UNITED STATES COURT OF APPEALS FOR VETERANS CLAIMS

NO. 09-3525

RICK K. KAHANA, APPELLANT,

V.

ERIC K. SHINSEKI,

SECRETARY OF VETERANS AFFAIRS, APPELLEE.

On Appeal from the Board of Veterans' Appeals

(Decided June 15, 2011)

Sandra W. Wischow, of Richmond, Virginia, was on the brief for the appellant.

Will A. Gunn, General Counsel; R. Randall Campbell, Assistant General Counsel; Nisha C.

Wagle, Acting DeputyAssistant General Counsel; and Thomas E. Sullivan, all of Washington, D.C.,

were on the brief for the appellee.

Before MOORMAN, LANCE, and SCHOELEN, Judges.

SCHOELEN, Judge, filed the opinion of the Court. LANCE, Judge, filed an opinion

concurring in the result.

SCHOELEN, Judge: The appellant, Rick K. Kahana, appeals through counsel the portion

of an August 10, 2009, Board of Veterans' Appeals (Board) decision that denied him entitlement to

service connection for a right knee disability including as secondary to a service-connected left knee

disability. Record of Proceedings (R.) at 3-17. This appeal is timely, and the Court has jurisdiction 1

to review the Board's decision pursuant to 38 U.S.C. §§ 7252(a) and 7266(a). The question before

the panel is whether the Board's findings concerning the credibility of the appellant's lay statements

The Board, in the same decision, granted the appellant service connection for a low back 1

disability. The Board noted that "some level of back problem in service as a result of his kickboxing

activities is not unreasonable" and relied on a December 2008 VA examiner, who found that it was

as likely as not that the appellant's low back disability was related to these falls in service. Record

of Proceedings (R.) at 14.
conflict with the Court's holding in Colvin v. Derwinski, 1 Vet.App. 171 (1991). Because the Court

holds that the Board erred in making a medical determination concerning the severity of an anterior

cruciate ligament (ACL) in violation of Colvin, the Court will vacate the portion of the Board's

decision denying the appellant entitlement to service connection for a right knee disability and

remand the matter for further proceedings consistent with this opinion.

I. BACKGROUND

A. Facts

The appellant served on active duty in the U.S. Army from September 1976 until September

1979. R. at 737. The appellant's service medical records (SMRs) and service separation report of

medical history include extensive references to in-service injuries to his left knee. R. at 613-708,

613-15. There is no reference to an injury to the right knee in the appellant's service separation

report. Id. By March 1980, the appellant had been granted service connection for his left knee 2

injuries. R. at 603. 

In April 1993, Dr. Frederick G. Nicola, the appellant's private orthopedist, performed

arthroscopic surgery and an ACLreconstruction on the appellant's right knee. R. at 262. According 3

to the records of Dr. Sam Bakshian, the appellant's left ACL was surgically repaired for the first time

in the early 1990s. R. at 558. Dr. Bakshian also reported that the appellant injured his back and both

knees in 1995 while performing as a stuntman. R. at 509. Dr. Nicola subsequently performed a

In the decision here on appeal, the Board found that there is no evidence of a right knee 2

injury in the appellant's SMRs. R. at 14. The Court notes that the record contains a May 16, 1978,

clinical record, which reported "effusion sighted r[ight] patella" and increased pain on palpation and

on leg lift of the medial and lateral meniscus regions and a limited range of motion. R. at 634. The

appellant makes no reference to this record cite and does not specifically dispute the Board's finding

of no SMR evidence of a right knee injury in service. Nevertheless, the appellant maintains that he

injured his right knee in service while participating in a Tae Kwon Do match in Korea and did seek

medical attention at that time and was told it was "just a sprain." Appellant's Brief at 10. 

The April 1993 date for the appellant's right knee surgery performed by Dr. Nicola was

3

recorded in a clinical record. According to the appellant's medical history contained in a VA medical

examination report, the first surgical repair of a right ACL tear occurred in 1994. R. at 58. In

January 2002, Dr. Nicola confirmed that he had performed a right ACL reconstruction on the

appellant, but did not indicate the date. R. at 578.

2
 bilateral ACL reconstruction. Id. 

The appellant was provided a hearing before the Board in September 2007. R. at 306-26. 

There, he stated that he injured his right knee in service, and was unsure why the injury did not 

appear in his SMRs. R. at 311. He related that his original left knee injury was not fixed properly,

and that led him to put too much pressure on his right leg so that when he was in a kickboxing

competition in 1978 in Korea he "got kicked" and "got knocked down" and the right knee "snapped."

R. at 311, 321. The appellant said "it was another ACL injury." R. at 321. The appellant also

reported that he sustained an additional injury to his right knee following service, but attributed both

the in-service and postservice injuries to the fact that he continually favored his left leg. R. at 325.

Following the appellant's hearing, in November 2007, the Board remanded the matter for

additional development, which included providing the appellant with a VA medical examination "to

determine the likely etiology of [his] current right knee . . . disabilit[y]." R. at 300-05. The Board

noted: 

The veteran has not received a VA examination to specificallyevaluate whetherthere

is a relationship between his right knee . . . disabilit[y] and his military service. . . . 

As he has made reasonable allegationsregarding the presence of such a relationship,

the Board finds that such a VA examination is warranted prior to final adjudication

of his claim. 

