In Iran, after the revolution in 1979, there are two different court systems: the civil courts and the revolutionary courts. The judicial system is mainly under the authority of the religious leader who is named Faghih. All laws are driven by Islam (the Islamic laws). The parliament is responsible to legislate laws, but the supreme has the superpower to legislate on constitutional matters. The chief justice of the supreme court of the judicial system is appointed by the leader of the revolution. Most of the judges are chosen among the clergymen and a few of them are from the educated judges. All conditions for marketing, property, life, dwelling are based on the Islamic laws.
