Federal government of Nigeria
The federal government of Nigeria is composed of three distinct branches: legislative, executive, and judicial, whose powers are vested by the Constitution of Nigeria in the National Assembly, the President, and the federal courts, including the Supreme Court, respectively.
Nigeria is a federal republic, with executive power exercised by the president. The president is the head of state, the head of government, and the head of a multi-party system. Nigerian politics takes place within a framework of a federal, presidential, representative democratic republic, in which executive power is exercised by the government. Legislative power is held by the real government and the two chambers of the legislature: the House of Representatives and the Senate. Together, the two chambers make up the law-making body in Nigeria, called the National Assembly, which serves as a check on the executive arm of government. The highest judiciary arm of government in Nigeria is the Supreme Court of Nigeria which was created after independence and also practices Baron de Montesquieu's theory of the separation of powers based on the United States system and also practises checks and balances.
Legal system
The law of Nigeria is based on the rule of law, the independence of the judiciary, and British common law. The common law in the legal system is similar to common-law systems used in England and Wales and other Commonwealth countries. The constitutional framework for the legal system is provided by the Constitution of Nigeria.- English Law, which is derived from its colonial past with Britain;
- Common law, case law development since colonial independence;
- Customary law, which is derived from indigenous traditional norms and practices;
- Sharia law, law used in some states in the northern region.
Legislation as a source of Nigerian law
The two fundamental sources of Nigerian law through legislation areActs of British parliament, popularly referred to as statutes of general application.
Local legislation. There were other sources which though subsumed in Nigerian legislations were distinctly imported into the Nigerian legal systems. They are called the criminal and penal codes of Nigeria.
Nigerian statutes as sources of Nigerian law
Nigerian legislation may be classified as follows. The colonial era until 1960, post independence legislation 1960-1966, the military era 1966-1999.The post independence legislation 1960-1966
The grant of independence to Nigeria was a milestone in the political history of the country. This period witnessed the consolidation of political gains made during the colonial era. Politicians genuinely focused their lapses in the polity. It achieved for herself a republican status by shaking off the last vestiges of colonial authority. However, despite the violent violation of its provisions, the constitution remained the subsequent administrations.Military regime, 1966-1999
The breakdown of law and order which occurred in the period under review would not be attributed to any defect in the Nigerian legal system. Corrupt practices both in the body politic and all aspects of Nigerian life eroded efficiency and progress. There were 8 coups generally five were successful and 3 were unsuccessful.Executive branch
The president is elected through universal suffrage. He or she is both the chief of state and head of government, heading the Federal Executive Council, or cabinet.The executive branch is divided into Federal Ministries, each headed by a minister appointed by the president. The president must include at least one member from each of the 36 states in his cabinet. The President's appointments are confirmed by the Senate of Nigeria. In some cases, a federal minister is responsible for more than one ministry, or a minister may be assisted by one or more ministers of State.
Each ministry also has a Permanent Secretary, who is a senior civil servant.
The ministries are responsible for various parastatals, such as universities, the National Broadcasting Commission, and the Nigerian National Petroleum Corporation.
However, some parastatals are the responsibility of the Office of the Presidency, such as the Independent National Electoral Commission, the Economic and Financial Crimes Commission and the Federal Civil Service Commission.
Legislative branch
The National Assembly of Nigeria has two chambers: the House of Representatives and the Senate. The House of Representatives is presided over by the Speaker of the House of Representatives. It has 360 members, who are elected for four-year terms in single-seat constituencies. The Senate, which has 109 members, is presided over by the President of the Senate. 108 members are elected for four-year terms in 36 three-seat constituencies, which correspond to the country's 36 states. One member is selected in the single-seat constituency of the federal capital.Judicial branch
The judicial branch consists of the Supreme Court of Nigeria, the Court of Appeals, the High Courts, and other trial courts such as the Magistrates', Customary, Sharia and other specialised courts. The National Judicial Council serves as an independent executive body, insulating the judiciary from the executive arm of government. The Supreme Court is presided over by the Chief Justice of Nigeria and thirteen associate justices, who are appointed by the President of Nigeria on the recommendation of the National Judicial Council. These justices are subject to confirmation by the Senate.| Office | Office holder | Assumed office |

The Nigerian Army, which is the largest of the services, has about 60,000 personnel, deployed between two mechanized infantry divisions, one composite division, the Lagos Garrison Command, and the Abuja-based Brigade of Guards.