R. at 302 (emphasis added).

In a December 2008 VA examination report, the examiner recorded the appellant's assertions

that his right knee snapped during an in-service kickboxing competition. R. at 58. The appellant

stated that he was seen at a clinic and was told he had only sustained a sprain. Id. He related that

he continued to have problems following his discharge, and was eventually diagnosed with a right

ACL tear that required surgical repair in the 1990s. Id. 

The examiner concluded that the appellant injured his right knee while in service in 1979,

but noted that the appellant did not seek treatment until the 1990s. R. at 73-74. The examiner also

concluded that the appellant's right knee injury resulted from his habit of putting more weight on his

right knee after numerous left knee injuries. R. at 74. In reaching her conclusions, the examiner

reviewed private medical records, but did not review SMRS or VA records, and stated that she based

her opinion on the history given by the appellant and the records of Dr. Nicola. Id. 

3
VA requested that the claims folder be returned to the examiner who completed the

December 2008 examination for "addendum, opinion[,] and r[a]tionale for opinion." R. at 54. 

Further instructions on the request stated:

Examination report states SMR[]s NOT reviewe[d].[Social SecurityAdministration]

records show [appellant] sustained injuries in 1994 secondaryto work as a stuntman. 

No right knee injury in service. Injuries sustained post-service were not discussed.

Id. 

Subsequently, in a March 2009 VA examination report, the same examiner who had

performed the 2008 examination noted that the appellant reported an in-service injury to his right

knee, but that there was no documentation in his SMRs of a right knee injury. R. at 47-48. The

examiner concluded that the appellant's right knee injury is not related to his military service. R. at

48. As rationale for her decision, the examiner stated that "[t]here is no documentation of right knee

injury in the [appellant's SMRs] to support [his] claim." R. at 48-49. The examiner, discussing the

appellant's private medical records, noted that, while Dr. Nicola's letter indicates an in-service right

knee injury, records from Dr. Sam Bakshian indicate that the appellant's right knee ACL tear was

from a 1994 work-related injury. R. at 48. The examiner furtherfound that the appellant's right knee

condition "is not felt to be caused by or related to" his left knee condition. R. at 49. As rationale,

the examiner stated that the appellant's injury, an ACL ligament sprain, "resulted from a specific

trauma incident and is not an overuse type of injury. Medical records reviewed did not support that

a right knee injury occurred during the [appellant's] service but rather was a work-related injury." 

Id. 

The Board, in its August 10, 2009, decision here on appeal, denied the appellant entitlement

to service connection for a right knee disability including as secondary to a service-connected left

knee disability. The Board noted that the appellant's SMRs show that he injured his left knee while

in service but do not show that he injured his right knee. R. at 14. The Board then found that the

appellant's assertion that he tore his right ACL during service was not credible. R. at 14-15. The

Board also found that the appellant was not competent to "provide an opinion regarding medical

nexus." R. at 16. The Board found that the evidence failed to establish any continuity of

symptomatology in his right knee after service, and the lengthy gap between his service and the first

evidence of a right knee disorder in 1993 is "a factor against a finding that the disability was incurred

4
or aggravated in service." Id. 

Regarding the March 2009 VA medical opinion, the Board found that it "provides specific

probative evidence weighing against a finding that the [appellant's] current right knee disability is

related to service or that it was caused or aggravated by the [appellant's] service[-]connected left

knee disability." R. at 16. 

B. Arguments on Appeal

The appellant argues that the Board made an improper medical finding based on the nature

of his claimed injury when it found that, had the appellant sustained such an injury in service, it

would have required treatment and thus should have appeared in his SMRs. Appellant's Brief (Br.)

at 8-9. The appellant also contends that VA, when it requested a revised medical opinion,

improperly impinged on the examiner's impartiality by stating to the examiner that the appellant had

sustained no right knee injury in service. Id. at 11-13. Finally, the appellant argues that the Board

failed to provide an adequate statement of reasons or bases for its decision because it rejected his lay

testimony based on a lack of supporting medical records and that the revised medical opinion is

inadequate because it is based on an inaccurate factual premise. Id. at 8-9, 13-17.

The Secretary argues that the Board's finding that the appellant's injury should have required

medical treatment was not an improper medical finding, but permissible as an "inference based on

the evidence." Secretary's Br. at 12. The Secretary also asserts that the VA examiner, in her first

opinion, relied only on medical history as provided by the appellant and private medical records. 

Id. at 14. Her opinion changed, the Secretary contends, after reviewing other evidence found in the

claims file. Id. The Secretary further argues that VA asked for a revised opinion for a number of

reasons, and that the Agency did nothing to solicit or predetermine the outcome of the examination. 

Id. at 15-16. The outcome of the revised examination, the Secretary argues, was a reflection of the

evidence of record and not tainted by bias or impartiality. Id. at 16-17.

