Official Gazette publication is mandatory for statutory exemption orders; estoppel cannot override a contrary legal scheme.

Publication in the Official Gazette was mandatory for an exemption order under section 11 of the Andhra Pradesh Non-Agricultural Lands Assessment Act, 1963, because statutory publication was part of the making of the order in a conditional legislation scheme. The separate requirement of laying before the Legislature was directory, so non-laying did not by itself invalidate the exemption. A later statutory notification could validly grant retrospective exemption within the statutory framework and supersede an earlier non-statutory Government Order. Promissory estoppel and legitimate expectation could not enforce a representation that conflicted with mandatory statutory requirements.

Issues: (i) whether an exemption order under section 11 of the Andhra Pradesh Non-Agricultural Lands Assessment Act, 1963 could be treated as valid without publication in the Official Gazette and without being laid before the Legislature; (ii) whether the later statutory notification validly granted retrospective exemption and superseded the earlier non-statutory Government Order; and (iii) whether promissory estoppel or legitimate expectation could be invoked to enforce the earlier Government Order.

Issue (i): whether an exemption order under section 11 of the Andhra Pradesh Non-Agricultural Lands Assessment Act, 1963 could be treated as valid without publication in the Official Gazette and without being laid before the Legislature

Analysis: The power under section 11 was treated as a power of conditional legislation exercised only in the manner prescribed by the statute. Since the statute expressly required publication in the Official Gazette, that requirement was held to be integral to the making of the order and not a mere matter of information. The Official Gazette publication was treated as the authoritative and conclusive form of promulgation. By contrast, the requirement of laying under section 11(2) was considered a form of simple laying and therefore directory, not mandatory.

Conclusion: Publication in the Official Gazette was mandatory and the earlier unnotified order was not validly made under section 11, but non-laying did not by itself invalidate an exemption order.

Issue (ii): whether the later statutory notification validly granted retrospective exemption and superseded the earlier non-statutory Government Order

Analysis: The exemption power was held capable of being exercised retrospectively so long as the period of exemption was within the statutory framework and after the commencement of the Act. The later notification, issued under section 11(1), was held to be statutory in character and to operate from the retrospective date specified by it. Because it covered the same subject and period, the earlier non-statutory order could not survive consistently alongside the later statutory order.

Conclusion: The retrospective notification was upheld as valid, and the appellant could claim exemption only under that notification.

Issue (iii): whether promissory estoppel or legitimate expectation could be invoked to enforce the earlier Government Order

Analysis: The doctrine of estoppel was held not to operate against a statutory mandate or to validate an act done in violation of mandatory statutory requirements. An executive representation that is itself contrary to the statute cannot be treated as a binding promise capable of defeating the law. The plea of legitimate expectation also could not prevail where the field was occupied by mandatory statutory provisions.

Conclusion: The pleas of promissory estoppel and legitimate expectation were rejected.

Final Conclusion: The appeals failed because the earlier exemption order was not validly made under the statute, the later statutory notification was upheld, and equitable doctrines could not override the statutory scheme.

Ratio Decidendi: Where a statute expressly requires publication of an exemption order in the Official Gazette, that requirement is mandatory in a conditional legislation framework, and an executive representation made contrary to the statute cannot be enforced through promissory estoppel.
