You are a defense attorney who sees a judge in your jurisdiction having dinner with a prosecutor. Both are married to other people. You happen to have a case in front of this judge, and the prosecutor is your opponent. You consider that you could request the judge recuse himself from the case, but this may animosity, and if he refuses, it could be detrimental to your client. Alternatively, you could keep quiet and use the information on appeal, but this may mean your client spends years in prison. Finally, you could do nothing and hope that the judge is not biased toward the prosecution in his rulings. What would you do?
