Rule 23(f) permits a petition to the court of appeals within 14 days of a certification order. Review is discretionary, and the appellate court considers whether the ruling is questionable and whether it effectively ends the litigation.
The deadline is jurisdictional and not extendable.
Alternative Names:
23(f) Petition, Class Certification Appeal
Why it Matters?
The fourteen-day window is the trap, since it runs from entry and cannot be extended, which leaves no time for deliberation about whether to seek review. Evaluating appeal prospects must begin the day the order issues. The rule exists because certification frequently determines outcome before any final judgment, with certification creating settlement pressure and denial ending the case economically.
