(Reuters) - A shareholder filed a lawsuit against Viacom's (VIAB.O) board on Tuesday, alleging the company and CBS (CBS.N) improperly paid millions to executive chairman Sumner Redstone "while he was physically and mentally incapacitated."
Questions about Redstone's health were heightened in November after a former girlfriend filed a lawsuit that raised doubts about the billionaire's competence.
The new lawsuit, filed in Delaware Court of Chancery, says payments to Redstone "for services not rendered" amounted to bad faith by Viacom's board. It also says the board misrepresented Redstone's deteriorated physical and mental condition in a January 2015 proxy statement.
