Battle over Redstone's media empire takes another turn

Lawyers for Redstone are seeking to remove two members of the board of the trust that will eventually control Redstone's media empire, which includes CBS Corp. and Viacom Inc.

In his statement, Tu, a lawyer with the Los Angeles law firm Orrick, Herrington & Sutcliffe, said that Dauman and Abrams had also been removed as directors of National Amusements Inc., the holding company that owns the controlling shares of cable giant Viacom and CBS.

"The picture is quite clear, Mr. Redstone is being manipulated and used by his daughter in an attempt to accomplish her long-held goal, which Mr. Redstone has always opposed, of gaining control of National Amusements and Viacom," the Viacom statement said.

Herzer's lawyer said outside of court that his client would file a new suit against Shari Redstone for at least $70 million, contending the daughter had interfered with Herzer's expected inheritance and had set up a spy network of her father's nurses to help her dislodge Herzer from Sumner Redstone's life.
