Adams v. Collins — obesity may be a disability for secondary service connection if it causes functional impairment

Court: CAVC   |   Year: 2025   |   Read Full Case Breakdown →

Key Takeaway
The Court held that obesity may be a disability for secondary service connection if it causes functional impairment of earning capacity, but it upheld the view that obesity is not a disease for direct service connection under section 1110. The Board’s denial was vacated because it failed to discuss favorable evidence of functional impairment.
Summary
The appellant sought service connection for obesity, including as secondary to service-connected PTSD. The Board denied the claim relying on VA General Counsel Precedent Opinion 1-2017 and on the view that obesity is not a disease or disability for VA compensation purposes. On appeal, the Court first held that it had jurisdiction to review whether obesity may be a disability for purposes of 38 U.S.C. § 1110, citing Larson v. McDonough and Saunders v. Wilkie. The Court concluded that the General Counsel’s blanket view that obesity is not a disability was not persuasive because Saunders defines disability as functional impairment of earning capacity, and nothing in Saunders supports excluding a condition merely because not every person with that condition is impaired. At the same time, the Court held that the General Counsel’s view that obesity is not a disease for purposes of direct service connection remained persuasive, so the Court did not disturb the Board’s direct-service-connection analysis. For secondary service connection, however, the Court held that the disease/injury requirement is not controlling in the same way and that the General Counsel’s regulation-based rationale was inconsistent with the governing statute and Spicer. The Court ultimately vacated and remanded the secondary-service-connection portion of the Board decision because the Board failed to discuss favorable evidence suggesting functional impairment, including a treatment record linking weakness and postural changes to obesity.

Aguilar v. Derwinski — A spouse must first prove claimant status before VA duty to assist or benefit-of-the-doubt applies

Court: CAVC   |   Year: 1991   |   Read Full Case Breakdown →

Key Takeaway
The Court affirmed denial of reopening because the appellant never established claimant status as the veteran’s legal spouse. Aguilar holds that proof of valid marital status is a threshold requirement; without it, VA has no duty to assist and no benefit-of-the-doubt analysis applies.
Summary
The appellant sought widow’s pension benefits as the surviving spouse of a Filipino veteran. The record reflected conflicting and ultimately unfavorable evidence regarding her alleged marriages, including statements that she had previously married another man and could not verify the claimed marriage to the veteran because civil records were destroyed. Although the Board had treated the matter as a reopening question, the Court affirmed on a different ground: the appellant had never established that she was a proper claimant because she failed to prove valid spousal status under the governing proof regulations.

The Court explained that, before VA’s duty to assist or the benefit-of-the-doubt rule can apply, a claimant must first submit the evidence required to establish threshold eligibility, including proof of marital status for a spouse seeking benefits. Without that proof, the person never attains claimant status under 38 U.S.C. § 5107(a). Judge Kramer concurred in the result but would have affirmed on a different basis, reasoning that the preponderance of the evidence was against the asserted marriage and that claimant status should be analyzed under the ordinary well-grounded-claim framework for material issues. The decision is important because it emphasizes that certain eligibility questions must be resolved before the merits of a benefits claim can be reached.

Alemany v. Brown — Board may not require claimants to prove service connection by a preponderance of the evidence; benefit-of-the-doubt applies when the record is in approximate balance

Court: CAVC   |   Year: 1996   |   Read Full Case Breakdown →

Key Takeaway
The Court held that VA improperly required the veteran to prove his claim by a preponderance of the evidence rather than applying the benefit-of-the-doubt standard under 38 U.S.C. § 5107(b). The Court also held that the Board impermissibly substituted its own medical judgment when it rejected a favorable medical opinion as “rank speculation” without independent medical evidence contradicting the opinion.
Summary
The veteran sought service connection for a seizure disorder, arguing that headaches and blackout symptoms documented during Vietnam service represented the onset of the later-diagnosed condition. A private physician testified that the veteran’s in-service symptoms could represent an “epileptic spark in the brain” and that wartime stress may have triggered the disorder.

