PHOENIX — The Navajo Nation is claiming that Arizona and several counties illegally discriminated against tribal members and kept them from having their votes counted.

Legal papers filed Tuesday in federal court cite a litany of problems that the tribe says make it difficult, if not impossible, for reservation members to cast early ballots. That includes the failure to provide instructions in the native language on how to fill them out and that the envelopes must be signed and dated.

The lawsuit says the problem was complicated this year by the fact that some counties refused to give residents time after the election to fix early ballots where the envelope was not signed or a signature did not match.

In pure numbers, that issue is highly unlikely to affect any of the races for statewide or legislative offices. More than 100 ballots were not counted, said Patty Ferguson-Bohnee, an attorney for the Navajo Nation.

But the lawsuit does not simply ask Judge Dominic Lanza to declare the voting practices illegal and prohibit them from occurring again. It also seeks a court order giving those whose ballots were not counted five days to remedy the problem.

That five days would run from whatever date the judge issued an order. And there is no date at this point for even a hearing. That, in turn, could prevent the state from certifying the election results as scheduled on Dec. 3.

According to the lawsuit, the Navajo Nation asked Coconino, Apache and Navajo counties, the three Arizona counties within its borders, to establish additional voter registration and early voting sites on the reservation to assist tribal members.

“For various and unsubstantiated reasons, the counties denied the nation’s request,” the suit says. “The inadequate voting sites resulted in tribal members making mistakes on their ballots. Workers at an early voting site could have identified and corrected the signature issue.”

Complicating matters, the lawsuit states, is that ballot translations in the Navajo language are only provided orally, as are instructions on how to complete an early ballot.

But that was no help for those who received early ballots by mail.

“And there were no radio announcements or other communications in the Navajo language explaining the requirements of completing the ballot affidavit to Navajo language speakers,” Ferguson-Bohnee said. “Navajo language speakers did not have an equal opportunity to participate in early voting opportunities.”

Moreover, a settlement of a lawsuit filed by the Arizona Republican Party directed each county to allow residents to correct ballot deficiencies after Election Day.

But that deal said each county could use the same procedures that had been in place before Election Day, rather than requiring a uniform procedure statewide. This lawsuit says the practices of counties on the reservation, which limit opportunities to correct ballot deficiencies, means citizens of the Navajo Nation have less opportunity to participate in the political process and elect candidates of their choice.

“The state has no legitimate interest in enforcing an agreement between political parties that allows early voters to correct some deficiencies and not others,” Ferguson-Bohnee wrote.

The Apache County Recorder’s Office declined to comment on the lawsuit; messages left for the recorders in Coconino and Navajo counties were not immediately returned. A hearing on the matter has been set for Monday, Nov. 26.
