Promissory Estoppel

Introduction

Wherever a law is broken, a right of action is created in any person who has suffered a loss. This right to a remedy is enforced through the courts. In almost all cases, the state of the plaintiff's conscience will be irrelevant to obtaining relief. But, if the plaintiff has said or done something that induced the defendant to change his or her behaviour and that reliance was reasonable, the courts have a discretion to deny the remedy to the plaintiff. Hence, an estoppel is not a remedy at law in common law jurisdiction, but based on principles of equity. In the majority of cases, it is only a defence and it works by preventing a plaintiff from enforcing established legal rights, or from relying on a set of facts that would give rise to enforceable rights (e.g. words said or actions performed) if that enforcement or reliance would be unfair to the defendant. Because its effect is to defeat generally enforceable legal rights, the scope of the remedy is often very limited.

Origins

Promissory estoppel was developed by Lord Denning in Central London Property Trust Ltd. v. High Trees House Ltd. [1947] K.B. 130. Since then this case became an exemplary one for cases relevant to promissory estoppel.

In this case High Trees House Ltd obtained the tenancy of a block of flats in 1937 for a ground rent of Ј2500 per year. Unfortunately the luftwaffe played havoc with occupancy rates in central London after the outbreak of WW2. In January 1940 the plaintiff wrote to the High Trees confirming a reduction in rent to Ј1250. In September 1945 the receiver of the plaintiff company wrote saying that the rent must be paid at the full amount and demanding arrears. The conclusion of Lord Denning was: the full rent was payable from the time that the flats became fully occupied in early 1945, but that Central London could not go back on their promise of reduced rent for the period of the war because of High Trees reliance on the lower rate. 

Consideration

One of the other important elements of contract law is the requirement of consideration. One 1875 English case, Currie v. Misa, offered a definition of "consideration" which is still used:

".. some right, interest, profit or benefit accruing to the one party or some forbearance, detriment, loss or responsibility given, suffered or undertaken by the other."

As such, a contract differs from a gift. This also explains why you sometimes hear of very expensive objects sold for $1; which is done to ensure that what is essentially a gift, comes with the legal protection of contract law.

Under contract law, there is no contract if there is no consideration.

But consideration does not necessarily have to be quantified or quantifiable in monetary terms. Any discernible detriment to one of the parties could be that party's consideration. In one case, Hubbs v. Black, 1918, agreeing not to take a certain plot in a cemetery was considered to be ...
