The Supreme Court has rejected a free-speech appeal from guides in New Orleans who object to having to be licensed to lead tours.

The justices did not comment Monday in leaving in place lower court rulings that said the licensing requirements do not violate the First Amendment.

Opponents of the requirements had hoped that the New Orleans case might attract the Supreme Court's interest because a District of Columbia court has held that similar rules in the nation's capital were unfounded.

The case is Kagan v. New Orleans, 14-585.
