All ADR proceedings shall be confidential and any memoranda submitted to the ADR Specialist, any statements made during the ADR and any notes or other materials made by the ADR Specialist or any party in connection with the ADR shall not be subject to discovery or introduced into evidence in any proceeding and shall not be construed to be a waiver of any otherwise applicable privilege. Nothing in this section shall limit the discovery or use as evidence of documents that would have otherwise been discoverable or admissible as evidence but for the use of such documents in the ADR proceeding.
