v. United States, 44 Fed.Cl. 183, 188 (1999) (“Expert opinion is just opinion, and the fact-finder may weigh and assess that opinion in coming to her own conclusions.... [T]his [c]ourt has recognized the unique ability of Special Masters to adjudge eases in light of their own acquired specialized knowledge and expertise!.]”).

Likewise, the Special Master’s determination that Petitioners’ causation theories were unreliable was in accordance with the law. Gov’t Mem. at 24. The Special Master thoroughly evaluated, but rejected two pieces of evidence on which Dr. Kendall relied to support her causation theory. Gov’t Mem. at 26. The Special Master also properly rejected the Poling ease study and Dr. Shoffner’s article. Gov’t Mem. at 26. The Special Master’s determination that Petitioners’ expert witness, Dr. Deth, was not credible is “wholly within the Special Master’s charge.” Gov’t Mem. at 29 (citing Lampe v. Sec’y of Health & Human Servs., 219 F.3d 1357, 1362 (Fed.Cir.2000) (stating that a Special Master’s “assessments of the credibility of witnesses and the relative persuasiveness of the competing medical theories of the ease ... are virtually unchallengeable on appeal[.]”).

The Special Master also correctly denied Petitioners’ Motion For Estoppel and Motion To Exclude. Gov’t Mot. at 33. In the Ruling On Motions, the Special Master provided four reasons for rejecting judicial estoppel:

(1) Judicial estoppel does not apply when a case has been settled; (2) petitioners failed to satisfy the three requirements for the invocation of judicial estoppel; (3) decisions issued by special masters and judges at the [United States] Court- of Federal Claims are not binding; and (4) a concession by respondent in one case does not constitute a concession in another.

Gov’t Mem. at 33 (citing Ruling at 36-37).

With respeet to Petitioners’ Motion To Exclude, the Special Master found Dr. Miller qualified to testify, but “noted that any deficiencies in ... Dr. Miller’s testimony ‘are more appropriately addressed in the assignment of weight to her testimony rather than its wholescale exclusion.’” Gov’t Mem. at-33-34 (quoting Ruling at 54).

3. The Court’s Resolution.

a. The Constitutional Issue.

As a threshold matter, the Vaccine Act is constitutional, because the Vaccine Act categorically does not deny access to Article III courts. In fact, Petitioners may appeal this decision to the United States Court of Appeals for the Federal Circuit. See 42 U.S.C. § 300aa-12(f) (“[A]ny petitioner aggrieved by the findings or conclusions of the [United States Court of Federal Claims] may obtain review of the judgment of the court in the United States Court of Appeals for the Federal Cireuit[.]”). In addition, Petitioners have misread Stem’s holding that Article I bankruptcy courts do not have jurisdiction oyer common law claims between private parties. See Stern, 131 S.Ct. at 2614-15 (recognizing that the claim at issue was “one under state common law between two private parties.... The ‘experts’ in the federal system at resolving common law counterclaims ... are the Article III courts[.]”). The claims in this case, are alleged against the Government rather than a private party. Moreover, Stem has been limited by the United States Supreme Court’s recent decision in Wellness Int’l Network, Ltd. v. Sharif, — U.S. —, 135 S.Ct. 1932, 1944, 191 L.Ed.2d 911 (2015) that held, “allowing Article I adjudicators to decide claims submitted to them by consent does not offend the separation of powers so long as Article III courts retain supervisory authority over the process.”

b. The Merits.

As for the Special Master’s causation determination, the first element of Althen requires “a medical theory causally connecting the vaccination and the injury[.]” Id. at 1278. The Special Master found that Petitioners did not satisfy the first element in concluding that Dr. Kendall’s causation theory was “unsupported by any scientific literature.” Dec. at 157. The United States Court of Appeals for the Federal Circuit has held that requiring general acceptance by the scientific community or requiring medical literature impermissibly raises the preponderance of the evidence standard. See Althen, 418 F.3d at 1281 (“[T]he Vaccine Act does not require Althen [the .petitioner] to provide medical documentation of plausibility[.]”).

The second element requires “a logical sequence of cause and effect showing that the vaccination was the reason for the injury[.]” Id. at 1278. The third element requires “a proximate temporal relationship^]” Id. Here, the Special Master properly determined that Petitioners failed to establish the second and third elements, because A.K. showed “signs of both ASD and speech delay well before receiving ... influenza vaccinations.” Dec. at 158. Therefore, the Special Master determined that there was not a logical sequence, because “the actual timeline of events do not support [P]etitioners’ claim of a regression.” Dec. at 158. Although the Special Master misapplied the first element, the correct application of the second and third elements is dispositive as to causation.

The Special Master’s determination that A.K.’s ASD predated the influenza vaccinations was not arbitrary and capricious. It is clear from the September 28, 2015 Decision that the Special Master based findings of fact about this issue by weighing the credibility of both parties’ experts, analyzing medical records and related evidence, and personally viewing the home videos of A.K. Dec. at 68-96.

Likewise, the Special Master’s determination that A.K. did not have an underlying mitochondrial disorder is not arbitrary and capricious, because as the fact-finder, the Special Master may assess “the credibility of the witnesses and the relative persuasiveness of the competing medical theories of the case.” Lampe, 219 F.3d at 1362.

