Critically analyse the 'triple test' laid down in Bangalore Water Supply and Sewerage Board v. R. Rajappa (1978) and its relevance to contemporary labour law.

Section 2(j) of the Industrial Disputes Act, 1947 defined "industry" without a litigation-proof test [1], leaving courts to fill the gap. In 1978, a seven-judge Bench in Bangalore Water Supply laid down the triple test, a worker-protective standard whose continued relevance is now contested after labour-law codification [2].

What the triple test held

• Any systematic, organised activity, involving employer-employee cooperation, for production or supply of goods and services to consumers, qualifies as an industry [2].
• Authored by Justice V.R. Krishna Iyer, it deliberately read Section 2(j) expansively, treating dominant-nature rather than profit motive as decisive [2].

Merits

• Widened the safety net: hospitals, educational institutions, municipalities and charitable bodies were brought within conciliation, adjudication and strike-related protections [2].
• Gave nearly five decades of settled interpretive certainty to tribunals and labour departments [2].
• Advanced the Directive Principles' vision of just and humane conditions of work by resisting narrow, employer-friendly readings.

Criticisms

• Over-extended labour regulation into non-commercial, charitable and quasi-sovereign functions, raising compliance costs for welfare institutions [2].
• Its breadth blurred the line between sovereign functions and commercial activity, generating persistent litigation rather than closing it.
• It substituted judicial legislation for a definitional task properly belonging to Parliament.

Contemporary relevance

• The Industrial Relations Code, 2020 (Act No. 35 of 2020) subsumed the IDA 1947, the Trade Unions Act 1926 and the Standing Orders Act 1946, and was brought into force in November 2025 [3].
• A nine-judge Constitution Bench has since held that "industry" under the IRC must be read from the Code's own text and context, not by automatic transplantation of the 1978 test — while a strong minority defended that precedent as essential to industrial peace [2].

The triple test remains a landmark in worker-protective statutory interpretation, though its judicially-crafted breadth was always vulnerable to legislative revision. Its true legacy lies not in the formula but in its purposive spirit; as fresh IRC jurisprudence develops, courts and Parliament should ensure that codification simplifies compliance without narrowing the constitutional promise of dignified work.
