1978 (12) TMI 45 - SC - CST, VAT & Sales Tax

How far and to what extent is the State bound by the doctrine of promissory estoppel ?

Held that: We do not think that in order to invoke the doctrine of promissory estoppel it is necessary for the promisee to show that he suffered detriment as a result of acting in reliance on the promise. But we may make it clear that if by detriment we mean injustice to the promisee which would result if the promisor were to recede from his promise, then detriment would certainly come in as a necessary ingredient. The detriment in such a case is not some prejudice suffered by the promisee by acting on the promise, but the prejudice which would be caused to the promisee, if the promisor were allowed to go back on the promise.

It is true that taxation is a sovereign or governmental function, but, for reasons which we have already discussed, no distinction can be made between the exercise of a sovereign or governmental function and a trading or business activity of the Government so far as the doctrine of promissory estoppel is concerned. Whatever be the nature of the function which the Government is discharging, the Government is subject to the rule of promissory estoppel and if the essential ingredients of this rule are satisfied, the Government can be compelled to carry out the promise made by it. We are, therefore, of the view that in the present case the Government was bound to exempt the appellant from payment of sales tax in respect of sales of vanaspati effected by it in the State of Uttar Pradesh for a period of three years from the date of commencement of the production and was not entitled to recover such sales tax from the appellant. Appeal allowed.
