Looking at the Civil Practice Law and Rules I do not find any rule that states that a hearing is "required" for an order to show cause to be considered.
This might be where you have difficulty here, because if there is no hearing required at all, then what the judge did was to NOT have a hearing, and to decide based upon just the papers, which i believe is what was stated in the decision, correct?
It certainly doesn't sound like you are being treated very fairly, but to be honest I don't think you have recourse in this instance. The judge decided on the papers, so what happened in court that day wasn't on the record.
Your option is to appeal, but you will need to have a basis for that appeal based upon the papers, not based upon what the judge did.
You can also make a motion to have the judge removed from the case. This is a VERY tricky thing, and I have seen it go very wrong for people. It doesn't happen often and only if there is a severe conflict of interest. In the end , the judge is the judge and it is his courtroom, so as long as he isn't going extremely outside of some written rules, there is not much you can do.
I hope this was helpful and good luck to you.
