State Legislature lacks legislative competence to impose tax on electricity generation under the guise of water tax.

In brief

The question

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

The court held

The Court answered the reference by concurring with Justice Ravindra Maithani, holding that "The Uttarakhand Water Tax on Electricity Generation Act, 2012" is ultra vires the Constitution because the State Legislature lacks the competence to tax electricity generation.

It also directed

The Court further held that Section 17 is void due to excessive delegation.

However, it held that the plea of promissory estoppel cannot be maintained against the legislature.

01Facts

Several hydroelectric power companies (appellants) challenged the constitutional validity of the Uttarakhand Water Tax on Electricity Generation Act, 2012, which imposed a tax on water drawn for power generation.

¶ 1

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

¶ 2

The matter was referred to a third judge, Hon’ble Alok Kumar Verma, J., for a majority opinion.

¶ 2

The appellants contended that the State lacked legislative competence to tax electricity generation and that the Act violated the doctrine of promissory estoppel, as the State had previously signed agreements promising no such taxes or levies would be imposed.

02Issues

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

¶ 30

ii.2. Whether the State Legislature has the competence under List II of the Seventh Schedule or Article 288 of the Constitution to enact the law

¶ 51

iii.3. Whether Section 17 of the Act suffers from excessive delegation of legislative power

¶ 43

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

¶ 67

03Law Applied

The Court applied the "Doctrine of Pith and Substance" to determine the true character of the legislation regardless of its nomenclature.

¶ 33

It relied on the principle that taxation is a distinct matter from general subjects of legislation, and power to tax cannot be derived from a general entry; specifically, Entry 17 (Water), Entry 18 (Land), and Entry 45 (Land Revenue) of List II do not authorize a tax on electricity.

¶ 64-65

The Court cited State of West Bengal v. Kesoram Industries Ltd. to emphasize that taxing power must be express.

¶ 65

Regarding delegation, it applied the rule that fixing tax rates without legislative guidelines or limits constitutes "excessive delegation".

¶ 45

Finally, it applied the principle from M/s Hero Motocorp Ltd. v. Union of India that there is no promissory estoppel against the legislature in the exercise of its legislative functions.

Uttarakhand water tax and electricity Generation Act 20 provisions

Section 1 Section 2 Section 3 Section 4 Section 5 Section 6 Section 7 Section 8 Section 9 Section 10 Section 11 Section 12 Section 13 Section 14 Section 15 Section 16 Section 17 Section 18 Section 19 Section 21

04Reasoning

The Court analyzed the charging section and definitions, noting that tax under the Act is only triggered when water is drawn specifically "for generation of electricity," making the generation the taxable event rather than mere drawal of water.

¶ 39

It rejected the State's reliance on Entry 49 (Taxes on lands) and Entry 50 (Mineral rights), finding that water used for non-consumptive power generation does not constitute "land" or "minerals" in this constitutional context.

¶ 58-61

The Court found that Article 288 is an enabling/saving provision and not an independent source of legislative competence.

¶ 63

Regarding Section 17, the Court observed that the legislature abdicated its essential function by granting the government unfettered power to fix rates without any policy guidelines or upper/lower limits, rendering it a "naked delegation".

¶ 45

However, on the point of promissory estoppel, the Court held that despite contractual promises, the State’s legislative power cannot be interdicted by prior executive agreements.
