A has ruled in favor of a nude dancing club owner charged with violating Iowa's indecent exposure law.

Judge Timothy O'Grady ruled Friday that prosecutors failed to prove the club wasn't a theater.

Iowa law allows nudity at theaters, museums and other venues devoted to the arts or theatrical performances.

Fremont County's attorney charged club owner Clarence Judy after a 17-year-old girl climbed on stage at Shotgun Geniez in the tiny town of Hamburg and stripped off her clothing.
