Under the secularist reign of Reza Shah many changes were made in Iran's judicial system, and the establishment of a fixed written law with appeals courts was one of them. In March 1926, Minister of Judicial Affairs Ali-Akbar Davar dissolved Iran's entire judiciary, with the approval of the parliament, and initiating a wave of fundamental restructuring and overhauling reforms with the aid of French judicial experts. By April 1927 Iran had 600 newly appointed judges in Tehran. Davar subsequently attempted to expand the new system into other cities of Iran through a programme involving training of 250 judges.
