Delegated Legislation — Need, Constitutionality, Limits

Delegated legislation is the largest single source of operating law in modern India — by volume, the rules, regulations, and notifications made by the executive under empowering statutes far exceed the primary legislation passed by Parliament and the State Legislatures combined. The constitutional question that haunts the practice is the question of limits: where does permissible delegation end and unconstitutional abdication of legislative function begin? This chapter sets out the need for delegated legislation, the doctrine that establishes its constitutionality, and the limits the Indian courts have imposed on it. The presiding authority is the Supreme Court's decision in In re Delhi Laws Act (AIR 1951 SC 332), often called the bible of Indian delegated legislation.

The frame of the discussion is set by the constitutional architecture explored in earlier chapters. The doctrine of administrative law proceeds from the constitutional commitment to the rule of law and the separation of powers. Delegated legislation sits inside that architecture: the legislature cannot delegate everything, because that would amount to abdication; but it must be permitted to delegate something, because the welfare State could not function without the practice. The work of doctrine is to draw the line.

What delegated legislation is

Delegated legislation, also called subordinate legislation, refers to all law-making that takes place outside the legislature itself. It is generally expressed as rules, regulations, orders, bye-laws, directions, schemes, notifications, and similar instruments. The Constitution itself recognises delegated legislation: Article 13(3) defines "law" as including any ordinance, order, bye-law, rule, regulation, notification, custom, or usage having in the territory of India the force of law.

The terminology matters. "Delegated" emphasises that the rule-making authority derives its power from a delegating Act — the empowering statute. "Subordinate" emphasises that the resulting legislation is subordinate to the parent Act and cannot operate beyond its limits. The two terms are used interchangeably in Indian usage. Both are distinct from "executive legislation" in the strict sense — the ordinance-making power of the President under Article 123 and of the Governor under Article 213, which is a constitutional power exercised in its own right and not under any empowering statute.

The need for delegated legislation

The case for delegated legislation rests on five practical necessities of modern government.

Compulsive necessity. Even if Parliament sat 365 days a year and 24 hours a day, it could not produce the volume of detailed law required for the proper functioning of a welfare and service State. The welfare State licenses, regulates, taxes, allocates, inspects, and adjudicates across hundreds of subject-matters; only a fraction of that detail can be settled in primary legislation.

Technical know-how. Legislators are generalists. The detailed specifications required for, say, drug-safety regulations, telecommunications standards, or pollution control are technical matters on which the empowering Ministry, working with expert advisers, is better placed to legislate than Parliament itself.

Flexibility and experimentation. A statute, once passed, must remain in force until the next session in which it can be amended. In areas of rapid change — financial markets, technology regulation, public health responses — that is too slow. Delegated legislation permits constant adaptation to changing circumstances and the use of accumulated administrative experience.

Emergency action. A modern society faces occasions — outbreaks of communicable disease, financial-system stress, breakdowns of law and order — when there is a sudden need for legislative action. The legislature cannot meet at short notice; the executive must therefore have stand-by powers exercisable through subordinate legislation.

Discretion in welfare administration. Where government action involves the exercise of discretion in welfare administration — the expansion of public utility services, the allocation of public resources to changing needs — administrative rule-making is the only viable method.

The Supreme Court has repeatedly recognised these necessities. In St. John's Teachers Training Institute v. Regional Director, NCTE (AIR 2003 SC 1533), the Court observed that delegated legislation is "framed with care and minuteness" by the statutory authority, which is in a better position to adapt the Act to special circumstances and to consult interests affected by its practical operation. The earlier antipathy towards delegated legislation — once criticised as undemocratic and an extension of bureaucratic power — has, in modern practice, given way to acceptance of its administrative inevitability.

Types of delegated legislation

The case law has identified several types of delegated legislation, each with its own constitutional limits.

