The Czech Republic is a unitary state, with a civil law system based on the continental type, rooted in Germanic legal culture. The basis of the legal system is the Constitution of the Czech Republic adopted in 1993. The Penal Code is effective from 2010. A new Civil code became effective in 2014. The court system includes district, county, and supreme courts and is divided into civil, criminal, and administrative branches. The Czech judiciary has a triumvirate of supreme courts. The Constitutional Court consists of 15 constitutional judges and oversees violations of the Constitution by either the legislature or by the government. The Supreme Court is formed of 67 judges and is the court of highest appeal for most legal cases heard in the Czech Republic. The Supreme Administrative Court decides on issues of procedural and administrative propriety. It also has jurisdiction over certain political matters, such as the formation and closure of political parties, jurisdictional boundaries between government entities, and the eligibility of persons to stand for public office. The Supreme Court and the Supreme Administrative Court are both based in Brno, as is the Supreme Public Prosecutor's Office.
