Some members of the Navajo Nation recently filed a lawsuit saying mail-in voting in southern Utah disenfranchises tribal voters. The case is now headed to trial.

The trial will start in March in the case filed by the Navajo Nation Human Rights Commission and the American Civil Liberties Union of Utah. ACLU spokesman John Mejia said mail-in ballots are harder for Navajo voters to receive because many don't have mailboxes and can be difficult to use for people who speak Navajo.

Mejia also said the reduction in physical polling places means people in rural areas might have to drive hours to reach an early-voting site.

Similar legal clashes have been waged in Nevada, Montana and the Dakotas over a variety of issues involving reservations and the Voting Rights Act.
