If a judge follows you on Twitter, must he recuse himself from any future cases where you are a party or an attorney? Surely reading tweets doesn't amount to an appearance of bias.
What about a LinkedIn connection? It is, after all, the "professional" social network.
Or what about Facebook? Of all the social networks, it is the most informal. Friendship gives you access to photos, wall postings, and other non-public information. If a judge is Facebook friends with a litigant, or an attorney, does that mandate recusal?
We've discussed the issue before, and have seen it pop up in state cases, but this petition for certiorari, set for consideration on April 25, asks the U.S. Supreme Court to set a nationwide standard for social media and the appearance of impropriety. It's a tall order for a Court that still uses ivory paper instead of email.
