TDIU: From Board Denial to Court Reversal

The two-step reality of a TDIU appeal: what the Board does with these issues, and — when veterans appeal a denial to the U.S. Court of Appeals for Veterans Claims — the arguments that get Board denials set aside.

What this is computed from: the 843 opinions and orders the U.S. Court of Appeals for Veterans Claims chose to publish (1996–2026), taken from the Court's own site and read by rule — the disposition from each decision's holding sentence, the reasoning type and conditions from the decision text, and every quoted passage verbatim from the cited decision with the veteran's name removed. No model summaries. Of 1,201 published documents, 83 petitions, 144 attorney-fee (EAJA) decisions, 48 procedural orders, 2 unreadable files, 8 documents without a docket number are excluded and 73 could not be classified, leaving 843. Published decisions are not all decisions: the Court decides roughly 8–9,000 appeals a year, most by unpublished single-judge decision or on the parties' joint motion; the official disposition counts below come from the Court's annual report, never from this sample. Selection effect: only Board decisions a veteran chose to appeal reach the Court, so no figure here describes all Board denials. Data build: 2026-10-07 (method v2, September 2026 — replaces an earlier build that used machine summaries of a mixed-court search corpus).

What the Court said the Board got wrong — verbatim

CAVC No. 20-5580 · 2022 · published opinion · reasoning: reasons or bases

“We hold that the Board failed to provide an adequate statement of its reasons or bases for its decision because it did not explain what it understood the phrase "near the perimeter[]" as used in the adopted M21-1 provision to mean.”

CAVC No. 17-0794 · 2018 · published order · reasoning: unclassified

“Second, the Board failed to apply to the appellant's case the statutes, regulations, and caselaw governing severance of service connection.”

CAVC No. 05-0355 · 2010 · published opinion · reasoning: tdiu

“Accordingly, the Board erred in not addressing TDIU and it must do so on remand.”

CAVC No. 05-3204 · 2008 · published opinion · reasoning: lay evidence

“Nonetheless, the Board failed to consider the lay evidence of record regarding the appellant's observable PTSD symptoms.”

Each passage is the Court's own sentence from the cited published decision, with the veteran's name removed; the reasoning label is a keyword tag for the decision as a whole.
