What Is a Trade Union in Indian Law? Registration, Rights, and Immunities Under the Trade Unions Act, 1926.

When workers in a factory decide to form a combination to collectively demand better wages, they are exercising a right that took over a century of legal and political struggle to establish. Before the Trade Unions Act, 1926, that same combination could have been prosecuted as a criminal conspiracy. After it, the Act placed collective worker action within a framework of legal protection.

India’s trade union law is older than independence, older than the Constitution, and older than the Industrial Disputes Act, 1947. The Trade Unions Act, 1926 — enacted under British rule — remains the foundational legislation governing the formation, registration, and immunities of trade unions in India. Its structure is deceptively simple: a definition, a registration procedure, a set of objects for which union funds can be used, and two immunities — one criminal, one civil — that protect legitimate union action from prosecution and suit.¹

Three questions structure this article. What is a trade union for the purposes of Indian law? What does registration under the Act confer, and what is its procedure? And what are the limits of the criminal and civil immunities that registration provides?

I. The Definition: What Is a Trade Union

Section 2(h) of the Trade Unions Act, 1926 defines “trade union” as any combination, whether temporary or permanent, formed primarily for the purpose of regulating the relations between workmen and employers, or between workmen and workmen, or between employers and employers, or for imposing restrictive conditions on the conduct of any trade or business — and includes any federation of two or more trade unions.¹

The definition is deliberately broad and functional rather than formalistic. It turns on purpose, not structure. A combination need not be permanent, formally registered, or even committed to writing. A temporary group of workers formed to press a specific demand can qualify as a trade union the moment its primary object satisfies the statutory test. What matters is the primary purpose — regulating employment relations, trade relations, or imposing restrictive conditions on the conduct of business. That purpose must dominate.

The phrase “formed primarily for the purpose” is the gatekeeper. An association whose dominant objects are benevolent, charitable, or social — even if it incidentally touches employment matters — does not qualify. The Madras High Court illustrated this sharply in The Tamil Nad Non-Gazetted Government Officers’ Union v. The Registrar of Trade Unions, Madras (AIR 1962 Mad. 234), where the court refused registration because the society’s objects were framed as “benevolent and ameliorative” rather than aimed at regulating employment relations through collective bargaining. The court scrutinised the constitution and rule book, found no primary regulatory purpose, and held that the association did not fall within Section 2(h).²

The relational scope of the definition covers three scenarios. First, worker unions — the classic case of employees collectively bargaining with management. Second, associations of workers dealing with other workers — craft-jurisdiction agreements, demarcation rules, inter-union arrangements. Third, and often overlooked, employers’ associations — industry federations that collectively negotiate wage structures or terms with labour unions. The statute is neutral between sides of the bargaining table. An employers’ combination that primarily exists to regulate employment relations is a trade union for all purposes under the Act, including registration and immunity.

The definition “includes any federation of two or more trade unions,” capturing umbrella bodies and apex organisations like national labour centrals.

Section 2(g) supplies the companion definition of “workman”: all persons employed in trade or industry, whether or not in the employment of the employer with whom the trade dispute arises. This is wider than the Section 2(s) “workman” definition in the Industrial Disputes Act, 1947. It does not tie the status to the specific employer in any given dispute; it looks to employment in the broader field of trade or industry. This enables solidarity actions and collective organising across a sector rather than only within a single employer’s workforce.

The “trade or industry” requirement is the outer boundary. Not every employment relationship falls within it. Purely personal or sovereign functions of the state are excluded — a point developed in the government employees section below. The definition connects directly to the larger “industry” jurisprudence developed under the Industrial Disputes Act, most authoritatively in Bangalore Water Supply and Sewerage Board v. A. Rajappa (1978) 2 SCC 213, a seven-judge bench that substantially expanded what counts as “industry” in Indian labour law.³

A trade union under Indian law is therefore defined by what it does, not by what it calls itself or how long it has existed.

