Rehearing
Rehearing: A second hearing of a case by the same court to reconsider its decision. In the federal courts of appeals, a party may petition for panel rehearing or rehearing en banc under Federal Rule of Appellate Procedure 40.

What rehearing means
Put simply, rehearing is part of the working vocabulary of a civil case. The short definition above covers the usual meaning. Still, a specific rule, statute or contract can give it a narrower meaning. For that reason, check how it is used in your own documents.
Where rehearing comes up
For example, the term appears in these procedures:
- Petition for Rehearing or Rehearing En Banc (Fed. R. App. P. 40): 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.

How to research the term
Start with the primary source. For example, if rehearing appears in a federal rule, read the rule itself and its official notes. After that, check your court’s local rules and any standing orders from the judge. In addition, search recent decisions from your own state or federal district. They show how courts read rehearing in practice. Because state rules often differ, our state procedures guide links to each state’s official rules. Above all, make sure the version you read is still in force.
