Following Ajamian v. CantorCO2e, LP (2012) 203 Cal.App.4th 771 and other cases, this decision holds that an arbitration clause saying that the arbitration will proceed under AAA rules is not a sufficiently clear delegation of arbitrability to effectively delegate that issue to the arbitrator if the non-drafting party is an unsophisticated employee of the drafter. Also, even a clearer delegation would not suffice when the issue is whether the claim falls within the scope of a carve-out from arbitration. And further doubt was thrown on the delegation by a severance clause that referred to a court holding the arbitration agreement or some of its provisions unenforceable. Defendant’s arbitration agreement clearly excluded from arbitration all PAGA claims, including Mondragon’s “individual” PAGA claims.
