In a recent decision, the Court of Appeal upheld the effectiveness of Article 23(1) of the Judgments Regulation (Council Regulation No. 44/2001) by rejecting the proposition that a jurisdiction clause is defeated merely by a party raising a plausible allegation that the agreement in which the jurisdiction clause is contained is void as a result of mistake, misrepresentation, illegality, lack of authority and lack of capacity (Deutsche Bank v Asia Pacific Broadband Wireless Communications [2008] EWCA Civ 1091). The judgment emphasises the significance of the doctrine of separability in relation to jurisdiction clauses.
