A Court of Appeals for Veterans Claims case often looks like it begins with one document: the Notice of Appeal. In practice, many of the biggest problems start earlier.
That is one reason CAVC cases can feel unusually frustrating. By the time a veteran or surviving family member starts thinking about court, the Board of Veterans’ Appeals has already issued a final decision, the clock is already running, and small misunderstandings can shape the entire appeal. The CAVC is not another round of claim development inside VA. It is a federal court reviewing whether the Board made legal error, and that change in posture affects everything from deadlines to strategy. The Court’s official guidance explains that a Notice of Appeal generally has to be received within 120 days of the Board’s mailing of the decision, and the date stamped on the front of the Board decision is treated as the mailing date (USCAVC appeal instructions; 38 U.S.C. § 7266).
If you are still getting oriented, it may help to start with a broader overview of how a Board decision gets reviewed by the veterans court. In this post, you’ll learn about six CAVC appeal mistakes that often begin before the Notice of Appeal is filed, why they matter, and what veterans and families may want to watch for when speaking with counsel.

At the Board, the focus often includes evidence, medical opinions, credibility findings, and whether VA satisfied duties tied to the benefits system. At the CAVC, the focus shifts toward the Board decision itself: whether the Board applied the law correctly, gave adequate reasons or bases, followed required procedure, and addressed the right issues. The Court’s process includes briefing, possible Rule 33 staff conference procedures, and review based on the agency record rather than fresh evidence gathering (USCAVC court process; USCAVC Rule 33).
That is why early decisions matter. A missed issue, a misunderstood deadline, or a poorly framed theory can follow the case all the way into briefing.
One of the most common mistakes is conceptual: assuming the CAVC is simply the next VA step.
It is not. The CAVC is a federal court with its own rules, filing requirements, and scope of review. The Court reviews final Board decisions. It does not function like a regional office, a Higher-Level Review lane, or a supplemental claim lane. The Court’s own materials emphasize that the appeal starts only after a final Board decision and that the Court can dismiss a case if it lacks jurisdiction or if the rules are not followed (USCAVC appeal instructions; USCAVC court process).
This misunderstanding creates several downstream problems:
Here’s what this often means in practical terms: the question is frequently less “Was the veteran disabled?” and more “Did the Board analyze the evidence and law correctly when it answered that question?” Veterans who want a fuller explanation of that change in posture may also find it helpful to read about what shifts once a veterans benefits case leaves VA and enters court review.
An attorney with documented CAVC experience may help identify whether the appeal is really about inadequate reasons and bases, a duty-to-assist issue preserved for court review, an incorrect legal standard, jurisdiction, effective date analysis, or a missed theory of entitlement.
This is the mistake people hear about most, but it often begins earlier than they think.
Under 38 U.S.C. § 7266, a person adversely affected by a final Board decision generally has 120 days to file a Notice of Appeal with the Court. The CAVC’s filing instructions say the Notice of Appeal has to be received by the Court no later than 120 days after the Board mailed notice of the decision, and the date stamped on the front of the Board decision is treated as the mailing date (USCAVC appeal instructions; USCAVC Rule 4).
