Amicus Curiae Brief
Produces a procedurally compliant, substantively additive amicus brief. The amicus must deliver a perspective the parties cannot — restating party arguments risks striking, sanctions, or credibility loss.
Quick Start
- Gather intake (forum, stage, party briefs, amicus profile, disclosure facts)
- Build compliance map from governing rules
- Select an additive thesis that fills a gap in party arguments
- Draft brief with record-safe fact handling
- Verify all authorities and run quality audit
Intake (Mandatory)
Collect before drafting (skip only if user says "use defaults"):
- Forum/stage — court, caption, docket number, cert vs. merits, panel or en banc
- Deadlines — docket schedule, amicus-specific orders
- Party briefs — at minimum the supported party's principal brief
- Record anchors — record cites used by parties for adjudicative facts
- Amicus profile — entity, mission, expertise, relationship to parties
- Position — supports petitioner/respondent/neither; requested disposition
- Consent/leave — consent status, whether motion for leave is needed
- Disclosure facts — authorship and funding (Rule 29(a)(4)(E) / Rule 37.6)
- Formatting — word/page limits, font, cover color, copy counts
- Sources — primary sources for legislative facts or empirical claims
Defaults if unspecified: federal circuit FRAP 29; standard amicus word limits; hybrid expertise/systemic-consequences thesis.

| Rule Set |
FRAP 29/32, Supreme Court Rule 37, or state rule |

Step 2: Select Additive Thesis
Extract party argument chain; identify the gap. Choose one primary thesis:

- Systemic consequences — how ruling affects non-parties and broader systems
- Doctrinal harmonization — fit with related precedent or statutory schemes
- Historical/structural framing — legislative history, original understanding, institutional design
State thesis in one sentence for the Summary of Argument.

Use bracketed placeholders ([VERIFY], [X words], [date]) for any unconfirmed detail.
Disclosure and Certificates (Verbatim Required)
- Disclosure statement (FRAP 29(a)(4)(E), Supreme Court Rule 37.6, or forum equivalent): copy current rule language verbatim after verification; do not paraphrase required rule text.

Step 4: Deliverables
Prefix every output with:
- Assumptions — forum, posture, consent status, thesis, governing rules
- Open Items — missing briefs, unconfirmed rules, outstanding disclosure facts
Post-Draft Check (Mandatory)
Ask after delivering initial draft:
- Does the thesis add a perspective the party briefs do not?
- Are disclosure facts (authorship, funding) confirmed?
- Should additional authorities or empirical sources be added?
- Is the tone correct for this court and amicus role?
Quality Audit
Verify before finalizing:
Critical Rules
- Never restate party arguments — thesis must be additive
- Never introduce adjudicative facts outside the record
- Never fabricate citations, rule text, or empirical data — flag
[VERIFY] if unconfirmed
- Do not assume FRAP applies — confirm state appellate rules when applicable
- Supreme Court briefs: Rule 37.6 disclosures + Supreme Court Bar signature
[VERIFY]
- State rules (CA 8.200(c), NY 500.23) must be independently confirmed
[VERIFY]
- All output requires attorney review before filing
