HL 25 April 2002. The appellants (TYP) sought to overturn earlier rulings that their claim for contribution against the defendants was precluded by the existence of an insurance policy in the joint names of the employer (CRS) and the contractor and by contractual provisions. "Held", appeal dismissed, as under the main contract clause Wimpey was not liable to pay compensation for loss and damage caused before practical completion, as any liability for failure to reinstate after the fire was separate and distinct from the liability for causing the fire. The Civil Liability (Contribution) Act 1976 s1(1) suggests liability is to be considered when contribution is being sought. The true basis of liability is to be found in determining the contract and not in the rules about circuitry of action as between co-insured.