II. ANALYSIS

Establishing service connection generally requires medical or, in certain circumstances, lay

evidence of (1) a current disability; (2) incurrence or aggravation of a disease or injury in service;

and (3) a nexus between the claimed in-service injury or disease and the current disability. See

5
Davidson v. Shinseki, 581 F.3d 1313, 1316 (Fed. Cir. 2009); Hickson v. West, 12 Vet.App. 247, 252

(1999); Caluza v. Brown, 7 Vet.App. 498, 506 (1995), aff'd per curiam, 78 F.3d 604 (Fed. Cir. 1996)

(table). A finding of service connection is a finding of fact that the Court reviews under the "clearly

erroneous" standard of review. See Dyment v. West, 13 Vet.App. 141, 144 (1999).

When deciding a matter, the Board must include in its decision a written statement of the

reasons or bases for its findings and conclusions, adequate to enable an appellant to understand the

precise basis for the Board's decision as well as to facilitate review in this Court. See 38 U.S.C.

§ 7104(d)(1); Allday v. Brown, 7 Vet.App. 517, 527 (1995); Gilbert v. Derwinski, 1 Vet.App. 49,

56-57 (1990). To complywith this requirement, the Board must analyze the credibilityand probative

value of the evidence, account for the evidence that it finds persuasive or unpersuasive, and provide

the reasons for its rejection of any material evidence favorable to the claimant. See Caluza,

7 Vet.App. at 506; Gilbert, 1 Vet.App. at 57. 

A. Lay Testimony4

The Board, in its role as factfinder, "is obligated to, and fully justified in, determining

We generallyagree with our colleague that too often the Board makes overbroad categorical

4

statements regarding the competency and credibility of lay testimony. However, our disagreement

with our colleague's commentary on the proper evaluation of lay evidence starts at its base. Where

our colleague begins with the general proposition that lay witnesses generally are not competent to

provide evidence on matters that require medical expertise, we understand the Federal Circuit's

direction in this area to begin with the basic premise that "in the veterans' context, traditional

requirements for admissibility have been relaxed." Jandreau v. Nicholson, 492 F.3d 1372, 1377

(Fed. Cir. 2007). Thus, the Federal Circuit has flatly rejected the view that "competent medical

evidence is required . . . [when] the determinative issue involves either medical etiology or a medical

diagnosis." Id. at 1376-77 (emphasis added). The Board is required to consider "all pertinent

medical and lay evidence." 38 U.S.C. § 1154(a); see also 38 U.S.C. § 5107(b); 38 C.F.R. §§

3.303(a), 3.307(b) (2010). When considering such lay evidence, the Board should determine, on a

case-to-case basis, whether the veteran's particular disability is the type of disability for which lay

evidence is competent. See Jandreau, 492 F.3d at 1376-77 (cited in Robinson v. Shinseki,

312 F. App'x. 336, 339, No. 2008-7096, 2009 WL 524737, at *2-3 (Fed. Cir. Mar. 3, 2009)

(remanding the matter for consideration of the appellant's lay evidence, which requires a "two-step

analysis" that begins with an evaluation of whether the veteran's disability is the type of injury for

which lay evidence is competent)). If the disability is of the type for which lay evidence is

competent, the Board must weigh that evidence against the other evidence of record in making its

determinations regarding the existence of service connection. See Buchanan v. Nicholson, 451 F.3d

1331, 1336-37 (Fed. Cir. 2006). 

6
whether lay evidence is credible in and of itself." Buchanan, 451 F.3d at 1337 (emphasis added). 

Also, a layperson may be competent "to establish a diagnosis of a condition when (1) a layperson

is competent to identify the medical condition, (2) the layperson is reporting a contemporaneous

medical diagnosis, or (3) lay testimony describing symptoms at the time supports a later diagnosis

by a medical professional." Jandreau, 492 F.3d at 1377 (footnote omitted). The Board rejected the

appellant's lay statements based both on credibility and competency.

1. Credibility

In finding that the appellant's statements lack credibility, the Board stated:

Given that a right ACL tear is quite a significant injury, one would expect to see at

least some documentation of it in the [SMRs]. Also, one would expect that the

[appellant] would have mentioned this right knee injury on his report of medical

history at separation[,] but instead this document shows only that the [appellant]

reported two separate injuries to the left knee. In addition[,] the Board notes that

when the [appellant] initially filed his claim, he did not allege a right knee injury in

service. Instead he alleged only that he incurred a left knee injury and that his right

knee disability was secondary to that injury. The [appellant] then made similar

contentions in his Notice of Disagreement. For all of these reasons, the Board does

not find his more recent assertions of right knee injury in service credible.

R. at 15. 

Regarding the Board's statement that, given the nature of the appellant's injury, some

documentation in his SMRs is expected, the Court agrees with the appellant's argument that the

Board violated the Court's holding in Colvin, supra. Appellant's Br. at 8-9. In Colvin, the Court 5

held that the Board "must consider onlyindependent medical evidence to support [its]findings rather

than provide [its] own medical judgment in the guise of a Board opinion." 1 Vet.App. at 172. 

Requiring the Board to support its medical determinations with independent medical evidence

"ensures that all medical evidence contrary to the veteran's claim will be made known to him and be

a part of the record before this Court." Id. at 175. In this case, the Board is making a medical

determination as to the relative severity, common symptomatology, and usual treatment of an ACL

injury without citing to any independent medical evidence to corroborate its finding. Indeed, the

In his separate statement, our colleague is in agreement with this stated Colvin violation and 5

the reasoning of the majority that follows on this point. 