VA examiners later stated that there was insufficient information to determine a “definite” or “obvious” etiology for the seizure disorder. The Board denied the claim, concluding that the evidence favoring the veteran did not outweigh the evidence against the claim and characterizing the favorable private opinion as “rank speculation.”

The Court vacated the Board decision. First, the Court held that the Board improperly substituted its own medical judgment by dismissing the favorable medical opinion without citing independent medical evidence refuting it. The VA opinions merely stated that the exact etiology was unclear; they did not exclude the possibility that the disorder began during service as the private physician suggested.

Second, the Court held that the Board applied the wrong evidentiary standard. The Board effectively required the veteran to prove that favorable evidence outweighed negative evidence, contrary to the benefit-of-the-doubt framework established in Gilbert v. Derwinski. The Court reiterated that a claim should be granted when the evidence is in approximate balance and that the veteran need not prove the claim by a preponderance of the evidence.

Alemany became an important case reinforcing the proper evidentiary burden in VA claims adjudication and limiting the Board’s ability to reject favorable medical opinions without competent contradictory evidence.

Allen v. Brown, 7 Vet. App. 439 (1995) — Secondary service connection includes aggravation by a service-connected disability

Court: CAVC   |   Year: 1995   |   Read Full Case Breakdown →

Key Takeaway
When a service-connected condition aggravates a non-service-connected condition, the veteran is entitled to compensation for the degree of additional disability resulting from the aggravation. A service-connected condition does not need to directly cause another disability for compensation to be awarded. If the service-connected condition aggravates or worsens another condition, the veteran may be compensated for the additional level of impairment resulting from that aggravation.
Summary
In Allen v. Brown, the Court fundamentally expanded the scope of secondary service connection in veterans law by holding that veterans may be compensated not only for disabilities directly caused by a service-connected condition, but also for any additional impairment resulting from aggravation of a non-service-connected condition by a service-connected disability.

The veteran was service connected for traumatic arthritis of the right knee and later developed arthritis in the left knee and both hips. Multiple medical opinions addressed whether the service-connected right knee condition altered the veteran’s gait and aggravated the non-service-connected joint conditions. One VA examiner specifically concluded that the left knee and hip conditions were “definitely aggravated” by the service-connected right knee arthritis.

Despite this evidence, the Board denied secondary service connection because it focused narrowly on whether the service-connected right knee condition directly caused the onset of the additional joint disabilities. The Court rejected that restrictive interpretation and held that VA compensation law focuses on impairment of earning capacity and functional disability, not merely the original medical cause of a disease process.

The Court determined that when a service-connected condition aggravates another condition, the veteran is entitled to compensation for the additional degree of disability resulting from that aggravation. The Court explained that compensation is warranted for the incremental increase in impairment caused by the service-connected condition, even if the underlying non-service-connected condition originated independently.

Allen became one of the foundational secondary service connection precedents in veterans law and remains central to aggravation analysis under 38 C.F.R. § 3.310.

Ascherl v. Brown — Duty to assist requires a thorough PTSD examination and development of relevant records

Court: CAVC   |   Year: 1993   |   Read Full Case Breakdown →

Key Takeaway
The Court vacated and remanded because the Board failed to satisfy its duty to assist on a PTSD claim, including by refusing a proper psychiatric examination and not adequately developing relevant records. It also stressed that PTSD is a distinct theory from schizophrenia and must be separately analyzed when reasonably raised.
Summary
The appellant served in Vietnam and had long-standing psychiatric diagnoses, including paranoid schizophrenia. After prior final denials of service connection for a nervous condition, he specifically sought service connection for PTSD and described in-service stressors and post-service symptoms. The Board reopened the claim based on new and material evidence, but then denied service connection and declined to order another psychiatric examination, reasoning that PTSD had never been diagnosed and schizophrenia had been consistently shown instead. The Court held that the Board had not adequately developed the PTSD theory and had failed to satisfy the statutory duty to assist under 38 U.S.C. § 5107(a).

