We do not find any infirmity, much less any perversity, warranting any interference by this Court. However, there is one aspect which requires clarification.

Doctrine of Legitimate Expectation does not always result in relief. A protection of legitimate expectation is subject to overriding public interest. Even if an individual’s expectation is reasonable and based on a past practice or representation by Executive or Legislature, it can be denied if justified by a significant public necessity. Judiciary affords considerable leeway to Executive and Legislature in matters of economic policy. Consequently, previous policies do not bind Government indefinitely; new policies can be adopted, if deemed necessary, for public good. Nor can it be canvassed, law laid down by Legislature would be hit by Principle of Promissory Estoppel or Legitimate Expectation because earlier Executive had expressed its view differently.
