The three-part test from Bangalore Water Supply (1978) for deciding whether an activity is an 'industry' under the Industrial Disputes Act, 1947.
The triple test is the judicial standard for deciding whether an establishment is an 'industry' within Section 2(j) of the Industrial Disputes Act, 1947 — the threshold question in labour litigation, because the Act's protections on dismissal, retrenchment, lay-off and dispute adjudication apply only to an industry. It was laid down by a seven-judge bench of the Supreme Court in Bangalore Water Supply and Sewerage Board v. A. Rajappa (1978), which held that an activity is an industry if it is (1) a systematic activity, (2) organised through cooperation between employer and employee, and (3) directed at the production or distribution of goods or services calculated to satisfy human wants and wishes. The reach of the test is deliberately wide: hospitals, universities, research institutes, charitable bodies, clubs and even professional firms can qualify, provided an organised employer-employee relationship exists. On 20 August 2026 a nine-judge bench in State of Uttar Pradesh v. Jai Bir Singh (2026 INSC 897) settled a reference that had been pending since 2005 and held that the triple test continues to govern every dispute still pending under the now-repealed Industrial Disputes Act.
Type: ConceptThree cumulative limbs — systematic activity; cooperation between employer and employee; production or distribution of goods or services to satisfy human wants. All three must be present
Profit motive is irrelevant. A charitable or loss-making body can still be an industry, which is why the test swept in hospitals and educational institutions
Sovereign functions are excluded — but only the narrow, inalienable core of statehood such as defence, legislation, the administration of justice and law and order. Welfare and service activities of the State are not exempt merely because the State runs them
Where an undertaking has both exempt and non-exempt parts, the dominant nature of the activity decides its character
Laid down by a seven-judge bench in Bangalore Water Supply and Sewerage Board v. A. Rajappa (1978), authored principally by Justice V. R. Krishna Iyer
The definition it interprets — Section 2(j) of the Industrial Disputes Act, 1947 — is the gateway to the whole Act: no industry, no industrial dispute, no tribunal jurisdiction
A 2005 reference in State of Uttar Pradesh v. Jai Bir Singh, arising out of whether a state forest department's social forestry scheme was an industry, questioned the 1978 test and referred it to a larger bench, where it remained pending for over two decades
The nine-judge bench decided it on 20 August 2026 (2026 INSC 897), unanimously holding that the triple test governs all disputes still pending under the repealed 1947 Act, though individual judges differed on whether the 1978 formulation was correct in principle. Several separate opinions were delivered
The Court expressly left the new law free: 'industry' under Section 2(p) of the Industrial Relations Code, 2020 — in force from 21 November 2025 — must be construed on its own text and scheme, uncoloured by Bangalore Water Supply or by any reformulation debated in the 2026 judgment
Frequency: Moderate in UPSC Prelims and high in judiciary and law-optional papers; the 2026 nine-judge ruling makes it a likely current-affairs-plus-static question in the next cycle
A tribunal faced with a claim under the Industrial Disputes Act must first ask whether the establishment is an industry at all, and it does so by working through the limbs in order.
Step 1 — Is the activity systematic, that is, organised and continuous rather than casual or one-off?
Step 2 — Is it carried on through cooperation between an employer and employees? A solitary practitioner with no employees fails here
Step 3 — Does it produce or distribute goods or services that satisfy human wants and wishes? Profit motive and the nature of ownership are irrelevant at this stage
Step 4 — Is the activity a sovereign function in the strict sense — legislation, justice, defence, law and order? If so, it falls outside the Act; welfare and service functions of the State do not
Step 5 — Where an undertaking mixes exempt and non-exempt work, apply the dominant nature test and classify it by its predominant activity
Section 2(j) of the 1947 Act defined industry in broad but circular terms, and for three decades the Supreme Court moved back and forth over whether hospitals, universities, government departments and charities were covered. Bangalore Water Supply settled that in 1978 with a deliberately expansive test, and the expansion itself became the grievance: states and institutions argued that treating welfare schemes and charitable bodies as industry burdened them with industrial adjudication. That argument produced the 2005 reference in Jai Bir Singh, which then waited twenty-one years while Parliament replaced the statute altogether.
Industrial Disputes Act enacted; Section 2(j) defines 'industry'
Bangalore Water Supply and Sewerage Board v. A. Rajappa — a seven-judge bench lays down the triple test
In State of Uttar Pradesh v. Jai Bir Singh, arising from a social forestry scheme, a bench doubts the 1978 test and refers it to a larger bench
Parliament enacts the Industrial Relations Code, 2020, subsuming the Industrial Disputes Act and defining 'industry' afresh in Section 2(p)
The Industrial Relations Code, 2020 comes into force, repealing the Industrial Disputes Act, 1947
A nine-judge bench decides Jai Bir Singh (2026 INSC 897): the triple test governs all pending disputes under the repealed Act, while the Code's definition must be read independently
Whether an establishment is an 'industry' decides whether its workers can invoke statutory protection against dismissal and retrenchment and take a dispute to a labour court at all, so the definition is the single most consequential line in Indian industrial law. The 1978 test extended that protection to sectors that had argued they were outside commerce — hospitals, schools, research bodies, charities and government service undertakings — and the 2026 judgment preserves it for the large body of litigation still working through tribunals under the old Act, which matters practically because such cases can run for decades. The forward-looking half of the judgment is the more interesting one: by refusing to carry Bangalore Water Supply into Section 2(p) of the Industrial Relations Code, the Court left the scope of the new definition genuinely open, which means the boundary between welfare activity and industry will be litigated again from the beginning. For a Mains answer on labour codes or on judicial management of transitional law, that deliberate two-track outcome is the point worth making.

2026: State of Uttar Pradesh v. Jai Bir Singh, 2026 INSC 897, nine-judge bench, 20 August 2026, deciding a 2005 reference
Held: the triple test governs all disputes still pending under the repealed 1947 Act
Held: 'industry' under Section 2(p) of the Industrial Relations Code, 2020 must be read independently. The Code took effect on 21 November 2025
Systematic activity; activity organised through cooperation between employer and employee; and the production or distribution of goods or services calculated to satisfy human wants and wishes. All three must be satisfied for an establishment to be an 'industry'.
Bangalore Water Supply and Sewerage Board v. A. Rajappa (1978), decided by a seven-judge bench of the Supreme Court, interpreting Section 2(j) of the Industrial Disputes Act, 1947.
Yes. Profit motive is not a requirement under the triple test, which is why hospitals, universities, research institutes, charitable bodies and systematically run clubs can qualify, provided an organised employer-employee relationship exists.
In State of Uttar Pradesh v. Jai Bir Singh (2026 INSC 897), decided on 20 August 2026, a nine-judge bench held that the Bangalore Water Supply triple test continues to govern all disputes still pending under the repealed Industrial Disputes Act, 1947. It did not overrule the test.
No. The 2026 bench held that 'industry' under Section 2(p) of the Code must be interpreted entirely on the Code's own text and scheme, without being anchored to Bangalore Water Supply or to any reformulation discussed in that judgment. The Code came into force on 21 November 2025.
