"One of the most important ethical decisions facing a judge is when to recuse himself or herself from sitting in a case. Supreme Court justices fairly regularly step aside in situations in which they have a personal or financial interest in the case. But, again, that is at their discretion, and generally the reasons for recusal are not made public. What's more, a decision by a Supreme Court justice not to step aside cannot be appealed."