II. Who Can Register a Trade Union

Registration is not compulsory. A combination that satisfies the Section 2(h) definition is a trade union even without approaching the Registrar. But the practical and legal advantages of registration are so substantial that virtually every serious workers’ or employers’ organisation seeks it — and for good reason.

Section 3 permits any seven or more members of a trade union to apply for registration. The application goes to the Registrar of Trade Unions appointed under Section 3.¹ Section 5 mandates the particulars to be filed with the application:

• The name and address of the trade union
• Names, ages, addresses, and occupations of the members making the application
• Titles, names, ages, addresses, and occupations of the office-bearers
• A copy of the rules of the union
• If the union has existed for more than one year, a statement of assets and liabilities

Section 6 prescribes what the rules themselves must contain: the union’s name, the whole of its objects, the purposes for which general funds may be spent (expressly limited to those in Section 15), maintenance of a membership list, admission conditions, subscription levels, audit provisions, the procedure for amending rules, the manner of appointment and removal of office-bearers, safe custody of funds, and provisions for dissolution. These are not formalities. They are the minimum governance architecture of a valid union.⁴

The Registrar may call for further information under Section 7. But once the statutory requirements are satisfied, Section 8 makes registration mandatory. The language of Section 8 is clear: “The Registrar on being satisfied that the Trade Union has complied with all the requirements of this Act in regard to registration shall register the Trade Union.” There is no discretionary refusal of a compliant application. The Supreme Court reinforced this in Food Corporation of India Staff Union v. Food Corporation of India (AIR 1995 SC 1344), affirming that the Registrar’s function at the registration stage is to verify compliance — not to sit in judgment over labour politics or predicted conduct.⁵

The Calcutta High Court in In Re Inland Steam Navigation Workers’ Union (AIR 1936 Cal. 59) made the same point: the Registrar cannot refuse registration of a union whose objects are within the Act on the speculation that the applicant union is a continuation of a previously proscribed association. Proof is required; suspicion is insufficient. If the objects and requirements of the Act are met, registration follows.⁶

If the Registrar refuses, Section 11 provides an appeal to the Industrial Court or, where none exists, to the High Court.

Section 9 provides that the certificate of registration issued under Section 8 is conclusive evidence that the trade union has been duly registered. Then Section 13 confers corporate personality: the registered trade union becomes a body corporate with perpetual succession, a common seal, the power to acquire and hold property, power to enter contracts, and the ability to sue and be sued in its own name.¹

Registration is therefore transformative, not administrative. It converts a private combination into a legal person. It also marks the decisive line between an organised union protected by the Act’s immunities and an unregistered association that may share the same collective aims but receives none of the Act’s specific legal protection.

III. Government Employees and the Sovereign Functions Exception

The most frequently examined question in this topic is whether government employees can form and register trade unions. The answer turns not on the identity of the employer — “the government” — but on the character of the work being done.

The Act’s definitions require persons employed in “trade or industry.” The sovereign functions exception removes certain government activities from that category entirely.

The foundational case is Rangaswami v. Registrar of Trade Unions (AIR 1962 Mad. 231). Workers at the Madras Raj Bhavan applied for registration. The Madras High Court refused. The employer — the state acting through the Governor — was not engaged in any trade or business. The services rendered by Raj Bhavan employees were purely personal, provided to the Governor and state guests in a non-commercial context. There was no “industry” and therefore no qualifying “workmen.”⁷

The Tamil Nad Non-Gazetted Government Officers’ Union v. The Registrar of Trade Unions (AIR 1962 Mad. 234) refined the analysis into a three-category framework that remains the standard reference point.²

Category 1 — Pure sovereign functions: employees of departments performing the essential, inalienable, regal functions of government — the judiciary, police, armed forces, core revenue enforcement, treasury — cannot form trade unions. Their work is outside “industry” because it constitutes state power exercised as such, not production or distribution of goods or services in any commercial sense. The Tamil Nadu court drew on the Supreme Court’s formulation in State of Bombay v. Hospital Mazdoor Sabha (AIR 1960 SC 610) that “regal functions are inescapable and inalienable” and outside the statute.⁸

Category 2 — Quasi-commercial and industrial undertakings of the state: railways, nationalised banks, public sector factories, insurance corporations, transport corporations, warehousing entities — these are industrial activities conducted by the state. Their employees are “workmen” in “industry” regardless of the employer’s public character, and can form and register trade unions.

