The Himachal Pradesh High Court has upheld the State’s power to levy electricity duty but has imposed strict, numerically-based limits on rate revisions, directing the government to adopt a clear schedule for future enhancements and to adjust any excess duty already collected from stone-crusher units.
Background & Facts
The Dispute
The petitioners are a group of industrial units engaged in stone-crushing, mining and related activities, each registered with the Industries Department and holding mining leases for extraction of stone, boulder, bajri and sand. They contend that the State Government, under the Himachal Pradesh Electricity (Duty) Act, 2009 (the “Act”), has unlawfully increased the electricity duty levied on them.
Key Facts
- 20.07.2017 - HP State Electricity Board (HPSEBL) issued a communication (Annexure P-3) fixing the electricity duty for stone-crushers at 11 %.
- 01.09.2023 - Department of MPP & Power issued Notification P-4 under Section 11(2) of the Act, raising the duty for stone-crushers to 25 % (a 14 % absolute increase).
- 18.01.2024 - A second Notification P-5 further raised the duty for stone-crushers to 37.50 %.
- 18.09.2024 - Notifications P-7 and P-8 reduced the duty for other large industrial consumers (from 19 % to 16.5 % and 19 % to 10 %) but expressly excluded stone-crushers, leaving them on the higher rate.
- The Act’s Section 3 enumerates duty rates for various consumer categories; Section 11(2) permits the State to revise rates “not exceeding 50 % at any one time” of the rate specified in Section 3.
- Petitioners argue that the cumulative increase from 11 % to 37.5 % within five months amounts to a 240 % rise, far exceeding the statutory ceiling.
- They also assert that the State lacks authority to create a separate sub-category for stone-crushers, a power that, they claim, resides with the Himachal Pradesh Electricity Regulatory Commission (HPERC) under Clause 2.3 of the HP Electricity Supply Code, 2009.

Parties' Positions
- Petitioners (stone-crusher units) argue that the State has exceeded the 50 % ceiling, that the power to sub-categorise is absent, and that the provisions are vague, arbitrary and violative of Article 14.
- Respondents (State of Himachal Pradesh and HPSEBL) contend that the power to revise rates is a valid legislative competence, that the classification serves a rational nexus with higher consumption and environmental impact, and that the increase is within the State’s fiscal prerogative.
Relief Sought
Petitioners seek:
- Quashing of Notifications P-4 and P-5.
- Inclusion of stone-crushers in the reduced-rate category applicable to other large industrial consumers.
- Refund or adjustment of excess duty already paid.
- A declaration that Section 11(2) is unconstitutional or, alternatively, that it be read down to limit the State’s power.
The Legal Issue
- Does Section 11(2) of the Himachal Pradesh Electricity (Duty) Act, 2009 empower the State to increase electricity-duty rates by more than 50 % of the existing rate at a time?
- Can the State, under the same provision, create a separate sub-category for stone-crushers, thereby deviating from the classification scheme prescribed in Clause 2.3 of the Himachal Pradesh Electricity Supply Code, 2009?
- If the provision is vague, should the court strike it down or employ the doctrine of “reading down” to preserve its constitutionality?
Arguments Presented
For the Petitioners
- The statutory ceiling of “not exceeding 50 % at any one time” is a hard limit; the jump from 11 % to 25 % (a 14 % absolute increase, i.e., 127 % of the base) and subsequently to 37.5 % (a 240 % rise) breaches this limit.
- Section 11(2) lacks any temporal guidance; without a minimum interval, the State can arbitrarily stack revisions, violating the principle of reasonableness under Article 14.
- Classification of consumers is vested in HPERC; the State’s unilateral sub-categorisation of stone-crushers exceeds its delegated authority.
- The provision is vague and unbridled, rendering it susceptible to being struck down as unconstitutional.
For the Respondents
- Section 11(2) confers a broad fiscal power to the State; the 50 % ceiling is a maximum, not a prohibition on cumulative increases, provided each individual revision does not exceed 50 % of the rate at that moment.
- The State’s classification is based on intelligible differentia - stone-crushers consume disproportionately high electricity and have greater environmental impact, justifying a higher duty.
- The power to levy duty is a taxation power under Entry 53 of List II of the Seventh Schedule; the State’s action is within its legislative competence.
- The doctrine of “reading down” should be applied only if the plain meaning leads to unconstitutionality; here, the provision can be saved by a purposive construction.
The Court's Analysis
The Court began by applying the literal rule of interpretation (B. Premanand v. Mohan Koikal, 2011 4 SCC 266) and held that the words of Section 11(2) must be given their ordinary meaning. It observed that “not exceeding 50 % at any one time” imposes a per-revision ceiling, not a cumulative cap, but the absence of a prescribed interval renders the power vague and prone to abuse.
