To put an end to a lawsuit. To quash or end a lawsuit. Pleas in abatement no longer exist in federal actions but many state courts still allow them to attack jurisdiction, process service, or for pending actions in other jurisdictions or courts. At common law when a suit abates the action is terminated. A new suit would have be brought for any further enforcement. In equity and in modern practice, an abatement is a present suspension of all proceedings in the suit because the proper parties are not capable of proceeding. The suit is then revived by a bill of revivor. Abatement puts an end to the suit. A stay of proceedings puts a suit in abeyance.
