Where a subsequent contract that is silent about arbitration entirely supersedes a prior contract that contained an arbitration clause, the arbitration clause does not survive.  Dasher v. RBC Bank (USA), 745 F.3d 1111 (11th Cir. 2014) (No. 13-10257).  The case involved a suit by bank customers complaining about excessive fees.  The customers had an account agreement with a predecessor bank that contained an arbitration clause, but their agreement with the successor bank was silent about arbitration.  Finding that the successor bank’s agreement clearly stated that it superseded all prior versions, the court concluded that the arbitration clause did not survive.
