The Nebraska State Racing Commission's order allowing Fonner Park to add historical horse racing terminals at the Grand Island track is unconstitutional and should be overturned, two Hall County residents said in a lawsuit. Duane Fuller of Grand Island and Jeffery Hayman of Doniphan filed the lawsuit against the commission and Fonner Park in Lancaster County District Court on Friday afternoon. Neither the Nebraska Constitution nor state law authorizes wagering using an electronic historical horse racing terminal, the two said in their lawsuit.
