The Judiciary of Russia interprets and applies the law of Russia. It is defined under the Constitution and law with a hierarchical structure with the Constitutional Court, Supreme Court, and Supreme Court of Arbitration at the apex. The district courts are the primary criminal trial courts, and the regional courts are the primary appellate courts. The judiciary is governed by the All-Russian Congress of Judges and its Council of Judges, and its management is aided by the Judicial Department of the Supreme Court, the Judicial Qualification Collegia, the Ministry of Justice, and the various courts' chairpersons. And although there are many officers of the court, including jurors, the Prosecutor General remains the most powerful component of the Russian judicial system.
