Rule 48 Contempt of court as penalty for willful noncompliance with these rules.

If you're an attorney, clerk, court reporter, or other court officer working on an appeal, you need to follow the appellate rules carefully. If you break an important rule on purpose, the appeals court can hold you in contempt of court.

This means the court won't just let a serious, willful violation slide. Before punishing anyone, though, the court has to give proper notice first. That means you'll be told about the problem and given a chance to respond before any contempt penalty is handed down.

This rule mainly targets willful violations, not honest mistakes. It's meant to hold people accountable for ignoring or disregarding rules that matter to how a case moves through the appeals process, rather than punishing small or accidental errors.
