"I agree with Mr Owen, however, that the terms of the settlement between the defendant and Newalls are not relevant to the task which it is the duty of the judge to perform, that is, to apportion responsibility for the damage in question as between the three parties."
"His task is the same whether Newalls is a defendant in the action, a third party brought in by Cape, or not a party at all. The judge will assess the evidence which the parties to the action choose to call but, on the basis of that evidence, apportion responsibility as between the claimant, Cape and Newalls. It will involve assessing Newalls's responsibility, because, in the present context, Cape will only be responsible for that share which is the responsibility neither of the claimant nor of Newalls. The claimant and Cape are entitled to call evidence to prove Newalls' share. The position is the same in contract as under the 1978 Act because, under the contract pleaded, Cape is liable to indemnify the claimant only for loss and damage arising "by reason of any breach of duty (statutory contractual common law) on the part of the defendant, (Cape) its servants or agents.
