California Code, Code of Civil Procedure - CCP § 1775.9

(a) In the event that the parties to mediation are unable to reach a mutually acceptable agreement and any party to the mediation wishes to terminate the mediation, then the mediator shall file a statement of nonagreement. This statement shall be in a form to be developed by the Judicial Council.

(b) Upon the filing of a statement of nonagreement, the matter shall be calendared for trial, by court or jury, both as to law and fact, insofar as possible, so that the trial shall be given the same place on the active list as it had prior to mediation, or shall receive civil priority on the next setting calendar.
