Most litigants know the Supreme Court as the end of the appellate road. Article 131 of the Constitution gives it a different character altogether: a court of first instance — the only court — for disputes between States, or between States and the Union. In State of Himachal Pradesh v. Union of India, Original Suit No. 2 of 1996, 2026 INSC 1200, decided on 6 November 2026, a Bench of Chief Justice Surya Kant and Justices Joymalya Bagchi and V. Mohana closed one of the longest-running exercises of that jurisdiction: the quantification and delivery of Himachal Pradesh’s share of power from the Bhakra-Nangal and Beas projects, decreed in principle in 2011 but unresolved in arithmetic for another fifteen years.
Sixty years of unfinished apportionment
The Bhakra-Nangal and Beas projects were built substantially on land of the former princely State of Bilaspur and the Kangra district — territory that is today Himachal Pradesh. When Punjab was reorganised in 1966, Section 78 of the Punjab Reorganisation Act provided for apportioning the projects’ rights and liabilities among the successor States, by agreement or, failing that, by Central Government order. Neither happened; power flowed on an ad hoc basis for decades. Himachal sued under Article 131 in 1996, claiming free power as the home State and a population-based share, after the Central Government rejected its claim in 1994.
The 2011 decree and what it left open
By judgment of 27 September 2011, the Court partly decreed the suit: the claim was within time, constitutional objections failed, and Himachal was held entitled to 7.19 percent of composite Punjab’s share — expressed as fixed percentages of Bhakra-Nangal and of each Beas unit. The 12 percent free-power claim failed for want of any constitutional or legal foundation. Crucially, the Court left the computation of arrears to the Union. That computation became a second round of litigation in itself: the Union arrived at arrears of 13,066 million units for 1966–2011; Himachal accepted the quantum but fought for a higher valuation rate and separately claimed about Rs 1,745 crore spent on open-market power purchases; Punjab sought deductions and a conversion of Himachal’s capital liability at current rates; Haryana disputed the inter se sharing ratios.
Execution, not a second trial
The Court’s organising principle was stated plainly: this stage is in the nature of execution of the 2011 decree, and none of the parties would be permitted to reopen what the decree settled. On that footing it rejected Punjab’s deduction of daily supplies already accounted for in the capital-cost calculus, and its attempt to convert the capital liability at present-day operation and maintenance rates — arrears of an earlier era cannot be priced at today’s tariffs. The Union’s computation, the product of several converging methods rather than a single formula, was accepted as the reasoned baseline. The one concession went the other way: the delivery period was stretched from fifteen to twenty years to ease the burden on the supplying States.
The settlement package
- Arrears: 13,066 million units for 1966–2011, to be supplied by Punjab and Haryana during the lean seasons (October to March), in a 58:42 ratio for Bhakra-Nangal and 60:40 for Beas.
- Set-off: Himachal’s capital-cost liability, fixed at about Rs 420.77 crore (Rs 249.23 crore to Punjab, Rs 171.55 crore to Haryana), is extinguished against energy valued at Rs 3.85 per unit — about 1,093 million units.
- Net delivery: the balance of roughly 11,973 million units flows over twenty lean seasons, approximately 598 million units a year.
- Cashless: the entire settlement is implemented in kind; Himachal bears the Bhakra Beas Management Board charges for each year’s tranche.
- Finality: the suit stands disposed of, with the Court warning that the decree must be implemented without reservation.
Why the judgment matters beyond the hills
Three features give the decision general importance. First, it is a working demonstration of Article 131 as a complete civil jurisdiction — pleadings to decree to execution — and of the Court’s willingness to carry an inter-State decree through to enforceable, scheduled performance rather than leaving it at declarations. Second, the judgment’s method is a lesson in execution discipline that resonates with ordinary decree-holders and judgment-debtors: objections that re-argue the decree are turned away; computation disputes are resolved against the party seeking to revalue history at current prices. Third, the cashless, in-kind settlement — energy against energy, liability set off against entitlement — shows the Court shaping relief to what the parties can actually perform, a pragmatism as useful in commercial execution as in federal disputes. For Himachal Pradesh, a claim rooted in the submergence of its land two generations ago ends not in a cheque but in two decades of winter electricity.
Practice note: The judgment is a reminder that the execution stage is won or lost at the decree stage. A decree that leaves computation to a third party — as the 2011 decree left it to the Union — should spell out the method, the rate and the data source, or the parties will spend years litigating arithmetic. Conversely, a judgment-debtor’s objections in execution must attack the computation on the decree’s own terms; attempts to reopen the underlying liability invite the short answer this judgment gave.
Frequently Asked Questions
What is Article 131 and when does it apply?
Article 131 vests the Supreme Court with exclusive original jurisdiction over disputes between the Government of India and one or more States, or between States, if and in so far as the dispute involves a question of law or fact on which a legal right depends. It is a plenary civil jurisdiction: the proceeding is a suit, with pleadings, issues, evidence and a decree, not a petition.
What had the 2011 decree already decided?
It held Himachal Pradesh entitled to 7.19 percent of composite Punjab's share of power from the projects — translated into specified percentages of Bhakra-Nangal and Beas output — rejected the separate claim to 12 percent free power for want of legal basis, and directed the Union to compute the amounts due. The present judgment repeatedly described its own task as execution of that decree, not its reopening.
How were the arrears finally settled?
Arrears of 13,066 million units for 1966 to 2011 are to be delivered in kind, not cash. Himachal's capital-cost liability of about Rs 420.77 crore is set off against energy valued at Rs 3.85 per unit — roughly 1,093 million units — and the balance of about 11,973 million units is to be supplied by Punjab and Haryana over twenty lean seasons, around 598 million units a year, in fixed ratios for each project.
Why did the Court refuse Punjab's recalculations?
Because they amounted to relitigating the decree. The claimed deduction of daily supplies already figured in the capital-cost computation, and converting a historic liability at today's operation and maintenance rates was found inaccurate — arrears belonging to an earlier period cannot be valued at current rates. Execution proceedings enforce a decree; they are not a second trial of it.
