"The house in question is 141, Thomas Street, Abertridwr, Mid- Glamorgan. It is registered in the name of the plaintiff Miss Stella Tinsley. She is the sole legal owner. She and the defendant Miss Kathleen Milligan were, to use the judge's expression, lovers for about four years, from 1984 to 1988. In the discussions they had during the course of their relationship, both the plaintiff and the defendant expressly recognised they were running a lodging house first at 9, Fitzhamon Embankment, Cardiff, and subsequently at Thomas Street, as a joint business venture and that the ownership of the respective houses was also on a joint basis.
". . . the underlying principle is the so-called public conscience test. The court must weigh, or balance, the adverse consequences of granting relief against the adverse consequences of refusing relief. The ultimate decision calls for a value judgment."
"The objection, that a contract is immoral or illegal as between plaintiff and defendant, sounds at all times very ill in the mouth of the defendant. It is not for his sake, however, that the objection is ever allowed; but it is founded in general principles of policy, which the defendant has the advantage of, contrary to the real justice, as between him and the plaintiff, by accident, if I may so say. The principle of public policy is this; ex dolo malo non oritur actio. No court will lend its aid to a man who founds his cause of action upon an immoral or an illegal act. If, from the plaintiffs own stating or otherwise, the cause of action appears to arise ex turpi causa, or the transgression of a positive law of this country, there the court says he has no right to be assisted. It is upon that ground the court goes; not for the sake of the defendant, but because they will not lend their aid to such a plaintiff. So if the plaintiff and defendant were to change sides, and the defendant was to bring his action against the plaintiff, the latter would then have the advantage of it; for where both are equally in fault, potior est conditio defendentis."
"There are many cases which show that when two persons agree together in a conspiracy to effect a fraudulent or illegal purpose - and one of them transfers property to the other in pursuance of the conspiracy - then, so soon as the contract is executed and the fraudulent or illegal purpose is achieved, the property (be it absolute or special) which has been transferred by the one to the other remains vested in the transferee, notwithstanding its illegal origin . . . The reason is because the transferor, having fully achieved his unworthy end, cannot be allowed to turn round and repudiate the means by which he did it - he cannot throw over the transfer. And the transferee, having obtained the property, can assert his title to it against all the world, not because he has any merit of his own, but because there is no one who can assert a better title to it. The court does not confiscate the property because of the illegality - it has no power to do so - so it says, in the words of Lord Eldon: 'Let the estate lie where it falls'; see Muckleston v. Brown 6 Ves. 52, 69."
". . . the plaintiff stating, he had been guilty of a fraud upon the law, to evade, to disappoint, the provision of the legislature, to which he is bound to submit, and coming to equity to be relieved against his own act, and the defence being dishonest, between the two species of dishonesty the court would not act; but would say, 'Let the estate lie, where it falls'."
"... the court looking at the quality of the illegality relied on by the defendant and all the surrounding circumstances, without fine distinctions, and seeking to answer two questions: first, whether there had been illegality of which the court should take notice and, second, whether in all the circumstances it would be an affront to the public conscience if by affording him the relief sought the court was seen to be indirectly assisting or encouraging the plaintiff in his criminal act."
"In so far as the basis of the ex turpi causa defence, as founded on public policy, is directed at deterrence it seems to me that the force of the deterrent effect is in the existence of the known rule and in its stern application. Lawyers have long known of the rule and must
"The reason for waiving any right Chiswell had in consequence of the manner, in which Nantes made this purchase, the object of keeping the ships registered in the name of Nantes, was, that a profit might be made by the employment of them in contracts with Government; and Chiswell was a Member of Parliament; who, the law says , shall not be a contractor. The moment the purpose to defeat the policy of the law by fraudulently concealing, that this was his property, is admitted, it is very clear, he ought not to be heard in this Court to say, that is his property."
"Two principles therefore stood in his way: first, that he had broken in upon the policy of the Act of Parliament; and could not be permitted to say, he had property of this nature, not subject to the regulations of the Act; and farther, that he had done so for the purpose of defeating another law; meaning to hold himself out not to be owner of those ships; as they were bound by contracts, of which he, being a Member of Parliament, could not have the benefit. Under those circumstances it could not possibly be contended, that he had that character of owner, which for his own private and fraudulent purpose he had disclaimed."
"A resulting, implied or constructive trust - and it is unnecessary for present purposes to distinguish between these three classes of trust - is created by a transaction between the trustee and the cestui que trust in connection with the acquisition by the trustee of a legal estate in land, whenever the trustee has so conducted himself that it would be inequitable to allow him to deny to the cestui que trust a beneficial interest in the land acquired. And he will be held so to have conducted himself if by his words or conduct he has induced the cestui
"Lord Hardwicke means to say, that, if the defendant admits the trust, though against the policy of the law, he would relieve: but if he does not admit the trust, but demurs, he would do, what does not apply in the least to this case; the plaintiff stating, he had been guilty of a fraud upon the law, to evade, to disappoint, the provision of the Legislature, to which he is bound to submit, and coming to equity to be relieved against his own act, and the defence being dishonest, between the two species of dishonesty the court would not act; but would say, 'Let the estate lie, where it falls.'"
"The moment the purpose to defeat the policy of the law by fraudulently concealing, that this was his property, is admitted, it is very clear, he ought not to be heard in this Court to say, that is his property. In the case of a bill filed to have a reconveyance of a qualification given by the plaintiff to his son to enable him to sit in Parliament, the purpose being answered, the Bill was very properly dismissed by Lord Kenyon with costs."
"It appears to their Lordships, however, that there is a clear distinction between Haigh v. Kaye and the present case. In Haigh v. Kaye the plaintiff conveyed a freehold estate to the defendant. In the conveyance it was stated that a sum of£850 had been paid by the defendant for it. The plaintiff proved that no such sum was paid and claimed that the defendant was a trustee for him. Now in that case the plaintiff had no reason to disclose any illegality and did not do so. It was the defendant who suggested that the transaction was entered into for a fraudulent purpose. He sought to drag it in without pleading it distinctly and he was not allowed to do so. But in the present case the plaintiff had of necessity to disclose his own illegality to the court and for this reason: He had not only to get over the fact that the transfer stated that the son paid$7,000 for the land, he also had to get over the presumption of advancement, for, whenever a father transfers property' to his son, there is a presumption that he intended it as a gift to his son; and if he wishes to rebut that presumption and to say that his son took as trustee for him, he must prove the trust clearly and distinctly, by evidence properly admissible for the purposes, and not leave it to be inferred from slight circumstances: see Shepherd v. Cartwright[1955] AC 431 , 445."
"[The plaintiff] did not have to found his cause of action on an immoral or illegal act. He was held entitled to recover. But in the present case the father has of necessity to put forward, and indeed, assert, his own fraudulent purpose, which he has fully achieved. He is met therefore by the principle stated long ago by Lord Mansfield 'No court will lend its aid to a man who founds his cause of action upon an immoral or an illegal act' see Holman v. Johnson (1775) 1 Cowp. 341, 343"
