“As I mentioned, I have no building renovation projects planned at the moment, and would be interested in the possibilities of restoring the small house and barn at Mellinzeath. 1. I imagine, indeed understand that you and your sons would be unwilling to sell the property, and also understand that you are concerned about retaining the water rights. My own objective would be to clear some of the undergrowth and suckers from the property, renovate the buildings as stores, and then in the long term apply for permission to rehabilitate the buildings as a house. To this end, I would like to suggest that I take a long lease of the property, over a timescale which would enable this to go ahead, and then have a sufficient period for renting out of the property to give me a return once the property were renovated. It is difficult to envisage how long this process would take, but it is my experience that this type of planning procedure should be approached slowly and carefully. I believe that I would need at least 15 years to ensure that the project was viable, and would suggest a rent based on the value or use of the woodland area surrounding the place, possibly related to a value per acre that seemed reasonable to you. You would retain water rights and access; I understand that there is no right of way through Tucoys, and believe that access would be necessary through Boswidjack. At the end of the period, there is a chance that you and your family would have obtained a renovated period house in a pleasant surrounding, which someone else had paid for. 2. It seems possible that you would not wish to consider any of the above, and that there was a case for your carrying out the above actions yourself. If this is the case, I would be happy to act on your behalf, prepare proposals in detail and sort the matter out. However, there would be a fee due for this, but I would be happy to discuss this further.”
“147.… Although me and my wife are the claimants in this claim, we were forced to issue these proceedings because, out of the blue, [the defendant] served us with notices to quit, with complete disregard to what was clearly a common understanding between us that: a) one day my wife and I (or alternatively my son) would buy [the property]; and b) in the meantime, we could continue as tenants indefinitely.”
“Subject to the following provisions of this section, an order under section 29 of this Act for the grant of a new tenancy shall be an order for the grant of a new tenancy of the holding…”
“29. … most scholars agree that the doctrine is based on three main elements, although they express them in slightly different terms: a representation or assurance made to the claimant; reliance on it by the claimant; and detriment to the claimant in consequence of his (reasonable) reliance…”
“The justice of an estoppel is not established by the fact in itself that a state of affairs has been assumed as the basis of action or inaction and that a departure from the assumption would turn the action or inaction into a detrimental change of position. It depends also on the manner in which the assumption has been occasioned or induced. Before anyone can be estopped, he must have played such a part in the adoption of the assumption that it would be unfair or unjust if he were left free to ignore it.”
“56. I would prefer to say (while conscious that it is a thoroughly question begging formulation) that to establish a proprietary estoppel the relevant assurance must be clear enough. What amounts to sufficient clarity, in a case of this sort, is hugely dependent on context. I respectfully concur in the way Hoffmann LJ put it in Walton v Walton [1994] CA Transcript Number 479… Hoffmann LJ stated, at para 16: ‘The promise must be unambiguous and must appear to have been intended to be taken seriously. Taken in its context, it must have been a promise which one might reasonably expect to be relied upon by the person to whom it was made’.” ‘The promise must be unambiguous and must appear to have been intended to be taken seriously. Taken in its context, it must have been a promise which one might reasonably expect to be relied upon by the person to whom it was made’.”
