Legislative Competence to Levy Water Tax on Electricity Generation and the Doctrine of Excessive Delegation

The State of Uttarakhand enacted "The Uttarakhand Water Tax on Electricity Generation Act, 2012," which levied a tax on "users" (hydroelectric power companies) for drawing water from any source within the state for electricity generation.

Several power companies challenged the Act’s constitutional validity, arguing it was a colorable exercise of power to tax electricity generation—a field they claimed the State lacked competence in—and that it violated contractual "Implementation Agreements" that promised tax exemptions.

A Division Bench of the Uttarakhand High Court delivered a split verdict on 25.10.2023: the Chief Justice upheld the Act, while Justice Maithani struck it down as ultra vires.

The matter was subsequently referred to Justice Alok Kumar Verma for a tie-breaking opinion.

1. Whether the State Legislature has the competence to enact a law imposing a tax on the drawal of water specifically for electricity generation under Entries 17, 18, 45, 49, or 50 of List II or Article 288 of the Constitution.

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

3. Whether Section 17 of the Act suffers from the vice of excessive delegation by allowing the Government to fix tax rates without legislative guidelines.

4. Whether the State is barred by the doctrine of promissory estoppel from levying the tax due to prior implementation agreements.

The court applied the "Doctrine of Pith and Substance" to determine the true nature of the levy, distinguishing it from the "measure of tax".

Taxation is a distinct matter and cannot be inferred from general legislative entries (State of West Bengal v. Kesoram Industries Ltd.).

Water used for electricity is not "land" or "mineral" for the purpose of taxing entries under Entry 49 (Taxes on lands and buildings) and Entry 50 (Taxes on mineral rights) of List II (Union of India v. H.S. Dhillon).

Fixing tax rates without a ceiling or guideline constitutes an abdication of "essential legislative functions".

There is no "promissory estoppel" against the legislature exercising its sovereign legislative functions (M/s Hero Motocorp Ltd. v. Union of India).

The court analyzed the statutory definitions, specifically Section 2(f) and 2(i), and concluded that the taxable event was not the mere drawal of water, but the drawal of water specifically for electricity generation.

In pith and substance, the tax was on the generation of electricity, a field not available to the State under List II.

The court rejected the State's argument that water is "land" (Entry 49) or a "mineral" (Entry 50), clarifying that the cited precedents (Rekhchand Mohota and Ichchapur Industrial) were limited to their specific statutory contexts and did not grant a general power to tax water usage under those entries.

Regarding Section 17, the court found "naked delegation" because the Act provided no maximum limits or policy guidelines for the executive to fix tax rates.

The court disagreed with the appellants on promissory estoppel, reasoning that a State Government’s contractual promise cannot bind the State Legislature’s sovereign power to enact tax laws.

Section 17 of the Act is bad for excessive delegation.

The plea of promissory estoppel is not maintainable against a legislative act.

The final opinion is that the Act is unconstitutional and void.
