A defendant’s attempt to compel arbitration of class members’ claims by sending class members a new arbitration agreement after the lawsuit already was filed constituted an improper class communication; the agreement could not be used to compel arbitration.  Balasanyan v. Nordstrom, Inc., Nos. 11-cv-2609, 10-cv-2671 (S.D. Cal. Mar. 8, 2012).   After a wage and hour class action had been filed, the defendant employer sent to the class members a new dispute resolution agreement containing an arbitration clause for all past, present and future disputes.  The court found that the communication constituted an improper attempt to alter the pre-existing arbitration agreement with putative class members during litigation, and held the new agreement to be invalid and arbitration non-enforceable.
