"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."
“(1) A court does not have jurisdiction to hear and determine an action for defamation brought against a person who was not the author, editor or publisher of the statement complained of unless the court is satisfied that it is not reasonably practicable for an action to be brought against the author, editor or publisher.”
"On such an application, the Court will enter 'such judgment as it appears to the court that the claimant is entitled to on his statement of case':CPR 23.11 (1). This enables the Court to proceed on the basis of the claimant's unchallenged particulars of claim, which is normally the right approach, as evidential examination of the merits will usually involve unnecessary expenditure of time and resources and hence be contrary to the overriding objective: Sloutsker v Romanova [84], Brett Wilson v Persons Unknown [18]. Both those judgments contain some discussion of the possibility of departing from that normal approach. But I see no reason to do so here."
