Among the three great sources of law — legislation, precedent and custom — legislation has become the dominant instrument of legal growth. Salmond memorably contrasts the two: case law is ‘gold in the mine’, a few grains of precious metal buried in a ton of useless matter, while statute law is the ‘coin of the realm’ ready for immediate use. This article maps the analytical anatomy of legislation — the master distinction between supreme and subordinate legislation, the five Salmondian species of subordinate legislation, the constitutional law of delegated and conditional legislation as worked out by the Indian Supreme Court, and finally the theory of codification championed by Bentham. Every section number and case citation below has been independently verified.
Legislation as a Source of Law
Legislation, in jurisprudence, means the laying down of legal rules by a competent authority — Parliament, a State legislature or some body to which law-making power has been entrusted. The term derives from legis (law) and latum (to make or set down). In its widest sense it covers every method by which law comes into being; in its strict, modern sense it denotes the deliberate creation of legal rules in written form, called statute law or enacted law.
For the purposes of jurisprudence, Salmond divides the origins of law into legal sources and historical sources. Legal sources are authoritative — recognised as of right by the courts and directly productive of new law; statutes and authoritative precedents fall here. Historical sources operate only indirectly and have no claim as of right in the courts. Legislation is the paradigm legal source: the courts must recognise and apply an enactment as law, whatever their view of its wisdom. For the broader frame of how law is generated, see our companion note on the analytical and imperative school, which treats law as the command of the sovereign.
Why Legislation is Superior to Precedent
Salmond and Bentham both rank legislation above precedent as an instrument of legal growth, and the reasons are worth memorising for the exam.
(i) Abrogative and reformative power. Legislation can both make new law and abolish old law. A precedent, by contrast, has constitutive but not abrogative efficacy — it can produce good law, but once stated its operation is, in the older view, irreversible. Legislation can therefore reform the law deliberately; precedent must wait for a litigant.
(ii) Division of labour and efficiency. The legislature makes the law, the executive operates it, and the judiciary interprets and applies it. This separation produces efficiency that the judge, who must both find and apply law in a single act, cannot match.
(iii) Prospective operation. A statute declares the law before the act to which it applies, satisfying natural justice — the citizen knows the rule before it is enforced. A judicial precedent, as in Rylands v. Fletcher, creates and declares the law in the very act of applying it to past conduct, so it operates retrospectively.
(iv) Law of the future. Legislation can provide for circumstances not yet arisen and can fill gaps the moment a doubt is noticed; a court must wait for definite facts to come before it, so a bad precedent endures until a fresh case allows its overruling.
(v) Superiority of form. Statute law is brief, clear, accessible and authoritative; case law lies buried in the vast records of litigation. This is the point of Salmond’s ‘coin of the realm’ metaphor. The trade-off is rigidity: statute is fixed, whereas case law retains flexibility and an appeal to reason and justice. The relative virtues of precedent are explored in our note on the historical school of Savigny and Maine, which mistrusts hasty legislation.
Supreme Legislation
Salmond’s master classification divides all legislation into two classes: supreme and subordinate. Supreme legislation is that which proceeds from the sovereign or supreme power in the State and which, in consequence, cannot be repealed, annulled or controlled by any other legislative authority. It is the highest expression of law-making will in the polity.
The classic English illustration is the legislation of the British Parliament, which, on the orthodox Diceyan view of parliamentary sovereignty, can make or unmake any law whatever and is subject to no legal limit. In India the position is more nuanced: Parliament and the State legislatures are supreme within their allotted spheres under the Seventh Schedule, but their legislation is itself controlled by a higher norm — the Constitution — and is subject to judicial review for constitutionality. In a strict Austinian sense, therefore, the truly supreme legislation in India is the constituent power that produces and amends the Constitution. The link between sovereignty and command is the central theme of the analytical imperative school.
The practical significance of the label ‘supreme’ lies in what it excludes. Supreme legislation is immune from the doctrine of ultra vires: a court cannot strike down an Act of a supreme legislature on the ground that it travels beyond conferred power, because no power was conferred — the authority is original and plenary. The only checks are political and, in a constitutional democracy, the entrenched limits of the Constitution itself. This is why, in India, an enactment of Parliament can be invalidated for violating fundamental rights or the basic structure but never for being ‘in excess of delegated authority’, a vice that attaches only to subordinate legislation. The whole apparatus of rule-control examined later in this article presupposes that we are dealing with subordinate, not supreme, law.
