Origin
Latin for “of their own accord.” In law, the term describes a judge taking action without either party requesting it — such as dismissing a case or raising a legal issue unprompted. It’s also the motto of the U.S. Army’s 75th Ranger Regiment, reflecting the ethos of acting on one’s own initiative. The phrase captures authority exercised proactively rather than reactively.
