Via The New York Times:
The Supreme Court on Thursday unanimously ruled that an Arizona town had violated the First Amendment by placing limits on the size of signs announcing church services.
The case, Reed v. Town of Gilbert, No. 13-502, concerned an ordinance in Gilbert, Ariz., that has differing restrictions on political, ideological and directional signs. It was challenged by a church and its pastor.
The ordinance set limits on the dimensions of various kinds of temporary signs based on the messages they conveyed.
Political signs, concerning candidates and elections, were permitted to be as large as 32 square feet, were allowed to stay in place for months and were generally unlimited in number. Ideological signs, about issues more generally, were not permitted to be larger than 20 square feet, could stay in place indefinitely and were unlimited in number.
