A tour guide lectures visitors as she stands in front of Marie Laveau's tomb inside St. Louis Cemetery No. 1 in New Orleans, Tuesday, Jan. 27, 2015. The historic New Orleans cemetery that may have started the city's tradition of above-ground crypts will soon be off-limits to tourists on their own because of repeated vandalism among the tombs, the Roman Catholic archdiocese that owns the property has announced. Starting in March, entry to St. Louis Cemetery No. 1 and its labyrinth of mausoleums will be restricted to the relatives of the dead buried there and to tourists whose guide is registered with the Archdiocese of New Orleans.

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.
