The US Court of Appeals for the Ninth Circuit unanimously upheld a district court ruling striking down Arizona’s “reason to believe” voter registration law for violating the 1964 Civil Rights Act. Separately, a majority found the provision also violated the National Voter Registration Act. This Arizona law, which will remain blocked, would have required county recorders to subject registered voters to an unwarranted, discriminatory citizenship check whenever they had a “reason to believe” the voter is not a U.S. citizen.
