Labour Codes in 2026: Which Supreme Court Employment Judgments Still Apply?

Yes, many landmark Supreme Court employment judgments still matter after the new Labour Codes—but not every old judgment can be applied mechanically.

The four Labour Codes were brought into effect from 21 November 2025. In 2026, the correct approach is to ask whether an older judgment lays down a constitutional or general legal principle, interprets language substantially retained in the new Codes, or instead interprets a provision that Parliament has now materially changed.

This distinction has already been reinforced by the Supreme Court itself in State of U.P. v. Jai Bir Singh, 2026 INSC 897, decided on 20 August 2026.

What actually changed under the Labour Codes?

India's new labour-law framework consists of the Code on Wages, 2019, Industrial Relations Code, 2020, Code on Social Security, 2020, and Occupational Safety, Health and Working Conditions Code, 2020. Together, they rationalise a large part of the earlier central labour-law framework.

For employment disputes involving termination, standing orders, retrenchment, trade unions and industrial disputes, the most important statute is the Industrial Relations Code, 2020 (“IR Code”). Its provisions came into force on 21 November 2025.

There was also an important transition during 2026. The Industrial Relations Code (Amendment) Act, 2026, which received Presidential assent on 16 February 2026 and is deemed effective from 21 November 2025, preserved continuity of the existing statutory authorities until the corresponding authorities under the new Code became functional.

The Industrial Relations (Central) Rules, 2026 were subsequently notified on 8 May 2026. These are Central Rules, so an employer must still check which Government is the “appropriate Government” and whether applicable State rules or notifications also govern the establishment.

Does an old Supreme Court labour judgment automatically become invalid when the old Act is repealed?

No. A judicial precedent is not automatically erased simply because the statute it interpreted has been replaced.

What changes is the statutory foundation on which that judgment operated.

If the new Code uses materially similar language, the reasoning of an earlier Supreme Court judgment may remain highly relevant. If Parliament has deliberately changed the definition, exception, threshold or procedure, however, an old judgment cannot be used to override the new statutory text.

Constitutional rulings are in a different category. A judgment based on Articles 14, 16 or principles of natural justice may remain relevant even though the labour statute involved in the original dispute has changed.

The Supreme Court's 2026 judgment on the meaning of “industry” provides the clearest example.

1. Does Bangalore Water Supply still decide what an “industry” is?

Only for disputes governed by the old Industrial Disputes Act. It should not be treated as controlling the new definition under the Industrial Relations Code.

In Bangalore Water Supply & Sewerage Board v. A. Rajappa, (1978) 2 SCC 213, the Supreme Court developed the famous “triple test” for determining whether an activity constituted an “industry” under Section 2(j) of the Industrial Disputes Act, 1947.

The position changed significantly on 20 August 2026.

In State of U.P. v. Jai Bir Singh, 2026 INSC 897, a nine-judge Bench considered the continuing relevance of Bangalore Water Supply after the old Act had been repealed. The judgment makes two points especially important for businesses and employment lawyers.

First, Bangalore Water Supply continues to govern relevant pending disputes arising under the repealed Industrial Disputes Act.

Second, the definition of “industry” in Section 2(p) of the Industrial Relations Code must be interpreted independently. The Court expressly said that Bangalore Water Supply should not become the “sheet anchor” for interpreting the new Code.

That means an employer facing a dispute arising under the new Code should begin with the wording of Section 2(p), not simply reproduce the old Bangalore Water Supply analysis.

Judgment: State of U.P. v. Jai Bir Singh, 2026 INSC 897

Practical position in 2026

For a legacy dispute governed by the Industrial Disputes Act, Bangalore Water Supply remains important. For a fresh dispute governed by the IR Code, Section 2(p) must be interpreted on its own language and context.

This is probably the clearest example of an old landmark judgment that survives, but only within its proper statutory territory.

2. Does Workmen of Firestone Tyre still apply to disciplinary dismissals?

Its core principles remain highly relevant because Section 50 of the Industrial Relations Code substantially preserves the Tribunal's power to examine unjustified dismissal and grant appropriate relief.

