An appeals court has upheld a 2016 Arizona law banning groups from collecting mail-in ballots from voters and delivering them.
The 9th Circuit Court of Appeals ruled Wednesday in a challenge filed by Democratic activist Rivko Knox, who said the law has caused her to stop delivering ballots for voters who request assistance.
The appeals court rejected Knox's arguments that the statute violates her free speech and due process rights and is trumped by federal laws governing postal deliveries.
The law bans anyone but caregivers or family members from delivering a completed early ballot to a polling place.
Both parties have used ballot collection to boost turnout during elections by going door to door and asking voters if they have completed their mail-in ballots.
Democrats, however, used it more effectively.
