Principle of Promissory Estoppel Or Legitimate Expectation – A prior executive decision does not bar the State legislature from enacting a law or framing any policy contrary to or in conflict with the previous executive decision in furtherance of larger public interest. Nor can it be canvassed that the law laid down by the legislature would be hit by principle of promissory estoppel or legitimate expectation because earlier the executive had expressed its view differently- Promissory estoppel or legitimate expectation can be dealt with on the same status of the executive decision when the prior as well as the subsequent decisions are both taken by the same or similarly placed authorities. Where the executive takes a decision based upon which a party acts and, later on, the executive withdraws that decision to the detriment of the party acting upon the earlier decision, it can be said to be estopped from withdrawing its promise or depriving the party from its legitimate expectation of what had been promised- If the previous executive decision is withdrawn, modified or amended in any manner in exercise of legislative power in larger public interest, then the earlier promise upon which the party acts, cannot be enforced as a right and neither can the authorities be estopped from withdrawing its promise, as such an expectation does not give any enforceable right to the party. (Para 25-27)