The Court explained that once a veteran presents a well-grounded claim, VA must assist by developing the facts pertinent to the claim, including obtaining a thorough and contemporaneous examination that considers prior treatment records. Because the record was inadequate to determine whether the veteran had PTSD and, if so, whether it was related to service, remand was required. The Court also emphasized that PTSD is evaluated under different diagnostic criteria than schizophrenia and that reasonably raised issues must be addressed. On remand, the Board was instructed to seek relevant records, provide an adequate psychiatric examination, and address combat/stressor development as necessary, while also supplying adequate reasons or bases.

Ashley v. Brown — Board must provide adequate reasons or bases and may not rely on its own medical judgment in cause-of-death/PTSD analysis

Court: CAVC   |   Year: 1993   |   Read Full Case Breakdown →

Key Takeaway
The Court vacated and remanded because the Board failed to give adequate reasons or bases, did not properly address favorable lay and service evidence, and impermissibly relied on its own medical judgment in rejecting a PTSD-based cause-of-death theory.
Summary
The widow of a Vietnam veteran sought burial benefits and DIC, arguing that the veteran’s death from a gunshot wound was service connected because he suffered from PTSD and alcohol dependence related to his combat experiences. The record included service records suggesting stressful Vietnam experiences, lay statements describing behavioral change after service, and a private psychologist’s opinion linking the veteran’s symptoms and alcohol dependence to PTSD. The Board denied the claim, reasoning that the record did not clinically demonstrate PTSD and that the symptoms were consistent with alcohol dependence.

The Court vacated the Board decision and remanded. It held that the Board failed to provide adequate reasons or bases under 38 U.S.C. § 7104(d)(1) because it did not meaningfully address favorable stressor evidence, lay testimony, and supporting statements from family and friends. The Court also held that the Board erred by effectively making its own medical judgment about whether the veteran’s alcohol dependence could be related to PTSD, contrary to Colvin. In addition, the Court found the claimant had submitted competent evidence sufficient to make the claim plausible, and it emphasized the need to consider the benefit-of-the-doubt doctrine and, if necessary, seek an advisory medical opinion. The case matters because it reinforces that the Board must confront favorable evidence directly and cannot deny a medically complex theory without independent medical support.

AZ v. Shinseki — Absence of unreported sexual assault records is not pertinent evidence

Court: Federal Circuit   |   Year: 2013   |   Read Full Case Breakdown →

Key Takeaway
The Federal Circuit held that the absence of a service record documenting an unreported sexual assault is not pertinent evidence that the assault did not occur. The decision recognized the well-established reality that many victims of military sexual trauma (MST) do not officially report assaults during service.
Summary
The veteran sought service connection for PTSD based on military sexual trauma. VA denied the claim in part because service records did not document reports of the alleged assault.

The Federal Circuit rejected VA’s reliance on the absence of official reporting as negative evidence. The court explained that sexual assaults are frequently unreported and that silence in service records therefore lacks meaningful probative value regarding whether the assault actually occurred.

The court reviewed military and scientific studies documenting widespread underreporting of sexual assault and concluded that the Board errs when it treats the lack of official documentation as substantive evidence against the occurrence of MST.

AZ significantly strengthened evidentiary protections for MST claimants and reinforced the need for careful evaluation of lay evidence, behavioral changes, and alternative corroborating evidence in personal-assault PTSD claims.

Bankhead v. Shulkin — Suicidal ideation alone may support a 70% mental health rating

Court: CAVC   |   Year: 2017   |   Read Full Case Breakdown →

Key Takeaway
The Court held that the presence of suicidal ideation alone may support a 70% mental-health rating under 38 C.F.R. § 4.130 and that VA may not require evidence of suicidal intent, hospitalization, or active planning before recognizing suicidal ideation as occupational and social impairment contemplated by the rating criteria. The Court further held that the Board erred by improperly minimizing the severity of suicidal ideation and misapplying the mental-health rating framework.
Summary
Bankhead v. Shulkin is one of the most important modern mental-health rating cases interpreting VA’s General Rating Formula for Mental Disorders under 38 C.F.R. § 4.130.

