State Legislature lacks competence to tax electricity generation; delegation of tax rate fixation without guidelines is unconstitutional.

The State of Uttarakhand enacted the "Uttarakhand Water Tax on Electricity Generation Act, 2012," imposing a tax on "users" drawing water for hydroelectric power

Hydropower companies challenged the Act’s constitutional validity, arguing the State lacked legislative competence as the tax was effectively on electricity generation

A Division Bench of the Uttarakhand High Court delivered a split verdict on 25.10.2023

The Chief Justice upheld the Act, tracing power to the drawal of water (non-taxing entries), while the companion Judge struck it down as a tax on electricity generation

The matter was referred to a third judge (Justice Alok Kumar Verma) to resolve the difference of opinion

1. Whether the State Legislature has the competence under List II of the Seventh Schedule or Article 288 to impose the impugned tax

2. Whether the tax is, in pith and substance, a tax on "drawal of water" or a tax on the "generation of electricity"

3. Whether Section 17 of the Act suffers from the vice of excessive delegation by granting unfettered power to the Executive to fix tax rates

4. Whether the State is barred by the doctrine of Promissory Estoppel due to agreements promising tax exemptions to the appellants

The Court applied the doctrine of "Pith and Substance" to determine the true nature of the legislation

It relied on State of West Bengal v. Kesoram Industries Ltd., establishing that taxation is a distinct matter and power to tax cannot be derived from general/non-taxing entries

The Court referred to Article 265, which mandates the "authority of law" for tax collection

Article 246 regarding the distribution of legislative fields

On delegation, it applied the principle that "essential legislative functions," including fixing tax rates without policy guidelines or limits, cannot be abdicated to the Executive

Regarding promissory estoppel, it followed Hero Motocorp Ltd. v. Union of India, holding there is no estoppel against the legislature or the exercise of legislative functions

The Court analyzed the charging sections (Sections 2, 12, and 17) and found that the taxable event was not the mere drawal of water, but specifically drawal "for generation of electricity"

It determined that the measure of tax and the nomenclature were secondary to the "pith and substance," which targeted electricity generation—a field not reserved for State taxation in List II

The Court rejected the State's reliance on Entries 17, 18, 45, 49, and 50 of List II, noting that water does not constitute "land" for taxing purposes under Entry 49, nor "minerals" under Entry 50 in this context

Furthermore, the Court found Section 17 unconstitutional because it allowed the State Government to fix and vary tax rates without any legislative guidelines, upper limits, or parliamentary control, amounting to "naked delegation"

However, on the point of Promissory Estoppel, the Court sided with the State/Chief Justice, noting that executive agreements cannot interdict the sovereign power of a Legislature to enact laws

It held that the State Legislature lacks the competence to levy a tax on electricity generation and that the Act suffers from excessive delegation

The plea of Promissory Estoppel was rejected as it cannot operate against the legislature

Consequently, the Act was struck down as unconstitutional
