Thank you for the new question.
If this matter has been settled in the court already, he cannot bring it up again in the new case and neither can you, it is called "res judicata" or "already decided" which is why the court said they did not want to hear it.
You cannot at this point, since the case is over, force him to disclose the truth about the price. Furthermore, it is now irrelevant as you won your judgment, whatever the amount is. Since you never appealed that judgment, it is over and done. You can ask your attorney about it again and tell him this guy is claiming he got information from your attorney, which could also be a lie, but this is really not relevant to your case at hand and the boat case from you are saying is a dead issue and the judge will not waive the statute of limitations over that issue I am afraid.