The veteran sought a rating higher than 50% for service-connected PTSD. The record documented:

• chronic suicidal ideation,
• severe depression,
• anger,
• social isolation,
• impaired impulse control,
• occupational impairment,
• and serious interpersonal difficulties.

Despite repeated evidence of suicidal thoughts, the Board denied a 70% rating, reasoning that:

• the veteran had not been hospitalized,
• denied intent to act,
• maintained some social relationships,
• and generally remained oriented and functional.

The Court reversed the Board’s interpretation of the rating criteria.

The Court closely analyzed the structure of:

• the General Rating Formula for Mental Disorders,
• the symptom examples listed in § 4.130,
• and VA’s obligation to conduct a holistic analysis of occupational and social impairment.

The Court emphasized that:

• suicidal ideation appears only in the 70% rating criteria,
• and the regulation contains no requirement for:
• suicidal plan,
• hospitalization,
• preparatory behavior,
• active intent,
• or inpatient treatment.

The Court rejected the Board’s attempt to impose additional severity requirements not found in the regulation.

Importantly, the Court clarified that:

• both passive and active suicidal ideation are contemplated by the 70% criteria,
• and suicidal ideation alone may cause occupational and social impairment with deficiencies in most areas.

The Court also criticized the Board for:

• selectively focusing on evidence suggesting functioning,
• minimizing the significance of suicidal ideation,
• and improperly requiring symptom matching rather than evaluating overall impairment.

The Court reaffirmed that:

• mental-health ratings are not determined through mechanical checklist analysis,
• and the ultimate inquiry concerns the level of occupational and social impairment caused by symptoms.

The Court vacated and remanded because the Board failed to properly apply § 4.130 and failed to adequately explain why suicidal ideation did not support a higher rating.

Bankhead became one of the most heavily cited PTSD and mental-health rating cases in modern veterans law.

Banks v. Principi — Pain on motion required a 10% lumbosacral strain rating from the date of service connection; Board failed to address functional pain evidence

Court: CAVC   |   Year: 1992   |   Read Full Case Breakdown →

Key Takeaway
The Court held that the veteran was entitled to a 10% lumbosacral strain rating from the date of service connection because the record already showed characteristic pain on motion. It also vacated and remanded the higher-rating issue because the Board failed to adequately discuss the effect of extreme and consistent pain under §§ 4.40 and 4.45.
Summary
In this appeal from a Board of Veterans’ Appeals decision, the Court addressed two issues involving the veteran’s lumbosacral strain: whether a 10% rating should be effective from the date of service connection, and whether the veteran was entitled to more than a 20% rating. The Court concluded that the Board clearly erred in denying an earlier effective date for the 10% rating because the record already documented pain on motion at the time service connection began, satisfying Diagnostic Code 5295’s criteria for a compensable evaluation. The Court therefore ordered the Board to assign the 10% rating effective the date of service connection.

The Court also granted the Secretary’s request for a partial remand on the increased-rating issue because the Board had not adequately discussed the veteran’s allegations of extreme and consistent pain. Relying on 38 C.F.R. §§ 4.40 and 4.45, as well as Schafrath and Gilbert, the Court held that the Board’s reasons were insufficient for failing to address the functional impact of pain on the disability rating. The case is useful for practitioners seeking an earlier effective date for an initial musculoskeletal rating and for arguing that the Board must meaningfully analyze functional loss due to pain.

