Which type of court reviews decisions made by lower courts?

The correct choice involves the function of an appellate court, which is specifically designed to review decisions made by lower courts. This court does not conduct trials or hear evidence; instead, it focuses on legal issues that may have arisen during the original case. The appellate court evaluates the record from the lower court, including transcripts of the trial, filings, and evidence presented, to determine if there were any legal errors that could have affected the outcome. It's an essential part of the judicial system, allowing for the correction of mistakes and ensuring that the legal process is followed correctly.

Other types of courts listed—such as district courts, supreme courts, and municipal courts—serve different purposes. District courts often handle the initial trial of cases, supreme courts may deal with appeals but often focus more on matters of significant legal or constitutional importance, and municipal courts generally handle local ordinance violations and minor offenses. This differentiation highlights the specialized role that appellate courts play in the judiciary system.
