Judge George Phelan of the Massachusetts Probate and Family Court has granted Viacom CEO Philippe Dauman’s request to expedite the schedule in his effort to have Chairman Emeritus Sumner Redstone declared incompetent.

The judge today scheduled a hearing for June 7 at 9 AM at the court in Canton, which is 15 miles southwest of Boston.

They want the court to rule that Redstone, who turns 93 today, was not competent to make the decision last Friday to remove them from the family trust and the board of National Amusements.

They’ve alleged that his daughter, Shari — who’s President of National Amusements and Vice Chair of Viacom and CBS — manipulated him to win control of her father’s media empire.

Redstone’s seven-member trust will control his 80% ownership stake in National Amusements when he’s deemed incapable of governing his own affairs, or passes. The theater chain owns 80% stakes in Viacom and in CBS.

Viacom says that it’s “pleased the Massachusetts court is moving forward on an expedited basis so that we can resolve this dispute as quickly as possible.”

Shari Redstone said yesterday that she’s “looking forward to an expedited dismissal of this meritless suit.”
