REUTERS/Andrew Kelly/File Photo Acquire Licensing RightsNov 27 (Reuters) - A U.S. appeals court on Monday handed 3M (MMM.N), Corteva Inc (CTVA.N) subsidiary E.I. Circuit Court of Appeals vacated a lower court's approval of the massive class action, which included virtually every resident of Ohio and put considerable legal pressure on the chemical manufacturers to settle the plaintiffs' claims. The appeals court instructed the lower court to dismiss Hardwick's lawsuit, which had aimed to force the companies to pay for studies analyzing the health impacts of PFAS. The lawsuit also sought to establish a fund to monitor Ohio residents for health impacts from PFAS exposure. The chemicals are often referred to as forever chemicals because they do not easily break down in nature or in the human body.
