Dozens of law firms have signed an amicus brief urging the Sixth Circuit Court of Appeals to reverse a decision related to FirstEnergy's shareholder litigation. The firms argue that the ruling, which states that neither attorney-client privilege nor the work-product doctrine protects documents from two internal investigations following subpoenas from the Department of Justice, poses a significant threat to these legal protections. FirstEnergy, supported by these law firms, is appealing the May 6 decision, which has been described as a 'shockwave' in the legal community.
