Default of third party; etc.
5.—(1) If a third party does not enter an appearance or, having been ordered to serve a defence, fails to do so.
(a)he shall be deemed to admit any claim stated in the third party notice and shall be bound by any judgment (including judgment by consent) or decision in the action in so far as it is relevant to any claim, question or issue stated in that notice; and
(b)the defendant by whom the third party notice was issued may, if judgment in default is given against him in the action, at any time after satisfaction of that judgment and, with the leave of the Court, before satisfaction thereof, enter judgment against the third party in respect of any contribution or indemnity claimed in the notice, and, with the leave of the Court, in respect of any other relief or remedy claimed therein.
(2) If a third party or the defendant by whom a third party notice was issued makes default in serving any pleading which he is ordered to serve, the Court may, on the application by summons of that defendant or the third party, as the case may be, order such judgment to be entered for the applicant as he is entitled to on the pleadings or may make such other order as may appear to the Court necessary to do justice between the parties.
(3) The Court may at any time set aside or vary a judgment entered under paragraph (1)(b) or paragraph (2) on such terms (if any) as it thinks just.
