"Procedure for Dispute in 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. 11(2) A defendant who wishes to make such an application must first file an acknowledgement of service in accordance with Part 10. 11(3) A defendant who files an acknowledgement of service does not, by doing so, lose any right that he may have to dispute the court's jurisdiction. 11(4) An application under this rule must - (a) be made within 14 days after filing an acknowledgement of service; and (b) be supported by evidence. 11(5) If the defendant - (a) files an acknowledgement 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."
'… was incompetent at the date when the writ was issued, and that the doctrine of the relation back of an administrator's title to his intestate's property to the date of the intestate's death when the grant has been obtained cannot be invoked so as to render an action competent which was incompetent when the writ was issued.'
'As to the law, so far as this court is concerned it seems to me to be settled by Ingall v Moran and Hilton v Sutton Steam Laundry and, I may add, by Burns v Campbell, that an action commenced by a plaintiff in a representative capacity which the plaintiff does not in fact possess is a nullity, and, further, that it makes no difference that the claim made in such an action is a claim under the Fatal Accidents Acts which the plaintiff could have supported in a personal capacity as being one of the dependants to whom the benefit of the Acts extends.' 17 Before coming to Part 19.8(1), I should refer to what this court said about Ingall in Haq v Singh and another[2001] EWCA Civ 957 ;[2001] 1 WLR 1594 . The point there in issue arose underCPR Part 17.4 , a rule made under the provisions ofsection 35 of the Limitation Act 1980 and which, by its own terms, expressly applies only to cases where a period of limitation has expired. Part 17.4 provides, so far as material, that: '(1) This rule applies where – (a) a party applies to amend his statement of case in one of the ways mentioned in this rule; and (b) a period of limitation has expired … (4) The court may allow an amendment to alter the capacity in which a party claims if the new capacity is one which that party had when the proceedings started or has since acquired.' 18 In Haq a discharged bankrupt brought in 1993 a claim for damages, whereas the relevant cause of action had upon her bankruptcy vested and remained in her trustee. An amended defence served in 2000 asserted her lack of capacity to sue, whereupon she obtained an assignment from her trustee of the cause of action. The issue was whether the judge was right to permit her to amend to plead the assignment. He had so held on the basis that before the assignment she had no capacity to sue, whereas after the assignment she had the capacity to sue as the trustee's assignee and therefore the case was within Part 17.4(4). This court allowed the defendants' appeal, holding that since both before and after the assignment the claimant was suing in a personal capacity, her capacity had not altered and so she was not entitled to amend. Arden LJ, however, also expressed the obiter view, at paragraph [22], that: '
“20 Mr Millett’s primary proposition remains, however, that no amendment can be made to introduce a cause of action arising out of facts occurring subsequent to the commencement of proceedings, where at the date of their commencement no cause of action existed so that the claim as originally issue was “incurably bad”
