The IRC is a five-member commission that is responsible for redrawing congressional and legislative district boundaries in Arizona every ten years, following the U.S. Census. The IRC was created in 2000 when voters approved Proposition 106, removing responsibility for redistricting from the State Legislature in order to end gerrymandering—the practice of drawing boundaries that benefit politicians in office instead of the people of Arizona. The provisions of Proposition 106 became part of the Arizona Constitution.
The State Legislature’s attempt to retain control of the power to draw its own maps was rejected by the Supreme Court in 2015. The Court’s decision left intact the Independent Redistricting Commission’s full authority.
