Each self-regulatory organization which has members who are registered as leverage transaction merchants must be able to demonstrate its capability to promulgate rules and to conduct proceedings which provide a fair, equitable and expeditious procedure, through arbitration or otherwise, for the voluntary settlement of a leverage customer's claim or grievance brought against any member leverage transaction merchant or any employee of a member leverage transaction merchant. Such rules shall be consistent with the rules set forth in part 180 of this chapter governing contract market arbitration and dispute settlement procedures.
