Siruv
In Jewish law, a shtar siruv (Hebrew: כתב סירוב; sometimes only siruv or spelled seruv) is a form of contempt of court order issued by a beth din (rabbinical court) in an effort to compel action by an individual. The siruv has been described as a form of cherem (which combines characteristics of shunning or excommunication) for a party who refuses to appear before a beth din.
