A formal judgment, decision, or decree made by a court or authority.
From Old French arret, from arrester 'to stop' or 'to settle.' Latin arrestum (past participle of arrestare) became the noun meaning a definitive stopping point—the court's final word.
You'll see 'arret' in old legal documents and in French law today—it's the kind of word that shows how English and French legal systems shared vocabulary, even as they developed differently.
