SAIL v. National Union Waterfront Workers: the Constitution Bench overrules Air India SC

The facts in brief

On 15 July 1989, the Government of West Bengal issued a notification under Section 10(1) of the Contract Labour (Regulation and Abolition) Act, 1970, prohibiting the employment of contract labour in four specified stockyards of the Steel Authority of India Limited (SAIL) at Calcutta. SAIL had used contractors at these stockyards for handling, loading, unloading and transportation of steel products. The National Union Waterfront Workers — representing the contract workmen — claimed automatic absorption into SAIL on the strength of Air India Statutory Corporation v. United Labour Union (1997) 9 SCC 377.

SAIL's defence ran along two lines. First, the State of West Bengal was not the "appropriate Government" for SAIL — SAIL is a central public sector undertaking; the appropriate Government was therefore the Centre, and the 15 July 1989 State notification was ultra vires. Second, even assuming the notification's validity, no automatic absorption flowed from it — the Air India SC reading of Section 10 was incorrect and had been arrived at in disregard of an earlier coordinate-bench decision.

The Calcutta High Court applied Air India SC and directed absorption. SAIL appealed to the Supreme Court. The matter was consolidated with a companion batch of appeals — thirty-eight in number — raising similar issues at other central PSUs and under multiple State notifications.

A two-judge bench, conscious of the conflict between Air India SC (1997) on one side and R.K. Panda v. SAIL (1994) 5 SCC 304 + Hindustan Steel Workers Construction v. Commissioner of Labour (1996) 10 SCC 599 on the other, referred the matter to a larger bench. The Chief Justice constituted a five-judge Constitution Bench — Kirpal, Quadri, M.B. Shah, Ruma Pal and Balakrishnan JJ. The hearings ran through 2001. Judgment was delivered on 30 August 2001.

The "appropriate Government" question

The Constitution Bench addressed the threshold question first. Section 2(1)(a) CLRA defines "appropriate Government" for an industry by reference to whether the industry is carried on by or under the authority of the Central Government — or whether it is a railway, a controlled industry, or one falling within a specific central enumeration.

The bench held that "carried on by or under the authority of" the Central Government is a functional test, not a status test. Mere ownership of equity in a central PSU does not vest the Centre with "authority" over the PSU's day-to-day industry. For SAIL, the SAIL Act did not transfer authority over the Calcutta stockyards to the Union; the appropriate Government was accordingly the State of West Bengal, and the 1989 notification was valid.

This holding partly narrowed Air India SC's broader reading — central-PSU status alone was not enough. The reasoning in Air India SC on this point was held to be too wide.

The automatic-absorption holding

On the central question, the Constitution Bench overruled Air India SC. The reasoning was textual, structural and remedial in turn.

Textually, Section 10 contains no language of absorption. It empowers the appropriate Government, after consulting the Central or State Advisory Board, to prohibit the employment of contract labour in a specified process. The section says nothing about what becomes of the workers — it does not create a deeming provision, does not fix a date of absorption, does not provide for fitment into pay scales. A judicial gloss that reads absorption into the text rewrites the section.

Structurally, the CLRA Act 1970 distinguishes between regulation (Chapters II to V — registration, licensing, welfare facilities, wage payment) and prohibition (Section 10). The regulation chapters apply where contract labour continues; the prohibition operates where the appropriate Government determines the conditions in Section 10(2) are satisfied. The Act's scheme assumes that, on prohibition, the contractor stops engaging workers for that process and the principal employer either takes on direct employees or does not undertake the work — the statute does not legislate a particular outcome for the displaced workers.

Neither Section 10 of the CLRA Act nor any other provision in the Act, whether expressly or by necessary implication, provides for automatic absorption of contract labour on issuance of a notification by the appropriate Government under sub-section (1) of Section 10, prohibiting employment of contract labour in any process, operation or other work in any establishment. Consequently, the principal employer cannot be required to order absorption of the contract labour working in the concerned establishment.

Remedially, the bench held that the route for a displaced worker is industrial adjudication under Section 10 of the Industrial Disputes Act, 1947. A reference to the Labour Court or Industrial Tribunal allows the dispute to be examined on its facts: whether the contract was sham; whether the worker had a direct master-servant relationship with the principal employer; what relief is appropriate. This is the route the CLRA's scheme assumes — the writ court, on the contrary, has no machinery to make these factual findings in absorption claims.

The prospective-overruling formula

The Constitution Bench was conscious that thousands of contract workers had been absorbed during the 1996-2001 window on the strength of Air India SC. To unwind those absorptions would be administratively chaotic and individually unjust. The bench accordingly applied prospective overruling.