In Workmen of Firestone Tyre & Rubber Co. of India (P) Ltd. v. Management, (1973) 1 SCC 813, decided on 6 March 1973, the Supreme Court explained the powers of labour adjudicatory bodies when disciplinary action or a domestic enquiry is challenged.

Among other principles, Firestone recognised the Labour Tribunal's role in examining disciplinary action and dealt extensively with cases where an employer had conducted no enquiry or a defective enquiry.

Under the new regime, Section 50 of the IR Code gives the Tribunal or National Industrial Tribunal power, where discharge, dismissal or other termination is found unjustified, to set it aside, order reinstatement, grant other relief or impose a lesser punishment.

Because Parliament has retained a statutory remedial structure closely related to the former Section 11A of the Industrial Disputes Act, Firestone remains a significant interpretive authority.

But there is an important qualification: Firestone should be used with the wording of Section 50, not as though Section 11A of the old Act were still in force. Future Supreme Court judgments specifically interpreting Section 50 could further develop or modify how these principles operate.

Judgment: Workmen of Firestone Tyre & Rubber Co. v. Management

3. Does D.K. Yadav still require a fair hearing before termination?

D.K. Yadav remains a powerful authority on natural justice, particularly where termination is effectively based on alleged misconduct, unauthorised absence or abandonment of service.

In D.K. Yadav v. J.M.A. Industries Ltd., (1993) 3 SCC 259, decided on 7 May 1993, an employee's name had been struck off the rolls under a standing-order provision dealing with absence.

The Supreme Court held that natural justice had to be read into the standing order. An employee could not simply be treated as having automatically abandoned employment without a fair opportunity to put forward his case. The Court connected fair procedure with Articles 14 and 21 and stressed that action affecting livelihood must follow a just, fair and reasonable procedure.

That reasoning has not disappeared because the Industrial Employment (Standing Orders) Act, 1946 has been replaced.

The IR Code itself now contains a standing-orders regime in Chapter IV. However, an important change is that Section 28 applies that Chapter to industrial establishments employing 300 or more workers, or which employed that number on any day during the preceding 12 months, subject to the statutory exclusions.

D.K. Yadav therefore remains important, but it should not be converted into an overbroad statement that every form of employment termination requires a domestic enquiry. Expiry of a genuine fixed-term contract, retrenchment and disciplinary dismissal involve different statutory questions.

For employers, the practical lesson is simple: calling something “abandonment” does not necessarily make a fair process unnecessary.

4. Does Umadevi still govern regularisation of temporary or contractual employees?

Yes. Secretary, State of Karnataka v. Umadevi (3) remains binding constitutional law for public employment and was not displaced by the Labour Codes.

In Secretary, State of Karnataka v. Umadevi (3), (2006) 4 SCC 1, decided on 10 April 2006, a Constitution Bench held that regular public appointments ordinarily have to comply with the constitutional requirements of equality of opportunity under Articles 14 and 16.

Courts cannot ordinarily create a parallel route into permanent public employment by directing regularisation of persons appointed in disregard of the applicable constitutional recruitment process. The judgment also contained the well-known direction concerning a one-time consideration of certain irregular, rather than illegal, appointments of qualified persons against sanctioned posts who had served for the required period without protection of court orders.

Umadevi is principally constitutional public-employment law. The Labour Codes do not repeal Articles 14 and 16 or replace the constitutional rules governing recruitment into government service.

Its application must therefore be separated from disputes involving ordinary private-sector employees.

5. Does SAIL still mean contract workers are not automatically absorbed?

The rule against automatic absorption remains important, but the new OSHWC Code must now be applied before relying on the old Contract Labour Act cases.

In Steel Authority of India Ltd. v. National Union Waterfront Workers, (2001) 7 SCC 1, a Constitution Bench held that abolition of contract labour under the Contract Labour (Regulation and Abolition) Act, 1970 did not by itself result in automatic absorption of those workers as employees of the principal employer.

The statutory framework has now changed.

