In this essay I will discuss how the doctrine of consideration is too firmly fixed to be conquered by promissory estoppel. The doctrine of cconsideration has been a necessary component in contract law for the last number of years. Without its presence within a case, agreement or settlement it will be deemed not legally enforceable. Consideration is to contact law as Elvis is to rock and roll: the King”.[footnoteRef:1]Over the years many individuals have brought cases to court on the basis of using promissory estoppel as a tool to attack the defendant. This essay discusses how promissory estoppel can only be used to protect the appellant and not as a form of attack.

The main problem with consideration is its inability to focus directly on rational interpretation of the intention of the parties rather than on the rules of consideration. therefore, many existing obligations cannot be legally enforced. In the famous case of “Central London Property Ltd V High Trees”[footnoteRef:5] the concept of promissory estoppel and consideration created a lot of legal uncertainty. Originally promissory estoppel was based on the interchange of promises, however in this case it was grounded on the dependence we create in others.

Promissory estoppel goes hand in hand with the doctrine of consideration as it allows the courts to impose promises that have been depended on even if the promise was not part of an exchange. Lord denning stated that “the doctrine of consideration is too firmly fixed to be overthr...
