“It is relevant to notice that the amendments to Mr Cobbe’s pleaded prayer for relief, made when the specific performance and damages for breach of contract claims were abandoned, include the following: ‘(4). Alternatively a declaration that [the defendant company and Mrs Lisle-Mainwaring] are estopped from denying that [Mr Cobbe] has such interest in the property and/or the proceeds of sale thereof as the court thinks fit.’ This is the only pleaded formulation of the estoppel relied on by Mr Cobbe and, with respect to the pleader, is both meaningless and pointless.”
“Etherton J concluded, in paragraph 85 of his judgment, that the facts of the case ‘gave rise to a proprietary estoppel equity in favour of Mr Cobbe’, but nowhere identified the content of the estoppel. Mummery LJ agreed (paragraphs 60 and 61 of his judgment, concurred in by Dyson LJ (paragraph 120) and Sir Martin Nourse (paragraph 141), but he, too, did not address the content of the estoppel. Both Etherton J and Mummery LJ regarded the proprietary estoppel conclusion as justified by the unconscionability of Mrs Lisle-Mainwaring’s conduct. My Lords, unconscionability of conduct may well lead to a remedy but, in my opinion, proprietary estoppel cannot be the route to it unless the ingredients for a proprietary estoppel are present. These ingredients should include, in principle, a proprietary claim made by a claimant and an answer to that claim based on some fact, or some point of mixed fact and law, that the person against whom the claim is made can be estopped from asserting. To treat a “proprietary estoppel equity” as requiring neither a proprietary claim by the claimant nor an estoppel against the defendant but simply unconscionable behaviour is, in my respectful opinion, a recipe for confusion.”
“The preconditions for the application of proprietary estoppel are met only if and to the extent that the representee is left unconscionably disadvantaged by his reliance on the relevant assurance of entitlement. Only then does his change of position truly operate to his detriment. The minimal objective of estoppel doctrine is to neutralise any unacceptable prejudice which would otherwise flow from the representor’s departure from the assumptions engendered by his assurance of rights. Accordingly the element of ‘detriment’ which underlies all successful estoppel claims is ultimately measurable only in terms of whether it would be ‘unfair or unjust’ if the party who induced the expectation or assumed state of affairs were left free to ignore it. It must be shown that, by surrendering the representee to a subsisting and unremedied prejudice, the representor is ‘taking advantage of him in a way which is unconscionable, inequitable or unjust’.”
“In these circumstances, I conclude that the following principles apply where a party is seeking to call fresh evidence on a new point after judgment has been given but before the order has been drawn up: (1) the court has jurisdiction to grant an application to amend the pleadings to raise new points and/or to call fresh evidence and/or to hear fresh argument; (2) the court must clearly exercise its discretion in relation to such an application in a way best designed to achieve justice; (3) the general rules relating to amendment apply so that: (a) while it is no doubt desirable in general that litigants should be permitted to take any reasonably arguable point, it should by no means be assumed that the court will accede to an application merely because the other party can, in financial terms, be compensated in costs; (b) as with any other application for leave to amend, consideration must be given to anxieties and legitimate expectations of the other party, the efficient conduct of litigation, and the inconvenience caused to other litigants; (4) quite apart from, and over and above, those principles, because it is inherently contrary to the public interest and unfair on the other side that an unsuccessful party should be able to raise new points or call fresh evidence after a full and final judgment has been given against him, it would generally require an exceptional case before the court was prepared to accede to an application where the applicant could not satisfy the three requirements in Ladd v. Marshall ; (5) almost inevitably, each case will have particular features which the court will think it right to take into account when deciding how to dispose of the application before it; (6) the court should be astute to discourage applications which involve parties seeking to put in late evidence, but cases where new evidence is found after judgment is given and before the order is drawn up will be comparatively rare.”
“I cannot agree with this submission, which overlooks the fundamental difference in the principles applicable in a case where the argument before a judge is still open and continuing and a case where he has actually delivered judgment. In a case where the application to amend is made before delivery of judgment, the court has a wide discretion to permit amendment in the interests of justice, and, even at a late stage, will be disposed to exercise that discretion in favour of the applicant, subject to an appropriate order as to costs, if it considers that this is necessary to dispose of all the true issues arising between the parties. If the application is made after judgment, however, the situation is quite different because the applicant is then obliged to invoke the Barrell jurisdiction.”
“Since there must be some finality in litigation and litigants cannot be allowed unlimited bites at the cherry, it is not surprising that, according to the authorities, there are stringent limits to the exercise of the discretion conferred on the court by the Barrell jurisdiction. In that case itself [1973] 1 W.L.R. 19, Russell L.J., delivering the judgment of the Court of Appeal, said, at pp. 23-24: “When oral judgments have been given, either in a court of first instance or on appeal, the successful party ought, save in most exceptional circumstances, to be able to assume that the judgment is a valid and effective one.”
‘The cases to which we were referred in which judgments in civil courts have been varied after delivery … were all cases in which some most unusual element was present.’
“The matter cannot be looked at simply as a question of exercising a discretion to grant leave to amend. This must be so where a judge has pronounced judgment in favour of the defendants on a statement of claim, particularly where, as in this case, the judge has specifically enquired of the plaintiff's counsel during the hearing of the defendants' application that the action be dismissed and again when judgment was pronounced if such an amendment has been considered and was going to be sought and has been told that it has been considered and it has been decided not to seek such an amendment. Such an application must be subject to a more stringent test than would an application for leave to amend made during the hearing of the defendants' application and prior to judgment being given. The question is how that greater stringency is to be expressed? It is clearly not satisfactory for the plaintiff to be allowed to wait to see the outcome of the defendants' application and then, if the judge decides in the defendants' favour, to apply for an amendment. There must be some satisfactory reason for failure to apply for the amendment at the proper time. The proper time is either before the defendants' application is heard or during the hearing of the application.”
“I would adopt the approach of Neuberger J. in that case and apply it to the circumstances of the present case. There was a full and final judgment given against the plaintiff. There is no suggestion that the application of20 October 1999 came about because of the emergence of new evidence or new information. The court should require the party seeking to reopen the full and final judgment to demonstrate that it is an exceptional case or that there are strong reasons for doing so. The plaintiff did not begin to do that. Consequently the application should have been refused.”
