Except in certain cases, this section prohibits mediation participants other than the parties from disclosing oral and written communication made during the mediation process. Such disclosure would be inadmissible in court unless both parties agree to the disclosure in writing, the disclosure is necessary to enforce the mediation settlement, the disclosure is required by statute or regulation, or a court finds that the interest of justice outweighs the need for confidentiality. The section also would not prevent the admission of evidence used in a mediation that is otherwise discoverable elsewhere.
