Missouri- Strip clubs and other aspects of the adult entertainment industry already face restrictions, but a case scheduled to be heard by the Missouri Supreme Court on Wednesday could mean even more restrictions.

The court will consider whether a law approved by lawmakers in 2005 that adds new drunken driving laws and restrictions on the adult entertainment industry violates the state constitution.

The state constitution requires that the subjects covered in legislation do not expand beyond its formal title.

The Missouri Association of Club Executives is challenging the law on these grounds and won a ruling from Cole County Circuit Judge Richard Callahan tossing out the law in 2005.

The association’s vice president Dick Snow said the group is not worried about the outcome of the appeal.

“I assume that the Supreme Court will uphold the ruling of the lower court,” he said.

Snow said the case concerns an attack on the adult industry.

According to court documents, the state argues that the adult business provisions did not change the bill’s original purpose, which was to create new crimes and enhance the penalties on existing crimes.

House Speaker Rod Jetton, R-Marble Hill, and Sen. Matt Bartle, R-Lee’s Summit, were among the bill’s biggest backers.

Neither Jetton nor Bartle immediately returned calls seeking comment.

The case centers on whether three amendments regulating strip clubs and other adult-oriented businesses that were added to a 2005 drunken driving bill go too far.

The added provisions make it a class A misdemeanor to come within 10 feet of a semi-nude dancer and requires dancers perform on a stage at least two feet from the ground and behind a two-foot tall railing. It also bans people under 21 from the businesses.
