An appeal is a request to a higher court to review a decision made by a lower court. An appeal can be filed by either the plaintiff or the defendant in a case. The purpose of an appeal is to have the higher court correct any errors that may have been made by the lower court.
Appeals are important because they help to ensure that the justice system is fair and accurate. They also provide an opportunity for parties to a case to have their case heard by a different judge or panel of judges.
