Institutions of Government in Post-Independence Nigeria

In post-independence Nigeria, the government operates through three primary arms: the Legislature, the Executive, and the Judiciary. This structure is designed to promote the principle of Separation of Powers and Checks and Balances, ensuring that no single arm becomes absolute in its authority.

1. The Legislature (The National Assembly)

The legislature is the law-making body. In Nigeria's Fourth Republic, it is bicameral at the federal level, consisting of the Senate and the House of Representatives.

• Structure: The Senate has 109 members (3 from each of the 36 states plus 1 from the FCT). The House of Representatives has 360 members representing various federal constituencies.
• Functions: Law-making, oversight of executive agencies, approval of the national budget (Appropriation Bill), and confirmation of key executive appointments.
• Working: Laws start as 'Bills' which go through First Reading, Second Reading (debate on principles), Committee Stage (detailed scrutiny), Report Stage, and Third Reading before being sent to the other chamber and finally for Presidential Assent.

2. The Executive

The Executive arm is responsible for implementing laws and policies. It is headed by the President at the federal level and Governors at the state level.

• The Civil Service: This is the administrative tool of the executive. It is characterized by anonymity, neutrality, and permanence. Civil servants provide the technical expertise needed to run the government.
• Armed Forces and Police: The Nigerian Armed Forces (Army, Navy, Air Force) defend the territorial integrity, while the Nigeria Police Force is responsible for internal security, law enforcement, and maintaining public order.
• Functions: Policy formulation, maintenance of law and order, and management of international relations.

3. The Judiciary

The Judiciary interprets the laws and settles disputes between individuals, or between individuals and the state.

• Structure: Nigeria follows a hierarchical court system: Supreme Court (highest), Court of Appeal, Federal High Court/State High Court, Sharia/Customary Courts of Appeal, and Magistrate/Area Courts.
• Functions: Interpretation of the constitution, judicial review (declaring actions of other arms ultra vires if they contradict the constitution), and protection of fundamental human rights.
• Independence: To function effectively, the judiciary must be independent from the executive and legislature, achieved through secure tenure and financial autonomy.
