When the CFPB may [issue its arbitration rule] is unknown. A spokesman told Bloomberg BNA that the bureau continues to gather information from stakeholders on the arbitration rulemaking. A final regulation is unlikely to take effect before late 2017 or 2018, Joe Olson, a partner and class action defense specialist with Michael Best & Friedrich LLP, told Bloomberg BNA. The 2010 Dodd Frank Act calls for a 180 day interim from final action on an arbitration rule to its effective date.
