Sainsbury's Supermarkets Ltd v Mastercard Inc and other companies

Practice – Preliminary point of law. In the course of proceedings, the defendant companies made an application for an issue of ex turpi causa to be determined as a preliminary issue. The Chancery Division, in dismissing the application, held that, in all the circumstances, it would not be just and would not serve the overriding objective to order the issue of ex turpi causa to be tried as a preliminary issue.
