The Delaware Supreme Court has upheld the dismissal of a derivative suit challenging more than $13 million in payments the Viacom Inc. board made to founder and former chairman Sumner Redstone, even as the billionaire media mogul’s declining health prevented him from providing any services of value to the company.

The high court’s ruling, published in a two-sentence order on Friday, came just two days after lawyers for Viacom shareholder R.A. Feuer asked a three-justice panel in Dover to overturn a Delaware Court of Chancery judge’s decision in October, which found the suit was barred by the broad terms of a settlement in separate litigation releasing Viacom’s board members of “any and all” claims predating the August 2016 agreement.