Category 3 — Intermediate and welfare functions: educational institutions, hospitals, research institutes, welfare departments. This category was contentious in 1962 and has been substantially clarified by Bangalore Water Supply and Sewerage Board v. A. Rajappa (1978) 2 SCC 213. The seven-judge bench in that case established the triple test for “industry” under the Industrial Disputes Act: systematic activity; organised cooperation between employer and employee; production or distribution of goods or services. Hospitals, universities, clubs, and research institutes that satisfy this test are now treated as “industry” — which means their employees generally qualify to form trade unions.³

The sovereign-functions exception therefore survives but is narrower than the 1962 cases suggested. The correct analytical sequence is: first, identify the character of the work; second, apply the triple test from Bangalore Water Supply; third, assess whether the sovereign functions exception removes the activity from “industry.” Only core regal functions — those that no private actor could perform and which constitute the exercise of state power directly — remain outside the framework.

IV. Objects for Which Funds May Be Used — Section 15

A registered trade union’s general funds are not freely disposable. Section 15 exhaustively lists the objects on which they may be spent:⁴

(a) salaries, allowances, and expenses of officers of the trade union; (b) expenses of administration, including audit of accounts; (c) prosecution or defence of legal proceedings to which the union or any member is a party, when undertaken to secure or protect union or member rights arising out of employment; (d) conduct of trade disputes on behalf of the union or any member; (e) compensation to members for loss arising from trade disputes; (f) allowances to members or their dependants on death, old age, sickness, accident, or unemployment; (g) issue of, or undertaking guarantees for, loans raised by the registered trade union; and (h) publication of educational, labour, or trade union literature.

Expenditure outside this list is ultra vires. A general fund used to donate to a political party, to fund social events unrelated to labour matters, or to pay for activities not connected to employment relations and the Act’s purposes is an unlawful application of union money.

Section 16 carves out a distinct political fund. A registered trade union may separately constitute and maintain a fund — kept entirely apart from the general fund — for specified political objects: donations to political candidates, payment of election expenses, holding political meetings, and publishing political literature. No member may be compelled to contribute to the political fund as a condition of membership. This last requirement is critical — political participation is voluntary, never coerced.⁴

The separation between general and political funds is not merely an accounting rule. It reflects a considered legislative choice: trade unions have always had a political dimension alongside their economic one, and the Act acknowledges both, but insists that the worker who joins a union for economic protection is not thereby conscripted into any political cause.

V. Criminal Immunity Under Section 17

Section 17 is the shield against criminal conspiracy charges. Its text provides that no officer or member of a registered trade union shall be liable to punishment under the Bharatiya Nyaya Sanhita, 2023 (formerly the Indian Penal Code) or any other law in respect of any agreement made between members of such union for the purpose of furthering any of the objects specified in Section 15, on the ground only that such agreement restrains or is in restraint of trade.¹

The historical necessity behind this provision is not academic. Under the common law of criminal conspiracy inherited from England, any combination by workers to demand higher wages, to withhold labour, or to pressure employers into changing conditions could be prosecuted as a conspiracy in restraint of trade. The English Combination Acts had criminalised worker combinations outright. Section 17 severed that connection for registered Indian trade unions: an agreement between union members that furthers a Section 15 object cannot be attacked as a criminal conspiracy in restraint of trade.

