Duhaime's Law Dictionary Vacatur Definition: Latin: to set aside a judgment. For example, a successful appeal has the effect of rendering the judgment appealed vacatur; vacated; set aside. An application can also be made to the court explicitly requesting the relief of vacatur; seeking thus to set aside a court order. In United States v Williams, Justice Woods adopted these words as "correct as to the law": "... when a conviction is vacated, the effect is to nullify the judgment entirely and place the parties in the position of no trial having taken place at all, thus a vacated judgment is of no further force or effect."
