Petition for Rehearing or Rehearing En Banc

A request that the court of appeals reconsider its decision, either by the same panel or by all the active judges sitting en banc. Under Rule 40 as amended in 2024, panel rehearing is the ordinary way to reconsider a panel decision, and rehearing en banc is not favored. En banc rehearing ordinarily will be allowed only if one of the criteria in Rule 40(b)(2) is met, such as a conflict with Supreme Court or circuit precedent or a question of exceptional importance.

When the petition for rehearing or rehearing en banc is used

Timing: after the court of appeals enters judgment. The petition is generally due within 14 days after entry of judgment. In a civil case, any party has 45 days if one of the parties is the United States, a federal agency, or a federal officer or employee sued in an official capacity or, in some cases, an individual capacity (Rule 40(d)(1)). The court may shorten or extend the time by order or local rule. Appeals follow a final judgment in most cases. The Federal Rules of Appellate Procedure govern this stage.

What the rule requires

  • A petition for panel rehearing must state with particularity each point of law or fact that the petitioner believes the court has overlooked or misapprehended.
  • A petition for rehearing en banc must begin with a statement that the decision conflicts with precedent or involves a question of exceptional importance (Rule 40(b)(2)).
  • Oral argument on whether to grant the petition is not permitted, and no response is permitted unless the court requests one (Rule 40(d)(4)-(5)).
  • If a timely petition is filed, the mandate generally issues 7 days after the order denying it (Rule 41(b)).

In practice, read each requirement closely. Then check whether your court adds anything of its own. For example, many courts set page limits, formatting rules or a duty to confer with the other side first.

  • En banc: french for "on the bench." A case heard by all the active judges of a court of appeals rather than by a panel of three.
  • Mandate: the formal order an appellate court sends to the lower court telling it the appeal has been decided and directing further action. In the federal courts of appeals, Federal Rule of Appellate Procedure 41 governs when the mandate issues.
