Participants taking part in a Massachusetts court hearing Tuesday hope to determine whether Sumner Redstone is mentally competent and can control his $40 billion media empire.
The hearing is related to a lawsuit filed by Viacom CEO Phillipe Dauman and fellow Viacom board member George Abrams to contest their removal as trustees of the trust that will control Viacom and CBS after Redstone dies or is declared incapacitated. Redstone sought their removal two weeks ago.
Redstone’s attorneys told the court in filings the 93-year-old had “legal mental capacity” to make the changes to his trust, reported the Los Angeles Times.
Dauman and Abrams believe Redstone is being controlled by his long-estranged daughter Shari.
Dauman, Abrahams and Redstone’s granddaughter Keryn last week said they have not been allowed to see her grandfather for weeks.