7
record is devoid of any medical evidence establishing the relative severity, common

symptomatology, and usual treatment of an ACL injury. Therefore, the Court holds that the Board

clearly erred when it found the appellant not to be credible based on its determination that a

particular injury, which is alleged to have occurred in service, is of the type that should have been

documented in the service records and was not.

The Secretary argues that the Board was drawing a permissible "inference based on the

evidence." Secretary's Br. at 12. Drawing an "inference based on the evidence" is at the heart of any

adjudication. However, under Colvin, when a Board inference results in a medical determination,

the basis for that inference must be independent and it must be cited. The Court thus finds that the

Board has violated Colvin, and its statement of reasons or bases for its determination that the

appellant's lay statements lack credibility is inadequate. See 38 U.S.C. § 7104(d)(1); Allday, Caluza,

and Gilbert, all supra. Therefore, in considering the matter on remand, the Board must reassess the

weight and credibility of the appellant's lay statements and adequately explain any negative

credibility determination. See Washington v. Nicholson, 19 Vet.App. 362, 367-68 (2005) (it is the

Board's responsibility, as factfinder, to determine the credibility and weight to be given to the

evidence). 

2. Competency

The Board, in rejecting the appellant's lay statements based on competency, found that he

"does contend that his current right knee disability is related to service and to his service-connected

left knee disability, [but] as a layperson he is not competent to provide an opinion regarding medical

nexus." R. at 16. This finding is legally unsupportable. This Court has held that "[l]ay testimony

is competent . . . to establish the presence of observable symptomatology and 'may provide sufficient

support for a claim of service connection.'" Barr v. Nicholson, 21 Vet.App. 303, 307 (2007) (quoting

Layno v. Brown, 6 Vet.App. 465, 469 (1994)); see also Jandreau, supra; Charles v. Principi,

16 Vet.App. 370, 374 (2002) (stating that a layperson is competent to offer testimony regarding

symptoms capable of observation). And, as stated earlier, there is no categorical requirement of

"'competent medical evidence . . . [when] the determinative issue involves either medical etiology

or a medical diagnosis.'" Davidson, 581 F.3d at 1316 (quoting Jandreau, 492 F.3d at 1377). As a

result, the Court concludes that the Board's categorical rejection and failure to analyze and weigh the

8
appellant's lay evidence in accordance with established precedent renders its statement of reasons

or bases inadequate. See 38 U.S.C. § 7104(d)(1); Allday, Caluza, and Gilbert, all supra. 

B. December 2008 and March 2009 VA Medical Examinations

The Secretary's duty to assist includes "providing a medical examination or obtaining a

medical opinion when such an examination or opinion is necessaryto make a decision on the claim."

38 U.S.C. § 5103A(d)(1); see also Green v. Derwinski, 1 Vet.App. 121, 124 (1991). This Court has

held that a medical opinion is adequate "where it is based on consideration of the veteran's prior

medical history and examinations and also describes the disability, if any, in sufficient detail so that

the Board's 'evaluation of the claimed disability will be a fully informed one.'" Stefl v. Nicholson,

21 Vet.App. 120, 123 (2007) (quoting Ardison v. Brown, 6 Vet.App. 405, 407 (1994)). 

In evaluating disability claims, the Board is obliged to reject insufficiently detailed medical

reports. 38 C.F.R. § 4.2 (2010) ("If a diagnosis is not supported by the findings on the examination

report or if the report does not contain sufficient detail, it is incumbent upon the rating board to

return the report as inadequate for evaluation purposes."). The appellant does not dispute VA's

authority to request the December 2008 VA examiner to clarify her opinion. Instead, the appellant

argues that the statement "[n]o right knee injury in service" (R. at 54) made by VA to the examiner

in its request for a revised report infringed upon VA's responsibility to observe the basic tenets of

fair play while gathering evidence. Appellant's Br. at 11. The appellant's argument relies on

precedent set in Austin v. Brown, 6 Vet.App. 547, 552 (1994), and a related line of cases.

In Austin, the Board's request for a medical opinion contained a sentence stating: "Clearly,

[the veteran's] in-service chest injury was not related to his fatal pulmonary emphysema." 6

Vet.App. at 549. The Court found that such a statement by the Board indicates that "there was no

process at work to ensure impartiality, and creates the impression that the Board was not securing

evidence to determine the correct outcome, but rather to support a predetermined outcome." Id. at

552. The Court held:

A [Board] decision which relies upon a [Board] medical adviser's opinion obtained

by a process that does not ensure an impartial opinion violates Thurber [v. Brown,

5 Vet.App. 119 (1993)]-type fair process. We hold that basic fair play requires that

evidence be procured by the agency in an impartial, unbiased, and neutral manner. 

The process employed here cannot be sustained as fair.

9
Id.; see also Bielby v. Brown, 7 Vet.App. 260, 268 (1994) (holding that VA must pose a hypothetical

question to an independent medical expert that "may not suggest an answer or limit the field of

inquiry of the expert," and reliance on an independent medical opinion where the Board constrained

the scope of inquiry is improper because such constraints resulted in "limiting [the examiner's]

investigation and tainting the results"); Colayong v. West, 12 Vet.App. 524, 535 (1999) (holding that

VA erred because the nature of its questions suggested an answer and impermissibly narrowed the

examiner's field of inquiry).

