The suit filed June 8 in U.S. District Court in Reno argues voters who choose that option are disenfranchised because votes for “none” are ignored when it comes to the outcome of a race.
Under state law, “none” cannot win an election, even if it gets the most votes. The election goes to the actual candidate who receives the highest number of votes.
The lawsuit argues that provision nullifies the will and rights of voters.
The suit names the state of Nevada and Secretary of State Ross Miller as defendants. It was first reported Tuesday by Las Vegas political columnist Jon Ralston.
The Associated Press also reported Tuesday that voting advocacy groups are suing Nevada, alleging the state is violating the National Voter Registration Act of 1993 by refusing to help low-income residents register to vote.
NAACP branches in Las Vegas and Sparks are joining the National Council of La Raza in the civil lawsuit filed Monday in U.S. District Court in Reno.
It asks a judge to order the state to comply with the federal law to properly offer voter registration to people applying for public assistance benefits.
Spokeswomen for Nevada Secretary of State Ross Miller and Health and Human Services chief Michael Willden declined comment on the lawsuits.
The advocates says the number of voter registration applications submitted at public assistance offices statewide has fallen from more than 39,000 before 2000 to fewer than 1,700 in 2010.
