Practice – Summary judgment. The claimant brought proceedings, contending that it was entitled to payment of a success fee under the terms of an engagement under which it agreed to provide services to the defendant company. The issue was whether the claimant's right to payment of a success fee was conditional on proof that its activities were an effective cause of the success in question being achieved. The Commercial Court, in granting the claimant's application for summary judgment, held that, where the desired event had been achieved, the claimant was entitled to its fee without the need for further inquiry as to whether it had been an effective cause of that event.