Subordinate Legislation: the Five Salmondian Kinds
Subordinate legislation is legislation that proceeds from any authority other than the sovereign power and is therefore dependent for its continued existence and validity on a superior or supreme authority. Salmond identifies five species.
(1) Colonial legislation. The legislatures of colonies and dominions of the British Empire historically possessed delegated law-making power, but their enactments were subordinate to and could be repealed by the Imperial Parliament. Today these have largely matured into independent supreme legislatures.
(2) Executive legislation. Where the legislature delegates rule-making power to the executive, the resulting rules, regulations and orders are subordinate legislation — the most important modern category, treated separately below as delegated legislation.
(3) Judicial legislation. Superior courts are often empowered to frame rules regulating their own procedure — for example, the rule-making power of the Supreme Court and High Courts in India. Such rules, though made by the judiciary, are genuinely legislative in character.
(4) Municipal legislation. Municipal and other local authorities are given limited power to make bye-laws for their areas. These bind within the locality but remain subordinate to the parent statute.
(5) Autonomous legislation. The State sometimes recognises the power of private bodies — universities, registered companies, railway undertakings — to make bye-laws and regulations for their members or operations, which the courts will enforce. This is autonomic legislation.
A point of analytical interest is that all five kinds share a single defining feature: their validity is derivative. Each owes its legal force to a superior norm — the parent statute or constitution — and each can be annulled or overridden by the authority above it. This is what justifies grouping such diverse phenomena as a colonial enactment, a ministerial rule, a High Court procedural rule, a municipal bye-law and a university regulation under the single head of subordinate legislation. The modern explosion of executive legislation has so far outstripped the others that ‘subordinate legislation’ and ‘delegated legislation’ are now often used interchangeably, though strictly the former is the genus and the latter only its most important species.
Delegated Legislation and its Necessity
Delegated legislation — the most significant form of executive subordinate legislation — arises when the legislature, by the parent or enabling Act, confers on the executive the power to make rules, regulations, notifications and orders within the policy laid down by the statute. It has grown enormous in the modern administrative State for practical reasons: pressure on legislative time, technical complexity, the need for flexibility and rapid amendment, the handling of emergencies, and the impossibility of foreseeing every detail in advance.
The constitutional anxiety is that excessive delegation amounts to an abdication of the legislative function. The leading Indian authority is the advisory opinion In re The Delhi Laws Act, 1912, AIR 1951 SC 332, where a seven-judge bench, by a celebrated diversity of reasoning, settled the foundational principle: the legislature may delegate ancillary and incidental functions, but it cannot delegate its essential legislative function — that is, the laying down of legislative policy and its formulation as a binding rule of conduct. The legislature must itself enact the policy and the standard; only the working out of details may be entrusted to the executive.
The Permissible Limits: Policy and Guidelines
The principle of In re Delhi Laws Act was applied and refined in a line of cases. In Harishankar Bagla v. State of Madhya Pradesh, AIR 1954 SC 465, the appellants were prosecuted under the Essential Supplies (Temporary Powers) Act, 1946 for moving cotton cloth without a permit and challenged Sections 3, 4 and 6 as excessive delegation. The Supreme Court upheld the Act, holding that since the legislature had itself declared the policy — maintaining and increasing supplies of essential commodities and securing their equitable distribution and availability at fair prices — and had furnished sufficient guidance in Section 3, the conferment of rule-making power was a valid delegation and not abdication.
The doctrine of excessive delegation was crystallised in Gwalior Rayon Silk Manufacturing (Wvg.) Co. Ltd. v. Assistant Commissioner of Sales Tax, AIR 1974 SC 1660. The challenge was to Section 8(2)(b) of the Central Sales Tax Act, 1956, which fixed the inter-State tax rate by reference to the local rate set by each State legislature. Upholding the provision, the Court reiterated that a legislature must not efface itself or abdicate its essential function, but that adopting an ascertainable external standard is not abdication where the policy remains the legislature’s own. The rule that emerges is consistent throughout: delegation is valid only where the parent Act discloses a legislative policy and lays down standards or guidelines to control the delegate’s discretion.
Conditional Legislation Distinguished
Conditional legislation must be carefully distinguished from delegated legislation. In conditional legislation the legislature itself makes the complete law, leaving to the executive only the determination of the condition, time, place or area upon which the law is to come into operation. No law-making power is transferred — the executive merely supplies the fact on which the statute’s own command springs into force.
