State Legislature Lacks Competence to Levy Water Tax on Electricity Generation as it is Pith and Substance a Tax on Electricity.

Various hydroelectric power corporations challenged the constitutional validity of "The Uttarakhand Water Tax on Electricity Generation Act, 2012," which imposed a tax on water drawn for power generation.

The appellants argued that despite the nomenclature, the tax was effectively on the generation of electricity, a subject outside the State’s legislative competence.

They further contended that the State was barred by the doctrine of promissory estoppel due to prior Implementation Agreements exempting them from such taxes.

A Division Bench of the High Court delivered a split verdict on 25.10.2023, leading to this reference under Chapter VIII Rule 3 of the High Court Rules.

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

2. Whether Section 17 of the Act suffers from the vice of excessive delegation by granting unfettered power to the Executive to fix tax rates without guidelines.

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

4. Whether the State is barred from levying the tax by the doctrine of promissory estoppel.

The Court applied the Doctrine of Pith and Substance to determine the true nature of the legislation.

It relied on Article 246 and the Seventh Schedule, noting the distinction between general legislative entries and taxing entries as established in State of W.B. v. Kesoram Industries Ltd.

The Court followed the principle that "authority of law" under Article 265 requires strict legislative competence.

Regarding delegation, it applied the rule from Union of India v. M/s Mohit Minerals Pvt. Ltd., stating that essential legislative functions, such as fixing tax rates without guidelines or limits, cannot be delegated.

It upheld the principle that there is no promissory estoppel against the exercise of legislative functions, citing M/s Hero Motocorp Ltd. v. Union of India.

The Court examined the charging provisions (Sections 2, 12, and 17) and concluded that the taxable event was not the mere drawal of water, but specifically the drawal for electricity generation; thus, in pith and substance, it was a tax on electricity generation.

The Court rejected the State’s reliance on Entry 49 (Taxes on lands) and Entry 50 (Taxes on mineral rights) of List II, holding that water used for non-consumptive electricity generation does not constitute "land" or "minerals" in a taxing sense.

On Article 288, the Court held it is an enabling/exemption provision and not an independent source of legislative competence.

Regarding Section 17, the Court found "excessive delegation" because the Act provided no maximum limits or policy guidelines for the Executive to fix tax rates, amounting to an abdication of essential legislative functions.

The Court sided with the State on promissory estoppel, reasoning that a government’s contractual promise cannot interdict the Sovereign power of a Legislature to enact laws.

Section 17 was held void due to excessive delegation and the Act was struck down in its entirety.

The plea of promissory estoppel was rejected as inapplicable against the Legislature.
