State of Karnataka v. Umadevi (3): the Constitution Bench that closed the door on regularisation-by-mandamus

For close to two decades before 10 April 2006 the Supreme Court had carried on its books a body of jurisprudence under which long-serving casual, daily-wage and ad hoc employees in the public sector could obtain, by writ petition under Article 226 or by litigation before service tribunals, an order directing the State to regularise their service. The pattern was steady. The employee, taken on as a casual labourer or a daily-wage worker, would render service for years. The State would not regularise. The employee would approach the High Court. The High Court, drawing on cases such as Daily Rated Casual Labour Employed under P&T Department v. Union of India, (1988) 1 SCC 122, Dharwad Distt. PWD Literate Daily-Wage Employees Association v. State of Karnataka, (1990) 2 SCC 396, and Ashwani Kumar v. State of Bihar, (1997) 2 SCC 1, would direct regularisation — sometimes with retrospective benefits, often without any examination of whether the underlying appointment had ever satisfied Article 16.

That line of jurisprudence was brought to a close on 10 April 2006. A five-judge Constitution Bench of Y.K. Sabharwal CJ, Arun Kumar J., G.P. Mathur J., C.K. Thakker J. and P.K. Balasubramanyan J. — the judgment authored by Balasubramanyan J. — delivered Secretary, State of Karnataka v. Umadevi (3), (2006) 4 SCC 1, holding unanimously that public employment is governed by the discipline of Article 16, that temporary or casual appointments made outside that discipline create no fundamental right to permanency, that the High Courts under Article 226 and service tribunals have no power to direct absorption or regularisation of such appointees, and that the earlier line of cases that had operated on a contrary premise stood overruled.

Its operative parts are concentrated in paragraphs 43 to 54. Paragraph 53, in particular, fashioned the narrow exception that has framed every subsequent regularisation dispute. The judgment is, two decades on, still the gravitational centre of public-employment jurisprudence in India.

The architecture of the dispute

The cases consolidated before the Constitution Bench arose principally from the State of Karnataka and concerned workers engaged in the Commercial Tax Department on daily wages and on consolidated pay over extended periods — in some matters more than ten years — without recourse to the recruitment procedure prescribed by the Karnataka Civil Services (Classification, Control and Appeal) Rules and the cadre rules made under the proviso to Article 309. The workers had moved the Karnataka Administrative Tribunal and, on appeal, the Karnataka High Court, for a direction that they be regularised against the posts they had been performing the duties of. The High Court had directed the State to consider regularisation. The State carried the matter to the Supreme Court.

The matter was referred to a Constitution Bench because the line of decisions on which the High Court had relied had created a doctrinal tension with a parallel line of authority — State of Haryana v. Piara Singh, (1992) 4 SCC 118 and J. & K. Public Service Commission v. Narinder Mohan, (1994) 2 SCC 630 — that had insisted on Article 16 compliance as the entry-point to public employment. The Constitution Bench reference was the long-deferred reconciliation.

The factual matrix the Bench worked with

Three features of the petitioners' service shaped the constitutional question. First, none of the petitioners had been recruited through the procedure prescribed for entry into public service — there had been no advertisement, no examination, no selection by the Public Service Commission or by the recruiting authority empowered under the cadre rules. Second, several of the petitioners had been engaged against duly sanctioned posts that lay vacant, but the engagements were not made through the prescribed recruitment process; a smaller subset had been engaged against posts that were not sanctioned at all, or against project-tied positions that were not part of the regular cadre. Third, the petitioners had served for periods ranging from a few years to well in excess of a decade, and many of them held interim orders from various courts that had protected their continuance during the pendency of their litigation.

The Bench treated those three features as the doctrinal hinges of the case. The first — non-compliance with Article 16 — supplied the constitutional starting point. The second — the distinction between engagements against sanctioned posts and engagements outside the sanctioned cadre — supplied the doctrinal axis on which the irregular / illegal distinction was built. The third — long service often sheltered by interim protection — supplied the equitable pressure that paragraph 53 was crafted to relieve, but only on terms.

