The Supreme Court is refusing to invalidate Nevada laws banning newspaper advertisements that identify places where prostitution is legal.

The court refused to hear on Tuesday an appeal from two newspaper companies, the American Civil Liberties Union and a Nye County brothel called the Shady Lady Ranch.

Laws went into effect in Nevada in 1979 that prohibited brothel advertising in counties where prostitution is illegal. Prostitution is illegal in five counties, which include Las Vegas and Reno, and 10 Nevada counties authorize prostitution by local ordinance.

A federal judge said the laws were overly broad and unconstitutional, but the judgment was overturned by the 9th U.S. Circuit Court of Appeals. The Supreme Court upheld that ruling.
