Triple test, adrift: On the ruling on definition of ‘industry’
A nine-judge Constitution Bench of the Supreme Court, in State of Uttar Pradesh v. Jai Bir Singh (delivered August 20, 2026), ruled by a 5:4 majority that the "triple test" for defining "industry" under the Industrial Disputes Act, 1947, needs refinement, nearly five decades after it was laid down.
The Bench held that the essential framework of the 1978 triple test has stood the test of time, but certain elements and the accompanying guidelines require modification to address concerns about sovereign, welfare and charitable functions being swept into the definition.
The Court clarified that the reformulated test will apply prospectively only — disputes already decided, settled, or pending under the now-repealed Industrial Disputes Act, 1947, will continue to be governed by the original 1978 triple test.
An editorial view held that the Court should not have moved away from a workable, decades-old judicial test, given the uncertainty a mid-course change creates for ongoing labour classification disputes.
The "Triple Test" and Bangalore Water Supply v. A. Rajappa (1978)
The triple test originated in Bangalore Water Supply and Sewerage Board v. A. Rajappa (1978), decided by a seven-judge Bench of the Supreme Court, which gave a deliberately wide reading to the word "industry" under Section 2(j) of the Industrial Disputes Act, 1947.
Key Details
- The test asks whether there is: (i) a systematic activity, (ii) organised by the cooperation between employer and employees, (iii) for the production or distribution of goods/services calculated to satisfy human wants — irrespective of profit motive.
- The only judicially carved-out exception was for sovereign functions of the State (e.g., defence, legislative and primary inherent functions of government).
- The ruling brought a very wide range of establishments — hospitals, educational institutions, charitable bodies, clubs — within the definition of "industry," triggering decades of litigation over its scope.
The 2026 nine-judge Bench was specifically convened to reconsider whether Bangalore Water Supply's broad approach needed narrowing, especially for sovereign-adjacent activities such as defence research, atomic energy and space — the very edge cases the 1978 test struggled to classify cleanly.
Section 2(j), Industrial Disputes Act, 1947 and Constitutional Placement
Section 2(j) of the Industrial Disputes Act, 1947 defines "industry" as any business, trade, undertaking, manufacture, or calling of employers, and includes any calling, service, employment, handicraft, or industrial occupation of workmen. "Trade unions" and "industrial and labour disputes" fall in the Concurrent List of the Constitution, giving both Parliament and State legislatures power to legislate — with Parliamentary law prevailing in case of repugnancy under Article 254.
Key Details
- The Industrial Disputes Act, 1947 came into force on April 1, 1947 and has since been subsumed under the newer labour codes (the Industrial Relations Code, 2020 consolidates it along with the Trade Unions Act, 1926 and the Industrial Employment (Standing Orders) Act, 1946), though the 2026 ruling concerns disputes under the pre-repeal 1947 Act.
- Correct classification as "industry" determines whether workers get access to industrial adjudication machinery (Labour Courts, Industrial Tribunals) and statutory protections against unfair dismissal/lay-off.
The core legal question in Jai Bir Singh was precisely how far Section 2(j)'s definition should stretch to cover State/public bodies performing welfare or regulatory functions — the same question at the heart of the original 1978 case.
Nine-Judge Bench Review and Prospective Overruling
Constitution Benches of five or more judges are convened under Article 145(3) of the Constitution when a case involves a substantial question of law as to interpretation of the Constitution or a earlier large-Bench precedent needs reconsideration. The doctrine of "prospective overruling" — used here — allows a court to change legal interpretation for future cases while shielding past, settled transactions from being reopened.
Key Details
- A larger Bench (nine judges) was needed because the original triple test was laid down by a seven-judge Bench; a smaller Bench cannot overrule a larger Bench's precedent (judicial discipline principle).
- Prospective overruling in Indian constitutional law traces to I.C. Golaknath v. State of Punjab (1967), where the Supreme Court first applied the doctrine to shield past actions from a changed legal position.
The Court's explicit direction that the new, refined test applies only prospectively — leaving pending disputes to be decided under the 1978 triple test — is a textbook application of prospective overruling to prevent retrospective disruption of settled industrial relations.
- Bangalore Water Supply and Sewerage Board v. A. Rajappa: decided February 21, 1978, by a seven-judge Bench, laid down the triple test under Section 2(j) of the Industrial Disputes Act, 1947.
- State of Uttar Pradesh v. Jai Bir Singh, 2026 INSC 897: decided by a nine-judge Constitution Bench on August 20, 2026, by a 5:4 majority, refining (not overturning) the triple test.
- The refined test applies prospectively; pending and past disputes remain governed by the 1978 test.
- "Trade unions; industrial and labour disputes" fall under the Concurrent List of the Seventh Schedule to the Constitution.
- Constitution Benches under Article 145(3) require a minimum of five judges; here, the Bench size (nine) matched or exceeded the size of the precedent Bench (seven) being reconsidered.