“35. In Willmott v Barber(1880) 15 Ch D 96 Fry J identified the essential elements of what has become known as estoppel by acquiescence in the following way: ‘In the first place the plaintiff must have made a mistake as to his legal rights. Secondly, the plaintiff must have expended some money or must have done some act (not necessarily upon the defendant's land) on the faith of his mistaken belief. Thirdly, the defendant, the possessor of the legal right, must know of the existence of his own right which is inconsistent with the right claimed by the plaintiff. If he does not know of it he is in the same position as the plaintiff, and the doctrine of acquiescence is founded upon conduct with a knowledge of your legal rights. Fourthly, the defendant, the possessor of the legal right, must know of the plaintiffs mistaken belief of his rights. If he does not, there is nothing which calls upon him to assert his own rights. Lastly, the defendant, the possessor of the legal right, must have encouraged the plaintiff in his expenditure of money or in the other acts which he has done, either directly or by abstaining from asserting his legal right. Where all these elements exist, there is fraud of such a nature as will entitle the Court to restrain the possessor of the legal right from exercising it, but, in my judgment, nothing short of this will do.’ [ … ] 38. The principles of proprietary estoppel, as they have developed since Willmott v Barber, were reviewed by Oliver J in Taylors Fashions Ltd v Liverpool Victoria Trustees Co Ltd[1982] QB 133 . A critical issue in Taylors Fashions was what needed to be shown about the state of knowledge of the party estopped. There were two aspects to this question. The first was whether the party estopped needed to know what his strict rights were. The second was whether the party estopped needed to know that the other party was acting in the belief that those strict rights would not be enforced against him. It was argued on behalf of the party resisting the existence of the estoppel that there was a clear distinction between cases of proprietary estoppel or estoppel by acquiescence on the one hand and promissory estoppel or estoppel by representation on the other hand. In the latter case, so it was argued, the state of mind of the promisor or representor was largely irrelevant (except to the extent of knowing, actually or inferentially that his representation was likely to be acted upon). In the former case, however, it was necessary that the party alleged to have acquiesced in or encouraged the other’s belief knew that other believed that the right of the party resisting the estoppel would not be enforced against him. 39. To determine what needed to be shown about the state of knowledge of the party estopped, Oliver J started with the judgment of Fry J in Willmott v Barber. Of this case he said: ‘It has to be borne in mind, however, in reading the judgment, that this was a pure acquiescence case where what was relied on was a waiver of the landlord’s rights by standing by without protest It was a case of mere silence where what had to be established by the plaintiff was some duty in the landlord to speak.’ 40. It was argued in Taylors Fashions that Fry J’s fourth probandum was not met, i.e. (i) knowledge by the possessor of the legal right of the other party's belief and (ii) knowledge that that belief is mistaken. As to the alternative approach of estoppel by representation, no representation was ever made, or if it was it was a representation of law. Oliver J said of that argument: ‘Now, convenient and attractive as I find Mr. Millett's submissions as a matter of argument, I am not at all sure that so orderly and tidy a theory is really deducible from the authorities - certainly from the more recent authorities, which seem to me to support a much wider equitable jurisdiction to interfere in cases where the assertion of strict legal rights is found by the court to be unconscionable. It may well be (although I think that this must now be considered open to doubt) that the strict Willmott v. Barber ... probanda are applicable as necessary requirements in those cases where all that has happened is that the party alleged to be estopped has stood by without protest while his rights have been infringed.’ 41. Oliver J went on to explain why this should be. In a pure acquiescence case, where all that is alleged is a standing by in silence: ‘... it is readily understandable that there must be shown a duty to speak, protest or interfere, which cannot readily be shown in the absence of knowledge or at least a suspicion of the true position.’ 42. On the other hand it was submitted for the party seeking to create the estoppel that the authorities did not support the absolute necessity for compliance with all five probanda (and in particular the requirement of knowledge on the part of the party estopped that the other party's belief is a mistaken belief) in cases where the conduct relied on has gone beyond mere silence and amounts to active encouragement. Thus it could be that the fostering of an expectation in the minds of both parties at the time but from which, once it has been acted upon, it would be unconscionable to permit the landlord to depart, could give rise to the estoppel. Oliver J said: ‘The fact is that acquiescence or encouragement may take a variety of forms. It may take the form of standing by in silence whilst one party unwittingly infringes another's legal rights. It may take the form of passive or active encouragement of expenditure or alteration of legal position upon the footing of some unilateral or shared legal or factual supposition. Or it may, for example, take the form of stimulating, or not objecting to, some change of legal position on the faith of a unilateral or a shared assumption as to the future conduct of one or other party. I am not at all convinced that it is desirable or possible to lay down hard and fast rules which seek to dictate, in every combination of circumstances, the considerations which will persuade the court that a departure by the acquiescing party from the previously supposed state of law or fact is so unconscionable that a court of equity will interfere.’ 