Fiscal incentive rules may validly limit deferment to production above installed capacity where they do not contradict the policy.

A fiscal incentive under the Bihar Industrial Policy Resolution, 1989 was examined against Rule 3 of the Bihar Sales Tax Supplementary (Deferment of Tax) Rules, 1990, which explained incremental production as production over and above installed capacity. The court held that the policy did not confer a vested benefit on all output above the pre-expansion level, and the delegated rule validly clarified the scope of deferment without defeating the policy. In taxation matters the State has wider latitude to prescribe eligibility conditions, and the explanatory note was upheld as consistent with the policy. The challenge was also treated as belated, given the long-standing operation of the provision.

Issues: Whether the explanatory note to Rule 3 of the Bihar Sales Tax Supplementary (Deferment of Tax) Rules, 1990, limiting deferment to incremental production over and above installed capacity, was inconsistent with the Industrial Policy Resolution, 1989, and whether the petitioner was entitled to deferment of sales tax on production increased beyond its pre-expansion level.

Analysis: The policy framed a broad incentive for existing industrial units undertaking expansion, while the Rules made the mechanism workable by prescribing eligibility conditions and explaining incremental production as production over and above installed capacity. The Court held that the policy did not expressly guarantee benefit on all production above the pre-expansion level, and the Rules did not curtail any vested policy benefit. In taxation matters the State has wider latitude, and the delegated rule merely clarified the extent of the incentive without negating the policy. The challenge to the explanatory note was also considered belated, as the provision had remained in force for a long period and disturbing it would unsettle settled arrangements.

Conclusion: The explanatory note and Rule 3 were upheld as valid and not ultra vires the Industrial Policy Resolution, 1989. The petitioner was not entitled to deferment of sales tax beyond production over and above installed capacity, and the writ application failed.

Ratio Decidendi: Where a policy grants a fiscal incentive in broad terms, delegated rules may validly clarify the extent of the benefit if they do not contradict or withdraw the substantive policy benefit; in such cases, incremental production may be confined to production above installed capacity.