The formula: (i) final orders and decrees passed under Air India SC are preserved; (ii) actual absorptions effected pursuant to Air India SC are not disturbed; (iii) wages paid to absorbed workers in the interim are neither recoverable from the workers nor refundable to the principal employer; (iv) the new rule — no automatic absorption — applies from 30 August 2001 onwards.

This formula has subsequently been treated as a model for prospective overruling in labour matters where unwinding equities would produce greater injustice than the corrective.

The sham-contract exception

The Constitution Bench expressly preserved one category in which the principal employer can be held directly liable to absorb workers — the sham or camouflage contract. Where the contract-labour arrangement is a subterfuge — where the contractor is a paper entity, the workers are in substance employees of the principal employer, the wage payments pass through the contractor only formally — the industrial adjudicator can pierce the corporate veil and hold the principal employer to be the real employer.

The threshold for sham-contract treatment is high. The contractor's separate juridical existence, payment of statutory dues, deployment of supervisors, and exercise of disciplinary control are all relevant factors. The presumption is against sham-contract characterisation; the worker bears the burden of demonstrating it on the facts. The bench did not lay down an exhaustive list of indicia — leaving the development to case-by-case adjudication.

The exception has become the principal litigated frontier in the two decades since SAIL. International Airport Authority v. International Air Cargo Workers Union (2009) 13 SCC 374, General Manager OPTCL v. Roshan Bhuyan (2012) 8 SCC 524, and Hindalco Industries v. Association of Engineering Workers (2008) 13 SCC 441 each address the sham-contract test in different settings.

What the judgment did not decide

SAIL did not decide several adjacent questions that would be litigated afterwards.

It did not address the outsourcing architecture that proliferated after 2001 — housekeeping, security, IT-services and facilities-management contracts that look formally distinct from old-style contract labour. Whether the Section 10 framework reaches modern outsourcing arrangements, and whether the sham-contract test extends to long-duration service contracts where the workers' work is integrated with the principal employer's core activity, has been worked out incrementally by High Courts and the Supreme Court since.

It did not address the constitutional status of contract labour as an institution. The labour-rights critique that contract labour itself is an Article 21 / Article 23 problem — endorsed by Krishna Iyer J in earlier dicta — was left unaddressed.

It did not decide the preference question — whether displaced workers must be given preference in fresh hiring by the principal employer for regular positions. The bench observed that such preference would be desirable but stopped short of mandating it. State PSUs and central PSUs have implemented preference schemes administratively, with varying coverage.

It did not address the inter-State migrant workers under the Inter-State Migrant Workmen Act 1979, whose position remained governed by that Act's separate framework.

The post-SAIL landscape

SAIL is the operative law on contract-labour absorption today. Three doctrinal pillars define the post-SAIL position.

First, the writ-jurisdiction route is closed for direct absorption. State of Karnataka v. Umadevi (3) (2006) 4 SCC 1, a five-judge Constitution Bench in a related setting, held that Article 226 jurisdiction does not extend to regularising irregular or temporary appointments — dovetailing with SAIL's anti-judicial-regularisation philosophy. The two judgments together produce a regime in which contract workers cannot recover their position through constitutional writ.

Second, industrial adjudication is slow. A reference under Section 10 ID Act takes years to reach an award; the award is appealable; the workers in the meantime lose their employment. The remedial inadequacy of the SAIL route has been the principal trade-union complaint about the decision.

Third, the labour-codes consolidation does not displace SAIL. The Occupational Safety, Health and Working Conditions Code, 2020 — Sections 57 to 71 — absorbs the CLRA Act 1970. The Code reproduces the Section 10-style prohibition mechanism but does not statutorily provide for absorption. The legislative inertia is, by now, deliberate: Parliament has had two decades to overrule SAIL legislatively and has not done so.

Why the case still matters

SAIL is the most-cited contract-labour decision in Indian law. Three reasons it continues to matter.

First, the constitutional method. The Constitution Bench took a welfare statute and refused to bend its text on purposive grounds where the text would not bear the bending. This is a method that has been invoked by later benches in other labour and economic-regulation settings — that purposive interpretation cannot rewrite a statute Parliament chose to leave silent.

Second, the sham-contract frontier. The exception has become the principal litigation site for permanent contract workers seeking regularisation. Each year produces a fresh crop of awards and SLPs working out the indicia.

Third, the Code-readiness implication. As the OSH Code commences in stages — Section 1(3) notifications are still awaited as of June 2026 — the SAIL framework will govern the prohibition mechanism's downstream consequences. Compliance audits for principal employers in central PSUs, port and dock operations, and infrastructure projects continue to be drawn against the SAIL safeguards.
