OPINION: These consolidated proceedings involve a broad attack on the arbitration program established by The Permanente Medical Group, Inc., Kaiser Foundation Hospitals, and Kaiser Foundation Health Plan, Inc. (collectively, hereinafter, Kaiser or appellants) for medical malpractice claims. In appeal No. A062642, Kaiser seeks review of an order by which the Alameda County Superior Court denied its petition to compel arbitration of the claims asserted by respondents, who are members of the family and representatives of the estate of Wilfredo Engalla (collectively, hereinafter, the Engallas or respondents), a Kaiser patient who died of lung cancer in October 1991. n1 The trial court refused to enforce an arbitration provision contained in the group medical and hospital service agreement (the Service Agreement) under which Mr. Engalla had health care coverage, holding that Kaiser had engaged in fraud in the inducement of the arbitration provision. This decision was based on findings that Kaiser knowingly misrepresented the speed and efficiency of its arbitration program, and that the collective bargaining agent for Mr. Engalla's employer reasonably relied on those representations in agreeing to accept the arbitration clause in the Service Agreement. - - - - - - - - - - - - - - - - - -Footnotes- - - - - - - - - - - - - - - - - - n1 Initially, appellants asserted only claims for professional negligence based on an alleged failure of Kaiser medical personnel to diagnose Mr. Engalla's cancer sooner, and loss of consortium and support by his wife and children, respectively. After submitting these claims for arbitration--and becoming frustrated by delays in the process--appellants filed a court action alleging claims of professional negligence, breach of contract, fraud, breach of the covenant of good faith and fair dealing, and abuse of process. - - - - - - - - - - - - - - - - -End Footnotes- - - - - - - - - - - - - - - - - The trial court also found that Kaiser and its lawyers committed fraud "in the specific application" of the arbitration provision by engaging in dilatory behavior while defending against the Engallas' claims in the arbitration proceeding that was abandoned after Mr. Engalla died. Apparently, the trial court accepted respondents' argument that Kaiser was engaging in delaying tactics in order to minimize its exposure for noneconomic damages to Mr. and Mrs. Engalla. Finally, the trial court found that the Kaiser arbitration program is oppressive and unconscionable as currently structured, and that it would be inequitable to require the Engallas to arbitrate their claims in such a "corrupt" forum. In two related writ proceedings, Nos. A063427 and A063547, Kaiser and its attorneys seek a writ of mandate directing the superior court to vacate its order compelling disclosure of 14 documents on the ground that they fell within the "fraud exception" to the attorney-client privilege. The Engallas cross-appeal from this discovery order, arguing that, by partially disclosing many details about the adoption and operation of its arbitration program, Kaiser has waived any applicable privilege or work product protections for all documents relating to its arbitration program. The Engallas further contend that Kaiser had a fiduciary duty to fully apprise its patients of the procedures in use and the implications of accepting the terms of the arbitration program, which duty was breached by both inaccurate and incomplete disclosures in its arbitration materials. They claim, therefore, the trial court order did not go far enough to require disclosure of attorney-client communications and work product generated by Kaiser lawyers on the subject of its arbitration program. We conclude that: (1) the trial court's finding of fraud in the inducement of the arbitration provision is not supported by substantial evidence; (2) the Engallas' claim of "fraud in the application" of the arbitration provision must be submitted to the arbitrator; (3) the trial court's finding that the Kaiser arbitration program is oppressive and unconscionable as currently structured and administered is not supported by substantial evidence; (4) all of the Engallas' claims--including their causes of action for professional negligence, fraud, breach of contract, breach of the covenant of good faith and fair dealing, and abuse of process-- are arbitrable; and (5) the trial court erred by refusing to enforce the arbitration provision in the Service Agreement. Accordingly, we reverse the decision of the trial court and remand with directions to enter an order granting appellants' petition to compel arbitration of the claims asserted in the Engallas' complaint. In light of our ruling on the enforceability of the arbitration provision, we vacate the trial court's order compelling disclosure of certain attorney-client communications and attorney work product, but do so without prejudice to respondents' right to renew their motion before the neutral arbitrator, to the extent those materials--as well as others that were sought but not ordered disclosed--are relevant to respondents' remaining claims.
