Definition - What does Appeal mean?
An appeal, in the context of the law, refers to the process of reviewing a case within the judicial system. In order for a plaintiff or a defendant to be granted an appeal, something substantively wrong must have occurred at the trial court. A party simply asserting that it does not agree with the trial court ruling is not sufficient grounds for appeal.
Justipedia explains Appeal
Most jurisdictions contain trial courts, a court of appeals, and supreme courts. Both the court of appeals and supreme courts hear appeals. In fact, any court that hears a case for the second or more time is considered an appeals court. As earlier explained, only in certain circumstances can a party appeal its case. These circumstances are called grounds for appeal. One example of a ground for appeal would be juror misconduct.
