What Is a Petition for Rehearing?
A petition for rehearing is a formal request asking an appellate court to reconsider a decision it has already issued. In Idaho, this usually means asking the Idaho Supreme Court or Idaho Court of Appeals to take another look at its opinion because the party believes the court made an important legal or factual mistake.
Cornell Law School’s Legal Information Institute defines a rehearing as a later hearing based on a motion or appeal by one of the parties. In an appellate case, however, a petition for rehearing is usually much narrower than a new hearing or new trial. The appellate court is not starting the case over, hearing new witnesses, or reviewing new evidence. Instead, the court is being asked to reconsider its ruling based on the law, the appellate record, or the arguments already presented.
What Does “Appellate Court” Mean?
An appellate court is a court that reviews decisions made by a lower court. It does not usually decide who is telling the truth or hear new evidence. Instead, it looks at whether legal errors affected the outcome of the case.
In Idaho, appeals may be heard by the Idaho Supreme Court or the Idaho Court of Appeals, depending on the type of case and how the appeal is assigned.
When Might Someone File a Petition for Rehearing?
A petition for rehearing may be appropriate when the appellate decision appears to include a significant issue, such as:
- A mistaken statement of law
- A misunderstanding of the case record
- A factual statement that does not match what was presented on appeal
- A ruling based on an issue the parties did not fully argue
- An overlooked argument that could affect the outcome of the appeal
A petition for rehearing should not simply repeat the same arguments from the appeal. It should point to a specific legal or factual issue that may justify reconsideration. Federal appellate courts make the same general point: petitions for rehearing are not meant to reargue issues the court already considered and rejected.
How Long Do You Have to File a Petition for Rehearing in Idaho?
Timing is critical. Under Idaho Appellate Rule 42, a petition for rehearing must generally be physically filed with the Clerk of the Supreme Court within 21 days after the appellate opinion is filed.
If the court modifies its opinion in a meaningful way, a party may have another 21 days from the modified opinion to file a petition for rehearing.
A supporting brief or memorandum is generally due within 14 days after the petition is filed. In certain expedited appeals, the supporting brief must be filed at the same time as the petition.
Because these deadlines are strict, anyone considering a petition for rehearing should speak with an appellate attorney as soon as possible after the appellate court issues its opinion.
What Is a Supporting Brief?
A brief is a written legal argument submitted to the court. In the context of a petition for rehearing, the supporting brief explains why the court should reconsider its decision.
A strong supporting brief should usually identify the exact part of the opinion at issue, explain why that portion may be legally or factually incorrect, and show why the mistake matters to the outcome of the case.
Can the Other Side Respond?
Usually, the opposing party does not automatically get to file a response. Under Idaho Appellate Rule 42, no response to a petition for rehearing is allowed unless the appellate court specifically asks for one.
That means the petition and supporting brief need to be clear, focused, and persuasive. They may be the only written arguments the court reviews before deciding whether to grant or deny rehearing.
What Happens if the Court Grants Rehearing?
If the court grants a petition for rehearing, it will issue an order explaining what issues will be reheard. The court may also set a new briefing schedule or schedule oral argument.
Granting rehearing does not automatically mean the original decision will be reversed. It means the court has agreed to reconsider one or more issues before making a final decision.
Petition for Rehearing vs. Petition for Review
A petition for rehearing asks the same appellate court to reconsider its own decision.
A petition for review usually asks the Idaho Supreme Court to review a decision issued by the Idaho Court of Appeals. Under Idaho Appellate Rule 118, a party may petition the Idaho Supreme Court for review after a Court of Appeals decision. The Idaho Supreme Court has discretion to decide whether to accept the case for review.
These are different procedures with different purposes. In some cases, both options may be relevant, but the right approach depends on which court issued the decision, the deadlines involved, and the specific issues in the appeal.
Talk to an Idaho Appellate Attorney
A petition for rehearing is a specialized appellate filing with strict deadlines and a narrow purpose. It is not a chance to retry the case or introduce new evidence. It is a request for the appellate court to correct or reconsider a specific issue in its decision.
If you recently received an unfavorable appellate decision, you should act quickly. An attorney can review the opinion, compare it to the appellate record, and help determine whether there are valid grounds to ask the court to reconsider its ruling.