The Secretary attempts to distinguish Austin. Secretary's Br. at 15. He argues that, in Austin,

the Board "provided the answer to the examiner in advance of the examination," whereas in this case,

the Agency asked for a new opinion for a number of reasons, and thus the "[A]gency was not

soliciting a particular result, but pointing to the insufficiencies in the 2008 opinion." Id. at 15-16. 

The Court is not convinced. Despite the other reasons given to the examiner for a new opinion, the

request in this case was unequivocal in stating that there was "[n]o right knee injury in service." R. 6

at 54. This statement makes the matter at hand much like Austin, where VA made an explicit

statement of fact to an examiner that spoke to the crux of the examiner's opinion and of the case in

general. The Court also notes that at the time of the second examination request, there was no 7

adverse credibility determination concerning the appellant's lay assertions that he injured his right

knee in service. Contra Reonal v. Brown, 5 Vet.App. 458, 461 (1993) (holding that a medical

opinion based upon the appellant's account of his medical history and service background was of no

probative value where the recitations by the appellant had already been rejected bythe 1954 regional

office decision). The statement in this case directly contradicted the findings of the VA examiner

in her initial December 2008 opinion that the appellant injured his right knee in service. R. at 73. 

The Court notes that this statement by VA in the examination request was given even 6

though there is an SMR dated May 16, 1978, that appears to refer to an effusion of the right knee cap

with increased pain upon palpation of the meniscus regions and a limited range of motion. R. at 634. 

 We express no opinion now as to the circumstances under which it would be appropriate 7

for the Board to inform an examiner that a fact must be accepted as true. Such an opinion would

depend on the evidence (or medical evidence) presented in a particular case. Here, the statement by

the Board that there was no right knee injury in service was not supported by the record (see supra

note 6) and spoke to a crucial fact at issue for which a medical opinion was required.

10
The examiner subsequently reached the opposite conclusion in her March 2009 opinion – that the

appellant's right knee injury was not related to service. R. at 42. The Court is left unsure whether

the examiner revised her opinion based on additional evidence she reviewed or because she felt

coerced by the Agency's proclamation against her earlier conclusion. Therefore, the Court finds the

request violated the Board's duty to procure evidence in an "impartial, unbiased, and neutral

manner." Austin, 6 Vet.App. at 552; see also Bielby and Colayong, both supra. 

The Secretary further argues that since the SMRs show no right knee injury during service,

"there was no bias or impartiality in the addendum request." Secretary's Br. at 16. The Court does

not agree. As noted above, there appears to be one notation in the SMRs as to a right knee injury. 

R. at 634. In any event, the lack of medical evidence in service does not constitute substantive

negative evidence. McLendon v. Nicholson, 20 Vet.App. 79, 85 (2006). The examiner could have

potentially determined, based on other evidence of record including lay statements and private

medical opinions, that, regardless of the lack of documentation in the appellant's SMRs, the appellant

injured his right knee in service. The statement in the request that there was no right knee injury in

service indicated to the examiner that all of the evidence had already been analyzed and a conclusion

reached, and thus impeded her impartiality. On remand, the Board should procure an impartial

medical opinion on which to base its decision. In procuring an opinion, the Board is not precluded

from asking the physician (1) whether there is anymedical reason to accept or reject the proposition

that had the appellant had a right knee injury in service, such injury could have lead to his current

condition; (2) what types of symptoms would have been caused by the type of ACL injury at issue;

and (3) whether a right knee injury as described in the SMRs (R. at 634) could have been mistaken

for a sprain but was a precursor to the current condition.

Given this disposition, the Court will not, at this time, address the other arguments and issues

raised by the appellant. See Best v. Principi, 15 Vet.App. 18, 20 (2001) (per curiam order) (holding

that "[a] narrow decision preserves for the appellant an opportunity to argue those claimed errors

before the Board at the readjudication, and, of course, before this Court in an appeal, should the

Board rule against him"). On remand, the appellant is free to submit additional evidence and

argument on the remanded matters, and the Board is required to consider any such relevant evidence

and argument. See Kay v. Principi, 16 Vet.App. 529, 534 (2002) (stating that, on remand, the Board

11
must consider additional evidence and argument in assessing entitlement to benefit sought);

Kutscherousky v. West, 12 Vet.App. 369, 372-73 (1999) (per curiam order). The Court has held that

"[a] remand is meant to entail a critical examination of the justification for the decision." Fletcher

v. Derwinski, 1 Vet.App. 394, 397 (1991). The Board must proceed expeditiously, in accordance

with 38 U.S.C. § 7112 (requiring Secretary to provide for "expeditious treatment" of claims

remanded by the Court).

 III. CONCLUSION

After consideration of the appellant's and Secretary's pleadings, and a review of the record,

the portion of the Board's August 10, 2009, decision denying the appellant service connection for

a right knee disability is VACATED and the matter is REMANDED to the Board for further

proceedings consistent with this decision. 

LANCE, Judge, concurring: Although I agree with the result reached by my colleagues, I

am compelled to write separately because the issues involved arise so frequently as to justify

additional clarification. First, issues of witness credibility and competence are among the most

common raised to us and the distinctions between various cases are often misunderstood or

overlooked. Second, the proper relationship between the Board and VA medical experts is also an

area beset with confusion. This case presents an ideal fact pattern to do more than simply state what

the Board did wrong. Accordingly, I must address in greater detail how the Board should approach

these issues so that it may clearly articulate its analysis on these issues in the future.

