This Practice Note, produced in partnership with Paul Wright of Selborne Chambers, considers summary judgment under CPR 24 (which decides a litigation claim or issue in a claim without a trial) and strike out under CPR 3.4 (which can result in a litigation party’s statement of case being struck out, either in full or in part, effectively bringing the substantive proceedings to an end). It briefly sets out who can apply for summary judgment and/or strike out, when such an application should be made, whether a party is restricted from making application in any particular circumstances, the court’s power to make an order on its own initiative and challenging orders made on the court’s own initiative.
