NHPC Ltd. Vs State of Himachal Pradesh Secretary & Ors. (Supreme Court of India)
Summary: The Supreme Court of India, in NHPC Ltd. Vs State of Himachal Pradesh Secretary & Ors., 2023 INSC 810, together with connected appeals filed by authorities of the Bhakra Beas Management Board, examined the constitutional validity of the Himachal Pradesh Passengers and Goods Taxation Act, 1955, as amended by the Himachal Pradesh Passengers and Goods (Amendment and Validation) Act, 1997. The principal question was whether passenger tax could be imposed upon public-sector organisations providing free transport facilities to their employees and the children of employees. NHPC and the other appellants operated buses for transporting employees between residential colonies and remote project sites and for carrying their children to schools. Although no fares were collected and the facilities were provided as welfare measures, the State tax authorities sought to levy passenger tax under the legislation. The appellants challenged the assessments and the validity of the statutory framework.
The controversy arose from an earlier Himachal Pradesh High Court judgment dated 27 March 1997, which had held that the original legislation did not effectively cover the appellants’ transport activities. The High Court identified deficiencies in the charging provisions, particularly the absence of clear statutory definitions of “route” and “normal rate”, and directed the refund of passenger tax collected. Following dismissal of the State’s special leave petition, the legislature enacted the 1997 Amendment and Validation Act with retrospective effect. The amendments enlarged the definitions of business and motor vehicles, introduced definitions of road and private service vehicle, and replaced the defective charging mechanism with Section 3(1A). The appellants argued that these amendments failed to cure the original defects, imposed an excessive retrospective burden and exceeded the legislative competence of the State under Article 246 read with Entry 56 of List II of the Seventh Schedule of the Constitution.
The Supreme Court examined the constitutional principles governing retrospective and validating legislation. Referring to precedents including Shri Prithvi Cotton Mills Ltd. Vs Broach Borough Municipality, Indian Aluminium Co. Vs State of Kerala, State of Tamil Nadu Vs Arooran Sugars Ltd., Bakhtawar Trust Vs M.D. Narayan and Madras Bar Association Vs Union of India, the Court explained that a legislature cannot directly overrule a judicial decision merely by declaring it ineffective. However, a competent legislature can retrospectively amend a statute to remove the legal defects forming the foundation of an earlier judgment. The Court found that the 1997 amendments had effectively cured the deficiencies identified by the High Court. By defining the relevant expressions and introducing a statutory method for determining fares where transport was provided without consideration, the legislature had validly brought non-fare-paying passengers within the charging provisions.
On the question of legislative competence, the Supreme Court held that the legislation imposed tax on passengers and goods carried by road in motor vehicles and not a tax on the vehicles themselves. Consequently, the levy fell within Entry 56 of List II of the Seventh Schedule, and the Himachal Pradesh Legislature possessed the requisite constitutional authority. The Court rejected the contention that passenger tax could arise only when an operator actually collected fare from passengers. It also rejected the argument that free transportation incidental to the appellants’ principal activities was beyond the statutory definition of business. The Court accordingly upheld the constitutional validity of the 1955 Act as amended by the 1997 Amendment and Validation Act, and concluded that transporting employees and their children free of charge constituted a taxable activity under Section 3(1A).
Nevertheless, the Supreme Court granted substantial relief regarding the period for which tax could be recovered. The Court recognised that the appellants were public-sector organisations operating hydroelectric and irrigation projects in difficult hilly areas, rather than commercial passenger transport operators. It also considered the approximately twenty-six years that had elapsed since the validating legislation and the prolonged uncertainty surrounding the assessments. Exercising its extraordinary powers under Article 142 of the Constitution, the Supreme Court directed that the appellants would be liable to pay passenger tax only with effect from 1 April 2023 and not for any earlier period. Thus, although the appeals were dismissed and the Himachal Pradesh High Court judgments were affirmed, the appellants obtained protection against retrospective recovery of passenger tax for periods preceding 1 April 2023. The parties were directed to bear their respective costs.
