The Mercantile Court, in dismissing the defendant Swiss company's application to set aside service on it of a claim brought by the claimant German reinsurer, held that the claimant had a good arguable case that the English Court had jurisdiction, under art 23 of the Lugano Convention, because the claimant had contracted with the defendant on the basis of terms contained in a master agreement which provided for English law and the exclusive jurisdiction of the English Courts.