1. Enabling Act provisions. Power to bring an Act into operation. The rule-making is preparatory: the executive determines the date or manner in which the Act takes effect.
2. Extension and application provisions. Power to extend an Act to a territory, with such restrictions and alterations as the executive thinks fit, or for a specified duration, or to specified persons.
3. Dispensing and suspending provisions. Power to grant exemptions from any provision of the Act in particular cases or classes of cases (subject to Article 14), or to suspend the operation of any Act.
4. Alteration provisions. Power to alter or amend the parent Act — most commonly the power to alter the Schedule to bring in new items ejusdem generis with the existing items.
5. Supplementary provisions. Power to elaborate, supplement, or work out the principles laid down in the Act — the classical power to fill in details.
6. Taxing provisions. Power to levy or vary taxes within limits set by the Act, provided the policy of the taxing statute has been laid down.
7. Exceptional delegation — the Henry VIII clause. Wide powers to amend or repeal the parent Act, named after the British monarch noted for absolute despotism. Treated with the greatest doctrinal suspicion. Discussed in detail in the chapter on exceptional delegation.
8. Sub-delegated legislation. Where the rule-making authority delegates the power further to a subordinate authority — discussed at length in the same chapter.

The constitutional question — In re Delhi Laws Act

The constitutionality of delegated legislation in India was settled, in its broad outlines, by the Supreme Court's decision in In re Delhi Laws Act (AIR 1951 SC 332). The case is the doctrinal anchor of the field and is referred to as the bible of Indian delegated-legislation jurisprudence. Every later doctrine on permissible delegation, on the operation of the policy-and-guidelines test, and on the line drawn by judicial control over delegated legislation traces its lineage back to it.

The reference

The President referred three questions to the Court under Article 143 concerning the validity of three different statutes: the Delhi Laws Act, 1912, the Ajmer-Merwara (Extension of Laws) Act, 1947, and the Part C States (Laws) Act, 1950. Each conferred power on the executive to extend, with alterations, laws in force in another part of the country to the Part C States (today's Union Territories), and the Part C States (Laws) Act 1950 went further by also authorising the executive to repeal or amend any corresponding existing law in the territory to which the extended law was applied.

The seven judgments

Before turning to the judgments, it helps to recall the constitutional setting. The Indian framers, having rejected the rigid American model in favour of a Westminster-style scheme (set out in the chapter on separation of powers in Indian administration), nonetheless retained a written constitution and judicial review. Re Delhi Laws was therefore the first major test of how delegation would operate in this hybrid setting.

Seven judges sat on the case (Fazal Ali, Patanjali Sastri, Mahajan, Mukherjee, Das, and Bose JJ., with the Chief Justice). The judgments, while diverse in reasoning, agreed on two propositions:

Delegation is constitutionally permissible. Parliament must delegate — the multitudinous problems of modern governance cannot be addressed without it.

Delegation is constitutionally limited. Because the Indian legislature is a creature of a written Constitution (unlike the British Parliament, which operates under an unwritten constitution), it cannot enjoy unlimited freedom to delegate. The limit is fixed by the doctrine that the legislature must retain its essential legislative function.

The essential-legislative-function test

The "essential legislative function" was identified as the formulation of policy and its enactment into a binding rule of conduct. The legislature must declare the policy, lay down the standard, and embody it in the statute. The work that may be delegated is the work of subordinate legislation — the filling in of details, the working out of administrative machinery, the calibration of rules to local conditions. As Mukherjee J. put it: the work of law-making must be done primarily by the authority on which the duty is constitutionally entrusted, and the legislature cannot throw that responsibility on the shoulders of an agent or delegate.

The decision drew the operative line:

• The power to extend and apply a law to a new area, with alterations confined to local adjustments not involving any radical change of policy, was upheld.
• The power to alter a law in matters of detail, subject to the same restriction, was upheld.
• The power to amend or repeal existing laws in the area, however, was struck down — that involved a determination of legislative policy and could not be delegated.

By a 4:3 majority, the Court held that the second part of Section 2 of the Part C States (Laws) Act 1950 — the part authorising the executive to repeal or amend corresponding provincial law — was unconstitutional. By a 5:2 majority, the first part (extension with alteration) was upheld.

What is an essential legislative function?

