Defense to possession; antique slot machines

(a) In any prosecution for possession of a slot machine or device as defined in G.S. 14-306, it is a defense that the slot machine was not intended to be used in the operation or promotion of unlawful gambling activity or enterprise and that the slot machine is an antique. For purposes of this section a slot machine manufactured 25 years ago or earlier is conclusively presumed to be an antique. (b) When a defendant raises the defense provided in subsection (a), any slot machine seized from the defendant shall not be destroyed or otherwise altered until a final court determination is rendered. If the court determines that the defense has been proved the slot machine shall be returned immediately to the defendant.
