"(1) The claimant may obtain judgment in default of an acknowledgment of service only if – (a) the defendant has not filed an acknowledgment of service or a defence to the claim (or any part of the claim); and (b) the relevant time for doing so has expired."
“36. The next point that is taken is that the condition in Rule 12.3(1)(a) is not satisfied because the First Defendant has filed an acknowledgment of service, albeit late and without, as I have decided, it being appropriate to grant an extension of time. Mr. Harding referred me to some dicta of Blair J in ESR Insurance Services Ltd. v. Clemons & Ors. That was a case in which, on the facts, Blair J granted an extension of time and therefore the point now under consideration did not arise, although he expressed himself as saying he had some doubt as to whether a default judgment could be entered where there had in fact been an acknowledgment of service, albeit late. 37. In my view, there are potentially two answers to this point the first of which is decisive. The relief to which the claimant is entitled must be judged by reference to the date of the application. At that time, Rule 12.3 was indisputably fulfilled because there had been no acknowledgment of service then entered and time had expired. In my view, a defendant cannot defeat a claimant's entitlement to relief at the date on which the application is made by subsequently serving an acknowledgment of service outside the time allowed for by the rules, in circumstances where there has been no extension of time, a fortiori where there has been an application for an extension of time which has been refused. That is sufficient of itself to dispose of the point. Secondly, there is much force in the argument that what is meant in Rule 12.3 by an acknowledgment of service is a timeous acknowledgement of service; if so even in circumstances (which are not the circumstances of this case) in which an application for judgment in default of acknowledgment of service is made after an acknowledgment of service has been served out of time, Rule 12.3 would be fulfilled in the absence of any extension of time by the court.”
