PART VII — MOTIONS, BRIEFING, AMICI, AND ARGUMENT
Rule 67. Intervention, consolidation, severance, and related matters
Intervention
Intervention on appeal is exceptional. A motion must be filed within three days after the movant learns that its interest may be affected and must show:
a direct legal interest;
practical impairment without intervention;
inadequate representation by existing parties;
independent standing if required; and
no unfair disruption or expansion of the case.
An amicus brief is preferred when participation rather than party relief is sufficient.
Scope
An intervenor takes the case as it exists, may not enlarge jurisdiction or revive an expired claim, and must follow the schedule and limits assigned by the Court.
Consolidation
The Court may consolidate cases involving the same judgment, record, parties, or controlling question. Consolidation does not merge party identities, filing deadlines that already expired, judgments, or records unless the order expressly states.
Severance
The Court may sever a party, question, cross-appeal, or remedy to avoid delay, conflict, prejudice, or record confusion.
Alignment and divided briefing
The Court may realign parties for briefing or argument according to position on the judgment. It may set shared limits and require a coordinating attorney.
Related-case notice
A party must notify the Clerk within twenty-four hours after learning of a newly related proceeding, grant of review, settlement, or judgment.
