Filing deadline — often 7 days after supported party's principal brief [VERIFY] |

Word/page limits for amicus briefs [VERIFY] |

Pitfalls
- Duplicating party briefs — add distinct law, data, or consequences only
- Introducing new issues — frame extra-record materials as legislative facts or policy context
- Citation errors — use Bluebook format; verify every authority
- Advocacy excess — keep tone neutral, precise, judicially useful
- Ignoring local rules — jurisdictional rules override FRAP/SCOTUS defaults
- Confidential information — redact or omit anything not in the public record