The reasoning

Article 16 as the constitutional baseline

The first thread in Balasubramanyan J.'s reasoning is the simplest and the most consequential. Article 16(1) of the Constitution guarantees equality of opportunity in matters of public employment; Article 16(4) permits reservation in favour of backward classes. Both clauses presuppose a recruitment process that is open, advertised, competitive and accessible to all eligible candidates. Where the State engages employees outside that process — by direct engagement, by contractor-route engagement, by project-tied engagement — it bypasses the constitutional guarantee that Article 16 confers on every citizen, not merely those whom the State has chosen to engage.

The Bench held that the conferment of a fundamental right to regularisation on such engagees would, in operation, perpetuate the breach of Article 16 and would deprive the wider pool of eligible aspirants of the opportunity that the Constitution guarantees them. The Court framed the question in candid terms: the constitutional right under Article 16 belongs to every citizen who would have competed for the post had it been advertised, not to the individual who happens to have been engaged without competition.

That framing inverted the equitable starting point of the Dharwad PWD line. Under that earlier line, the long-serving casual employee was the visible petitioner before the Court, the State the obvious wrongdoer, and the equitable instinct ran in favour of regularisation. Under Umadevi, the absent eligible aspirant — the citizen who never applied because the post was never advertised — is the unseen but constitutionally weighty interest that the Court must protect.

The irregular / illegal distinction

The second thread is the operative doctrinal axis. Balasubramanyan J. drew a line between two categories of appointments made outside the Article 16 procedure. An irregular appointment is one made against a duly sanctioned post — a post that exists in the cadre, is funded and vacant — but without compliance with the full recruitment procedure prescribed for that post. An illegal appointment is one made against a post that does not exist in the cadre at all — a non-sanctioned position, a project-tied engagement outside the regular cadre, or an engagement made in defiance of a recruitment ban.

The doctrinal consequence of the distinction is sharp. An irregular appointee may, on the State's policy decision, be considered for one-time regularisation under the terms of paragraph 53. An illegal appointee may never be regularised — no court direction, no policy decision, no length of service can confer on such an appointee a right against a post that the Constitution would not recognise as an entry-point into public service.

The distinction has carried the entire weight of regularisation jurisprudence since 2006. The first question that every High Court and tribunal asks in a regularisation petition is whether the appointment was against a sanctioned post — and if so, whether the recruitment procedure was bypassed (irregular) or whether the post itself was outside the cadre (illegal). The answer to that question, more than any other, determines the outcome.

The limits on Article 226 and the tribunals

The third thread is jurisdictional. The High Courts under Article 226 and the service tribunals had, on the strength of the Dharwad PWD line, been issuing directions to the State to regularise casual and daily-wage employees. The Bench held that those directions had no constitutional foundation. The High Court's writ jurisdiction does not extend to creating posts; does not extend to overriding the recruitment procedure prescribed by valid statutory rules; and does not extend to conferring on individual petitioners a status — that of regular public servant — that the Constitution reserves to those who have entered service through Article 16.

The Bench was careful to identify what Article 226 may still do in this field. The High Court may correct a State that has refused to follow its own validly-framed regularisation policy. It may strike down arbitrary terminations of casual or daily-wage employees on grounds independent of the regularisation question — under Article 14 or under industrial-relations statutes that apply. It may direct that equal pay for equal work be honoured where the post and the duties match the regular cadre, even in the absence of regularisation. What Article 226 may not do is to direct the State to confer permanency on an appointee who has never entered through the Article 16 gate.

