What is an appellate court's role when a writ of certiorari is granted?

When a writ of certiorari is granted, the appellate court's primary role is to review the record of the lower court. This means the court examines the proceedings and the decisions made in the lower court to ensure that proper legal standards were applied and that there were no significant errors in the handling of the case. The appellate court does not retry the case or hear new evidence; it strictly evaluates the existing record to determine if the lower court's rulings were appropriate based on the law and the facts presented during the initial trial. This process is critical in maintaining the integrity of the judicial system, as it allows for oversight of lower courts without re litigating the issues that have already been decided.
