Writing for the Supreme Court, Chief Justice John Roberts set a clear definition of the term "official action" and how it can be used in corruption convictions."In sum, an 'official act' is a decision or action on a 'question, matter, cause, suit, proceeding or controversy," Roberts wrote. "Setting up a meeting, talking to another official, or organizing an event (or agreeing to do so) -- without more -- does not fit that definition of an official act."Roberts also said that political corruption can still be prosecuted by the government, and noted that McDonnell's actions were "distasteful."
