“(1) Even in a case where, on a sale of land, the vendor had stipulated that the sale shall be subject to stated possible encumbrances or prior interests, there is no general rule that the court will impose a constructive trust on a purchaser to give effect to them. (2) The court will not impose a constructive trust in such circumstances unless it is satisfied that the conscience of the estate owner is affected so that it would be inequitable to allow him to deny the claimant an interest in the property. (3) In deciding whether or not the conscience of the new estate owner is affected in such circumstances, the crucially important question is whether he has undertaken a new obligation, not otherwise existing, to give effect to the relevant encumbrance or prior interest. If, but only if, he has undertaken such a new obligation will a constructive trust be imposed. ”
“Since the basis of Lyus is showing that the conscience of the purchaser is affected, it might be argued that the apparatus of registration has no relevance to the question arising. In the Lyus case itself it had none, because nothing which the plaintiffs could have done could have protected their rights against the defendants. In a directly comparable case that might again be the case. But in a case such as the present, where the rights asserted are capable of protection on the register and where they are not referred to in the contract in specific but only in general terms, then it seems to me that the registration system is relevant. That is for at least two reasons. One is that, absent a specific reference in the contract, the purchaser may be thought to be entitled to rely on third parties protecting themselves in the manner provided for under the legislation. The other is that the contract provision will more readily be interpreted as intended to protect the vendor against a possible claim by the purchaser than as imposing a new personal obligation on the purchaser towards the third party”