I. THE RELATIONSHIP BETWEEN COMPETENCE AND CREDIBILITY

The first common issue that this case demonstrates is the often blurred line between

competence and credibility in the assignment of weight to lay testimony.

1. Lay Competence

In general, neither lay witnesses nor members of the Board are medical experts. Thus, the

beliefs of lay witnesses (including claimants) on issues of diagnosis and medical causation are not

competent evidence in situations where those issues require medical expertise to resolve. Compare

12
Jandreau v. Nicholson, 492 F.3d 1372, 1377 n.4 (Fed. Cir. 2007) (noting that a layperson is not

"competent" to diagnose a form of cancer), with Barr v. Nicholson, 21 Vet.App. 303, 309 (2007)

(holding that a layperson is competent to diagnose vericose veins). Similarly, in Colvin v.

Derwinski, the Court held that the Board "must consider only independent medical evidence to

support [its] findings rather than provide [its] own medical judgment in the guise of a Board

opinion." 1 Vet.App. at 171, 175 (1991); see also Maxson v. Gober, 230 F.3d 1330, 1333 (Fed. Cir.

2000) (holding that the Board is competent to consider "evidence of a prolonged period without

medical complaint, along with other factors" in determining that a condition was not aggravated by

service). The question of whether a particular medical issue is beyond the competence of a layperson

— including both claimants and Board members — must be determined on a case-by-case basis. 

Jandreau, 492 F.3d at 1377. Simply put, any given medical issue is either simple enough to be

within the realm of common knowledge for lay claimants and adjudicators or complex enough to

require an expert opinion.

However, I would reiterate that even if a layperson is not competent to diagnose or determine

the cause of a particular condition, lay evidence is still competent to establish the occurrence of

observable events and medical symptoms. Davidson v. Shinseki, 581 F.3d 1313, 1316 (Fed. Cir.

2009). Accordingly, the Board should avoid overbroad statements about the competence of

laypersons and should carefully distinguish its treatment of lay testimony of symptoms and its

analysis of lay competence on issues of diagnosis or causation. Board decisions that make blanket

statements about lay competence while failing to acknowledge and discuss the competent lay

testimony of observable symptoms will face a rocky road on appeal.

More importantly, even if the Board acts properly in denying a claim, it must clearly

communicate the basis of the denial so that the claimant and future regional office adjudicators will

understand what types of evidence must be submitted in order to reopen the claim. See Kent

v. Nicholson, 20 Vet.App. 1, 9-11 (2006). Simply denying the claim with a terse sentence that the

lay evidence is not competent to establish the nature or origin of the claimant's disability will often

leave it unclear whether the Board is accepting the claimant's account of what happened in service

or what post service symptomatology was observed. In such cases, a remand will often serve to

illuminate the basis of the decision not only to inform the claimant and the Court, but to ensure that

13
a future attempt to reopen the claim can be properly adjudicated.

2. Credibility

Even where there are no competence issues, the value of medical evidence and opinions will

frequently turn on the credibility of lay testimony. A medical opinion based upon an incorrect

factual premise is of no probative value. See Reonal v. Brown, 5 Vet.App. 458, 461 (1993). Thus, 8

the Board, in its role as factfinder, "is obligated to, and fully justified in, determining whether lay

evidence is credible in and of itself." Buchanan v. Nicholson, 451 F.3d 1331, 1337 (Fed. Cir. 2006).

In determining whetherlay evidence is credible, the Board must frequently consider whether

there is corroborating evidence that supports the witness's account or suggests that the witness may

be untruthful or mistaken. In doing so, the Board must distinguish between two distinct situations. 

In some cases, there is a complete absence of any evidence to corroborate or contradict the

testimony, while in other cases there is evidence that is relevant either because it speaks directly to

the issue or allows a reasonable inference to be drawn by the Board as factfinder.

In general, the Board cannot determine that a veteran's lay evidence lacks credibility solely

because it is not corroborated by contemporaneous medical records. Buchanan, 451 F.3d at 1336. 

In cases involving disabilities related to combat, VA must presume lay evidence that describes the

in-service disease or injury is credible so long as it is "consistent with the circumstance, conditions,

or hardships of such service, notwithstanding the fact that there is no official record." 38 U.S.C.

§ 1154(b). This presumption is rebuttable only by clear and convincing evidence. Collette v. Brown,

82 F.3d 389, 393 (Fed. Cir. 1996). However, "the lack of contemporaneous medical records may

be a fact that the Board can consider and weigh against a veteran's lay evidence," when such

consideration is not prohibited by 38 U.S.C. § 1154(b). Buchanan, 451 F.3d at 1336.

I would note that an opinion based upon an incorrect factual premise is not the same as an 8

opinion based upon an incomplete factual premise. The Board may assign a lesser evidentiary value

to an opinion that is lacking in detail. Nieves-Rodriguez v. Peake, 22 Vet.App. 295, 302 (2008). 

