State Legislature lacks competence to tax electricity generation by mischaracterizing it as a water tax.

Various hydroelectric power companies (appellants) challenged the constitutional validity of "The Uttarakhand Water Tax on Electricity Generation Act, 2012"

A Coordinate Bench of the Uttarakhand High Court initially dismissed the writ petitions in 2021

On appeal, a Division Bench delivered a split verdict in 2023: the then Chief Justice upheld the Act, while the companion judge struck it down as ultra vires. Consequently, the matter was referred to a third judge (Justice Alok Kumar Verma) to resolve the deadlock

The appellants argued that the State lacked legislative competence to tax electricity generation and that the tax violated prior "Implementation Agreements" where the State promised not to impose such levies

1. Whether the true nature (pith and substance) of the tax under the Act is a tax on the "drawal of water" or a tax on the "generation of electricity"

2. Whether the State Legislature possesses the competence to enact such a tax under Entries 17, 18, 45, 49, or 50 of List II, or under Article 288 of the Constitution

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 without legislative guidelines

4. Whether the State is barred by the doctrine of "Promissory Estoppel" from levying the tax due to contractual exemptions in Implementation Agreements

The Court applied the "Doctrine of Pith and Substance" to determine the true character of the legislation, noting that the nomenclature of a tax is not conclusive

It relied on the principle from State of W.B. v. Kesoram Industries Ltd. that taxation is a distinct matter from general subjects of legislation, and power to tax cannot be derived from a general entry

The Court referred to Union of India v. H.S. Dhillon regarding the requirements of Entry 49 List II (taxes on lands/buildings)

Regarding delegation, it applied the rule that while the Legislature can delegate rate-fixing, it must provide a policy or guidelines; otherwise, it constitutes an "abdication of essential legislative functions"

Finally, it upheld the principle that there is "no estoppel against the law" or against the Legislature in the exercise of its legislative functions

The Court analyzed the charging provisions, specifically Sections 2(f), 2(i), and 12, concluding that the taxable event is not the mere drawal of water but the drawal of water specifically for the generation of electricity

Therefore, in pith and substance, it is a tax on electricity generation

The Court rejected the State's reliance on Entry 49 (Land) and Entry 50 (Mineral Rights), ruling that water consumed for power is neither a "land unit" nor was "mineral" defined universally to include water for taxing purposes in this context

Article 288 was held to be an enabling/exempting provision, not an independent source of legislative power

Regarding Section 17, the Court found it to be "naked delegation" because the Act provided no maximum limits or policy guidelines for the Executive to fix tax rates

Lastly, the Court ruled against the appellants on promissory estoppel, stating that a State Government’s contractual promise cannot bind the State Legislature’s sovereign power to enact a law

The Court also held that Section 17 of the Act is void for excessive delegation

However, it clarified that the plea of promissory estoppel cannot be used to strike down a legislative act. The reference was answered in favor of the appellants, effectively leading to the striking down of the Act.
