Lawyers for media mogul Sumner Redstone on Monday asked a court to dismiss ex-girlfriend Manuela Herzer's petition for a new evaluation of the 92-year-old's mental competence, while Herzer's attorneys said they will seek a subpoena of Viacom CEO Philippe Dauman to compel his testimony in the case.
Investors are closely following the lawsuit, which has raised concerns about whether Redstone is capable of continuing as executive chairman of Viacom and CBS Corp.
The motion filed on behalf of billionaire Redstone on Monday said he need not be examined since his own physician concluded that he was making healthcare decisions for himself. Redstone's lawyers argued that the court proceeding does not appear reasonably necessary to protect Redstone's interests and called it "abusive."
Dr. Richard Gold, Redstone's primary treating physician, said in documents submitted to the court that he saw Redstone as recently as December 30 and the visit was "routine." "Mr. Redstone seemed his usual self, and joked with me," he said.
A brain scan in November "was quite good for a 92-year-old," Gold said.
Herzer petitioned in November to have Redstone examined to see if he was able to make decisions for himself. Weeks earlier, Herzer had been told to leave Redstone's Los Angeles home and was replaced by Dauman as Redstone's healthcare agent.
