Sorry, I’m not understanding you. I’m talking about recusal from hearing a case, not from the correct decision IN a case. A judge whose impartiality might reasonably questioned, such as by his/her having previously publicly stated a personal opinion on the underlying issue, must self-recuse, e.g., Kagan’s email to Larry Tribe celebrating the passage of Obamacare.
But aren't the comments that this guy is whining about precisely about the non-uniform application of such laws? And it's ridiculous to say that any statement made outlining a [political] opinion should result in the need to recuse on that topic.
