Examine how the codification of labour laws since 2019-20 has altered the scope of judicial precedent in labour jurisprudence.

Between 2019 and 2020 Parliament consolidated 29 central labour laws into four Codes, of which the Industrial Relations Code, 2020 (Act No. 35 of 2020) subsumed the Industrial Disputes Act 1947, the Trade Unions Act 1926 and the Standing Orders Act 1946 [2]. By replacing the statutory text on which decades of case law rested, codification has narrowed the automatic reach of precedent, without displacing it entirely.

Re-legislation resets the interpretive base

• "Industry" was defined in Section 2(j) of the IDA, 1947; the Bangalore Water Supply v. R. Rajappa (1978) seven-judge Bench built the "triple test" on that text, sweeping in hospitals, schools and municipalities [1].
• With the IDA repealed on the IRC's enforcement (21 November 2025), a nine-judge Constitution Bench held that the 1978 test does not automatically transplant onto the IRC; courts must read "industry" from the Code's own text and context [1].

Precedent survives, but as persuasive scaffolding

• The ruling limits rather than overrules: the 6:3 split, with Justices Nagarathna, Datta and Bhuyan calling the exercise "unwarranted", shows judicial caution about disturbing settled doctrine [1].
• Bench hierarchy remains the operative mechanism — only a larger Bench could revisit the 1978 holding [1].

Consequences for the field

• Administrative: tribunals and labour departments face interpretive uncertainty and fresh litigation while IRC-specific case law is built [1].
• Social: workers in health and education risk losing settled access to conciliation, adjudication and strike protections if reclassified; Justice Nagarathna's warning on industrial peace captures this [1].
• Economic: employers gain clarity on dispute exposure, aiding the ease-of-doing-business rationale behind consolidation [2].

Codification has thus shifted labour jurisprudence from precedent-led continuity to text-led fresh construction. Early authoritative guidance from the Court, coupled with clear rules under the IRC, can convert this transitional uncertainty into a coherent framework that balances employer flexibility with workers' constitutional right to a dignified livelihood.