43. This led Oliver J to conclude: ‘Furthermore the more recent cases indicate, in my judgment, that the application of the Ramsden v. Dyson... principle - whether you call it proprietary estoppel, estoppel by acquiescence or estoppel by encouragement is really immaterial - requires a very much broader approach which is directed rather at ascertaining whether, in particular individual circumstances, it would be unconscionable for a party to be permitted to deny that which, knowingly, or unknowingly, he has allowed or encouraged another to assume to his detriment than to inquiring whether the circumstances can be fitted within the confines of some preconceived formula serving as a universal yardstick for every form of unconscionable behaviour. So regarded, knowledge of the true position by the party alleged to be estopped becomes merely one of the relevant factors (it may even be a determining factor in certain cases) in the overall inquiry.’ (emphasis supplied) 44. I have laboured the case of Taylors Fashions at some length to demonstrate that Oliver J’s reference to “that which, knowingly, or unknowingly, he has allowed another to assume to his detriment” is deliberate. Whilst Oliver J was certainly not saying that questions of knowledge by the party estopped are not relevant – he says the opposite – they fall to be considered in the overall assessment of whether it is unconscionable to allow him to deny the interest which he has allowed or encouraged to believe in or to assume. 45. This final passage in Oliver J’s judgment was approved in general terms by Lord Walker in Cobbe v Yeoman‘s Row Management Ltd[2008] 1 WLR 1752 at 1779G- 1780B. In the course of his own judgment in that case Lord Walker made some other important observations. Firstly, at paragraph 54, he describes Plimmer v Wellington Corporation(1884) 9 App Cas 699 as a ‘common expectation case’. Mr Plimmer, a businessman of some substance, dealt with the provincial government, under arrangements attended by a high degree of informality. Lord Walker described the nub of the Privy Council’s decision in this way: ‘In the present case, the equity is not claimed because the landowner has stood by in silence while his tenant has spent money on his land. This is a case in which the landowner has, for his own purposes, requested the tenant to make the improvements. The Government were engaged in the important work of introducing immigrants into the colony. For some reason, not now apparent, they were not prepared to make landing-places of their own, and in fact they did not do so until the year 1863. So they applied to John Plimmer to make his landing-place more commodious by substantial extension of his jetty and the erection of a warehouse for baggage. Is it to be said that, when he had incurred the expense of doing the work asked for, the Government could turn round and revoke his licence at their will? Could they in July, 1856, have deprived him summarily of the use of the jetty? It would be in a high degree unjust that they should do so, and that the parties should have intended such a result is, in the absence of evidence, incredible.’ 46. Secondly, Lord Walker notes at paragraph 56 that Willmott v Barber: ‘calls for mention because Fry J's five probanda have over the years proved something of a stumbling-block in the development of equitable estoppel, until the position was clarified by Oliver J in Taylors Fashions Ltd v Liverpool Victoria Trustees Co Ltd (1979)[1982] QB 133 . Gray and Gray comment (para 10.204, footnote 1) that courts often tried to force factual situations into the probanda even when they were "ludicrously irrelevant or inapplicable" to the case.’ 47. Thirdly he pointed out with approval at paragraph 58 that Oliver J had explained: ‘the five probanda (including the defendant's knowledge of his own title, and of the claimant’s mistake as to title) are relevant only to cases of unilateral mistake, where the defendant's only encouragement to the claimant has been passive nonintervention’. 48. Fourthly Lord Walker, at paragraph 65, dealt with the difference between a party believing that he has a right and a party hoping, or even confidently expecting that he would be granted one. He noted however that the point that hopes were not enough came out most clearly in the commercial context, and surfaced less often in cases with a domestic or family flavour. 49. The following year in Thorner v Major[2009] UKHL 18 , Lord Walker commenced his judgment with the following, expressly approving the passage in an earlier edition of Megarry & Wade, Law of Real Property, to that which the judge in our case relied: ‘... most scholars agree that the doctrine is based on three main elements, although they express them in slightly different terms: a representation or assurance made to the claimant; reliance on it by the claimant; and detriment to the claimant in consequence of his (reasonable) reliance (see Megarry & Wade, Law of Real Property, 7th edition (2008) para 16-001; Gray & Gray, Elements of Land Law, 5th edition (2009) para 9.2.8; Snell’s Equity, 31st edition (2005) paras 10-16 to 10-19; Gardner, An Introduction to Land Law (2007) para 7.1.1).’ 