Florida’s Judicial Ethics Advisory Committee came out with a guideline on whether judges can “friend” lawyers who are appearing in cases before them. According to the Committee, it isn’t permissible since it creates the impression that the “friended” lawyer is in a position to influence the judge.
Of course, most people’s facebook friend list is comprised mostly of people who you’ve barely spoken with recently, never mind having any influence over. Luckily, judges can still make friends on facebook… lawyers can still become their fans, as long as the judge can’t say no to their request.
The guideline is available here.