"The power conferred by Section 11(2) is not a licence to increase rates at will; it must be exercised within a framework that prevents arbitrary escalation and ensures certainty for the affected class of consumers," the Court noted.
The Court then examined the constitutional limitation under Article 14, citing Kartar Singh v. State of Punjab (1994 3 SCC 569) that vague statutes that grant unfettered discretion are liable to be struck down. However, rather than invalidating the provision, the Court employed the doctrine of reading down (Authorized Officer, Central Bank of India v. Shanmugavelu, 2024 6 SCC 641) to narrow the statutory scope, preserving its constitutionality while imposing safeguards.
Regarding the sub-categorisation, the Court distinguished the classification power of HPERC (under Clause 2.3 of the Electricity Supply Code) from the State’s power to levy duty (under Section 3). It held that the two regimes serve different purposes - tariff determination versus tax collection - and therefore the State may re-classify for duty purposes, provided it is based on intelligible differentia and reasonable nexus. The Court rejected the petitioners’ argument that the State’s action was ultra vires, referencing State of Madhya Pradesh v. Ajay Singh (1993 1 SCC 302) on the limits of delegated authority.
Nevertheless, the Court found the absence of guiding principles in Section 11(2) to be a defect. To cure this, it issued a detailed schedule prescribing the maximum permissible enhancement for each year following a revision, thereby giving the provision the required certainty.
The Court also addressed the excess duty already collected, applying the principle that a tax cannot be levied beyond statutory authority (Bimal Chandra Banerjee v. State of Madhya Pradesh, 1970 2 SCC 467). It ordered that any duty paid above the rates specified in the newly-issued schedule be adjusted against future liabilities or refunded within one year.
The Verdict
The High Court did not strike down Section 11(2) of the Himachal Pradesh Electricity (Duty) Act, 2009. Instead, it read down the provision and directed the State to exercise its power of rate enhancement as follows:
- A maximum yearly enhancement of 5 % of the base rate for the first year, 10 % for the second year, increasing incrementally up to a ceiling of 50 % after ten years (see Schedule A in the judgment).
- The applicable duty for stone-crushers shall be 16.05 % from 01.09.2023 and 24.75 % from 18.01.2024, superseding the earlier notifications.
- Any excess duty collected above these rates must be adjusted against future dues or refunded within one year of the order.
- The State is directed to frame or amend rules providing clear intervals and percentages for future revisions, in line with the schedule.
- All pending applications related to the matter are disposed of in accordance with these directions.
What This Means For Similar Cases
Statutory Power Must Be Guided by Clear Principles
- Legislatures should embed specific intervals and percentage caps when delegating fiscal powers to avoid vagueness.
- Courts will prefer reading down over striking down, provided the narrowed construction restores constitutional validity.
Sub-categorisation Requires a Rational Basis
- While the State may create new consumer classes for tax purposes, the classification must be based on intelligible differentia such as consumption volume or environmental impact.
- The authority that fixes tariffs (HPERC) is distinct from the authority that levies duty; overlap does not automatically render the State’s action ultra vires.
Practical Steps for Practitioners
- When challenging a tax-rate revision, quantify the percentage increase and compare it with the statutory ceiling.
- Cite the reading-down doctrine to argue for a narrowed interpretation rather than outright invalidity.
- Prepare detailed calculations of excess duty to support claims for adjustment or refund.
Arguments Presented
For the Petitioners
- The increase from 11 % to 25 % and then to 37.5 % exceeds the 50 % ceiling of Section 11(2).
- Lack of a minimum interval makes the power arbitrary, violating Article 14.
- Stone-crushers classification is a function of HPERC, not the State.
- The provision is vague and should be struck down.
For the Respondents
- Each individual revision stayed within the 50 % limit; cumulative increase is permissible.
- Stone-crushers have higher consumption; differential rates are justified.
- The State’s taxation power under Entry 53 List II is constitutionally sound.
- Reading down can preserve the provision without striking it down.
The Court's Analysis
The Court applied the literal rule, examined constitutional limits, and employed the reading-down doctrine to narrow Section 11(2). It distinguished tariff classification from duty classification and provided a schedule to cure the statutory vagueness.
"The power conferred by Section 11(2) is not a licence to increase rates at will; it must be exercised within a framework that prevents arbitrary escalation and ensures certainty for the affected class of consumers."
The Verdict
The Court upheld the State’s power but read down Section 11(2) and directed a specific enhancement schedule: 5 % in year 1, 10 % in year 2, up to 50 % after ten years. The duty for stone-crushers is fixed at 16.05 % (effective 01.09.2023) and 24.75 % (effective 18.01.2024). Excess duty must be adjusted or refunded within one year. The State must frame rules providing clear intervals and percentages for future revisions.
