2005 California Code of Civil Procedure Sections 1297.371 Article 4. Confidentiality

1297.371.  When persons agree to participate in conciliation under
this title:
   (a) Evidence of anything said or of any admission made in the
course of the conciliation is not admissible in evidence, and
disclosure of any such evidence shall not be compelled, in any civil
action in which, pursuant to law, testimony may be compelled to be
given.  However, this subdivision does not limit the admissibility of
evidence if all parties participating in conciliation consent to its
disclosure.
   (b) In the event that any such evidence is offered in
contravention of this section, the arbitration tribunal or the court
shall make any order which it considers to be appropriate to deal
with the matter, including, without limitation, orders restricting
the introduction of evidence, or dismissing the case without
prejudice.
   (c) Unless the document otherwise provides, no document prepared
for the purpose of, or in the course of, or pursuant to, the
conciliation, or any copy thereof, is admissible in evidence, and
disclosure of any such document shall not be compelled, in any
arbitration or civil action in which, pursuant to law, testimony may
be compelled to be given.
