Understanding the Constitution

A Constitution is the body of fundamental principles or established precedents according to which a state or other organization is acknowledged to be governed. It serves as the supreme law of the land, defining the relationship between the government and its citizens.

Sources of a Constitution

• History and Customs: The traditions and historical experiences of a people.
• Statutes/Acts of Parliament: Laws passed by the legislature that have constitutional significance.
• Judicial Precedents: Interpretations and decisions made by superior courts (case law).
• Constitutional Conventions: Unwritten practices and customs that are observed out of habit or convenience.
• International Treaties: Agreements between nations that influence domestic legal frameworks.
• Opinions of Jurists: Writings and views of renowned legal experts and political scientists.

Functions of a Constitution

• Framework of Government: It defines the structure and powers of the executive, legislature, and judiciary.
• Protection of Rights: It guarantees the fundamental human rights of citizens.
• Limitation of Power: It prevents tyranny by setting boundaries for government authority.
• Source of Legitimacy: It provides the legal basis for the existence of the state.
• Conflict Resolution: It provides mechanisms for resolving disputes between tiers of government.

Types of Constitutions

1. Written vs. Unwritten

• Written (Codified): A single legal document containing the fundamental laws of the state. Example: USA, Nigeria.
• Unwritten (Uncodified): Fundamental laws are not found in one single document but are spread across statutes, conventions, and judicial decisions. Example: United Kingdom.

2. Rigid vs. Flexible

• Rigid: A constitution that requires a special and difficult procedure for amendment. Example: USA, Nigeria.
• Flexible: A constitution that can be amended easily, just like an ordinary law, by a simple majority in the legislature. Example: United Kingdom.

3. Unitary vs. Federal

• Unitary: Power is concentrated in the central government.
• Federal: Power is shared between the central government and component units (states/regions).