The fountainhead is the Privy Council’s decision in Queen v. Burah (1878) LR 5 IA 178, concerning an Act that removed the Garo Hills from ordinary courts and empowered the Lieutenant-Governor to fix the date and extend its application to neighbouring tracts. The Privy Council held this to be valid conditional legislation, not an unlawful delegation: the Indian legislature had enacted a complete law and had merely entrusted the executive with the discretion to bring it into operation. It famously affirmed that the Indian legislature was a sovereign law-making body within its sphere, neither an agent nor a delegate of the Imperial Parliament.
The boundary between modifying details and changing policy was drawn in Rajnarain Singh v. Chairman, Patna Administration Committee, AIR 1954 SC 569. The Court held that an executive authority may be authorised to apply, with modifications, an existing or future law, but only so long as it makes no change in any essential feature — and an essential feature certainly includes a change of policy. Selecting and modifying provisions for application is permissible; altering the policy of the Act considered as a whole is not.
Controls Over Delegated Legislation
Because subordinate legislation derives its life from the parent statute, it is subject to controls that supreme legislation is not. These fall into three heads.
Judicial control operates through the doctrine of ultra vires. Substantive ultra vires strikes down a rule that exceeds the powers conferred by the enabling Act or offends the Constitution. Procedural ultra vires invalidates a rule made without observing a mandatory procedure prescribed by the parent Act — such as prior consultation or publication. Delegated legislation may also be tested for unreasonableness and for conflict with other statutes.
Parliamentary control is exercised through the laying of rules before the House, affirmative and negative resolution procedures, and scrutiny by Committees on Subordinate Legislation. Procedural control includes requirements of antecedent publicity, consultation of affected interests, and publication in the official gazette as a condition of validity. The analytical reduction of all rules to the will of a superior authority echoes the command theory examined in the overview of the schools of jurisprudence.
Interpreting Enacted Law: the Mischief Rule
Because statute law is rigid and authoritative, the courts’ primary duty is to interpret it. The most purposive of the canons of construction is the mischief rule, enunciated by the Barons of the Exchequer in Heydon’s Case (1584) 76 ER 637. It directs the court to consider four matters: (1) what was the common law before the Act; (2) what was the mischief and defect for which the common law did not provide; (3) what remedy Parliament has resolved and appointed to cure the mischief; and (4) the true reason of the remedy. The judge must then so construe the statute as to suppress the mischief and advance the remedy.
The classic modern application is Smith v. Hughes [1960] 1 WLR 830. Prostitutes solicited passers-by from balconies and windows after the Street Offences Act 1959 made it an offence to solicit ‘in a street’. Lord Parker CJ, applying the mischief rule, held that since the mischief aimed at was the harassment of people walking in the street, soliciting from a balcony fell within the Act; the women were convicted. The place from which the solicitation came was immaterial because the object of the statute was to clean up the streets. The rule thus lets the courts give ‘force and life’ to the true intention of Parliament.
Codification: Meaning and Kinds
Codification is the systematic reduction of the whole body of law on a given subject — whether previously contained in statutes, precedents or custom — into a single, coherent, authoritative written code. The word ‘code’ means a book of laws, and the term ‘codification’ was coined by Jeremy Bentham, who used it in correspondence around 1815 and made the codifying of law the great project of his utilitarian jurisprudence. Bentham wished to abolish judge-made common law so that all law would emanate from the legislator in a form so clear that every citizen could know it.
Jurists distinguish three kinds of code by reference to their source-material. A creative code makes new law on a subject not previously regulated. A consolidating code gathers existing statutory and case law on a subject into one orderly enactment without changing its substance. A codifying code (codification proper) restates the entire law on a subject — statute, precedent and custom alike — in a comprehensive form. Indian examples illustrate the technique: the Indian Penal Code, 1860 and the Indian Contract Act, 1872 are largely creative-cum-codifying, while many later consolidating Acts merely tidy scattered provisions.
Codification should not be confused with mere consolidation in ordinary usage. Consolidation re-enacts existing statute law without altering its substance, whereas codification proper absorbs the unwritten law — precedent and custom — and gives it statutory form, often changing and clarifying it in the process. A codifying statute therefore tends to supersede the earlier case law on its subject, so that, as the House of Lords observed of the English Sale of Goods Act, the first task of the interpreter is to read the code as it stands rather than to hunt through the pre-code decisions, resorting to them only where the code is ambiguous. This makes codification a powerful but irreversible step: once the law is codified, its future development passes from the judge back to the legislature.
Merits and Demerits of Codification
The advantages of codification follow from the virtues of legislation generally. A code brings certainty: the law is reduced to a fixed, knowable text, reducing arbitrariness and advancing the rule of law. It brings clarity and accessibility: scattered rules are collected, logically arranged and made intelligible to citizen and lawyer alike. It brings uniformity and unity, replacing a patchwork of local customs and conflicting precedents with a single regime — a powerful instrument of national integration. It is also systematic and planned, allowing the law to be reformed coherently rather than piecemeal.
