Jurisprudence, Schools of Legal Thought and the Constitution of India
Jurisprudence is the study of the nature of law itself — not what a particular statute says, but what "law" is, where it comes from, and why it binds. Paper 1's opening topic asks a Company Secretary to hold two different kinds of knowledge at once: the abstract theory of law (jurisprudence and its schools), and the concrete constitutional architecture (Fundamental Rights, Directive Principles, legislative competence and writs) that every other law on this syllabus ultimately sits underneath.
Both halves are tested as fact-recall — name the school, name the article, state the category — more than as essay-style argument.
1. Sources of law
Indian legal education recognises three sources of law: legislation, precedent and custom. Legislation is law deliberately made by a competent legislature and is the most direct, authoritative source in a modern legal system. Precedent is judge-made law arising from decided cases — in India, Article 141 of the Constitution makes the Supreme Court's law declared binding on all courts within India, the constitutional foundation of the doctrine of stare decisis ("to stand by things decided").
Custom is a long-standing community practice that has acquired the force of law through consistent observance, and remains the historical basis of much of India's personal law.
Salmond's classical jurisprudence adds a supplementary distinction worth knowing: a formal source is the source from which a rule derives its legal force (the state's authority), while a material source is where the actual content of the rule came from (custom, juristic writing, foreign law). This distinction is occasionally tested as a direct definitional question.
2. The five schools of jurisprudence
Each school answers "what is law, and where does its authority come from" differently, and each is associated with named thinkers worth memorising as a fixed pair. The table below is this topic's single most examinable structure.
| School | Core claim | Key thinkers |
|---|---|---|
| Natural Law | Law must align with inherent, universal moral principles; an unjust law is not truly law | Aristotle, Aquinas, Grotius, Locke, Rousseau; Finnis (modern revival) |
| Analytical (Austinian) Positivism | Law is the command of a sovereign, backed by a sanction; law is separated from morality — "law as it is" | John Austin (founder); Bentham; Kelsen (pure theory of law); H.L.A. Hart (modern positivism) |
| Historical School | Law evolves organically out of a people's customs and shared spirit (Volksgeist), not deliberate design | Savigny; Henry Maine (the "status to contract" thesis) |
| Sociological School | Law is an instrument of social control and "social engineering," and should be studied by its actual effect on society | Roscoe Pound; Ehrlich; Duguit |
| Realist School | Law is what courts and judges actually do in practice, not what statute books say — "law in action" over "law in books" | Oliver Wendell Holmes; Jerome Frank; Karl Llewellyn |
Austin's Analytical School is the most frequently tested in isolation, since its own internal structure is itself examinable: Austin defined law as the command of a political sovereign, addressed to a subject, backed by a sanction for disobedience — a definition later criticised by Hart and others for ignoring customary and constitutional law that binds even the sovereign itself.
The Historical School's "status to contract" thesis, associated with Henry Maine, is a specific, nameable claim worth stating precisely: Maine argued that the movement of progressive societies has been a movement from a society organised around fixed status (birth, caste, family position) toward one organised around freely negotiated contract between individuals — a thesis often illustrated using the shift from feudal obligation to modern commercial contract law.
3. The Constitution: Fundamental Rights
Part III of the Constitution, Articles 12 to 35, contains the Fundamental Rights — enforceable directly by the courts, unlike the Directive Principles. They fall into six categories:
| Category | Articles | Core content |
|---|---|---|
| Right to Equality | 14-18 | Equality before law, prohibition of discrimination, equality of opportunity in public employment, abolition of untouchability and titles |
| Right to Freedom | 19-22 | Six freedoms (speech, assembly, association, movement, residence, profession), protection in respect of conviction for offences, protection of life and personal liberty, protection against arrest and detention |
| Right against Exploitation | 23-24 | Prohibition of traffic in human beings and forced labour; prohibition of child labour in hazardous employment |
| Right to Freedom of Religion | 25-28 | Freedom of conscience and free profession, practice and propagation of religion; freedom to manage religious affairs; freedom from religious instruction in wholly state-funded institutions |
| Cultural and Educational Rights | 29-30 | Protection of the interests of minorities; the right of minorities to establish and administer educational institutions |
| Right to Constitutional Remedies | 32 | The right to move the Supreme Court directly for enforcement of Fundamental Rights — famously called the "heart and soul" of the Constitution |
A frequently tested historical fact: the Right to Property was originally a seventh category of Fundamental Right (under the original Articles 19(1)(f) and 31), but the 44th Constitutional Amendment Act, 1978 removed it from Part III. Property is now only a legal right under Article 300A — enforceable, but not a Fundamental Right, and therefore not directly protected by the special remedies available under Article 32.
A candidate who lists property as a current Fundamental Right is making one of this topic's most common errors.
4. The Constitution: Directive Principles of State Policy
Part IV, Articles 36 to 51, contains the Directive Principles of State Policy (DPSP) — principles the state is directed to apply in making law, but which Article 37 expressly declares are not enforceable by any court. Article 37 also states that despite being non-justiciable, the DPSP are "fundamental in the governance of the country," and it is the state's duty to apply them.
Several individual DPSP articles are worth knowing by number, since questions often ask for a specific article rather than a general description:
- Article 38: the state shall promote the welfare of the people by securing a social order with social, economic and political justice.
- Article 39: principles of policy including equal pay for equal work.
- Article 39A: equal justice and free legal aid.
- Article 40: organisation of village panchayats.
- Article 41: right to work, to education, and to public assistance in certain cases.
- Article 43: a living wage for workers.
- Article 43A: workers' participation in management of industries.
- Article 44: a Uniform Civil Code for citizens.
