64 Lawton LJ said that, if the consent judgment had been satisfied, the plaintiffs would have had their remedy and could get no more. This suggests the rule against double satisfaction. It will be recalled that there was no room at common law for the operation of the rule against double satisfaction following satisfaction of a judgment in proceedings against joint tortfeasors, as distinct from concurrent tortfeasors, because the judgment against one joint tortfeasor without more released the other or others. With the changes in the common law worked by the LRUK Act, the rule against double satisfaction could operate following satisfaction of a judgment when there were joint tortfeasors as well as when there were concurrent tortfeasors. This, in my opinion, was the unexpressed (or barely expressed) basis for their Lordships' view.
65 Even when given multiple causes of action against joint tortfeasors, a plaintiff sues to recover the one loss in the case of joint tortfeasors just as in the case of concurrent tortfeasors. Whether as a common law rule or by what would now be called equitable principles of unjust enrichment, the prevention of double satisfaction would be mandated in the former case just as much as in the latter. What was said by Lord Hope in Jameson v Central Electricity Generating Board (1999) 1 All ER 193 at 201-2, although in relation to concurrent tortfeasors, applies equally to joint tortfeasors -
"The basic rule is that a plaintiff cannot recover more by way of damages than the amount of his loss. The object of an award of damages is to place the injured party as nearly as possible in the same financial position as he or she would have been in but for the accident. The liability which is in issue in this case is that of concurrent tortfeasors, because the acts of negligence and breach of statutory duty which are alleged against Babcock and the defendant respectively are not the same. So the plaintiff has a separate cause of action against each of them for the same loss. But the existence of damage is an essential part of the cause of action in any claim for damages. It would seem to follow, as a matter of principle, that once the plaintiff's claim has been satisfied by any one of several tortfeasors, his cause of action for damages is extinguished against all of them. As Lord Atkin said in Clark v Urquhart, Stracey v Urquhart (1930) AC 28 at 66: ' … damage is an essential part of the cause of action and if already satisfied by one of the alleged tortfeasors the cause of action is destroyed.' In that case the plaintiff had received in satisfaction of his claim against one defendant the full amount of damages which he could have received on any of the causes of action against the rest. It was held that his acceptance of the money paid into court was a satisfaction of all the claims in the action and that his damage, in a question with the other defendants, had been satisfied."
66 So his Lordship later said, with specific reference to Bryanston Finance Ltd v de Vries and satisfaction of a judgment (at 203) -
"I take as my starting point the fact that a claim of damages in tort is a claim for unliquidated damages. It remains unliquidated until the amount has been fixed either by the judgment of the court or by an agreement as to the amount which must be paid to satisfy the claim. It cannot be doubted that, once the amount of the damages has been fixed by a judgment against any one of several concurrent tortfeasors, full satisfaction will have been achieved when the judgment is satisfied. The law used to be that the judgment against one joint tortfeasor was itself, without satisfaction, a sufficient bar to an action against another joint tortfeasor for the same cause: Brown v Wootton (1604) Cro Jac 73, 79 ER 62, Brinsmead v Harrison (1872) LR 7 CP 547 and Bryanston Finance Ltd v de Vries (1975) 2 All ER 609 at 617-618 and 624-625, (1975) QB 703 at 721 and 730 per Lord Denning MR and Lord Diplock. In the case of concurrent tortfeasors, a judgment recovered against one of them did not put an end to the cause of action against any of the other tortfeasors until it had been satisfied: Bryanston Finance Ltd v de Vries (1975) 2 All ER 609 at 625, (1975) QB 703 at 730 per Lord Diplock. Section 6(1)(a) of the Law Reform (Married Women and Tortfeasors) Act 1935, which was replaced and extended by s 6 of the 1978 Act, altered the common law on these matters. As the law now stands, a plaintiff is barred from going on with a separate action against another tortfeasor if the judgment which he has obtained in the first action has been satisfied."
67 If the judgment against Mr Whitehead had been for damages assessed by the court, as distinct from a consent judgment for an amount agreed as part of the settlement, by the operation of the rule against double satisfaction the opponents would be precluded from continuing the proceedings against the claimant. The critical question, then, is whether the position is the same when the judgment against Mr Whitehead was a consent judgment for an amount agreed as part of the settlement.
