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

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.

The Board may not base medical causation findings on its own unsubstantiated medical opinion, and a § 1151 claimant must present competent medical evidence sufficient to make the claim well grounded.

When the Board denies a claim on medical causation grounds, advocates should check whether the Board cited actual medical evidence rather than its own inference. For § 1151 claims, the record must include competent medical support showing both the underlying condition and a plausible causal link to VA treatment.

Boeck is an early but important case on two recurring appellate problems: Board medical overreach and the threshold evidentiary showing for § 1151 benefits. It is especially useful for challenging decisions where the Board states a medical conclusion without medical support, or where a claimant’s proof depends on speculation rather than competent medical evidence.

Improper Medical Inference [Evidentiary Errors]

A veteran seeks secondary service connection for a bowel condition, but the Board denies the claim by stating—without citing any medical opinion—that no medical principles support a relationship. Boeck can be used to argue that the Board cannot supply that medical conclusion on its own.

Use this case to challenge Board denials that rest on unsupported medical reasoning and to attack § 1151 theories lacking competent medical evidence of an existing condition and causal linkage. It also supports remand where the Board should have obtained medical evidence instead of substituting its own judgment.
