Appellate Practice
Vacate
To formally annul or set aside a prior court order or judgment.
Plain-English definition
Vacatur is the appellate or trial court's act of nullifying a prior order or judgment, treating it as if it never existed. Distinct from reversal — a vacated order has no precedential effect, while a reversed order has been judged wrong.
