The government of Niger is the apparatus through which authority functions and is exercised: the governing apparatus of Nigerien state. The current system of governance, since the Constitution 18 July 1999, is termed the Fifth Republic of Niger. It is a semi-presidential republic, whereby the President of Niger is head of state and the Prime Minister of Niger head of government. The officials holding these posts are chosen through a representative democratic process of national and local elections, in the context of a competing multi-party system. Executive power is exercised by the government. Legislative power is vested in both the government and the National Assembly. The judiciary is independent of the executive and the legislature: its Constitutional Court has jurisdiction over constitutional and electoral matters.
National government, has, since 1999, been supplemented by locally elected officials, who in turn choose representatives at the Departmental and Regional levels. Prior to 1999, these levels of government had always been appointed by the central government.
Central governance is carried out by professional administrative agencies, directed by the Office of the President and/or the Ministries headed by members of the National Assembly appointed to the post by the President. The remainder of Ministry offices are filled by non-political professional administrators. Local governance is carried out by local, departmental, and regional councils, the Ministry of Territorial Collectivities, officials chosen by these elected bodies, and professional government employees.
