An action was brought for the wrongful conversion of machine tools delivered under hire purchase agreements which contravened wartime statutory orders. The plaintiff established its legal title to the goods at issue without relying upon the illegal contract pursuant to which it had hired the goods to the defendant. A party to an illegality can recover by virtue of a legal or equitable property interest if, but only if, he can establish his title without relying on his own illegality. The court stated the general rule that a man’s right to possession of an article will be enforced notwithstanding the fact that the article came into his possession by reason of an illegal contract. ‘a man’s right to possess his own chattels will as a general rule be enforced against one who, without any claim of right, is detaining them or has converted them to his own use, even though it may appear from the pleadings, or in the course of the trial, that the chattels in question came into the defendant’s possession by reason of an illegal contract between himself and the plaintiff, provided that the plaintiff does not seek, and is not forced, either to found his claim on the illegal contract or to plead its illegality in order to support his claim.’ and ‘It must not be supposed that the general rule which we have stated is subject to no exception. Indeed there is one obvious exception, namely that class of cases in which goods claimed are of such a kind that it is unlawful to deal in them at all, as for example, obscene books. No doubt there are others, but it is unnecessary, and would we think be unwise, to seek to name them all or to forecast the decisions which would be given in a variety of circumstances which may hereafter arise’.
‘We are satisfied that no rule of law, and no considerations of public policy, compel the court to dismiss the plaintiffs’ claim in the case before us, and to do so would be, in our opinion, a manifest injustice.’
