Water cess on hydropower projects treated as an electricity-generation tax; levy struck down for lack of competence and excessive delegation.

A levy described as a water cess on hydropower projects was treated in substance as a tax on electricity generation because the charging scheme and rate fixation were linked to project head and generating potential, not to water drawn. The Court held that the State lacked legislative competence to impose such a levy under the relevant constitutional entries, and that the measure also burdened inter-State electricity supply impermissibly. It further found excessive delegation because the Act left rate fixation and the tax base to executive notification without adequate legislative policy or guidance. The levy, related rules and notices were struck down and the amounts collected were ordered to be refunded.

Issues: (i) Whether the levy styled as water cess was, in substance, a tax on generation of electricity and not on water drawn for hydropower generation; (ii) whether the State Legislature had competence to enact the levy under the constitutional scheme and the relevant entries in the Seventh Schedule; (iii) whether the charging provision and rate-fixing mechanism suffered from excessive delegation and absence of legislative guidance.

Issue (i): Whether the levy styled as water cess was, in substance, a tax on generation of electricity and not on water drawn for hydropower generation.

Analysis: The Act defined hydropower, user, water cess and water source in terms that linked the levy to water drawn for hydropower generation. The charging provision fastened liability on the registered user for water drawn for hydropower generation, while assessment and recovery were tied to the quantity of water drawn. The rate notification, however, calibrated the levy on the basis of the head of the project, which reflected the electricity-generating potential rather than the quantum of water drawn. The measure adopted by the State therefore indicated that the impost was intrinsically connected with electricity generation, and the reference to water was only incidental.

Conclusion: The levy was held to be, in substance, a tax on generation of electricity and not a true water cess, and this issue was decided in favour of the petitioners.

Issue (ii): Whether the State Legislature had competence to enact the levy under the constitutional scheme and the relevant entries in the Seventh Schedule.

Analysis: Entries dealing with water, land, land revenue and minerals were held not to sustain the impost because taxation entries are distinct from general regulatory entries, and the impugned levy did not answer the character of a tax on lands, buildings, mineral rights or land revenue. The Court held that the levy could not be justified under Entry 17, Entry 18, Entry 45, Entry 49 or Entry 50 of List II. Since the impost was in substance a levy on generation of electricity, the State lacked legislative competence to impose it, as the field of taxing electricity generation did not lie with the State. The Court also held that the levy had the effect of imposing an impermissible burden on inter-State supply of electricity.

Conclusion: The impugned enactment was held to be beyond the legislative competence of the State and ultra vires the Constitution, and this issue was decided in favour of the petitioners.

Issue (iii): Whether the charging provision and rate-fixing mechanism suffered from excessive delegation and absence of legislative guidance.

Analysis: The charging section authorised the Government to fix and vary the rate of cess by notification without laying down a legislative policy, standard or guiding principle. The Act also failed to identify the measure of tax with clarity, as the statutory scheme did not provide a definite base for computation of liability. The notification fixed tariff by reference to head, but that did not cure the absence of a proper legislative measure or the lack of guidance to the delegate. The framework thus left an essential component of the levy to executive discretion without adequate legislative control.

Conclusion: The charging and rate-fixing provisions were held to suffer from excessive delegation and lack of legislative guidance, and this issue was decided in favour of the petitioners.

Final Conclusion: The impugned levy and the connected rules and notices were struck down, the State was directed to refund the amounts collected, and the petitions were allowed on the grounds of lack of legislative competence and unconstitutional delegation.

Ratio Decidendi: Where the substance of a levy is on electricity generation rather than on the stated subject, the measure and charging scheme reveal its true character, and a State law imposing such a levy without constitutional competence or adequate legislative guidance is invalid.
