‘Procedure for disputing the court’s jurisdiction 11 (1) A defendant who wishes to – (a) dispute the court’s jurisdiction to try the claim; or (b) argue that the court should not exercise its jurisdiction may apply to the court for an order declaring that it has no such jurisdiction or should not exercise any jurisdiction which it may have. (2) A defendant who wishes to make such an application must first file an acknowledgment of service in accordance with Part 10. (3) A defendant who files an acknowledgment of service does not, by doing so, lose any right that he may have to dispute the court’s jurisdiction. (4) An application under this rule must – (a) be made within 14 days after filing an acknowledgment of service; and (b) be supported by evidence. (5) If the defendant – (a) files an acknowledgment of service; and (b) does not make such an application within the period specified in paragraph (4), he is to be treated as having accepted that the court has jurisdiction to try the claim.’ 5.9 The Claimant relies upon Hoddinott v Persimmon Homes (Wessex) Ltd [2008] 1 W.L.R. 806 where the Court of Appeal held that a defendant is treated as having accepted that the court should deal with this claim, even if the time for service of the claim form should not have been extended, if the defendant had not complied with the requirements ofCPR Part 11 . Whilst I note that the failure in Hoddinott was to comply withCPR 11 (4), the following part of the judgment of Dyson LJ obviously applies where there is a failure to comply withCPR 11 (2): ‘26. … the language ofCPR r 11 is clear. Paragraph (1) permits a defendant to apply to the court for an order declaring that the court has no jurisdiction to try the claim or that the jurisdiction should not be exercised. Paragraph (2) provides that a defendant who wishes to make such an application “must first file an acknowledgment of service in accordance with Part 10 ” (emphasis added). Paragraph (4) provides that an application underCPR r 11 must be made “within 14 days after filing an acknowledgement of service” (again, emphasis added). Paragraph (5) provides that if the defendant files an acknowledgement of service and does not make an application within the period specified in paragraph (4), “he is to be treated as having accepted that the court has jurisdiction”. 27. In our judgment, the meaning of paragraph (5) is clear and unqualified. If the conditions stated in sub-paragraphs (a) and (b) are satisfied, then the defendant is treated as having accepted that “the court has jurisdiction to try the claim”. The conditions include that the defendant does not make an application for an order pursuant toCPR r 11 (1) within 14 days after filing an acknowledgment of service. An application to set aside an order extending the time for service made before the filing of an acknowledgement of service is not an application underCPR r 11 (1) nor is it an application made within 14 days after the filing of the acknowledgment of service…. 28. In our view, a defendant is fixed with the consequences stated in paragraph (5) if the two stated conditions are satisfied….’
