Second, even if the mediator chose not to inform the court/JW of how things went in a informal fashion, and used all available time to prepare/submit his formal report, there is nothing stopping any litigant from issuing a PR about a success/settlement in mediation if the contracts have been executed by proper authority.

Confidentiality. All mediation proceedings, including statements by any party, attorney, or other participant, are confidential. The proceedings may not be recorded, reported, placed in evidence, or made known to the judge or jury. A party is not bound by anything said or done at the mediation conference unless a settlement is reached.

Be well