The Occupational Safety, Health and Working Conditions Code, 2020 (“OSHWC Code”) contains the current contract-labour regime. Section 57 prohibits employment of contract labour in the core activities of an establishment, subject to specified statutory exceptions.

Official text: Occupational Safety, Health and Working Conditions Code, 2020 – India Code

Therefore, SAIL remains valuable for the proposition that statutory prohibition of contract labour should not casually be converted into automatic absorption unless the governing law provides that consequence.

However, a 2026 dispute must first be analysed under the OSHWC Code—including its definition of core activity, statutory exceptions, contractor arrangements and the actual relationship between the worker and principal employer.

6. Does the 2023 Jet Airways judgment mean every worker becomes permanent after 240 days?

No. That would be an incorrect reading of the judgment, particularly under the new Labour Codes.

In Bharatiya Kamgar Karmachari Mahasangh v. M/s Jet Airways Ltd., 2023 INSC 646, the Supreme Court dealt with approximately 169 workers and the specific Bombay Model Standing Orders applicable to that dispute.

The Court held that the applicable standing order gave the relevant workers the claimed permanency benefit and that a private settlement could not override statutory standing orders.

But the judgment does not establish a universal national rule that completion of 240 days automatically converts every worker into a permanent employee.

That distinction is even more important under the IR Code because Parliament expressly recognises fixed-term employment. The Code also expressly excludes termination resulting from completion of the tenure of fixed-term employment from the definition of “retrenchment”.

The enduring principle from Jet Airways is therefore the statutory importance of applicable standing orders. Its particular 240-day consequence should not be transplanted into every employment relationship without checking the governing standing orders and the new Code.

Judgment: Bharatiya Kamgar Karmachari Mahasangh v. Jet Airways Ltd.

7. Does Punjab Land Development still define retrenchment broadly?

Yes, as an interpretive starting point—but the express exclusions in the new statutory definition must now be respected.

In Punjab Land Development and Reclamation Corporation Ltd. v. Presiding Officer, Labour Court, (1990) 3 SCC 682, the Constitution Bench interpreted “retrenchment” under Section 2(oo) of the Industrial Disputes Act broadly as termination by the employer for any reason whatsoever, apart from the categories expressly excluded by the definition.

Section 2(zh) of the Industrial Relations Code retains the broad opening concept of termination “for any reason whatsoever”, but it also contains specific exclusions. Those include voluntary retirement, superannuation in the prescribed circumstances, certain termination connected with expiry or a contractual stipulation, completion of the tenure of fixed-term employment, and termination on continued ill-health.

So the old Supreme Court reasoning remains useful for the basic principle: read the definition broadly and then apply every statutory exclusion.

It cannot be used to erase exclusions Parliament has expressly enacted in the new Code.

For an ordinary retrenchment covered by Section 70, an eligible worker with at least one year of continuous service is protected by statutory conditions including one month's notice or wages in lieu and retrenchment compensation based on fifteen days' average pay for every completed year of continuous service, or part exceeding six months, subject to the provision as enacted and any valid notification.

Separate provisions apply to establishments falling within the special Chapter X regime, so workforce size and establishment category must be checked before advising on a retrenchment.

8. Does Deepali Gundu Surwase still mean full back wages follow an illegal termination?

The judgment remains important, but full back wages should never be described as automatic in every termination case.

In Deepali Gundu Surwase v. Kranti Junior Adhyapak Mahavidyalaya, (2013) 10 SCC 324, decided on 12 August 2013, the Supreme Court discussed reinstatement and back wages where an employee had been wrongfully kept out of service.

Its principles continue to be cited in employment-remedy disputes.

However, relief depends heavily on facts. Courts and tribunals consider matters such as the nature of the illegality, length of service, nature of employment, gainful employment during the disputed period and whether reinstatement remains appropriate.

That fits with Section 50 of the IR Code, which gives the Tribunal flexibility to order reinstatement or grant other appropriate relief.

Businesses should therefore avoid both extremes: “illegal termination always means full back wages” is too broad, but so is “back wages can never be awarded”.