68 In principle, the rule against double satisfaction should not operate, or should not necessarily operate, where the satisfied judgment is not for damages assessed by the court. The rationale for the rule is that, having been fully compensated for his loss, the plaintiff can not get more. Damages assessed by the court are by definition, as it were, full compensation for the plaintiff's loss. But an amount agreed as or as part of a settlement is not necessarily full compensation for the plaintiff's loss. Unless the settlement is in truth a capitulation, of its nature it will involve compromise, so that the amount is unlikely to be full compensation for the claimed loss and its relationship to the actual loss will be speculative. Further, the settlement may well be affected by matters not material to the assessment of the actual loss, such as the defendant's impecuniosity. Still in principle, only if it is found as a fact that the settlement amount was received as full compensation for the plaintiff's loss should the rule against double satisfaction operate to bar the plaintiff from proceeding against another tortfeasor or other tortfeasors.
69 In Bryanston Finance Ltd v de Vries Lord Denning MR considered that the consent judgment against Lord Carbery was "a sufficient bar to any claim for damages against Mr de Vries" (at 724), saying that it would be presumed that Lord Carbery had satisfied the judgment unless Mr de Vries proved otherwise. Diplock LJ would have found a defence if the consent judgment had been satisfied, but was not prepared to proceed on a basis contrary to the fact as told to the court. Lawton LJ would also have found a defence if the consent judgment had been satisfied, and thought that the trial judge had been wrong to enquire into the plaintiffs' intention to release Mr de Vries. The case may stand against the position in principle outlined in the previous paragraph of these reasons, and favour the claimant in the present case. But it does not seem that any attention was given to a distinction between damages assessed by the court and an amount agreed as or as part of a settlement.
70 In Ruffino v Grace Bros Pty Ltd (1980) 1 NSWLR 732 Master Allen applied the rule against double satisfaction following consent judgments. The Master said (at 734) -
"It is true that the amount of each of the judgments in the District Court was that arrived at by settlement, rather than by judicial determination. That does not matter. There is not a scintilla of evidence that the plaintiff received the payments otherwise than as full satisfaction; cf Carrigan v Duncan [1971 SLT 33]."
71 This is rather equivocal. Was there a finding of fact, in the absence of evidence to the contrary, that the settlement amounts were, or were intended by the plaintiff to be, full satisfaction? In Carrigan v Duncan 1971 SLT 33, there was an enquiry into the pursuer's intention in receiving a settlement amount for which judgment was given, see later in these reasons.
72 In Boyle v State Rail Authority (1997) 14 NSWCCR 374 the plaintiff settled with all but one of a number of concurrent tortfeasors and sought to continue against the remaining tortfeasor. It was assumed that judgment would be entered and there would be payment of the agreed amounts. Johns CCJ considered it necessary to examine "the circumstances surrounding the settlement", saying that there was a presumption that there had been full satisfaction but that "[w]ithout an inquiry into the facts, it is impossible for a court to say when an action is settled what sums short of the sum sued may or may not be appropriate as payment in full satisfaction of the claim" (at 379). He was not satisfied that the plaintiff had received the settlement amounts otherwise than as full compensation or satisfaction for his claim.
73 A related question was addressed in Jameson v Central Electricity Generating Board. It is directly relevant to the claimant's remaining argument, but the answer to the question is also of present assistance.
74 In Jameson v Central Electricity Generating Board the worker contracted mesothelioma from exposure to asbestos dust while working at the defendant's power stations. He sued his employer, and agreed to accept an amount "in full and final settlement and satisfaction of all the causes of action in respect of which the Plaintiff claims in the Statement of Claim". The settlement was given effect by a Tomlin order, so that the proceedings were stayed and no judgment was entered. The settlement amount was paid to the worker. Following the worker's death his executors sued the defendant on behalf of his widow under the Fatal Accidents Act 1976 (UK), and the defendant joined the employer as third party. One question was whether the settlement and payment of the settlement amount meant that the worker could not have sued the defendant, a concurrent tortfeasor with the employer. If he could not, his executors could not bring their proceedings.
75 The leading speech was that of Lord Hope, with which Lord Browne-Wilkinson and Lord Hoffmann agreed. Lord Clyde arrived at the same result as Lord Hope. Lord Lloyd delivered a dissenting speech. I have already set out some passages from the speech of Lord Hope.
76 After reference to the rule against doubt satisfaction, Lord Hope posed the presently material question (at 202) -
"So the first question which arises on the facts of this case is whether satisfaction for this purpose is achieved where the plaintiff agrees to accept a sum from one of the alleged concurrent tortfeasors which is expressed to be in full and final settlement of his claim against that tortfeasor, if that sum is less than the amount which a judge would have held to be the amount of the damages which were due to him if the case had gone to trial and the defendant had been found liable."
