Most decisions of a state or federal trial court (or an agency) are subject to review by an appeals court, including decisions regarding almost all types of civil cases. Whether the appeal concerns a judge's order or a final judgment entered by a jury, an appeals court reviews what happened in proceedings below for any errors of law. If the court finds an error that contributed to the trial court's decision, the appeals court will reverse that decision. The lawyers for the parties submit briefs to the court and may be granted oral argument. Once an appeals court has made its decision, the opportunity for further appeals is limited. The number of parties filing appeals has risen substantially in the last few decades, causing the state and federal court systems to implement changes in an effort to keep up.