Paragraph 53 — the one-time, fixed-date exception

The fourth thread is the equitable balance. Balasubramanyan J. was alive to the human cost of long service rendered, often in good faith, under State engagements that the State itself had perpetuated for years. The Bench's response was paragraph 53. The State may, taking the decision as one of policy and after the date of the judgment, regularise the services of those irregularly appointed persons — that is, persons working against sanctioned posts but without recourse to the Article 16 procedure — who have continued in service for ten years or more as of the date of the judgment, namely 10 April 2006. The paragraph 53 exception is, in the Bench's express terms, a one-time measure: it is anchored to the date of the judgment and does not generate a continuing, rolling ten-year right to regularisation for those whose engagements postdated 10 April 2006 or who completed ten years thereafter.

That fixed-date character of paragraph 53 is the single most-misunderstood part of Umadevi. The temptation to read the paragraph as a continuing rule — that any irregular appointee who completes ten years acquires a right to be considered for regularisation, no matter when the ten years are completed — has been a perennial source of misdirected litigation. The Supreme Court has had to clarify, in State of Karnataka v. M.L. Kesari, (2010) 9 SCC 247, that the ten-year window is fixed to 10 April 2006 and is not a continuing rolling rule; M.L. Kesari extended only a narrow refinement that the period of service rendered under court-protected interim orders may be excluded from the computation of the ten years in appropriate cases, but did not disturb the fixed-date character.

The overruling

The Bench expressly overruled Daily Rated Casual Labour Employed under P&T Department v. Union of India, Dharwad Distt. PWD Literate Daily-Wage Employees Association v. State of Karnataka, and Ashwani Kumar v. State of Bihar. It treated the related line of cases — including Piara Singh and Narinder Mohan — as broadly consistent with the constitutional baseline it had restated. The overruling was clean: the new doctrinal architecture replaced the older one prospectively from 10 April 2006, with paragraph 53 supplying the equitable cushion for cases caught by the transition.

The doctrinal contribution

Umadevi's doctrinal contribution operates at five levels.

First, it installs the proposition that regularisation is not a fundamental right. The right that Article 16 guarantees is the right of every citizen to compete on equal terms for public employment, not the right of a particular engagee to be confirmed in service. That reorientation is the heart of the judgment.

Second, it supplies the irregular / illegal distinction that has, since 2006, structured every regularisation petition before the High Courts and tribunals. The test is simple to state and operative in application: is the post sanctioned and within the cadre, or is it not?

Third, it fixes the one-time, date-anchored character of the paragraph 53 exception. The ten-year window is not a continuing rule. The Supreme Court's restatement in M.L. Kesari has held the line.

Fourth, it cabins the writ jurisdiction under Article 226 in this field. High Courts may not direct regularisation, may not create posts, may not order absorption against the State's recruitment scheme. They may still correct arbitrary terminations, enforce equal pay for equal work where the comparator is genuine, and police the State's compliance with its own regularisation policies.

Fifth, it ends the era of regularisation-by-mandamus. The decade following Umadevi saw a steady reduction in the volume of writ-driven regularisation litigation, and a corresponding shift to State-led regularisation policies — many of them framed in the years 2006 to 2010 to give effect to the paragraph 53 cushion — operating within the constitutional baseline the Bench had restored.

What the judgment did not decide

Three matters Umadevi expressly left open or did not reach.

First, the Bench did not work through the application of its reasoning to employees of statutory corporations whose service conditions are governed by regulations rather than by Article 309 rules. The judgment is framed in terms of "public employment" governed by Article 16; the translation to statutory-corporation employment — where Sukhdev Singh v. Bhagatram, (1975) 1 SCC 421 supplies the architecture — has been worked out case by case.

Second, the Bench did not address the industrial-relations route. Workers denied the status of permanent workmen under the Industrial Disputes Act 1947 or State unfair-labour-practice statutes retain a parallel statutory remedy. Maharashtra State Road Transport Corpn v. Casteribe Rajya Parivahan Karmchari Sanghatana, (2009) 8 SCC 556 confirmed that Umadevi operates within its own constitutional field and does not bar industrial-court relief.

Third, the Bench did not work through the gig and platform worker question that has surfaced more recently. The application of Umadevi's logic to engagements that are formally contractual but functionally permanent has been the subject of litigation through 2024-2026; the courts have generally read Umadevi as confined to the Article 16 public-employment field.

