Plaintiff law firms Labaton Sucharow and the Thornton Law Firm are again in the spotlight after a federal judge slashed their fees in a large class action and referred his opinion about the firms’ conduct to a disciplinary authority.

Thursday’s decision by U.S. District Judge Mark Wolf of the District of Massachusetts found that New York-based Labaton and Boston-based Thornton had engaged in “serious, repeated misconduct.” Wolf issued his decision after a special master’s investigation in 2018 confirmed  that they double-counted millions of dollars’ worth of time and hid a $4.1 million payment to a lawyer who did no work on the case.
