“In order to establish that the defendant has, by its conduct in the proceedings, submitted or waived its objection to the jurisdiction, it must be shown that it has taken some step which is only necessary or only useful if the objection has been waived or never been entertained at all. In Deutsche Bank AG v Petromena ASA191 the Court of Appeal held that there are two types of waiver which might give rise to a submission to the jurisdiction. First, there is “common law waiver”, which is the performance of an act which is inconsistent with maintaining a challenge to the jurisdiction. Such an act must clearly convey to the claimant and the court that the defendant is unequivocally renouncing its right to challenge the jurisdiction. In judging this, it is useful to consider whether a disinterested bystander with knowledge of the case would regard the acts of the defendant (or the defendant’s solicitor) as inconsistent with making and maintaining a challenge to the jurisdiction. Secondly, there can be a statutory form of submission to the jurisdiction, as in CPR, r.11(5) and (8), for example by filing an acknowledgment of service of proceedings, but then failing to make any application to dispute the court’s jurisdiction or failing in that application. In that situation the “disinterested bystander test” has no application; the sole issue is whether the conditions of those paragraphs have been met.”
