Summary
Background
The Arizona State Legislature sued the Arizona Independent Redistricting Commission (AIRC), an independent agency created by voter initiative (Proposition 106). Voters adopted Prop 106 in 2000 to move redistricting from the legislature to an independent commission. After the 2010 census the AIRC drew new congressional maps, and the legislature challenged those maps in federal court, arguing the U.S. Constitution’s Elections Clause requires redistricting to be done by the state’s representative legislature. A three-judge district court found the legislature had standing but rejected its constitutional claim; the Supreme Court granted review.
Reasoning
The Court framed the central question as whether “the Legislature” in the Elections Clause meant only the representative assembly or included a State’s chosen lawmaking methods, like ballot initiatives. The majority held redistricting is a legislative function but that state lawmaking can include initiatives and commissions. It relied on historical practice, cases such as Hildebrant and Smiley, and on federal statute 2 U.S.C. §2a(c), which recognizes state redistricting “in the manner provided by the laws thereof.” The Court concluded the legislature showed a concrete injury (so it had standing) but that the Elections Clause and §2a(c) permit Arizona’s commission to adopt congressional districts.
Real world impact
The ruling allows Arizona’s commission-drawn congressional map to govern elections and confirms that a State may adopt a voter-approved procedure to assign redistricting authority. The decision affects how other states may use initiatives or commissions for federal election rules. It resolves the constitutional question but leaves other legal claims against specific maps (for example Voting Rights Act challenges) open.
Dissents or concurrances
Chief Justice Roberts, joined by three Justices, and separate dissents from Justices Scalia and Thomas argued that “the Legislature” means the representative legislative body and that removing that body’s authority violates the Elections Clause.
