Every case cited here has been checked to exist — the citation resolves and names the right parties. The propositions attributed to each case have not been verified line by line against the judgment. Case names link through to the full judgment: read it before quoting a holding in an examination answer, and never carry a proposition from notes into court on trust.
1. Meaning and definitions
A constitution is the body of fundamental rules, written or unwritten, which establishes the organs of government, distributes power among them, fixes their relationship with one another and with the citizen, and sets limits on the exercise of that power. Every state has one, because every state must have some settled answer to the questions “who governs, by what authority, and within what limits.”
- Lord Bryce: a constitution is “a frame of political society, organised through and by law; that is to say, one in which law has established permanent institutions with recognised functions and definite rights.”
- Gilchrist: the body of rules or laws, written or unwritten, which determine the organisation of government, the distribution of powers to its various organs and the general principles on which these powers are to be exercised.
- K.C. Wheare (Modern Constitutions) uses the word in two senses: the whole system of government of a country, the collection of rules, legal and non-legal, which govern it; and in the narrower sense, the selection of those rules embodied in one document or a few closely related documents.
- Aristotle, who collected and compared 158 Greek constitutions, called it the way of life the state has chosen for itself: the arrangement of offices, especially the supreme office.
2. Importance of a constitution
- It creates the organs of government and tells each what it may do. Without it, legislature, executive and judiciary have no defined existence.
- It limits power. This is the idea of constitutionalism: government according to rules, not according to the will of the ruler. A constitution that only creates power and does not restrain it is a constitution in name only.
- It protects rights. Bills of rights (the American first ten amendments, Part III of the Indian Constitution) put certain freedoms beyond the reach of ordinary majorities.
- It supplies legitimacy. “We the people” in the American and Indian preambles locates authority in the people.
- It gives stability and continuity. Governments change; the rules by which they change do not, except by the amending process.
- It states national goals, as the Directive Principles of State Policy do in India and as the Irish Constitution of 1937 did before it.
- In a federation it is the treaty between centre and units, dividing powers and protecting each against the other.
3. Classification
The old classification (Aristotle) was by the number of rulers: monarchy, aristocracy and polity, with their corrupt forms tyranny, oligarchy and democracy. Modern writers classify on several bases at once. A single constitution falls into several classes; the Indian Constitution is written, partly rigid and partly flexible, enacted, federal with unitary features, parliamentary and republican.
| Basis | Types | Examples |
|---|---|---|
| Form | Written / unwritten | USA, India / UK |
| Method of amendment | Rigid / flexible | USA, Switzerland / UK |
| Origin | Enacted / evolved | USA 1787, France 1958 / UK |
| Distribution of power | Unitary / federal | UK, France / USA, Switzerland |
| Executive-legislature relation | Parliamentary / presidential | UK, India / USA |
| Head of state | Monarchical / republican | UK, Japan / India, USA |
Written and unwritten
A written constitution is one whose basic rules are deliberately framed by a constituent body at a given time and set out in a single document, as in the USA (1787), India (1950) and France (1958). An unwritten constitution is one whose rules are found in no single document but in statutes, judicial decisions, conventions and usage, grown over centuries. The British constitution is the standard example: its sources include Magna Carta (1215), the Bill of Rights (1689), the Act of Settlement (1701), the Parliament Acts of 1911 and 1949, common-law decisions and a large body of conventions.
The distinction is one of degree. Much of the British constitution is in fact written, in statutes; and every written constitution grows conventions around it (the American cabinet, the two-party system, the nomination of presidential candidates by party conventions are nowhere in the text). The better terms are codified and uncodified.
Merits of a written constitution: certainty and precision; it is suited to a federation, where the division of powers must be fixed; rights are clearly guaranteed; it is less open to change by a passing majority. Demerits: it may be too rigid for a changing society; it leaves much to judicial interpretation, which can make judges the real makers of the constitution. Merits of an unwritten constitution: flexibility and capacity for growth; it reflects the customs of the people. Demerits: uncertainty; it suits only a politically mature, homogeneous people; rights are at the mercy of the legislature.
Rigid and flexible
Bryce introduced this classification. A flexible constitution can be amended by the ordinary legislature in the ordinary way, by a simple majority, so that constitutional law and ordinary law have the same status. In Britain an Act of Parliament changing the composition of the House of Lords passes like any other Act. A rigid constitution needs a special procedure: a special majority, ratification by the units of a federation, a referendum, or several of these. The US Constitution (Article V) and the Swiss Constitution are the leading rigid examples. The Indian Constitution is a mixture: some provisions change by simple majority, most by a special majority, and the federal provisions only with ratification by half the States. The detail is in the note on amendment of constitutions.
Rigidity protects the constitution against hasty change and protects minorities and federal units; its cost is that a needed reform may be blocked, pushing change into judicial interpretation or, in the extreme, revolution. Flexibility allows easy adjustment but gives no protection against a determined majority.
Enacted and evolved; unitary and federal; parliamentary and presidential
An enacted constitution is made at a definite time by a constituent assembly or convention (Philadelphia 1787; the Constituent Assembly of India, 1946–49). An evolved constitution is the product of gradual growth (Britain). The unitary and federal distinction is treated in the note on forms of government, and parliamentary and presidential in the note on the executive.
4. Conditions (essentials) of a good constitution
- Clarity and definiteness. The language should be precise, so that the powers of each organ and the rights of the citizen are not left in doubt.
- Brevity, with comprehensiveness. It should contain the fundamentals and leave detail to ordinary law. The American constitution, of seven articles, is often held up; the Indian, among the longest in the world, is criticised for its length, though its length came from the need to settle federal and administrative questions.
- A balance of rigidity and flexibility. Rigid enough to resist hasty change, flexible enough to be amended when needed.
- A declaration of rights enforceable through the courts.
- An independent judiciary to interpret the constitution and protect it.
- Separation of powers with checks and balances, so that no organ becomes supreme.
- Provision for popular sovereignty: universal adult franchise, periodic elections, responsible government.
- Suitability to the people. A constitution must fit the history, social structure and political maturity of the society it governs. Imported constitutions fail when the conditions are absent, as many post-colonial constitutions did.
- Provision for local self-government and decentralisation.
How this is examined
In the 80-mark paper, “Define the term constitution. Explain its kinds” (January 2026, 10 marks) and “What is meant by constitution? Explain the importance and classification of constitutions” (June 2025) are Unit I essays. In the 100-mark paper, “Define constitution. Explain briefly the types of constitution” was the first question in June 2025, and “conditions for a good constitution” was a short note in January 2026.
For the essay, give two definitions, a paragraph on importance, then the table of classes followed by a paragraph each on written/unwritten and rigid/flexible with merits and demerits. Close by placing India in each class. For the short note on a good constitution, list the conditions with one line each and an example.
