enforceable as such. It is a concept fashioned by the courts, for judicial review of administrative action. It is procedural in character based on the requirement of a higher degree of fairness in administrative action, as a consequence of the promise made, or practice established. In short, a person can be said to have a “legitimate expectation” of a particular treatment, if any representation or promise is made by an authority, either expressly or impliedly, or if the regular and consistent past practice of the authority gives room for such expectation in the normal course. As a ground for relief, the efficacy of the doctrine is rather weak as its slot is just above “fairness in action” but far below “promissory estoppel”. It may only entitle an expectant: ( a ) to an opportunity to show cause before the expectation is dashed; or ( b ) to an explanation as to the cause for denial. In appropriate cases, the courts may grant a direction requiring the authority to follow the promised procedure or established practice. A legitimate expectation, even when made out, does not always entitle the expectant to a relief. Public interest, change in policy, conduct of the expectant or any other valid or bona fide reason given by the decision-maker, may be sufficient to negative the “legitimate expectation”. The doctrine of legitimate expectation based on established practice (as contrasted from legitimate expectation based on a promise), can be invoked only by someone who has dealings or transactions or negotiations with an authority, on which such established practice has a bearing, or by someone who has a recognised legal relationship with the authority. A total stranger unconnected with the authority or a person who had no previous dealings with the authority and who has not entered into any transaction or negotiations with the authority, cannot invoke the doctrine of legitimate expectation, merely on the ground that the authority has a general obligation to act fairly.”
