The letter summarizes arguments that could be made for dismissing a case involving several corporate defendants. It requests permission to file supplemental briefing arguing that dismissal remains warranted based on forum non conveniens even with greater deference to plaintiffs' choice of forum, as directed by the appeals court. It also notes there are additional grounds for dismissing some or all claims, such as failure to state a claim or satisfy pleading standards. For example, arbitration may be compelled for claims against Western Union by plaintiffs who agreed to arbitration terms for money transfers. The letter requests permission to file pre-motion letters on these other arguments.
