# 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) - Conclusion - Certificates and disclosures ### Argument Structure | Section | Purpose | |---|---| | Interest | Establish legitimacy and why amicus perspective matters | | Summary | One page max — unique thesis and outcome requested | | Argument | 2–4 points, each tied to controlling law and practical impact | | Conclusion | Clear request for disposition or rule adoption | ### Template ```text [Cover / Caption] TABLE OF CONTENTS TABLE OF AUTHORITIES STATEMENT OF INTEREST [Amicus constituency, expertise, direct stake.] CONSENT / LEAVE STATUS [Consent or motion for leave.] SUMMARY OF ARGUMENT [Thesis and outcome sought.] ARGUMENT I. [Legal principle + unique perspective] II. [Policy/technical evidence tied to law] III. [Practical consequences or administrability] CONCLUSION [Requested disposition.] DISCLOSURE OF AUTHORSHIP AND FUNDING [FRAP 29(a)(4)(E) / SCOTUS Rule 37.6.] CORPORATE DISCLOSURE STATEMENT [If required.] CERTIFICATE OF COMPLIANCE [Word count method and total.] CERTIFICATE OF SERVICE [Method, date, recipients.] ``` ## Analysis Workflow ``` - [ ] Identify distinct contribution; check for duplication of party arguments - [ ] Assess credibility and fit of amicus interest - [ ] Evaluate authority strength and citation accuracy - [ ] 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
