Prior to the
2023 Nigerien coup d'état, Niger's independent judicial system was composed of four higher courts — the Court of Appeals, the Supreme Court, the High Court of Justice and the Court of State Security — as well as lower criminal, civil and appeals courts. • The
Supreme Court of Niger is the highest judicial body of the State in administrative, judicial and financial matters. The Supreme Court hears cases appealed from lower civil and criminal courts, it only rules on the application of the law and constitutional questions: the lower Courts of Appeals may decide appeals on questions of fact and law. • The
Court of Appeals of Niger, one in each of Niger's eight
regions, reviews questions of fact and law in criminal and civil law, and rulings may be appealed to the Supreme Court of Niger. It may be called upon to provide rulings by certain constitutional triggers (elections, referendum, constitution revision) or by the request of the President, the Speaker of the
National Assembly, or by the vote of one-fifth of the members of the national assembly. When called upon to give binding rulings it is the final arbiter, and rulings must be carried out in 30 days. Most recently it came into prominence when required to offer a non-binding ruling of President
Mamadou Tandja's plan for a referendum on a new constitution. Its opposition, presented on 26 May 2009, triggered the President's dismissal of the National Assembly. • Crimes or misdemeanors committed by government officials in the exercise of their office are tried in the
High Court of Justice, a ''''. This court is composed of seven deputies elected from within the National Assembly on a provisional basis, and organised and instructed by the Supreme Court of Niger. • The
State Security Court, established under the rule of
Seyni Kountché in the 1970s is a military court for trying offenses committed by the military and police, but also enabling the
military of Niger to try civilians accused of crimes touching upon state secrets, defense, espionage, or internal security. The closing of the court was one of the first acts of the 1991 National Assembly, which led to the Third Republic. In 2007, some elements of the court were reestablished, but it may no longer try civilians. A legal practitioner with basic legal training, advised by an assessor knowledgeable in the society's traditions, heads these courts. The judicial actions of chiefs and customary courts are not regulated by formal law, and defendants can appeal a verdict in the formal court system. ==Legal profession==
