I'm surprised arbitration holds up. I can believe the court say it comes first and the reasoning of arbitration should be given to the jury along with instructions that they can disbar a lawyer who tries to reverse something the arbitration decides when arbitration was correct, but ultimately the right to a jury trial is required.
