Background

Israel Cantu, a veteran, appealed a Veterans Court order that dismissed his petition for a writ of mandamus. Cantu had sought to compel the Board of Veterans’ Appeals to adjudicate claims for an effective date before November twenty-first, two thousand and fifteen. While his petition was pending, the Board issued a decision in July of two thousand and twenty-five, resolving the claims. The Veterans Court dismissed the petition as moot because the relief sought was no longer available.

The court’s reasoning

The court explained that its jurisdiction over Veterans Court decisions is limited by statute. It can only review challenges to the validity or interpretation of a statute or regulation, or constitutional issues. It cannot review factual determinations or the application of law to specific facts. The court found the petition moot because the Board had issued the decision Cantu sought. Furthermore, the Veterans Court did not interpret or rely on any statutes or regulations in its dismissal, so no non-frivolous legal question existed for the Federal Circuit to review. The court also noted that a writ of mandamus cannot substitute for the ordinary appeal process.

What it means going forward

Veterans seeking mandamus relief must ensure their claims remain live and that the lower court addresses a specific legal question regarding statute or regulation interpretation to preserve appellate jurisdiction.