The doctrine that emerged from Re Delhi Laws required courts in subsequent cases to identify, in particular contexts, what counts as an essential legislative function and what counts as merely subordinate detail. Several lines of decision developed.

Permissible categories of delegation

Five categories of delegation have been routinely upheld in the post-Re Delhi Laws case law: skeleton legislation with policy in the parent Act; powers of inclusion and exclusion; powers of alteration confined to local conditions; powers to remove difficulties consistent with the parent Act; and limited taxing powers within stated maxima and minima. Each is treated below.

Power to supply details — skeleton legislation

Where the parent Act sets out the policy clearly, very wide rule-making power can be conferred to fill in details. In Bagla v. State of M.P. (AIR 1954 SC 465), Section 3 of the Essential Supplies Act, 1946 — empowering the Government to regulate production and supply of essential goods so far as it appeared necessary for maintaining or increasing supplies or securing equitable distribution — was upheld. The provision was treated as supplying sufficient guidance for skeletal legislation. Garewal v. State of Punjab (AIR 1959 SC 512) similarly upheld broad rule-making power on conditions of service in the All India Services.

Power of inclusion and exclusion

Statutes commonly authorise the executive to bring particular persons, bodies, or goods within the scope of a regulatory regime, or to exempt them. In Edward Mills v. State of Ajmer (AIR 1955 SC 25), the empowering Act authorised the executive to fix minimum wages for industries in the Schedule and to add new industries by notification. The Court upheld the delegation: the policy — to fix minimum wages and prevent exploitation — was on the face of the Act, and the addition of industries was a matter of administrative judgment within that policy.

Power of alteration

The power to alter the parent Act is more troublesome. In Raj Narain v. Chairman, Patna Administration Committee (AIR 1954 SC 569), the State had been empowered to extend any section of the Bihar and Orissa Municipal Act to a particular area "subject to such restriction and alterations as it may think fit." The State picked out a tax-levying section, altered it to dispense with the procedural requirement of hearing objections, and applied it to Patna town. The Court struck down the action: the alteration altered the policy of the Act (which was to give inhabitants a chance of being heard before tax imposition), and policy alteration is essential legislative function that cannot be delegated.

Power to remove difficulty — Henry VIII clauses

Power to make provisions to "remove difficulties" in giving effect to the Act has been treated with care. In Jalan Trading Co. v. Mill Mazdoor Union (AIR 1967 SC 691), Section 37(1) of the Payment of Bonus Act, 1965 authorised the Government to make provisions to remove difficulties or doubts, and Section 37(2) made the Government's order final. The Court held the provision ultra vires: it authorised the Government to determine for itself what the purposes of the Act were — an exercise of essential legislative power that could not be delegated. By contrast, in Gammon India Ltd. v. Union of India (AIR 1974 SC 960), Section 34 of the Contract Labour Act, 1970 — authorising removal of difficulties consistent with the provisions of the Act and not contemplating any alteration of the Act itself — was upheld.

Power to impose tax

Taxation is, in democratic theory, the sole prerogative of the legislature. But modern practice has accepted limited delegation of taxing power. In Devi Das v. State of Punjab (AIR 1967 SC 1895), the delegation of power to fix the tax rate between a maximum and minimum laid down in the Act was upheld. In Delhi Municipal Corporation v. Birla Cotton Mills (AIR 1968 SC 1232), delegation to a municipal corporation of power to impose electricity tax without a maximum was upheld on the ground that the corporation is itself a representative body. The general principle, set out in Darshan Lal Mehra v. Union of India (AIR 1992 SC 1848), is that wide expressions like "for the purposes of the Act" can supply sufficient guidelines when the power is delegated to a representative authority such as a municipality.

The abdication test and its limits

Justice K.K. Mathew, in Gwalior Rayon Mills v. Asst. Commr. Sales-tax (AIR 1974 SC 1660), proposed a different test: so long as the legislature retained the power to repeal the empowering Act, it had not abdicated its function, and the delegation must be considered valid however broad. The majority in Gwalior Rayon, led by Justice Khanna, did not accept the abdication test and reaffirmed the established policy-and-guidelines test. The mainstream Indian doctrine therefore continues to operate on the policy-and-guidelines test, with the abdication test remaining a minority position.

