PART VII — MOTIONS, BRIEFING, AMICI, AND ARGUMENT
Rule 66. Amicus curiae briefs
Purpose
An amicus brief should bring relevant law, institutional perspective, technical context, or record-neutral information not adequately presented by the parties. A repetitive brief burdens the Court and may be rejected.
Eligibility and signature
An amicus brief must be signed by a Ridgeway attorney authorized to appear, except that the Court may invite a government body, court, or technical expert to file through an authorized representative.
Notice
The amicus must notify all parties of the intended filing and position at least twenty-four hours before filing, unless the Court shortens the period. Consent is not required.
Petition stage
At the petition stage, an amicus brief is due no later than the opposition deadline. If no opposition is filed or requested, it is due within seven days after service of the petition. The amicus may not delay distribution.
Merits stage
A merits amicus supporting a party is due within two days after service of that party’s principal brief. An amicus supporting neither party is due within two days after service of the opening brief. No amicus reply is permitted.
Contents and disclosures
The brief must state:
the amicus’s identity, interest, and relevant expertise;
the party or result supported;
why the filing will assist;
whether a party, counsel, government office, Roblox group, campaign, law firm, or other person authored any part;
every person or entity providing money, staff, research, or coordinated drafting;
any relationship, alternate account, common control, or organizational affiliation with a party; and
a concise summary, argument, and conclusion.
Limits
An amicus may not introduce case-specific evidence, expand jurisdiction, control the litigation, or repeat a party’s brief under another name.
Government filing
The Attorney General or Solicitor General may file on behalf of the State, county, municipality, or agency without a motion for leave, subject to timing and disclosure of the governmental interest.
Rehearing and emergency
An amicus filing on rehearing or emergency relief requires leave or Court invitation.
