The Tennessee Voter ID law is before the state supreme court.

In salient part:

The court heard arguments from the city of Memphis and two residents who are challenging the law. The city and the individual plaintiffs sued the state last year after election officials refused to accept a city-issued library card with a photo as voter identification.

The state attorney general's office argued that that the library card is issued by the city while the state's voter ID law passed in 2011 requires either a state-issued photo ID, federal identification or an ID issued from another state. Janet M. Kleinfelter, a deputy attorney general, also said the law was not so onerous that it would deprive people of the right to vote.

But attorneys representing the city said the votes of 650 people have not been counted in the last two elections because they lacked the proper identification.

"They were deprived of the right to vote," Nashville attorney George Barrett said. Barrett argued that the statute violates the Tennessee Constitution, which only requires someone to be a U.S citizen, a resident of the state, at least 18 and properly registered in order to vote.
