After a judgment is rendered by a trial judge or jury, the losing party has the right to have the decision reviewed by a higher court. Appellate practice, or appellate review, refers to the capacity of a higher court to examine or review the decision of a lower court for errors in judgment. Appellate procedure includes the rules and practices by which appellate courts evaluate the judgments of a trial court. Appellate review serves many functions in law, including: promoting equal justice, correcting errors of judgment committed by the trial court, and developing a precedent of law to be applied in future disputes.
