In a recent article in the Cambridge Law Journal, Dr. D. M. Gordon, q.c., sets out systematically to demolish the theory of quasi-estoppel propounded by Denning J. in Central London Property Trust Ltd. v. High Trees House Ltd. In his closely reasoned argument he seeks to prove that no authority is to be found in case-law, either before or after 1947, to support any principle of this type, which he believes has been totally discredited by dicta in the later case of Tool Metal Manufacturing Co. Ltd. v. Tungsten Electric Co. Ltd. He further goes on to assert that the results of the implementation of such a principle would be arbitrary and undesirable in contrast with what he believes to be the clear rule of law laid down in the two nineteenth-century cases of Jorden v. Money and Foakes v. Beer. In short, it appears to be his view that a creditor who promises to forgo contractual rights without consideration and then subsequently retracts his promise and seeks to enforce his strict legal rights is both legally and ethically justified in doing so.
These are sweeping allegations which call for an answer. The object of this paper is to examine the validity of these arguments and to reassert that not only does authority exist to support a principle of quasi-estoppel of the type outlined by the writer on a previous occasion, but also to suggest that the implementation of this principle is most desirable if the rule of law is to be brought into line with commercial expectation and commercial practice.
