In the Internet arena, "liking" a Facebook page is protected speech that's equivalent to sticking a political campaign sign in your front yard, a federal appeals court in Virginia said Wednesday in a closely watched First Amendment retaliation case.

A three-judge panel of the U.S. Court of Appeals for the Fourth Circuit overturned a trial judge who concluded that the act of "liking" a Facebook page does not come with constitutional protection. The appeals court revived certain claims in a suit against a Virginia sheriff who didn't reappoint a group of employees who supported a rival candidate for office.
