Business Insider (October 21, 2015 2:34 am) -- The Public Investors Arbitration Bar Association says Finra is hiding most of its customer dispute settlements with brokers. A PIABA survey of 833 cases from January 1, 2012 to December 31, 2014 found that “expungement” was granted in 87.8% of the cases, little changed from the 2013 survey. According to PIABA, Finra should “make its national hearing officers impartial adjudicators of requests for expungement relief; “improve disclosure and raise the bar in expungement cases;” and “further improve education of arbitrators.”
