New restrictions enacted in 2019: Restrictions on access to emergency early and absentee voting and extension of voter ID requirements to early voting.

New restriction(s) in place for the first time in 2016: Limitations on mail-in ballot collection.

Background: In 2016, a Republican-controlled legislature passed a bill limiting collection of mail-in ballots and making it a felony to knowingly collect and turn in another voter’s completed ballot, even with that voter’s permission (the law has exceptions for direct family members, caregivers, and postal-service employees). Gov. Doug Ducey (R) signed the bill, which went into effect in the summer of 2016.

Other restrictions in play: In 2004, voters approved a referendum requiring documentary proof of citizenship to register to vote. In June 2013, the U.S. Supreme Court invalidated this measure as it applied to the federal voter registration form. And in 2018, as part of the settlement where a Ninth Circuit panel affirmed the district court in a 2-1 decision.
