Operative
Operative: In effect and controlling. The operative complaint is the most recent pleading that governs the case, usually the latest amended complaint. Operative facts are the facts that give rise to a legal right or claim, and an operative provision is a part of a statute or contract that has legal effect, as opposed to a heading, recital or preamble.