Barnes v. Derwinski — vacated and remanded for inadequate reasons or bases and rating analysis

Court: CAVC   |   Year: 1991   |   Read Full Case Breakdown →

Key Takeaway
The Court vacated and remanded the Board’s denial of an increased rating for anxiety disorder because the Board failed to provide adequate reasons or bases, did not discuss potentially relevant rating criteria, improperly relied on a nonexistent requirement of chronic worsening, and inadequately explained its benefit-of-the-doubt analysis.
Summary
Ronnie Lee Barnes sought an increased rating for his service-connected anxiety disorder, which was then rated 30 percent disabling. After a VA examination and an adverse regional office decision, the Board of Veterans’ Appeals affirmed the denial. On appeal, the Court granted the Secretary’s motion for remand and held that the Board’s decision contained multiple legal errors. The Court explained that the Board failed to provide adequate reasons or bases for its credibility and probative-value determinations regarding the hearing testimony and medical examinations, failed to discuss rating criteria potentially relevant to the headache component of the disability, and improperly relied in part on a requirement that the increase be “chronic,” which the Secretary conceded was not legally required. The Court also found the Board’s explanation of why the benefit-of-the-doubt doctrine did not apply to be inadequate. The decision was vacated and remanded for reconsideration and any further examination deemed warranted because of the passage of time.

Barr v. Nicholson — Lay testimony may establish observable varicose veins and continuity of symptomatology

Court: CAVC   |   Year: 2007   |   Read Full Case Breakdown →

Key Takeaway
The Court held that once VA undertakes to provide a medical examination or opinion, it must ensure that the examination is adequate. The Court also held that lay testimony may be competent to establish the presence of observable symptomatology, including continuity of symptoms for conditions capable of lay observation such as varicose veins.
Summary
The veteran sought service connection for varicose veins, asserting that the condition began during service and had continued since that time. The Board denied the claim after relying on a VA medical examination that concluded the disability was unrelated to service.

The Court found the VA examination inadequate because the examiner failed to meaningfully address whether the veteran’s current varicose veins were related to the observable symptoms described during and after service. The Court emphasized that once VA elects to provide a medical examination, the duty to assist requires that the examination be adequate for adjudication purposes.

The Court also discussed the competency of lay evidence. It explained that varicose veins are a condition capable of lay observation because they are visually observable and identifiable without specialized medical training. Therefore, the veteran’s testimony concerning continuity of symptoms was competent evidence that required proper consideration.

Barr became one of the foundational veterans-law cases governing adequacy of VA examinations and the competency of lay evidence concerning observable conditions.

Bastien v. Shinseki — Federal Circuit lacks jurisdiction to reweigh factual evidence; Rizzo controls VA expert competency challenge

Court: Federal Circuit   |   Year: 2010   |   Read Full Case Breakdown →

Key Takeaway
The Federal Circuit affirmed because most of the claimant’s arguments attacked factual weighing beyond its jurisdiction, and under Rizzo VA was not required to affirmatively prove expert qualifications absent a specific competence challenge. The decision also upheld the Veterans Court’s enforcement of its rule against citing nonprecedential opinions.
Summary
Mr. Bastien served from 1972 to 1976 and worked in a radiation facility where he handled monkeys used in radiation experiments. After his death from pneumonia resulting from Waldenström’s macroglobulinemia, his widow sought DIC and related benefits based on alleged in-service ionizing radiation exposure. The Board found the evidence conflicted on both radiation dose and medical nexus, and it assigned greater probative value to VA physicians’ opinions concluding that the cancer was unlikely to be caused by service radiation exposure. The Veterans Court affirmed, and the Federal Circuit in turn held that most of the widow’s arguments merely disputed factual findings and the Board’s weighing of evidence, which the court lacked jurisdiction to review under 38 U.S.C. § 7292(d)(2). The court further held that Rizzo controlled the expert-qualification issue: unless the claimant specifically challenges a VA expert’s competence or qualifications, VA is not required to present affirmative proof of the physician’s expertise before the Board may rely on the opinion. Finally, the court upheld the Veterans Court’s decision to strike an opening brief that cited nonprecedential opinions in violation of its rules. The case matters primarily for jurisdiction and evidentiary strategy in Federal Circuit appeals, and for preserving a concrete, specific challenge if a claimant intends to contest a VA medical expert’s competency.

