What is an appellate jurisdiction

Appellate jurisdiction is the power of an appellate court to review, amend and overrule decisions of a trial court or other lower tribunal. Most appellate jurisdiction is legislatively created, and may consist of appeals by leave of the appellate court or by right. Depending on the type of case and the decision below, appellate review primarily consists of: an entirely new hearing a hearing where the appellate court gives deference to factual findings of the lower court; or review of particular legal rulings made by the lower court.
