Redistricting in Arizona
The following timeline is a high-level overview outlining major redistricting events and activity in the state of Arizona over the last 10 years.
Census data delivered to Arizona.
The bipartisan Arizona Independent Redistricting Commission (AIRC) submitted congressional and state legislative maps to the Department of Justice (DOJ) for approval, yielding results that reflect the will of the voters.
The Arizona State Legislature, controlled by Republicans, sued the AIRC, arguing the commission cannot take congressional map-drawing power away from the state legislature.
After three years of litigation, the U.S. Supreme Court affirmed the AIRC's role in drawing Arizona's maps.
An attempt by Arizona Republicans to make the AIRC more partisan failed in the state Senate.