The leading case is R.S. Ruikar v. Emperor (AIR 1935 Nag. 149). The president of the Nagpur Textile Union organised a strike and picketing against a mill. He was convicted of abetment of the offence of molestation under the Criminal Law Amendment Act, 1932. He argued that the Trade Unions Act immunised his actions. The Nagpur High Court’s analysis separated two questions. The immunity in Section 17 applies to the agreement — the combination formed to advance Section 15 objects. It does not extend to substantive criminal offences. The president’s speeches encouraging picketing were one matter; his instruction to his wife to physically beat persons who interfered with her picketing at the mill gate was another. The agreement to strike was within the immunity; individual criminal acts committed in the course of the dispute were not. The section’s own proviso makes this plain: an agreement to commit an offence is not protected.⁹

The practical limit of Section 17 is therefore this: the immunity is for the combination itself — the act of organising, agreeing to act collectively, deciding to strike — when those acts are in furtherance of Section 15 objects. It is not a licence for violence, criminal intimidation, molestation, wrongful restraint, or mischief. A lawful object does not legalise an unlawful method. Peaceful collective action is protected; criminal conduct associated with that action is not.

VI. Civil Immunity Under Section 18

Section 18 is the counterpart of Section 17 in the civil sphere. Section 18(1) provides that no suit or other legal proceeding shall be maintainable in any civil court against a registered trade union or any officer or member thereof in respect of any act done in contemplation or furtherance of a trade dispute to which the union is a party, on the ground only that such act induces some other person to break a contract of employment, or that it is an interference with the trade, business, or employment of some other person, or with the right of any person to dispose of his capital or labour as he wills. Section 18(2) extends equivalent protection against tortious liability.¹

Without this immunity, ordinary civil law would devastate legitimate collective action. A strike that causes production losses interferes with the employer’s business. A boycott that persuades suppliers not to deal with the employer induces breach of commercial contracts. Picketing that dissuades replacement workers interferes with their freedom to work. Each of these is a recognisable civil wrong at common law. Section 18 removes civil liability for them when they are done in contemplation or furtherance of a genuine trade dispute.

The phrase “in contemplation or furtherance of a trade dispute” is the jurisdictional key. A trade dispute is defined in Section 2(j) of the Trade Unions Act as any dispute between employers and workmen, between workmen and workmen, or between employers and employers connected with employment, non-employment, terms of employment, or conditions of labour. The connection between the act and the dispute must be real, not merely asserted.

The Patna High Court examined this nexus in Rohtas Industries Staff Union v. State of Bihar (AIR 1963 Pat. 170). Workers at Rohtas Industries struck in support of disputes over bonus non-payment and non-implementation of an earlier award. The management sought civil compensation for losses caused by the strike. The court held that the employers had no right of civil action against workers participating in a strike, even one held to be illegal under Section 24(1) of the Industrial Disputes Act, because the duty imposed by Sections 22–24 IDA was owed to the public, not to the employer individually. The exclusive remedy for an illegal strike was criminal prosecution under Section 26(1) IDA — not civil damages. The Supreme Court confirmed the broader analysis in Rohtas Industries v. Its Union (AIR 1976 SC 425).¹⁰

The limits of Section 18 are as important as its scope. Violence, fraud, and independent civil or criminal wrongs are not protected. An act committed under cover of a trade dispute but essentially amounting to a tort or crime independent of the dispute does not receive the immunity. Only genuinely industrial action connected to a real trade dispute attracts Section 18’s protection.

VII. Outsiders on the Executive — Section 22

Section 22 of the Trade Unions Act, 1926 provides that not more than one-half of the total number of office-bearers of a registered trade union shall at any one time be persons who are not workmen employed in an industry with which the trade union is connected. The appropriate government may by special or general order exempt a trade union or class of trade unions from this requirement.¹

The provision needs to be read precisely. It does not say that half of office-bearers can be outsiders as a matter of right. It says that no more than half may be outsiders at any one time. At least half must always be actual workers in the relevant industry. The executive of a registered trade union must remain rooted in the industry it represents, even while allowing room for professional organisers, legal advisers, and full-time union workers who may not themselves be employed by any employer within that specific industry.

