A dismissal order ends the case. In bankruptcy, a dismissal is an order removing a case from the court’s docket, thereby also removing any protection of the law that the pending case might have occasioned, e.g., the automatic stay. A complete explanation of the effect of dismissal may be found in the Bankruptcy Code at 11 U.S.C. § 349.
