Workflow

Overview

CaseMark's Amicus Brief skill automates the drafting and analysis of friend-of-the-court briefs for U.S. appellate courts. It produces fully structured, rule-compliant briefs with Bluebook-ready citations while ensuring the amicus adds a genuinely unique perspective that doesn't duplicate party arguments.

Drafting an effective amicus curiae brief requires navigating complex procedural rules, developing a perspective that genuinely adds value beyond the parties' arguments, and ensuring meticulous Bluebook citation formatting—all under tight filing deadlines. The manual process of compliance checking, authority mapping, and section structuring can consume days of attorney time.

CaseMark's AI analyzes the case materials and party briefs to identify the amicus's unique contribution, then generates a fully structured brief with proper citations, required disclosures, and rule-specific formatting. The result is a filing-ready amicus brief that meets every procedural requirement while articulating a compelling, non-duplicative perspective.

Questions

Which courts and rule sets does this tool support?

CaseMark supports federal appellate courts under FRAP 29, the U.S. Supreme Court under Rule 37, and state appellate courts with equivalent amicus rules. The AI adapts formatting and section requirements to match your specific jurisdiction.

How does the AI ensure the brief adds a unique perspective?

CaseMark analyzes the parties' existing briefs and arguments to identify gaps, then develops the amicus's distinct contribution—whether empirical evidence, industry expertise, or policy implications—so the brief never duplicates what the parties have already argued.

Are the citations formatted in proper Bluebook style?

Yes. CaseMark generates all citations in Bluebook format, including the Table of Authorities. The AI cross-references cited authorities against your source materials to ensure accuracy and proper citation form.

Can I use this to review an existing amicus brief instead of drafting one?

Absolutely. CaseMark offers an Analysis mode that provides a structured critique of any existing amicus brief, including a compliance table checking rule adherence, argument strength, citation accuracy, and formatting requirements.

Does the tool handle consent and motion-for-leave requirements?

Yes. CaseMark checks whether consent of the parties has been obtained and, if not, can draft the accompanying motion for leave to file the amicus brief in accordance with the applicable court rules.

What word and page limits does the AI enforce?

CaseMark automatically applies the word or page limits specified by the applicable rule set—whether FRAP 29's limits, Supreme Court Rule 37's limits, or local court rules you specify—and flags any overages before you finalize the brief.
