KANSAS CITY, Kan. (AP) — A federal trial is scheduled for May 2015 in a lawsuit challenging a Kansas law requiring voters to show photo identification at the polls.

U.S. Magistrate Gerald Rushfelt in Kansas City, Kan., set a schedule this week for hearing the lawsuit. Kansas Secretary of State Kris Kobach is being sued by elderly northeast Kansas residents Arthur Spry and Charles Hamner.

The law took effect in 2012. In the November election, ballots from Spry or Hamner weren’t counted because neither showed photo ID at the polls.

Both live in a retirement home in Overbrook. The lawsuit says neither man had a driver’s license, computer or access to the birth records needed to secure a photo ID.

The trial is expected to last three days, starting May 11, 2015.
