Arkansas violated the Voting Rights Act by limiting help to voters, a judge rules.

A federal judge ruled that Arkansas violated the Voting Rights Act with its six-voter limit for those who help people cast ballots in person, which critics had argued disenfranchised immigrants and people with disabilities.

In a 39-page ruling issued on Friday, Judge Timothy L. Brooks of the U.S. District Court in Fayetteville, Ark., wrote that Congress had explicitly given voters the choice of whom they wanted to assist them at the polls, as long as it was not their employer or union representative.
