Sign, sign, everywhere a sign.
Well, only for 30 days after an event in Washington, D.C.
That's the gist of a ruling by the U.S. Circuit Court of Appeals for the District of Columbia after two activist groups claimed the district's sign law violated the First Amendment. The ordinance allows signs to be posted on lampposts for up to 180 days, except that event signs must be removed at least 30 days after an event.
The federal appeals court acknowledged that the law may favor non-event signs, but it does not violate free speech rights. The court reversed a trial judge's decision in the case and vacated a sanctions award against the defendant.
