Pournami Oil Mills, Etc vs State Of Kerala & Anr on 19 December, 1986
10. It would have been possible for the respondents to contend that the concession or incentive or exemption from sales tax can be granted only by issue of a notification under section 9 of the Andhra Pradesh General Sales Tax Act and that G.O. No. 498 issued by the Department of Commerce and Industry could not amount to a valid notification under section 9 of the Act. After the decision of the Supreme Court in Pournami Oil Mills v. State of Kerala , even this submission cannot be successfully urged, because the Supreme Court has held that representation contained in a like Government order issued by an altogether different department has to be related to the power under the Sales Tax Act to grant exemption. The Supreme Court found the genesis of the power in section 10 of the Kerala General Sales Tax Act, eventhough the order granting concession as in the present case was issued by the Department of Commerce and Industry. We would have expected that if the statute confers a power and also prescribes the manner in which it has to be exercised, it should have been exercised in that prescribed manner and none other. But in its wisdom, the Supreme Court has chosen to discard that principle of law to grant relief on the basis of equitable estoppel in almost identical cases. We are bound by those decisions, though we would have decided otherwise on the basis of the wholesome principle that exercise of a statutory power in a manner different from that which is prescribed is not valid.