The disadvantages are those that Savigny and the historical school pressed against premature codification. A code tends to rigidity: once enacted it resists organic growth and may freeze the law at the moment of drafting. It risks incompleteness, for no draftsman can foresee every case, leaving gaps that courts must fill. Its very generality can produce injustice in the hard case, and it may suppress the spontaneous evolution of law through custom and judicial reasoning. Savigny’s objection — that law is the organic expression of the Volksgeist and cannot be successfully imposed by deliberate codification before the nation is ripe for it — is set out fully in our note on the historical school.
Exam Synthesis and Comparative Table
For judiciary and CLAT-PG answers, organise the topic around four contrasts. First, supreme versus subordinate legislation: supreme proceeds from the sovereign and is uncontrollable; subordinate proceeds from a delegate and is subject to ultra vires review — remember the five kinds (colonial, executive, judicial, municipal, autonomous). Second, delegated versus conditional legislation: in delegated legislation the executive makes rules within a policy; in conditional legislation the legislature makes the whole law and the executive only determines when or where it operates — the distinction of Queen v. Burah. Third, the permissible limits of delegation: In re Delhi Laws Act, Harishankar Bagla and Gwalior Rayon together hold that essential legislative policy may not be delegated and guidelines must be furnished. Fourth, codification: a Benthamite project prizing certainty, resisted by Savigny’s historicism. For the wider context of legislation as one of three sources of law, return to the Jurisprudence notes hub, and review the rival emphasis on custom and spontaneous law in the historical school and the policy-driven view of the sociological school.
Frequently asked questions
What is the difference between supreme and subordinate legislation?
Supreme legislation proceeds from the sovereign or supreme power in the State and cannot be repealed, controlled or annulled by any other authority — the British Parliament is the classic example. Subordinate legislation proceeds from some authority other than the sovereign, depends on a superior authority for its validity, and is subject to ultra vires review. Salmond lists five kinds: colonial, executive, judicial, municipal and autonomous (autonomic) legislation.
What is the difference between delegated and conditional legislation?
In delegated legislation the legislature confers genuine rule-making power on the executive to fill in details within a policy it has laid down. In conditional legislation the legislature itself enacts the complete law and leaves to the executive only the determination of the condition, time or area on which the law will take effect — no law-making power is transferred. The Privy Council in Queen v. Burah (1878) drew this line, upholding the Lieutenant-Governor's power merely to bring a complete Act into operation.
What did In re Delhi Laws Act, 1912 decide about delegation?
In In re The Delhi Laws Act, 1912, AIR 1951 SC 332, a seven-judge bench held that the legislature may delegate ancillary and incidental functions but cannot delegate its essential legislative function — the laying down of legislative policy and its formulation as a binding rule. This case is the foundation of the Indian doctrine of permissible delegation and the prohibition on legislative abdication.
What is the doctrine of excessive delegation?
The doctrine, crystallised in Gwalior Rayon Silk Mfg. Co. v. Assistant Commissioner of Sales Tax, AIR 1974 SC 1660, holds that a legislature must not abdicate or efface itself by transferring its essential function. Delegation is valid only where the parent Act discloses a legislative policy and lays down standards or guidelines that control the delegate's discretion. In Harishankar Bagla v. State of M.P., AIR 1954 SC 465, delegation under the Essential Supplies Act was upheld because the policy and guidance were present in the statute.
What is the mischief rule and which cases illustrate it?
The mischief rule, laid down in Heydon's Case (1584) 76 ER 637, directs a court to ask what the common law was before the Act, what mischief it failed to remedy, what remedy Parliament appointed, and the true reason of the remedy — then to construe the statute so as to suppress the mischief and advance the remedy. In Smith v. Hughes [1960] 1 WLR 830, soliciting from a balcony was held to fall within 'in a street' under the Street Offences Act 1959 because the mischief aimed at was the harassment of passers-by.
What is codification and who championed it?
Codification is the systematic reduction of the whole law on a subject — statute, precedent and custom — into a single authoritative written code. The term was coined by Jeremy Bentham, who made codification central to his utilitarian jurisprudence, hoping to abolish judge-made law so that all law would flow clearly from the legislator. Codes may be creative, consolidating or codifying. Its merits are certainty, clarity and uniformity; its demerits, urged by Savigny and the historical school, are rigidity and incompleteness.