However, the Board may not assume that additional information would necessarily change an

expert's opinion unless the issue falls within the competence of a layperson. Thus, an opinion that

lacks details may trigger the duty to assist by indicating that a condition may be related to service,

McLendon v. Nicholson, 20 Vet.App. 79, 83-84 (2006), and may lend some evidentiary support to

other opinions — favorable or unfavorable to the claim — that reach the same conclusion. NievesRodriguez, supra.

14
There is a wide variety of evidence that may corroborate or contradict a lay witness's

testimony, including prior consistent statements of the witness, prior inconsistent statements of the

witness, and current medical evidence, such as an x-ray showing the veteran has a healed fracture

in the allegedly injured area. Of course, this list is by no means exclusive. Cf. Stefl v. Nicholson,

21 Vet.App. 120, 124 (2007) (providing a nonexclusive list of factors a physician may discuss to

support an opinion).

One type of evidence that often causes confusion is contemporaneous SMRs that do not

record the alleged in-service disease or injury. As discussed above, in cases involving combat, VA

is prohibited from drawing an inference from silence in the SMRs. However, in cases where the

inference is not prohibited, the Board may use silence in the SMRs as contradictory evidence only

if the alleged injury, disease, or related symptoms would ordinarilyhave been recorded in the SMRs. 

See Buczynski v. Shinseki, 24 Vet.App. 221, 225-26 (2011) (noting that the Board could not rely on

silence in medical records to conclude that the appellant's injury was not "exceptionally repugnant"

because there was no medical reason for the examiner to address that subjective conclusion); FED.

R. EVID. 803(7) (the absence of an entry in a record may be evidence against the existence of a fact

if such a fact would ordinarily be recorded).

In order to rely on this inference, the Board must make two findings. First, the Board must

find that the SMRs appear to be complete, at least in relevant part. If the SMRs are not complete in

relevant part, then silence in the SMRs is merely the absence of evidence and not substantive

negative evidence. See McLendon, 20 Vet.App. at 85. If the SMRs are complete in relevant part,

then the Board must find that injury, disease, or related symptoms would ordinarily have been

recorded had they occurred. In making this determination, the Board may be required to consider

the limits of its own competence on medical issues. For example, the Board may reasonably

conclude that a compound fracture of a bone would have been observed and recorded, but would

require medical evidence to determine whether a particular type of cancer would have manifested

observable symptoms in service that likely would have been reported and recorded. Cf. Jandreau,

492 F.3d at 1377 n.4 (noting that a layperson is competent to identify a broken leg, but not a form

of cancer).

15
3. Application

In this case, the Board rejected the appellant's lay statements based both on competence and

credibility. The Board determined that the nature and origin of the appellant's knee injury were

medical issues beyond his competence. R. at 16. As to credibility, the Board stated:

Given that a right ACL tear is quite a significant injury, one would expect to see at

least some documentation of it in the [SMRs]. Also, one would expect that the

[appellant] would have mentioned this right knee injury on his report of medical

history at separation[,] but instead this document shows only that the [appellant]

reported two separate injuries to the left knee. In addition[,] the Board notes that

when the [appellant] initially filed his claim, he did not allege a right knee injury in

service. Instead he alleged only that he incurred a left knee injury and that his right

knee disability was secondary to that injury. The [appellant] then made similar

contentions in his Notice of Disagreement. For all of these reasons, the Board does

not find his more recent assertions of right knee injury in service credible.

R. at 15.

The flaw in the in Board's analysis is apparent. Although it concluded that the appellant was

not competent as a layperson to provide a medical opinion as to his ACL injury, the Board relied

upon its own lay opinion about the nature of the ACL injury to determine that it was a "significant

injury" that would have been documented in the SMRs. The Board cannot have it both ways. Either

this type of injury is relatively simple and within the common knowledge of a layperson or it is

complex enough that expert opinion or treatise evidence is required to understand its origins,

progression, and symptoms.

Based upon the development of the record so far, the ACL injury here appears to fall clearly

on the side of being medically complex. The record is devoid of any medical evidence establishing

the common symptomatology and usual treatment of an ACL injury. The record does contain a May

16, 1978, clinical record, which reported "effusion sighted r[ight] patella" and increased pain on

palpation and on leg lift of the medial and lateral meniscus regions and a limited range of motion. 

R. at 634. It also contains the appellant's testimony that he was seen at a clinic for a right knee injury

during service and was told that he had sustained only a sprain. R. at 58. It is not apparent whether

the clinical record can be evidence of an ACL injury in service or whethersuch an injurymight have

been misdiagnosed as a sprain. It is also not clear whetherthe appellant's symptoms in service would

have been of such severity that he would have likely reported them during his separation

16
examination, particularly if they had been inaccurately attributed to a sprain instead of a more severe

ACL injury. Therefore, I agree with the appellant's argument that the Board violated the Court's

holding in Colvin, supra, in finding that some documentation in his SMRs is expected as the Board

is not competent to make this determination based solely on its own medical beliefs. 

II. THE RELATIONSHIP BETWEEN THE BOARD AND VA MEDICAL EXPERTS

The second common issue that this case presents is the delicate balance between the Board's

primacy as a factfinder and its obligation to seek expert assistance in resolving complex medical

issues when appropriate.

