Amicus Brief

Draft or evaluate U.S. appellate amicus briefs that add a distinct, rule-compliant perspective.

Prerequisites

Gather before starting:

1. Case posture, issues presented, and parties' arguments or briefs
2. Amicus identity, constituency, and concrete stake in outcome
3. Applicable rules (FRAP 29, state equivalent, or SCOTUS Rule 37) and local formatting requirements
4. Consent status or plan for motion for leave; filing deadline
5. Legal authorities and any empirical or policy materials to cite

Quick Start

Select mode:

Mode	Trigger	Output
Drafting	Creating a new brief	Full brief with all required sections
Analysis	Reviewing an existing brief	Structured critique with compliance table

Drafting Workflow

- [ ] Confirm jurisdiction and rule set (federal, state, SCOTUS)
- [ ] Verify consent or prepare motion for leave
- [ ] Identify unique contribution — do not duplicate party arguments
- [ ] Build authority map: controlling precedent, persuasive precedent, statutes, secondary sources
- [ ] Integrate expertise or policy evidence with clear sourcing
- [ ] Draft sections in required order; verify word/page limits
- [ ] Add disclosure statements, certificates, and signatures
- [ ] Run compliance pass: Bluebook, formatting, service, ECF rules

Required Sections (adapt to court rules)

• Table of Contents
• Table of Authorities
• Statement of Interest
• Summary of Argument
• Argument (headed sections)

Analysis Workflow

- [ ] Flag new issues not raised by parties
- [ ] Check rule compliance and formatting
- [ ] Summarize core arguments and policy impacts

Rule Compliance Checks

Verify for the specific court:

Requirement	Confirm
Consent or leave	Parties' consent filed or motion for leave prepared
Timing	Filing deadline — often 7 days after supported party's principal brief [VERIFY]
Length	Word/page limits for amicus briefs [VERIFY]
Disclosure	Authorship and funding (FRAP 29(a)(4)(E); SCOTUS Rule 37.6)
Corporate disclosure	Entity disclosure if required (FRAP 26.1 or local equivalent)
Service	Proper service on all parties with proof
Format	Font, spacing, margins, cover color, ECF requirements

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
