Alan S. Kaplinsky, Chair of Ballard Spahr's Consumer Financial Services practice who uses consumer arbitration agreements with class action waivers, said of AT&T Mobility LLC v. Concepcion: "I fully expected this result, but I have to say I am thrilled. It is important to note that this opinion doesn’t mean that federal law will save an arbitration agreement that is unfair to consumers."

Mr. Kaplinsky and his partners submitted an amicus curiae brief in the case in favor of AT&T Mobility on behalf of the American Bankers Association, American Financial Services Association, Consumer Bankers Association, Financial Services Roundtable, and California Bankers Association.