In evaluating disability claims, the Board is obliged to reject insufficiently detailed medical

reports. 38 C.F.R. § 4.2 (2010) ("If a diagnosis is not supported by the findings on the examination

report or if the report does not contain sufficient detail, it is incumbent upon the rating board to

return the report as inadequate for evaluation purposes."). A medical opinion is adequate "where it

is based on consideration of the veteran's prior medical history and examinations and also describes

the disability, if any, in sufficient detail so that the Board's 'evaluation of the claimed disability will

be a fully informed one.'" Stefl, 21 Vet.App. at 123 (quoting Ardison v. Brown, 6 Vet.App. 405, 407

(1994)). It necessarily follows that the Board has an obligation to reject medical opinions that are

based upon an inaccurate factual premise. See Reonal, supra.

Although the basic requirement to obtain a detailed medical opinion based upon an accurate

factual premise is straightforward in principle, this case demonstrates the types of chicken-or-egg

problems that frequently arise in a system where adjudicators and experts do not converse directly. 

I agree with my colleagues that the request for a medical opinion in this case violated Austin. The

request in this case was unequivocal in stating that there was no right knee injury during service.

This statement makes the case at hand much like Austin, where VA made an explicit statement of

fact to an examiner that a reasonable physician would likely understand as a necessary premise of

the opinion being requested. As noted by the majority's opinion, the statement directly contradicted

the findings of the VA examiner in her initial December 2008 opinion and in the subsequent March

2009 opinion, the examiner found that the appellant's right knee injury was not related to service. 

R. at 49. In particular, her conclusion focused on whether the appellant's ACL injury was secondary

17
to his left knee condition and concluded that it was not related because it was a traumatic injury and

not an overuse injury. Id. The opinion does not address whether a traumatic injury to the right knee

occurred and the reader is left unsure whether the examiner revised her opinion based on additional

evidence she reviewed or because she felt bound by the Board's apparent finding against her earlier

conclusion. Therefore, regardless of the intent of the request, the Board's categorical statement must

be read as limiting the scope of the medical opinion, which had the result of violating Austin under

the facts of this case.

In this case, the opinion should have asked the physician whether there was any medical

reason to accept or reject the proposition that the appellant had a right knee ACL injury that could

have lead to his current condition. Cf. Daves v. Nicholson, 21 Vet.App. 46, 51-52 (2007) (where an

examinerstatesthat additional information mayhelp resolve a disputed medical issue, the Secretary's

duty to assist requires the Secretary to determine whether that information can be reasonably

obtained). The opinion could have specifically asked what types of symptoms would have been

caused by the type of ACL injury at issue and whether such an injury could have been mistaken for

a sprain or otherwise gone undiagnosed during service. Had it done so, perhaps this remand could

have been avoided.

Nonetheless, I think it is vital to stress that in many cases it is perfectly appropriate for a

request for a medical opinion to define the facts that a medical examiner must accept are true. 

Factfinding is a responsibility that is ultimately committed to the Board and not the VA medical

examiner. See Washington v. Nicholson, 19 Vet.App. 362, 367-68 (2005) (it is Board's duty to

determine probative weight of evidence). As mentioned earlier, where the duty to provide a medical

opinion applies, the Board must obtain an opinion that is based upon the factual predicate that it

finds to be true. In some cases, a medical opinion may help resolve certain kinds of disputed issues

of fact, such as whether a particular injury occurred in service or the precise nature of an intervening

injury after service. As a result, in many cases, it may make sense for the Board to make specific

findings before remanding a matter and require a medical opinion to accept those findings as true. 

In other cases, it is better for the Board to note that it needs to resolve a component factual question

and then to ask the physician to include in the report an opinion as to whether there is any medical

reason to accept or reject the veteran's testimony as to what occurred in the past. When the Board

18
seeks such an opinion, the examiner should explicitly address the issue, even if only to state that

there is no medical evidence that either supports or contradicts the lay testimony. Cf. Jones

v. Shinseki, 23 Vet.App. 382, 390-91 (2010) (concluding that a medical examiner may report that

an issue of medical causation cannot be resolved without resorting to speculation if that conclusion

is adequately explained).

Unfortunately, it is not always easy at the outset of a claim to identify all potential theories

of entitlement that have been raised or all the facts that must be determined to adequately resolve

each theory. Unlike a courtroom setting where a skilled advocate can respond to an expert's

testimony and methodically work through all the issues that arise, VA's system for obtaining expert

medical opinions through regional offices by written request means that developing evidence in a

complex case can be a piecemeal process. See Disabled Am. Veterans v. Sec'y of Veterans Affairs,

327 F.3d 1339, 1346-68 (Fed. Cir. 2003) (invalidating VA's proposal to allow the Board to develop

new evidence because it would violate claimant's right to one review on appeal). In many complex

cases, the understanding of both the medical expert and the Board will evolve through multiple

cycles of requests and opinions, which may or may not be accompanied by additional development

of other evidence. However, I would note that the number of iterations required to cover all the

issues can be substantially reduced if adjudicators are explicit as to whether any underlying facts are

in dispute at any given point and if medical experts are explicit in stating how and why they are

resolving any disputes as to the underlying facts. Although this may take extra effort initially, in the

long run it will reduce the burden of avoidable remands that VA too frequently inflicts upon itself

and provide faster, clearer decisions to claimants that have too often been waiting for many years for

resolution of their claims.