Begin v. Derwinski — Remand required where psychiatric impairment was not clearly separated from nonservice-connected factors

Court: CAVC   |   Year: 1992   |   Read Full Case Breakdown →

Key Takeaway
The Court remanded a PTSD rating and TDIU appeal because the medical evidence did not clearly separate the effects of PTSD from nonservice-connected problems such as depression, self-worth issues, and alcohol abuse. The decision underscores that disability ratings must be based only on impairment from the service-connected condition and that inadequate development requires remand.
Summary
The appellant, a Vietnam-era Army veteran, sought a higher PTSD rating and a total disability rating based on individual unemployability. The Board had assigned a 50 percent PTSD rating and denied TDIU. On review, the Court noted that the record contained evidence supporting both considerable and severe psychiatric impairment, but the critical problem was that the medical evidence did not clearly distinguish the effects of PTSD from other possible nonservice-connected causes, including depression, self-esteem problems, and alcohol abuse. Because 38 C.F.R. § 4.1 requires accurate and fully descriptive medical examinations focused on the limitation imposed by the disabling condition, the Court held the record was inadequately developed. The Court reversed and remanded for further development, and held that the TDIU claim was inextricably intertwined with the rating issue and had to be addressed on readjudication.

Bernard v. Brown— Board must avoid prejudicing the claimant when deciding issues not addressed by the RO

Court: CAVC   |   Year: 1993   |   Read Full Case Breakdown →

Key Takeaway
The Court held that the Board may decide the merits of a reopened claim even if the RO only addressed new and material evidence, but it must first consider whether the claimant was prejudiced by the Board’s deciding a question not addressed below. The Court also held that the Board may not make unsupported medical conclusions and must rely on independent medical evidence.
Summary
The appellant, a Vietnam veteran, sought service connection for multiple sclerosis after prior final denials. The Board determined that new and material evidence had been submitted and proceeded to adjudicate the merits of the service-connection claim rather than remanding to the RO. The Court held that the Board had jurisdiction to decide the merits because the reopening question and the underlying entitlement question were part of the same “matter” under 38 U.S.C. §§ 7104(a) and 511(a). However, the Court vacated and remanded because the Board failed to consider whether the veteran was prejudiced by the Board’s addressing the merits in the first instance, given that the RO and statement of the case had only addressed reopening. The Court also held that the Board improperly made a medical conclusion—attributing urinary symptoms to other disorders—without supporting medical evidence, contrary to Colvin. On remand, the Board was required to apply the VA General Counsel’s prejudice analysis and provide adequate reasons or bases supported by medical evidence.

Bilharz v. Collins — Due process does not categorically require the same Board member to hear and decide an AMA appeal

Court: CAVC   |   Year: 2025   |   Read Full Case Breakdown →

Key Takeaway
The Court held that the AMA does not categorically violate due process when one Board member conducts a hearing and another decides the appeal, but it also held that Bryant hearing duties still apply in AMA hearings. The Court remanded Pinto for a Bryant violation and Bilharz for inadequate reasons or bases.
Summary
In these consolidated appeals, the Court addressed two recurring AMA issues and set aside both Board decisions. First, the appellants argued that fair process and due process categorically require the same Board member who conducts a hearing to also decide the appeal. The Court rejected that categorical argument, holding that neither the Due Process Clause nor fair process requires the same Board member in every case. The Court reasoned that due process is flexible, that Board decisions are made on de novo review of the record, and that the administrative burden of a same-member rule would be substantial. The Court left open only the possibility of an as-applied due process violation on a case-specific record, but found none here.

Second, the Court held that the hearing duties recognized in Bryant continue to apply in AMA Board hearings, even though the regulatory anchor changed from 38 C.F.R. § 3.103(c)(2) to § 20.705. The Court relied on the nonexclusive language of § 20.705 and VA’s rulemaking commentary stating that the AMA amendments were not intended to limit Bryant. Applying that rule, the Court found that the Board member who conducted Mr. Pinto’s hearing did not fulfill the duty to explain the issues or suggest the submission of potentially advantageous evidence, so Pinto’s PTSD and TDIU appeal was remanded.

