“Section 140(1) of the Courts of Justice Act R.S.O. 1990, c.C.43, permits a judge to order that a person may not institute any further proceeding in any court except by leave if the Court is satisfied that the person has persistently and without reasonable grounds instituted vexatious proceedings in any court or conducted a proceeding in any court in a vexatious manner.
The purpose of s. 140(1) of the CJA is to prevent abuse of the court’s process. This is particularly relevant in family law matters where a party may continue to initiate repeated court proceedings as a form of harassment of a former spouse or partner.”
