Following Ajamian v. CantorCO2e, LP (2012) 203 Cal.App.4th 771, this decision holds that an arbitration clause calling for the arbitration of “any dispute” arising in connection with a contract does not “clearly and unmistakably” call for the arbitrator rather than a court to decide issues of arbitrability.  A provision calling for arbitration in accordance with AAA rules which themselves grant the arbitrator the authority to adjudicate his own jurisdiction did not result in a clear delegation of arbitrability issues to the arbitrator both because no copy of the AAA rules was given the unsophisticated patient who signed the arbitration form and because the arbitration clause introduced ambiguity by its severance clause referring to a court finding the arbitration agreement unenforceable.
