The current Judiciary of Niger was established with the creation of the Fourth Republic in 1999. The constitution of December 1992 was revised by national referendum on 12 May 1996 and, again, by referendum, revised to the current version on 18 July 1999. It is based on the Code Napoleon "''Inquisitorial system''", established in Niger during French colonial rule and the 1960 Constitution of Niger. The Court of Appeals reviews questions of fact and law, while the Supreme Court reviews application of the law and constitutional questions. The High Court of Justice (HCJ) deals with cases involving senior government officials. The justice system also includes civil criminal courts, customary courts, traditional mediation, and a military court. The military court provides the same rights as civil criminal courts; however, customary courts do not. The military court cannot try civilians.
