The Delaware Court of Chancery on Thursday ruled the CBS Corp. board must face claims it improperly approved millions of dollars in payments to Sumner Redstone after the company’s former executive chairman became incapacitated in 2014.

Chancellor Andre G. Bouchard said CBS investor R.A. Feuer could proceed with a derivative lawsuit alleging that the CBS board members had committed corporate waste by deciding to continue the annual payments, even after the 94-year-old’s health had deteriorated to the point where he could no longer provide any meaningful services to the company.