Which old judgments should businesses be most careful about relying on?

The safest method in 2026 is not to ask merely whether an old case is “still good law”. Ask what exact proposition you are trying to use it for.

For example, Bangalore Water Supply remains relevant to pending disputes under the repealed Industrial Disputes Act but does not control Section 2(p) of the IR Code. Firestone remains strongly relevant because comparable tribunal powers continue under Section 50. D.K. Yadav continues to carry significant natural-justice reasoning, but it does not turn every contractual expiry into misconduct proceedings. Umadevi continues in public employment because its foundation is constitutional. SAIL remains important on automatic absorption, but the OSHWC Code must now be applied. Jet Airways remains useful on the statutory force of standing orders, but its specific 240-day result was based on the standing orders governing that case.

That is the central lesson of labour-law precedent after the Codes: use the judgment only after identifying the present statutory provision.

What should an employer check before relying on a pre-Code judgment?

A practical 2026 review should check: when the cause of action arose; whether the old law or new Code governs it; which Code and section now regulate the issue; whether the wording changed; whether there is a saving or transition provision; whether Central or State rules apply; whether the employee is a “worker” within the relevant statutory definition; the size and category of the establishment; and whether a later Supreme Court judgment has restricted the older precedent.

This sequence matters more than simply searching for the most famous labour-law case.

Frequently Asked Questions

Did the Labour Codes come into force in 2026?

No. The Government made the four Labour Codes effective from 21 November 2025. Important rules and transitional measures followed in 2026, which is why employers dealing with disputes in 2026 need to check both the Codes and the subsequent rules and notifications.

Are all judgments under the Industrial Disputes Act now useless?

No. Some continue to govern legacy proceedings, while others remain persuasive where materially similar provisions have been carried into the IR Code. Their relevance must be assessed provision by provision.

Does Bangalore Water Supply apply to Section 2(p) of the Industrial Relations Code?

It should not be treated as controlling Section 2(p). In Jai Bir Singh (2026), the Supreme Court made clear that the new definition is to be interpreted independently on the text and context of the IR Code.

Does completing 240 days automatically make a worker permanent?

No. The significance of 240 days depends on the statutory provision and issue involved. The Jet Airways decision involved a specific Bombay Model Standing Order; it is not a universal rule converting every employee into a permanent employee after 240 days.

Can an employer terminate a worker for abandonment without hearing them?

An employer should be very cautious. D.K. Yadav establishes an important natural-justice principle against treating alleged absence as automatic abandonment where serious civil consequences follow. The applicable Code, standing orders, contract and facts must still be examined.

Are fixed-term employees permitted under the Industrial Relations Code?

Yes. The IR Code expressly recognises fixed-term employment, with statutory conditions attached to that category. Completion of the tenure of fixed-term employment is also expressly excluded from “retrenchment” under Section 2(zh).

Does abolition or prohibition of contract labour automatically make workers employees of the principal employer?

The SAIL Constitution Bench rejected automatic absorption under the earlier CLRA Act. Under the current regime, the OSHWC Code must now be examined, including Section 57 and the facts concerning the real employment relationship.

Do the Industrial Relations (Central) Rules, 2026 apply to every employer in India?

Not necessarily. They are Central Rules. The identity of the “appropriate Government” and applicable Central or State rules and notifications must be checked for the particular establishment.

Final takeaway

The new Labour Codes did not wipe out decades of Supreme Court employment jurisprudence. What they changed is the statutory framework against which those judgments must now be read.

The strongest precedents in 2026 fall into three broad categories: constitutional principles that continue independently of the repealed statutes; decisions interpreting concepts substantially retained in the Codes; and legacy judgments that remain applicable only to disputes governed by the old law.

The Supreme Court's 2026 decision in State of U.P. v. Jai Bir Singh provides the most useful warning against mechanical reliance on old authorities: where Parliament has enacted a new definition, courts must interpret the new law from its own text, scheme and context.

For employers, HR teams and advocates, the safest order is therefore Code first, current rules second, facts third, precedent fourth.