- Article 48A: protection and improvement of the environment and safeguarding of forests and wildlife.
- Article 51: promotion of international peace and security.
The Fundamental Rights vs. Directive Principles distinction is the single most conceptually tested pairing in this section: Fundamental Rights are justiciable (a court can strike down a law that violates them), while Directive Principles are non-justiciable (a court cannot compel the state to implement one, however desirable).
5. Legislative competence and the Seventh Schedule
Article 246, read with the Seventh Schedule, divides law-making power between Parliament and the State Legislatures across three lists. The Union List (List I) contains subjects on which only Parliament may legislate (defence, foreign affairs, currency). The State List (List II) contains roughly 61 subjects reserved for the state legislatures alone (police, public health, agriculture).
The Concurrent List (List III) contains subjects both Parliament and the state legislatures may legislate on (criminal law, marriage, labour — the last of which is why the four Labour Codes needed both central and state-level rule notification).
Where a state law under the Concurrent List conflicts with a central law on the same subject, the central law prevails — this is the doctrine of repugnancy, and the general hierarchy on conflict runs Union List first, then Concurrent List, then State List.
6. The five writs
Article 32 empowers the Supreme Court, and Article 226 empowers the High Courts, to issue five kinds of writs — but the two articles' scope is not identical, and the difference is a commonly tested point. Article 32 can be invoked only for the enforcement of Fundamental Rights.
Article 226 is broader: a High Court can issue a writ both for enforcement of Fundamental Rights and "for any other purpose," which extends to enforcement of ordinary legal and statutory rights as well.
| Writ | What it does |
|---|---|
| Habeas corpus | "You shall have the body" — produce a detained person before the court to test the legality of the detention |
| Mandamus | "We command" — directs a public authority to perform a public duty it has failed to perform |
| Prohibition | Issued by a superior court to a lower court/tribunal, forbidding it from continuing proceedings beyond its jurisdiction |
| Certiorari | Quashes an order already passed by a lower court/tribunal/authority acting without or in excess of jurisdiction |
| Quo warranto | "By what authority" — questions the legal right of a person to hold a public office |
Worked Examples
Example 1. A statute is challenged on the ground that it is technically valid (properly passed by a competent legislature) but is morally unjust. Which school of jurisprudence would treat this challenge as legally irrelevant, and which would treat it as central?
The Analytical (Austinian) Positivist school treats validity as a purely formal question — a command of the sovereign backed by a sanction is law regardless of its moral content — so it would treat the moral challenge as legally irrelevant to the statute's validity. The Natural Law school treats alignment with inherent moral principles as central to whether something is truly "law" at all, so it would treat the same challenge as going to the heart of the matter.
Example 2. A judge decides a difficult case not strictly by applying the written statute, but based on how similar disputes have actually been resolved in practice by courts. Which school of jurisprudence does this decision-making style best illustrate?
The Realist School — its central claim is that law is what courts and judges actually do ("law in action"), not merely what is written in statute books ("law in books").
Example 3. A candidate lists the Right to Property under Article 19(1)(f) as a current Fundamental Right in an answer on the Right to Freedom category. Identify the error and state the correct current position.
The error is treating the Right to Property as a current Fundamental Right. The 44th Constitutional Amendment Act, 1978 removed it from Part III; it survives today only as a legal right under Article 300A, not as a Fundamental Right, and is therefore not directly enforceable through Article 32.
Example 4. A state law on a Concurrent List subject directly conflicts with a central law on the same subject, and neither has received the President's assent under the relevant proviso. Which law prevails?
The central (Parliament's) law prevails, under the doctrine of repugnancy — the general hierarchy on conflict runs Union List, then Concurrent List, then State List.
Example 5. A petitioner wants a writ against a public authority for violation of an ordinary statutory right that is not a Fundamental Right. Can the petitioner approach the Supreme Court under Article 32, the High Court under Article 226, or both?
Only the High Court under Article 226, since Article 226's scope extends to "any other purpose" beyond Fundamental Rights, while Article 32 is available only for enforcement of Fundamental Rights specifically.
Example 6. A person is detained by the police, and their family wants the court to examine whether the detention is lawful and to secure the person's release if it is not. Which writ is appropriate?
Habeas corpus — it requires the detaining authority to produce the detained person before the court so the legality of the detention can be tested.
Example 7. Explain, using Henry Maine's own terminology, the historical thesis associated with him about how legal relationships change as a society progresses.
Maine's "status to contract" thesis holds that the movement of progressive societies has been a movement away from legal relationships fixed by status (birth, caste, family position) and toward relationships freely negotiated through contract between individuals — illustrated by the shift from feudal, birth-based obligation toward modern commercial contract law.
Summary
Jurisprudence studies the nature of law itself through three recognised sources (legislation, precedent, custom) and five named schools of thought — Natural Law, Analytical (Austinian) Positivism, the Historical School, the Sociological School and the Realist School — each with its own thinkers and central claim about what makes something "law."
The Constitution's Part III (Fundamental Rights, Articles 12-35, six categories) is directly enforceable by courts, while Part IV (Directive Principles, Articles 36-51) is expressly non-justiciable under Article 37 though still "fundamental in governance" — the Right to Property's 1978 removal from Part III to the ordinary legal right under Article 300A is a specific, frequently tested fact.
Article 246 and the Seventh Schedule divide law-making power across the Union, State and Concurrent Lists, with central law prevailing on repugnancy, and Articles 32 and 226 empower the Supreme Court and High Courts respectively to issue five writs — with Article 226's "any other purpose" scope making it broader than Article 32's Fundamental-Rights-only jurisdiction.
