The Constitution of the Russian Federation of 1993 spurred a significant reform of the Russian legal system. The Russian system, based on the tenets of civil law, has a three-branch court system. The three branches include a four-level “regular” court system with a court of last resort (Supreme Court of the Russian Federation), a three-level arbitration court system for business-related actions headed by the Supreme Arbitrazh Court of the Russian Federation, and a constitutional court system composed of one Supreme Court for constitutional actions. The “regular” court system is similar to the traditional hierarchical structure in many other countries. There are four levels of courts: the Supreme Court of the Russian Federation; supreme courts of the republics, krai, and oblast courts; and courts of cities of federal importance (i.e., Moscow and St. Petersburg). Almost every civil, criminal, or administrative action is initially heard in the People's Court.
