“… the principles applicable to the assertion of an estoppel by convention arising out of non-contractual dealings, to be derived from Keen v Holland, and the cases which comment upon it, are as follows: i) It is not enough that the common assumption upon which the estoppel is based is merely understood by the parties in the same way. It must be expressly shared between them. ii) The expression of the common assumption by the party alleged to be estopped must be such that he may properly be said to have assumed some element of responsibility for it, in the sense of conveying to the other party an understanding that he expected the other party to rely upon it. iii) The person alleging the estoppel must in fact have relied upon the common assumption, to a sufficient extent, rather than merely upon his own independent view of the matter. iv) That reliance must have occurred in connection with some subsequent mutual dealing between the parties. v) Some detriment must thereby have been suffered by the person alleging the estoppel, or benefit thereby have been conferred upon the person alleged to be estopped, sufficient to make it unjust or unconscionable for the latter to assert the true legal (or factual) position.”
“First, A makes a false representation of fact to B… Second, in making the representation, A intended or knew that it was likely to be acted upon. B, believing the representation, acts to its detriment in reliance on the representation. Fourth, A subsequently seeks to deny the truth of the representation. Fifth, no defence to the estoppel can be raised by A.”
“33.. The party seeking rectification must show that: (1) the parties had a common continuing intention, whether or not amounting to an agreement, in respect of a particular matter in the instrument to be rectified; (2) there was an outward expression of accord; (3) the intention continued at the time of the execution of the instrument sought to be rectified; (4) by mistake the instrument did not reflect that common intention.”
