The Commission was formed by the passage of Proposition 106 by the people of Arizona in the 2000 General Election. Proposition 106 amends the Arizona Constitution to create a five-member commission to redraw Congressional and Legislative district boundaries following the 2000 Census. Previously, the State Legislature was responsible for redrawing the lines. Many people believed this practice resulted in boundaries that served the politicians instead of the people of Arizona. The five-member Redistricting Commission acts independently of the State Legislature.
