Strict construction of sales tax exemption rules required fresh scrutiny of eligibility certificate limits and product scope.

Exemption provisions under rule 28A of the Haryana General Sales Tax Rules must be strictly construed, and an eligibility certificate confined to monochrome monitors and black-and-white TV sets could not be expanded without examining the rule's express limits on product identity, capital investment and the distinction between new units and expansion or diversification. The High Court had not addressed those statutory constraints and relied on irrelevant considerations, so the matter required fresh determination on the true scope of the rule. The appeal was allowed, the High Court judgment was set aside, and the writ petition was restored for decision afresh in accordance with law.

Issues: Whether colour monitors could be added to an eligibility certificate issued under rule 28A of the Haryana General Sales Tax Rules, 1975, which was confined to the manufacture of monochrome monitors and black-and-white TV sets.

Analysis: Rule 28A(2)(d) defines expansion or diversification by reference to additional manufacturing facilities for the same product in the case of expansion and different products in the case of diversification. In exemption matters, the rule is to be construed strictly. The High Court had not examined the effect of the words "for manufacture of the same product", the ceiling on capital investment fixed in the original eligibility certificate, or the operation of sub-rule (4)(a) prescribing different tax benefits and exemption periods for new units and expansion or diversification. Its decision rested mainly on the existence of a modified eligibility certificate and on an earlier case decided on laches, both of which were irrelevant to the proper interpretation of the rule.

Conclusion: The question was not correctly adjudicated by the High Court, and the matter required fresh determination on the true scope of rule 28A.

Final Conclusion: The appeal was allowed, the High Court judgment was set aside, and the writ petition was restored to the High Court for decision afresh in accordance with law.

Ratio Decidendi: Exemption provisions governing eligibility certificates must be strictly construed, and relief cannot be granted without examining the express statutory limits on the class of product, capital investment, and the scope of the relevant rule.
