Word of the Week: Vacate Proceedings

Vacate Proceedings. To nullify a chamber's previous action, such as the passage of a measure, adoption of an amendment or conference report, or an order for the yeas and neas; also referred to as vitiating an action. Requests to vacate proceedings require unanimous consent and are usually made to correct some inadvertent error in the proceedings.
