The 1989 Navajo Nation Council Reforms, also known as the Title II Amendments were a series of Constitutional changes to the government structure of the Navajo Nation. Following 1985 reforms to the Judicial Branch, the reforms were meant to separate the powers of the Tribal Council (the legislative branch) the President (the executive branch) and the Supreme Court (the judicial branch) with a checks and balances system similar to that of the U.S. Constitution. The resolutions were adopted by the Council on December 15, 1989 and became law on April 11, 1990.[1]
