If you are involved in a court case, you are generally not allowed to privately contact the judge about the case. "Ex parte" means one-sided. Talking privately with the judge about your case, without giving notice to the other party, is called "ex parte communication" and is generally not allowed. This ensures that the court’s process remains fair to all who are involved. There are rare exceptions -- for example, in emergencies or to protect a party from physical harm.