As to this issue, Petitioners had the burden to establish that A.K. had a mitochondrial disorder, but as the Special Master’s decision states, did not meet a preponderance of evidence standard. See Althen, 418 F.3d at 1278 (“[Petitioner] sought redress ... for off-Table injury. [Petitioner] must prove by a preponderance of the evidence that the [] vaccination caused her malady.”); see also Capizzano, 440 F.3d at 1320 (“In [an off-Table injury] case, the petitioner must prove by a preponderance of the evidence that the vaccine at issue caused the injury.”). In this case, the Special Master carefully considered the testimony of Petitioners’ expert, Dr. Kendall. Dec. at 49. In addition, the Special Master took into consideration that, on cross examination, Dr. Kendall contradicted her report by conceding that she could not conclude that A.K. definitively had mitochondrial disorder. 4/22/2013 TR 319. The Special Master also examined A.K.’s lab results and medical literature proffered. Dec. at 54-68. Therefore, the Special Master “considered the relevant evidence of record, [drew] plausible inferences, and articulated a rational basis for the decision.” Lampe, 219 F.3d at 1360 (internal quotations omitted). As such, it is not for the court “to reweigh the factual evidence, or to assess whether the [S]peeial [M]aster correctly evaluated the evidence. And of course we do not examine the probative value of the evidence or the credibility of the witnesses. These are all matters within the purview of the fact finder.” Munn, 970 F.2d at 871.

c. Judicial Estoppel.

Judicial estoppel “generally prevents a party from prevailing in one phase of a ease on an ai’gument and then relying on a contradictory argument to prevail in another phase.” New Hampshire v. Maine, 532 U.S. 742, 749, 121 S.Ct. 1808, 149 L.Ed.2d 968 (2001) (internal quotations omitted). Three factors inform whether judicial estoppel applies:

[A] party’s later position must be ‘clearly-inconsistent’ with its earlier position.... Second, courts regularly inquire whether the party has succeeded in persuading a court to accept that party’s earlier posi-tion_ Absent success in a prior proceeding, a party’s later inconsistent position introduces no ‘risk of inconsistent court determinations....’ A third consideration is whether the' party seeking to assert an inconsistent position would derive an unfair advantage^]

Id. at 750-51, 121 S.Ct. 1808 (internal citations omitted).

In the September 28, 2015 Ruling On Motions, the Special Master applied the New Hampshire factors in denying Petitioners’ Motion For Judicial Estoppel. First, the Special Master determined that the Government’s position in this case was “not ‘clearly inconsistent’ ” with its position in Poling. Ruling at 36. “In Poling, [the Government’s] position was that the child had sustained a Table injury ... and thus presumptively should be compensated. Here, there is no allegation that A.K. suffered a Table injury within the requisite time period.” Ruling at 36. The Special Master also determined that there was no risk of inconsistent court determinations, because “Special [M]asters are neither bound by their own decisions nor by cases from the [United States] Court of Federal Claims, except, of course, in the same case on remand.” Ruling at 36. Finally, the Special Master determined that Petitioners were not at an unfair disadvantage, because the Government’s position in Poling and this case are not inconsistent. Ruling at 37.

Specifically, in Poling, the “vaccinations Hannah received on July 19, 2000, significantly aggravated an underlying mitochondrial disorder, which predisposed her to deficits in cellular energy metabolism, and manifested as a regressive encephalopathy with features of [ASD].” Rule 4(c) Report at 7, Poling ex rel. Poling v. Sec’y of Health & Human Servs., No. 02-1466 V, 2008 WL 1883059 (Fed.Cl.Spec.Mstr. Apr. 10, 2008). The vaccinations at issue there were DTaP, Hib, MMR, Varivax, and IPV. Rule 4(c) Report at 2, Poling ex rel. Poling v. Sec’y of Health & Human Servs., No. 02-1466 V, 2008 WL 1883059 (Fed.Cl.Spec.Mstr. Apr. 10, 2008). But the vaccinations in this case are influenza vaccinations. As such, the Government did not assert an inconsistent position that triggers judicial estoppel,

d. Abuse Of Discretion.

With respect to the Special Master’s denial of Petitioner’s Motion To Exclude Dr. Miller’s Testimony, the court applies an abuse of discretion standard. See Munn, 970 F.2d at 870 n. 10 (“[Discretionary rulings [are reviewed] under the abuse of discretion standard. The latter will rarely come into play except where the [S]peeial [M]aster excludes evidence.”). To find an abuse of discretion, the court must determine that the Special Master’s decision was “(1) ... clearly unreasonable, arbitrary, or fanciful; (2) ... based on an erroneous conclusion of the law; (3) ... clearly erroneous; or (4) the record contains no evidence on which the ... [Special Master] rationally could have based his decision.” Hendler v. United States, 952 F.2d 1364, 1380 (Fed.Cir.1991). An abuse of discretion generally does not occur where a Special Master “considered the relevant evidence, drew plausible inferences, and articulated a rational basis for his finding[.]” Masias v. Sec’y of Health & Human Servs., 634 F.3d 1283, 1290 (Fed.Cir.2011).

The Special Master in this case considered Dr. Miller’s experience at the Children’s Hospital of Philadelphia in the Center for Autism Research. 4/25/2013 TR 847. The Special Master also considered the Government’s other witness, Dr. Bruce Cohen, who corroborated Dr. Miller’s testimony. Ruling at 54. In addition, the Special Master found that Dr. Miller had “more publications on the topic of ASD than any of [Petitioners’ own experts.” Ruling at 54. Therefore, since the Special Master’s decision was supported, there was no abuse of discretion.

IV. CONCLUSION.
