Thank you for your question. I look forward to working with you to provide you the information you are seeking.
If you can make a connection between your husband and the judge's participation in the law school clinic (or even as a professor who actually taught your husband) this is grounds for you to file a motion to recuse or remove the judge for appearance of bias or conflict. You would also need to file a motion to vacate the orders or file an appeal of those orders while you were on leave.
You need to get your motion to recuse/remove filed as soon as possible and explain also how you just discovered this connection and that the judge never disclosed that connection in the beginning of the matter. It is not sufficient that the judge is a teacher at the school, you have to prove the connection to your husband directly with the judge (such as he was his professor or they had some personal interaction through the law clinic).
