When would a person go to a court with appellate jurisdiction?

A person would go to a court with appellate jurisdiction when they seek to challenge a decision made by a lower court. This typically occurs after a trial or hearing, where the individual believes that legal errors affected the outcome of their case. The appellate court reviews the record of the lower court proceedings to determine if the law was applied correctly and whether the rights of the parties were upheld. It does not conduct a new trial but rather evaluates the legal arguments presented in briefs and oral arguments.