Finally, the Court agreed with Mr. Bilharz that the Board’s reasons or bases were inadequate because it dismissed his lay testimony with conclusory statements about competency without clearly addressing credibility or explaining the treatment of favorable evidence. The Court therefore remanded Bilharz’s service-connection claims as well.

Black v. Brown — Board may not substitute unsupported medical judgment; further medical development required

Court: CAVC   |   Year: 1993   |   Read Full Case Breakdown →

Key Takeaway
The Court vacated and remanded because the Board relied on unsupported medical speculation about the cause of the veteran’s low back disorder. The Court held that additional medical development was needed where both in-service and post-service trauma were present and the existing opinions were conclusory.
Summary
The veteran sought service connection for a low back disorder after an in-service 1963 back injury and later post-service trauma. The claim had been repeatedly denied, reopened, and reconsidered over many years, with various private physicians and lay witnesses offering opinions that attempted to link the current disability to service. The Board ultimately denied the claim, characterizing favorable medical opinions as speculative and concluding that the more likely cause was a post-service injury.

The Court held that the Board’s own causation conclusion was equally speculative because it lacked objective medical support. Although the Court agreed that some of the favorable private opinions were conclusory and history-based, it emphasized that the Board could not substitute its own ungrounded medical judgment for competent medical evidence. Because the record reflected both in-service and post-service back trauma, but no adequate medical opinion explained the relative contribution of each, the Court vacated the decision and remanded for additional medical development, including examination or independent medical opinion if needed.

Practically, the decision stands for the proposition that when medical causation remains unresolved, VA must develop the record rather than resolve it through Board speculation. It is especially useful in service-connection cases involving competing traumatic events and thin medical rationale.

Black v. Brown — Competent medical nexus evidence is required to well ground a secondary service-connection claim

Court: CAVC   |   Year: 1997   |   Read Full Case Breakdown →

Key Takeaway
The Court held that a nurse’s medical opinion was not sufficiently probative to well ground the claim where the record did not demonstrate specialized cardiology expertise, treatment involvement, or supporting medical evidence linking the veteran’s service-connected disabilities to heart disease. The Court distinguished more probative nursing opinions involving direct treatment participation and relevant medical expertise.
Summary
The veteran sought service connection for heart disease secondary to multiple service-connected combat injuries, including retained shell fragments, trench foot, and median nerve impairment. He argued that poor circulation, chronic pain, and anxiety resulting from his service-connected disabilities contributed to his heart attack and coronary disease.

At a hearing, the veteran’s wife, a registered nurse, testified that she believed the retained shrapnel and circulation problems contributed to the veteran’s heart condition. She also stated that physicians had informally suggested a possible relationship between retained foreign bodies and the veteran’s cardiovascular problems.

The Court affirmed the Board’s determination that the claim was not well grounded. The Court acknowledged that the veteran’s wife possessed medical training, but concluded that the record did not establish specialized expertise in cardiology, participation in the veteran’s treatment, or sufficient evidentiary support linking the service-connected conditions to the heart disease.

The majority distinguished prior cases such as Goss v. Brown, where nursing testimony had been accepted as sufficient medical evidence because the nurse directly participated in treatment relevant to the claimed condition. The Court therefore concluded that the nurse’s testimony in this case lacked sufficient probative value to satisfy the nexus requirement.

The dissent strongly criticized the majority’s reasoning, arguing that the Court improperly imposed specialization and treatment-participation requirements inconsistent with prior precedent governing medical competency and well-grounded claims.