The downstream jurisprudence

The post-Umadevi line has worked at three levels.

At the level of paragraph 53 implementation, State of Karnataka v. M.L. Kesari, (2010) 9 SCC 247 clarified the fixed-date character of the ten-year window and held that periods served under court-protected interim orders may be excluded from the computation in appropriate cases. Nihal Singh v. State of Punjab, (2013) 14 SCC 65 — concerning Special Police Officers engaged in Punjab — applied the Umadevi framework while recognising the State's affirmative obligation to consider regularisation where the engagement had filled a sanctioned cadre need. Narendra Kumar Tiwari v. State of Jharkhand, (2018) 8 SCC 238 worked through the paragraph 53 computation in the context of regularisation policies framed after 10 April 2006.

At the level of State-led regularisation policies, several States framed schemes in the years 2006 to 2010 to give effect to paragraph 53. The Supreme Court has, in subsequent rulings — most recently in Sukhendu Bhattacharjee v. State of Assam, 2026 INSC 523 — treated Umadevi as a shield against compelled regularisation by writ, but not as a sword that the State can wield to deny equal treatment among similarly-placed irregular appointees once it has framed a policy and acted on it. The doctrinal direction in Sukhendu Bhattacharjee is significant: the State, having chosen to regularise some irregular appointees on a policy, cannot invoke Umadevi to refuse comparable treatment to those who satisfy the same criteria.

At the level of adjacent service-law disputes, Bhola Nath v. State of Jharkhand, 2026 INSC 99 — decided 30 January 2026 in respect of Junior Engineers (Agriculture) who had been selected through a prescribed process in 2012 and retained on year-to-year extensions for over a decade against sanctioned vacant posts — applied a "model employer" gloss on the Umadevi architecture, directing regularisation where the post was sanctioned, the selection had followed a due process and the State's own conduct over thirteen years had treated the engagement as substantive. The decision is best read not as a departure from Umadevi but as a careful application of the irregular limb of its taxonomy in a case where the equitable balance ran clearly in the workers' favour.

What practitioners take from Umadevi

For the service-law bar, the operational guidance is straightforward.

The first question is the character of the post. Counsel for a regularisation petitioner must establish, at the threshold, that the post against which the petitioner served was a duly sanctioned post within the cadre and that the engagement was irregular rather than illegal. Without that finding, the petition cannot get past the Umadevi gate.

The ten-year computation is anchored to 10 April 2006. A petitioner who completed ten years of service after that date cannot rely on paragraph 53 standing alone. The petitioner's case has to be made on a different doctrinal basis — typically a State-framed regularisation policy that the State has applied unequally (the Sukhendu Bhattacharjee route), an industrial-relations claim under unfair-labour-practice statutes (the Casteribe route), or an Article 14 claim against arbitrary termination.

Article 226 directions to regularise are not available. The High Court cannot, on its own writ jurisdiction, order the State to regularise. The petitioner's request must be framed in terms the High Court can deliver — a direction to the State to consider, under its own policy, the petitioner's case; a direction against arbitrary termination; a direction to honour equal pay for equal work; a direction to comply with an industrial tribunal's award. The framing matters.

For the State, the discipline runs the other way. Once a regularisation policy is framed and applied to a class of irregular appointees, the State cannot rely on Umadevi to deny comparable treatment to similarly-placed appointees within the class. Umadevi is a shield against being compelled to regularise; it is not a sword for the State to wield unequally.

For the gig-economy and platform-worker bar, the doctrinal reach of Umadevi is confined to the Article 16 public-employment field. The cases that test employee-status claims against aggregators and platforms run on a different doctrinal track — industrial-relations statutes, the Code on Social Security 2020, and the May 2026 Social Security (Central) Rules operationalising the gig and platform worker framework. Umadevi does not foreclose those routes; it is simply not the relevant authority.