The working line — permissible vs impermissible delegation

The case law since Re Delhi Laws can be summarised in five propositions:

1. The legislature must declare the policy of the Act and lay down the standard, expressly or by necessary implication. The policy can be gathered from the history, the preamble, the title, the scheme of the Act, or the statement of objects and reasons.
2. Within that policy, the legislature can delegate the working out of details — the form of subordinate legislation called conditional legislation sits at the more permissible end of this spectrum.
3. The doctrine of natural justice applies to the application of delegated legislation in particular cases, even where the rule-making itself is not subject to a hearing.
4. The chapter on judicial review of administrative action sets out the doctrinal grounds on which delegated legislation can be challenged.
5. Power to alter the parent Act is permissible only to the extent that the alteration does not change the policy of the Act.
6. Power to repeal an existing law cannot be delegated — that is essential legislative function.
7. The doctrines of parliamentary control and judicial control together ensure that delegated legislation, once made, remains within the limits of the empowering Act and the Constitution.

Comparative position — England, the United States, India

The Indian doctrine sits between the English and the American positions, and locating it on that spectrum is part of what answers expect candidates to do.

England. The Westminster Parliament is sovereign. There is no written constitution that limits its capacity to delegate, and the courts cannot strike down a statute on the ground that the delegation is too broad. The English position is therefore one of unlimited delegation as a matter of constitutional law. The control on delegated legislation in England is parliamentary and political rather than judicial — laying procedure, scrutiny committees, and the threat of repeal.

The United States. The American Constitution embodies a stricter doctrine. The Supreme Court has, since the New Deal era, accepted broad delegation provided Congress lays down an "intelligible principle" — a relaxed version of the older non-delegation doctrine. The doctrine has rarely been used to strike down legislation in recent decades, but it remains alive in principle. The American position is therefore one of limited delegation tempered by deferential judicial review.

India. The Indian Constitution is written but does not contain an express prohibition on delegation. The Supreme Court in Re Delhi Laws chose the American model in preference to the English: delegation is constitutionally limited and subject to the policy-and-guidelines test, but the test is applied with substantial deference, particularly in technical and welfare fields. The Indian position is therefore one of generous delegation tempered by the residual essential-legislative-function doctrine and by the basic-structure status of the rule of law.

Recent developments

The doctrine of delegated legislation continues to evolve.

Reservation jurisprudence. In Ashoka Kumar Thakur v. Union of India (2008) 6 SCC 1, the Central Educational Institutions (Reservation in Admission) Act, 2006 delegated to the Union Government the power to determine who would constitute "Other Backward Class". The challenge on the ground of excessive delegation was repelled — the Court held that there were sufficient guidelines for determining backward classes drawn from the constitutional architecture of Articles 15 and 16, the National Commission for Backward Classes Act, and the Mandal Commission framework.

Repeal limits reaffirmed. In Vasu Dev Singh v. Union of India (2006) 12 SCC 753, the Court reaffirmed that the legislature cannot delegate the power to repeal a law or to alter its essential features. The principle laid down in Re Delhi Laws on this point continues to be the controlling rule.

Policy-and-guidelines test reaffirmed. In J.K. Industries Ltd. v. Union of India (2007) 13 SCC 673, the Court repeated that delegation is valid only when it is confined to legislative policy and guidelines. The test has therefore been the controlling standard for over seventy years and has resisted the abdication-test challenge.

Subordinate-legislation accountability. The post-RTI period has produced a more demanding climate for delegated legislation. Empowering Acts now commonly require pre-publication of draft rules, public consultation, and ex post review. The Lok Sabha Subordinate Legislation Committee and the corresponding committee of the Rajya Sabha continue to scrutinise rules, and judicial review under Article 226 remains available against rules that exceed the empowering Act or violate the Constitution. The combination of statutory consultation, parliamentary scrutiny, and judicial review now constitutes the working framework of accountability.

