ABSTRACT
It has been seen above that where action in reliance on a promise has been requested, there will usually be a sufficient consideration to justify the enforcement of the promise. But reliance may also justify judicial intervention in favour of the promisee by means other than through the use of the doctrine of consideration. In particular, the different varieties of estoppel have the effect of enforcing promises which induce reasonable reliance, but it is apparent that promises which are not supported by consideration have a much more limited effect than those which are so supported.
