PHOENIX (AP) – Arizona Attorney General Mark Brnovich will argue before the U.S. Supreme Court in a challenge to how state legislative districts were drawn.
Brnovich’s office said Tuesday he’ll present an argument adopted by Secretary of State Michele Reagan that said the maps violated the one-person, one-vote principal.
Eleven Republican voters sued Arizona’s Independent Redistricting Commission after new legislative maps were adopted in 2012. They claimed Republican voters were illegally shifted from some districts to make them more likely to elect Democrats to the state Legislature on the premise of complying with the federal Voting Rights Act.
A panel of federal judges found the commission did not violate the Constitution’s equal-protection clause.
The high court hears the Arizona case and a Texas elections case on Dec. 8.
