In layman's terms, certiorari (or "cert") is a formal request for a higher court, like the U.S. Supreme Court, to review a decision from a lower court, essentially saying, "Please send us the records and let us look at this case". It's the main way cases get to the Supreme Court because they don't have to hear every appeal; they choose which ones to take, often those involving significant legal questions or conflicts between courts, by granting (agreeing to hear) or denying (refusing to hear) the writ.

What does certiorari mean in simple terms?

Certiorari ("certiorari") is a legal order from a higher court to a lower court, demanding the records of a specific case for review, most famously used by the U.S. Supreme Court to decide which cases it will hear, often when a party seeks appeal after losing in lower courts, requiring at least four justices to agree to hear it (the "Rule of Four"). Derived from Latin meaning "to be informed," it allows higher courts to correct potential errors and ensure judicial oversight, essentially granting permission for an appeal.
