ARIZONA STATE LEGISLATURE v. ARIZONA INDEPENDENT REDISTRICTING COMMISSION ET AL.
APPEAL FROM THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF ARIZONA
No. 13–1314. Argued March 2, 2015—Decided June 29, 2015
Under Arizona’s Constitution, the electorate shares lawmaking authority on equal footing with the Arizona Legislature. The voters may adopt laws and constitutional amendments by ballot initiative, and they may approve or disapprove, by referendum, measures passed by the Legislature. Ariz. Const., Art. IV, pt. 1, §1. “Any law which may be enacted by the Legislature … may be enacted by the people under the Initiative.” Art. XXII, §14.
In 2000, Arizona voters adopted Proposition 106, an initiative aimed at the problem of gerrymandering. Proposition 106 amended Arizona’s Constitution, removing redistricting authority from the Arizona Legislature and vesting it in an independent commission, the Arizona Independent Redistricting Commission (AIRC). After the 2010 census, as after the 2000 census, the AIRC adopted redistricting maps for congressional as well as state legislative districts. The Arizona Legislature challenged the map the Commission adopted in 2012 for congressional districts, arguing that the AIRC and its map violated the “Elections Clause” of the U. S. Constitution, which provides: “The Times, Places and Manner of holding Elections for Senators and Representatives shall be prescribed in each State by the Legislature thereof; but the Congress may at any time by Law make or alter such Regulations.” Because “Legislature” means the State’s representative assembly, the Arizona Legislature contended, the Clause precludes resort to an independent commission, created by initiative, to accomplish redistricting. A three-judge District Court held that the Arizona Legislature had standing to sue, but rejected its complaint on the merits.
