Ask a Lawyer and Get Answers to Your Legal Questions
I do not know what the judge has done, so I can only answer in general. Feel free to reply on this question thread and provide more details if you think it appropriate.
You can have your attorney file a motion to ask the judge to recuse himself on the basis that he's not applying the law correctly/fairly. The difficulty with this course of action is that the person who gets to decide on such a motion is the judge himself. As you may imagine, judges are for the most part incapable of or unwilling to admit on papers that they cannot apply the law fairly as written or that they cannot be impartial. Filing such a motion, therefore, is unlikely to succeed and can further alienate the judge.
Your lawyer may be able to get leave to re-argue issues the judge decided incorrectly. You would need to speak to your lawyer about that. You could also file a complaint with the judiciary committee against the judge to have the judge investigated. Judges have bosses too, and they are held accountable for their actions, just as other employees are. You should not do this, however, without first running it by your lawyer.
Just checking in to see if you need more help or any clarification of my answer. If so, please reply here on this question thread.