The reason for permitting any outsiders at all reflects the practical history of the trade union movement in India, where professional organisers, lawyers, and political workers played a significant role in building and running unions, particularly in the early decades after 1926. The provision accommodates that reality while insisting on a worker-majority executive as the non-negotiable baseline.

VIII. The Deeper Structure of the Statute

The Trade Unions Act, 1926 is best understood as a statute with an internal logic that connects every provision to a single underlying purpose: the legal institutionalisation of collective worker action.

The definition in Section 2(h) tells us what qualifies as a union. The registration procedure in Sections 3–13 tells us how that union acquires legal personality and protection. The fund provisions in Sections 15–16 tell us what the union may lawfully do with its resources. The immunity provisions in Sections 17 and 18 tell us how far the union’s collective action is protected from criminal prosecution and civil suit. The executive composition rule in Section 22 tells us who may govern the union. The dissolution provisions in Section 27 and the returns requirement in Section 28 tell us that the union is a regulated legal person, not merely a gathering.

Each of these provisions answers a question that arises naturally from recognising collective worker action as a legal institution. The definition answers: when does a combination become a trade union? Registration answers: when does it become a legal person? The fund provisions answer: how may it use collective resources? The immunities answer: when is collective action protected? Section 22 answers: who may exercise collective authority on its behalf?

That structure also explains why the case law is so important in this area. Courts have had to draw the line between combination and trade union, between industry and sovereign function, between protected collective bargaining and unlawful conduct, and between lawful industrial pressure and civil or criminal liability. The Act provides the framework; the cases give it practical content.

IX. The Practical Takeaways

A trade union under Indian law is defined by its primary purpose — regulating employment relations through collective action — not by the formality of its structure or the size of its membership.

Registration is not compulsory in the sense that a union cannot exist without it. But registration is legally transformative: it gives the union corporate status, property-holding capacity, contractual power, and — most importantly — the statutory immunities that protect its members from criminal conspiracy charges and civil suit for acts done in furtherance of genuine trade disputes.

Section 17 immunises the agreement, not the act. A decision to strike is protected; violence on the picket line is not.

Section 18 immunises acts in contemplation or furtherance of a genuine trade dispute — including inducing breach of employment contracts and interfering with business — but only for registered unions and only where the connection to a real trade dispute is present. Fraud, violence, and independent wrongs are not covered.

Sovereign functions remain a limiting principle. Where the state acts in its core regal capacity — judicial, police, defence, core revenue enforcement — the trade union model does not apply. Where the state runs an industry or commercial undertaking, it does. The post-Bangalore Water Supply position has substantially reduced what counts as a regal function.

Section 22 ensures that a registered union remains rooted in the industry it represents. Not more than half of office-bearers may be outsiders — workers in the relevant industry must always hold the majority of executive positions.

Closing

The Trade Unions Act, 1926 — fewer than thirty sections — encodes a fundamental transformation in the legal treatment of worker organisation. Before it, collective action was conspiracy. After it, collective action became a protected, legally structured institution. The registration procedure is ministerial; the immunities are real and substantial; the limits are equally clear.

What the Act created was not a general immunity for all worker action but a specific, bounded protection for legitimate collective action conducted through registered organisations in the furtherance of genuine trade disputes. The combination that exists primarily to regulate employment relations, that is properly registered, that keeps its funds within Section 15 objects, that maintains the nexus to a genuine trade dispute, and that avoids violence — that combination receives the full protection of the statute. Those who step outside these boundaries find that the Act offers them nothing.

For workers and union office-bearers the message is: register, keep funds within Section 15 objects, maintain the nexus to a genuine trade dispute, and avoid violence. For law students the statute offers a perfect blend of definitional precision, procedural detail, and policy-driven immunities — the combination that makes trade union law one of the most consistently examined topics in the LB-403 paper.
