A former consumer of Debevoise & Plimpton, who’s at present going through a number of U.S. Securities and Trade Fee investigations and sought asylum in Russia, is suing the agency and three attorneys who labored on his case, alleging that they coated up a key mistake in his protection with a view to protect their very own reputations.