Boeck v. Brown — Board may not supply its own medical judgment; § 1151 claim must be well grounded

Court: CAVC   |   Year: 1993   |   Read Full Case Breakdown →

Key Takeaway
The Court vacated the Board’s denial of service connection for ulcerative colitis because the Board impermissibly supplied its own medical conclusion without supporting medical evidence, but affirmed the denials of service connection for a prostate disorder, PTSD, and § 1151 benefits because those claims lacked a plausible evidentiary basis.
Summary
The veteran sought service connection for ulcerative colitis, a prostate disorder, and PTSD, and also sought § 1151 benefits for prostate cancer allegedly caused by VA treatment. The Board denied all claims. On appeal, the Court vacated and remanded only the ulcerative colitis issue. It held that the Board could not deny the claim based on its own medical conclusion that there was no etiological relationship between ulcerative colitis and service-connected gastrointestinal disabilities when the Board cited no medical evidence or treatise support and effectively substituted its own medical judgment. The Court affirmed the remaining issues. For the prostate disorder and PTSD claims, it found a plausible evidentiary basis for the Board’s factual findings, including the absence of in-service prostate pathology and the lack of PTSD symptoms on examination. For the § 1151 claim, the Court held the claim was not well grounded because there was no competent medical evidence that the veteran had prostate cancer at the time of VA treatment or that VA failed to diagnose an existing condition; the veteran’s lay assertions and a vague physician statement were insufficient.

Bowling v. McDonough, 38 C.F.R. § 3.354(a) is not facially vague, and extra-record evidence was properly excluded

Court: Federal Circuit   |   Year: 2022   |   Read Full Case Breakdown →

Key Takeaway
The Federal Circuit affirmed rejection of a facial vagueness challenge to VA’s insanity regulation and held that it was not futile to present supporting evidence to the Board even though the Board could not declare the regulation unconstitutional.
Summary
Charlotte Bowling and Kevin Appling challenged the constitutionality of 38 C.F.R. § 3.354(a), the VA regulation defining insanity for purposes of the statutory bar to benefits attached to certain other-than-honorable discharges. The Board had found that neither claimant met the regulation, and the Veterans Court declined to consider extra-record evidence the claimants offered to support a facial vagueness challenge. The Veterans Court also rejected the vagueness claim on the merits. On appeal, the Federal Circuit held that the Veterans Court properly confined review to the Board record and correctly refused to excuse the claimants’ failure to develop the factual basis for their constitutional challenge before the Board. The court relied on prior Federal Circuit precedent holding that the Board’s inability to invalidate a measure on constitutional grounds does not necessarily make record development futile. The court further held that the regulation was not shown to be facially vague, emphasizing that the regulation and binding interpretive authorities provide sufficiently objective standards and that the claimants had not shown vagueness as applied to them. The court affirmed without reaching class certification.

Bradley v. Peake — TDIU based on a single disability can satisfy 38 U.S.C. § 1114(s)

Court: CAVC   |   Year: 2008   |   Read Full Case Breakdown →

Key Takeaway
A TDIU award based on a single service-connected disability may satisfy the “rated as total” requirement under 38 U.S.C. § 1114(s), potentially establishing entitlement to SMC when separate disabilities independently combine to 60 percent or more. VA cannot deny SMC simply because the veteran lacks a schedular 100% rating if TDIU is based on a single disability.
Summary
In Bradley v. Peake, the Court held that a TDIU award based on a single disability can satisfy the “service-connected disability rated as total” requirement for Special Monthly Compensation (SMC) under 38 U.S.C. § 1114(s).

The case involved a combat veteran with numerous shell fragment wound injuries, PTSD, multiple muscle group injuries, scars, and a longstanding TDIU award. VA later replaced his TDIU with a 100% combined schedular rating after additional disabilities were rated.

VA denied SMC because the veteran did not have a single schedular 100% disability rating. The Court rejected that interpretation. It held that neither 38 U.S.C. § 1114(s) nor 38 C.F.R. § 3.350(i) limited “a service-connected disability rated as total” to only schedular 100% ratings.

The Court further held that VA must determine whether TDIU was based on a single disability because, if so, the veteran could qualify for SMC when additional disabilities independently combined to at least 60 percent.

Importantly, the Court emphasized VA’s obligation to maximize benefits and held that VA improperly substituted a 100% combined rating for TDIU without considering whether preserving TDIU based on a single disability would create entitlement to additional SMC compensation.

Bradley became one of the foundational modern cases governing VA’s duty to maximize benefits and the relationship between TDIU and SMC.
