Sales tax exemption withdrawal upheld as valid public-interest classification, and penalty sustained for omitted turnover returns.

A sales tax exemption for poultry feed and cattle-feed was validly withdrawn by amendment, and a later notification confining relief to specified units and co-operative societies was upheld as a public-interest classification with a rational basis, not a direct or immediate restraint on trade under Articles 301 and 304(a). The challenge to continued exemption therefore failed. Once the exemption stood withdrawn, assessees were bound to include poultry feed and cattle-feed turnover in their returns, and omission to do so justified penalty proceedings under section 45A of the Kerala General Sales Tax Act, 1963. The petitions were dismissed and no relief was granted.

Issues: (i) Whether the withdrawal of the earlier sales tax exemption for poultry feed and cattle-feed, and the grant of a limited exemption only to specified units under the later notification, was legally valid and enforceable; (ii) Whether the omission to include the turnover of poultry feed and cattle-feed in the returns attracted penalty under section 45A of the Kerala General Sales Tax Act, 1963.

Issue (i): Whether the withdrawal of the earlier sales tax exemption for poultry feed and cattle-feed, and the grant of a limited exemption only to specified units under the later notification, was legally valid and enforceable.

Analysis: The earlier exemption granted under S.R.O. 504/89 was specifically amended by S.R.O. 131/90 with effect from 2 February 1990, thereby omitting poultry feed and cattle-feed from its coverage. The later notification, S.R.O. 432/91, granted exemption only to specified units and co-operative societies. The challenge under Articles 301 and 304(a) failed because the concession was found to be a public-interest classification with a rational basis, and not a direct and immediate restraint on the freedom of trade. The distinction in favour of the Board and milk producers' co-operative societies was treated as a permissible economic incentive and not as unconstitutional discrimination.

Conclusion: The later notification was held valid, and the claim to continue the earlier exemption was rejected.

Issue (ii): Whether the omission to include the turnover of poultry feed and cattle-feed in the returns attracted penalty under section 45A of the Kerala General Sales Tax Act, 1963.

Analysis: Once the earlier exemption stood withdrawn, the petitioners remained liable to include the turnover of poultry feed and cattle-feed in their returns. Their failure to do so amounted to an omission attracting the penal proceedings initiated by the authorities. No ground was found to interfere with the action taken under section 45A.

Conclusion: The penalty proceedings under section 45A were upheld.

Final Conclusion: The petitions failed in entirety, and no relief was granted to the petitioners.

Ratio Decidendi: A sales tax exemption may be withdrawn or limited by a valid notification, and a concession based on public-interest differentiation does not offend Articles 301 or 304(a) unless it directly and immediately restricts trade.