Practical takeaways for the exam

Three propositions to fix in memory. First, delegated legislation is constitutionally necessary and constitutionally limited — the Indian doctrine, fixed by Re Delhi Laws, requires the legislature to retain its essential function while permitting wide delegation of detail. Second, the test for validity is the policy-and-guidelines test: the parent Act must declare the policy and lay down the standard; the delegated legislation must operate within them. Third, certain functions cannot be delegated at all — the power to repeal existing law, the power to alter the policy of the parent Act, and the power to determine for the executive itself what the purposes of the Act are.

The aspirant who has internalised Re Delhi Laws and the policy-and-guidelines test has the analytical tools to address any delegation question on the paper. The chapters that follow build directly on this foundation: the narrower category of conditional rule-making is one species of permissible delegation; sub-delegation and Henry VIII clauses are the most contentious species; parliamentary and judicial controls are the mechanisms by which the limits are enforced.

Frequently asked questions

Why is delegated legislation constitutionally necessary?

Five reasons. The volume and technical complexity of modern legislation exceed what any legislature can produce in primary form. Legislators are generalists; technical regulation requires expert detail. Statutes are slow to amend; rapidly changing fields (finance, technology, public health) need flexible rule-making. Emergencies require stand-by powers exercisable without convening the legislature. And welfare administration involves discretionary calibration to changing local needs. The Supreme Court in St. John's Teachers Training Institute v. Regional Director, NCTE (2003) recognised these necessities and treated delegated legislation as the natural reflection of changes in our ideas of government in the modern era.

What is the leading authority on the constitutionality of delegated legislation in India?

In re Delhi Laws Act (AIR 1951 SC 332). The Supreme Court, sitting as seven judges, decided the question in seven separate but converging judgments. The majority held that delegation is constitutionally permissible but constitutionally limited: the legislature must retain its essential legislative function — the formulation of policy and its enactment into a binding rule. The detail can be delegated; the policy cannot. The decision is described as the bible of Indian delegated-legislation jurisprudence and supplies the doctrinal foundation for every subsequent case.

What is an 'essential legislative function' that cannot be delegated?

An essential legislative function consists in declaring the policy of the law and laying down the standard which is to be enacted into a binding rule of conduct. The legislature must do this itself — through the empowering Act, with the policy expressly or impliedly stated and the standard sufficiently clear to guide the delegate. The case law has identified several functions as essential and non-delegable: the power to repeal an existing law (Re Delhi Laws), the power to alter the policy of the parent Act (Raj Narain), the power to determine for the executive itself what the purposes of the Act are (Jalan Trading).

Can the legislature delegate the power to impose tax?

Yes, within limits. Although taxation is in democratic theory the sole prerogative of the legislature, the case law has accepted limited delegation. The legislature must lay down the policy — what is to be taxed, who is to pay, and the broad standards. Within that policy, it may delegate the determination of rates between specified maxima and minima (Devi Das v. State of Punjab, AIR 1967 SC 1895), the power to include or exempt particular items, and (in the case of representative bodies like municipalities) the determination of rates without an upper limit. The phrase 'for the purposes of the Act' has been treated as a sufficient guideline in some cases (Darshan Lal Mehra v. Union of India, AIR 1992 SC 1848).

What is the abdication test and why does it not represent the mainstream Indian doctrine?

The abdication test was proposed by Justice K.K. Mathew in Gwalior Rayon Mills v. Asst. Commr. Sales-tax (AIR 1974 SC 1660): so long as the legislature retains the power to repeal the empowering Act, it has not abdicated its function and the delegation is valid however broad. The majority in Gwalior Rayon, led by Justice Khanna, rejected this test and reaffirmed the established policy-and-guidelines test, under which the legislature must lay down policy and standards in the empowering Act itself. The mainstream Indian doctrine therefore continues to operate on the policy-and-guidelines test; the abdication test remains a minority position cited occasionally but not generally followed.
