Administrative Law and Constitutional Law Compared: Separate Subjects, Common Foundations and an Indistinct Boundary

Constitutional law is concerned with the structure of the State, the distribution of power among its organs and the rights the individual holds against it. Administrative law is concerned with the exercise of power by the bodies that carry on the day-to-day work of government. Stated that way the subjects look distinct, and in a system with a written constitution they largely are. In India the boundary is far less clear, because the grounds on which administrative action is reviewed are constitutional grounds, the remedies are constitutional remedies, and the jurisdiction to grant them is part of the basic structure. The older comparison, drawn from countries without written constitutions, therefore needs qualification here. This topic sets out the comparison and where it breaks down.

1. The Comparison

Basis	Constitutional law	Administrative law
Subject matter	The structure of the State and the distribution of its powers	The exercise of power by administrative authorities
Concerned with	Organs of government in repose, and the rights of the individual	Government in motion, and the machinery of administration
Source	The Constitution itself	Statutes, rules, precedent and constitutional principle
Typical question	Is the law within the competence of the legislature and consistent with Part III?	Did the authority act within its power, fairly and on relevant considerations?
Field	Legislature, executive, judiciary, federalism, fundamental rights	Discretion, delegated legislation, natural justice, tribunals, liability
Remedies	Declarations of invalidity, writs, compensation for breach of rights	Writs, appeals, tribunals, damages, statutory remedies
Relation	The genus	A species, which has outgrown the classification
Amendability	Alterable only by constitutional amendment	Alterable by ordinary legislation, subject to the Constitution

The older writers treated administrative law as a branch of constitutional law, on the footing that both deal with the organs of government and that the distinction is one of emphasis: constitutional law describes the organs at rest and administrative law describes them in motion. That account remains useful, but it understates how far administrative law now has its own doctrines, its own literature and its own remedies.

2. The Constitutional Foundation of Review

📖 Minerva Mills Ltd. v. Union of India, (1980) 3 SCC 625

Facts: Clauses inserted into Article 368 by the Forty-second Amendment provided that there shall be no limitation on the constituent power of Parliament to amend the Constitution and that no amendment shall be called in question in any court on any ground. Section 4 of the Amendment also gave certain Directive Principles primacy over the fundamental rights in Articles 14 and 19. Both were challenged.

Held: The Supreme Court struck down both provisions. It held that the limited amending power is itself a basic feature of the Constitution, and that a provision purporting to remove all limitations on that power, and to exclude judicial examination of amendments, destroys the basic structure; judicial review is a fundamental aspect of the constitutional scheme, since a Constitution that confers limited powers and then forbids any court from enquiring whether those limits have been observed provides no guarantee at all. On section 4, the Court held that the harmony and balance between fundamental rights and directive principles is itself part of the basic structure, and that giving the Principles absolute primacy would destroy it. The Court emphasised that the Constitution is founded on the bedrock of the balance between Parts III and IV.

Ratio: Judicial review is part of the basic structure, and limitations on power are meaningless without a court to enforce them. This is the constitutional foundation on which administrative law in India rests.

3. Where the Two Meet: Discretion and Equality

📖 State of West Bengal v. Anwar Ali Sarkar, AIR 1952 SC 75

Facts: A State Act empowered the Government to constitute special courts and to direct that any case or class of cases be tried by them, the special procedure omitting several safeguards of the ordinary criminal trial. The Act laid down no criteria by which the Government was to decide which cases went to the special courts, leaving the selection entirely to executive discretion. A person tried by a special court challenged the provision under Article 14.

Held: The Supreme Court struck down the provision. It held that Article 14 forbids class legislation but permits reasonable classification, which requires an intelligible differentia and a rational relation to the object of the Act; a provision that leaves the selection of cases wholly to the unguided discretion of the executive makes no classification at all and confers a power to discriminate, which is precisely what the Article forbids. The Court held that the vice lay not in the special procedure as such but in the absence of any principle governing which persons would be subjected to it, so that two persons accused of the same offence might be tried under different procedures according to executive choice. The Court held the discrimination to be inherent in the provision itself.

Ratio: A statute conferring an unguided discretion to subject selected persons to a different procedure violates Article 14, since a power to discriminate without any governing principle is not a classification at all.

The decision is a constitutional law case by subject and an administrative law case by effect. Its holding, that a power conferred without guiding principle offends equality, became the foundation of the Indian approach to administrative discretion, and explains why the requirement of stated criteria, published policy and recorded reasons runs through this subject.

4. Why the Boundary Is Indistinct in India

The grounds of review are constitutional. Arbitrariness under Article 14, proportionality where Article 19 is engaged, and fairness under Article 21 are constitutional standards applied to administrative action.
The remedies are constitutional. The writ jurisdictions under Articles 32 and 226 are the principal remedies in administrative law, and they are conferred by the Constitution.
Judicial review is part of the basic structure, so the foundation of administrative law cannot be removed by ordinary law or even by amendment (Minerva Mills).
Natural justice has a constitutional footing, being read into Articles 14 and 21 rather than resting only on the common law.
The State is constitutionally defined. Article 12 determines which bodies the fundamental rights bind, and so which are subject to the fullest administrative law obligations.
Liability is constitutional as well as private. Compensation for the violation of fundamental rights operates alongside the ordinary law of tort.
Tribunals are constitutionally regulated, Articles 323A and 323B governing their creation and the case law their independence.

5. What Remains Distinctly Administrative Law

Delegated legislation, its limits, publication, laying and control, which the Constitution barely addresses.
The detail of natural justice, including notice, disclosure, cross-examination, representation and the inquiry report.
The classification of functions as legislative, administrative or quasi-judicial, and the consequences of each.
The doctrines governing discretion, including relevant considerations, fettering, dictation and improper purpose.
Institutional design, covering tribunals, corporations, regulators, ombudsmen and audit.
Administrative liability in tort and contract, and the machinery of grievance redress.
Procedure and practice, including alternative remedy, delay, standing and the moulding of relief.

⚠ In India the older distinction describes emphasis rather than separation

Textbooks written for systems without a written constitution can treat administrative law as an essentially common law subject, in which the courts supply standards of fairness and reasonableness of their own making and the constitutional dimension arises only occasionally. That description does not fit India. Here the ground on which an administrative order is quashed is usually Article 14, the remedy is usually Article 226, the fairness required is read into Article 21, and the jurisdiction to grant relief is protected as part of the basic structure. The subjects are still usefully distinguished by their emphasis, constitutional law examining the framework and administrative law the working of it, but they are not separate bodies of law, and an argument in either field frequently turns on a proposition belonging to the other.

6. The Position in Summary

Constitutional law concerns the structure of the State and the rights of the individual; administrative law concerns the exercise of power by administrative authorities, the older account treating the first as the organs at rest and the second as the organs in motion.
Judicial review is part of the basic structure, since limitations on power are meaningless without a court to enforce them, and this is the foundation on which Indian administrative law rests (Minerva Mills).
A statute conferring unguided discretion to select persons for different treatment violates Article 14, which is the constitutional source of the Indian law on administrative discretion (Anwar Ali Sarkar).
The boundary is indistinct in India because the grounds of review, the remedies, the footing of natural justice, the definition of the State and the regulation of tribunals are all constitutional.
What remains distinctly administrative law is delegated legislation, the detail of natural justice, the classification of functions, the doctrines of discretion, institutional design, liability and procedure.
