A constitution is the supreme law of a country, setting out the structure of government, the powers of different branches, and the fundamental rights of citizens. It provides the legal foundation for all other laws and ensures that government authority is exercised within defined limits.
  • Constitutions establish the framework of government and legal order.
  • They define how power is distributed and exercised.
  • They protect fundamental rights and freedoms.
  • All other laws must conform to the constitution.

Written and Unwritten Constitutions

Written and unwritten constitutions are the two main types.
  • Written Constitution: A single, formal document that clearly outlines constitutional provisions (e.g., U.S. Constitution).
  • Unwritten Constitution: A system based on statutes, judicial decisions, conventions, and traditions rather than a single document (e.g., UK).
The United Kingdom has an unwritten constitution.
The United States is known for its written constitution adopted in 1787.
Typical features include the preamble, organization of government, distribution of powers, and fundamental rights.
An unwritten constitution is based on statutes, judicial decisions, and conventions.

Functions of a Constitution

A constitution performs several critical functions in a political and legal system:
  • Establishes the structure and organization of government.
  • Allocates powers and responsibilities among branches (separation of powers).
  • Protects fundamental rights and freedoms of individuals.
  • Provides a legal framework for making and enforcing laws.
  • Ensures stability, continuity, and predictability in governance.
  • Defines procedures for constitutional amendment and change.
Regulating daily business transactions is not a function of a constitution.
Constitutions define government structure, protect rights, and regulate power distribution.

Constitutional Law

Constitutional law is the body of law derived from a constitution.
Constitutional law is the body of law that arises from and interprets a constitution. It governs the relationship between different branches of government, and between the government and citizens, and ensures that all laws comply with constitutional principles.