50. It might have been thought that cases of pure acquiescence did not fit into that general formulation. However, Lord Walker explained at paragraph 55 that: ‘ ... if all proprietary estoppel cases (including cases of acquiescence or standing-by) are to be analysed in terms of assurance, reliance and detriment, then the landowner's conduct in standing by in silence serves as the element of assurance. As Lord Eldon LC said over 200 years ago in Dann v Spurrier (1802) 7 Ves 231, 235-236: "this Court will not permit a man knowingly, though but passively, to encourage another to lay out money under an erroneous opinion of title; and the circumstance of looking on is in many cases as strong as using terms of encouragement".’ 51. So far as the clarity of the assurance is concerned Lord Walker declined to lay down a hard and fast rule. He said at paragraph 56 that: ‘I would prefer to say (while conscious that it is a thoroughly question-begging formulation) that to establish a proprietary estoppel the relevant assurance must be clear enough. What amounts to sufficient clarity, in a case of this sort, is hugely dependent on context.’ 52. In support of his argument based on the fourth probandum in Willmott v Barber Mr Kokelaar relies on Brinnand v Ewens[1987] 19 HLR 415 . In that case the landlord, Mrs Brinnand, knew that the tenants of a flat in her house, Mr and Mrs Ewens, had moved into the whole house and expended money on repairs. The trial judge had held that Mrs Brinnand’s knowledge of the occupation and repairs did not mean that she knew that the work was done in expectation of a tenancy of the whole house. Nourse LJ, in deciding that this finding meant that Mrs Brinnand had not encouraged the Ewens' belief that they would have an interest in the whole property, said: ‘You cannot encourage a belief of which you do not have any knowledge.’ 53. I think it would be wrong to read too much into this dictum, particularly in the light of Oliver J’s recognition that it may be sufficient in some cases for someone “unknowingly” to cause someone to assume something. Brinnand v Ewens was a case in which it was not at all obvious that what the tenants were doing would require any right or interest in the landlord’s property. The landlord not only did not know that the tenant was acting on a belief that he would be granted a tenancy of the whole house, she had no means of knowing that either. In order to encourage a belief in those circumstances it may be correct to say that one must have at least constructive notice of it. But there will be other cases where it is self-evident that the acts which the tenant is doing, and of which the landlord is fully aware, necessarily require some right to be granted. If, therefore, I encourage a tenant to do acts which are only consistent with him having some right or interest on or over my property, so that he in fact believes that he has such a right, I can see no reason why it is not correct to say that I have encouraged him to believe or assume that he has the right. Of course whether a proprietary estoppel arises in such circumstances will depend on all the particular facts of the case. 54. Similarly, although some formulations of the rule speak of the party estopped having knowledge of the acts of detrimental reliance, this is not a requirement that is rigidly insisted on in cases of encouragement. Thus for example in Joyce v Epsom & Ewell Borough Council[2012] EWCA Civ 1398 , a case referred to in a passage from The Law of Proprietary Estoppel by Professor Ben McFarlane to which Mr Kokelaar referred us, Epsom & Ewell had encouraged Mr Joyce’s predecessor to believe that he would be able to gain access over a road. The trial judge refused to recognise a proprietary estoppel because it was not clear that the council was aware of the particular detriment on which the claimant relied, the moving of a garage and the construction of a drive. Davis LJ with whom Lord Dyson MR and Treacy LJ agreed, said this: ‘ ...I do not think that the alleged lack of knowledge on the part of the Council of the precise works actually undertaken by Mr Holborn can have the crucial significance the judge seems to have ascribed to it. As the judge had himself found, this was a case of encouragement, on which there was in fact detrimental reliance. It was known what Mr Holborn intended to do. It is not an invariable requirement in a case of this particular kind - indeed it is contrary to the flexible approach which the more recent authorities establish - that the person encouraging necessarily must know just what the person encouraged may have actually done in reliance on the encouragement: see, for example, Crabb v Arun District Council[1976] 1 Ch. 179 at p. 189 D-E (per Lord Denning MR) and at pp. 197H-198E (per Scarman LJ); and Taylor[s] Fashions at p.151 (per Oliver J). Mr Green himself very fairly accepted in argument that this could be so: he acknowledged that cases of encouragement are capable, depending on the circumstances, of standing in this respect on a different footing from cases based on acquiescence. But ultimately, of course, all depends on the particular facts of the individual case’.” ‘In the first place the plaintiff must have made a mistake as to his legal rights. Secondly, the plaintiff must have expended some money or must have done some act (not necessarily upon the defendant's land) on the faith of his mistaken belief. Thirdly, the defendant, the possessor of the legal right, must know of the existence of his own right which is inconsistent with the right claimed by the plaintiff. If he does not know of it he is in the same position as the plaintiff, and the doctrine of acquiescence is founded upon conduct with a knowledge of your legal rights. Fourthly, the defendant, the possessor of the legal right, must know of the plaintiffs mistaken belief of his rights. If he does not, there is nothing which calls upon him to assert his own rights.
