What does the process of "certiorari" require from higher courts?

"Certiorari" is a legal term used primarily within the context of the judiciary that refers to a higher court's authority to review the decisions of lower courts. When a higher court grants a writ of certiorari, it is essentially agreeing to examine the records and decisions from a lower court to determine if there were any legal errors that warrant correction.

This process allows the higher court to ensure that the law is applied consistently and correctly across different jurisdictions and cases. The aim is not to create new laws or reinterpret existing ones but to ensure that the legal principles were followed in the original case. Additionally, the higher court does not retake the case in full or perform a new trial; instead, it looks at the documentation and arguments presented in the lower court to make its determination. The process does not involve the appointment of judges either, as that is unrelated to the certiorari proceedings. The focus is on the evaluation of prior decisions rather than initiating new legal proceedings or making administrative changes within the judicial system.
