In the course of argument in this Court, counsel for the respondent sought to rely upon two related arguments to raise a new case of an "equitable easement" protected by s 40(3)(e)(ii) of the Act. Both arguments were advanced in the context of the proposition that, immediately prior to the appellant's land being brought under the Act, it was subject to the burden of a common law easement appurtenant to the respondent's land. The first argument is that the failure to record the fact that the appellant's land was so burdened was an error which could, after registration, be corrected by the Recorder. The respondent was said to have an equitable right, as against the appellant, to have the error so corrected. That meant, so the argument proceeded, that the respondent's land enjoyed the benefit of an equitable easement which was protected by s 40(3)(e)(ii) of the Act. Alternatively, it was argued on behalf of the respondent that, in circumstances where the easement had existed at common law but by an omission was not recorded on the title when the land was brought under the Act, an equitable easement, protected by s 40(3)(e)(ii), existed by reason of doctrines of unjust enrichment or estoppel.
