State Legislature lacks competence to tax electricity generation; unfettered rate-fixing power constitutes excessive delegation.

The State of Uttarakhand enacted "The Uttarakhand Water Tax on Electricity Generation Act, 2012," which levied a tax on "users" drawing water for the purpose of generating electricity

Various power corporations 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, while Justice Ravindra Maithani struck it down as ultra vires. Consequently, the matter was referred to Justice Alok Kumar Verma for a tie-breaking opinion

1. Whether the State Legislature has the legislative competence to impose a tax on drawing water specifically for electricity generation under Entries 17, 45, 49, or 50 of List II or Article 288 of the Constitution

2. Whether the Act, specifically Section 17, is void due to the "excessive delegation" of power to the Executive to fix tax rates without legislative guidelines

3. Whether the State is barred by the doctrine of "Promissory Estoppel" from levying the tax due to prior Implementation Agreements promising no such levies

The Court applied the "Doctrine of Pith and Substance" to determine the true character of the levy

It relied on the principle that "Taxation" is a distinct matter from general subjects of legislation, and the power to tax cannot be derived from a general entry as an ancillary power (State of West Bengal v. Kesoram Industries Ltd.)

The Court referred to Article 265, which mandates that taxes must be levied by the "authority of law", and the principle from Union of India v. H.S. Dhillon that Entry 49 List II (taxes on lands) requires taxing land and buildings as separate units

Regarding delegation, it applied the rule that the legislature cannot delegate "essential legislative functions" like fixing tax rates without providing guidelines

Finally, it upheld that there is no "Promissory Estoppel" against the exercise of legislative functions (M/s Hero Motocorp Ltd. v. Union of India)

The Court analyzed the "charging section" (Section 17) and definitions (Section 2), concluding that the taxable event was not the mere drawal of water, but specifically the drawal for electricity generation

In "pith and substance," this constituted a tax on the generation of electricity, a field not available to the State under List II of the Seventh Schedule

The Court rejected the State’s argument that water is "land" (Entry 49) or a "mineral" (Entry 50) for the purpose of this specific taxing power, noting that taxation must be traced to a specific taxing entry, not inferred from general entries like Entry 17

Furthermore, the Court found that Section 17 granted "naked delegation" of power to the Executive to fix and vary rates without any ceiling or policy guidelines, rendering it unconstitutional

Regarding promissory estoppel, the Court held that while the State Government made promises in agreements, it cannot bind the State Legislature's sovereign power to enact laws

It held that the State lacks legislative competence to tax electricity generation and that Section 17 suffers from excessive delegation. However, it rejected the appellants' plea of Promissory Estoppel, ruling that the doctrine cannot interdict the exercise of legislative functions
