| The 
				granddaughter, Keryn Redstone, argued in court papers that 
				Sumner Redstone had become a "prisoner in his own home" after 
				the former girlfriend, Manuela Herzer, was ejected from his 
				mansion in October. Herzer, 51, had sued to be reinstated as his 
				designated healthcare agent. Keryn Redstone had asked to be 
				added to the case as a co-petitioner.
 In ruling on the 34-year-old granddaughter's request, Los 
				Angeles Superior Court Judge David Cowan said, “The court 
				doesn’t believe ... her being a party truly adds anything to 
				this case."
 
 Cowan said that Keryn Redstone can testify as a witness in the 
				trial if Herzer calls her.
 
 Redstone controls a majority of the voting stock at Viacom Inc 
				and CBS Corp. Shareholders have closely followed the case for 
				what it could reveal about his mental condition.
 
 Also on Wednesday, Herzer withdrew a request for a neurologist 
				she had hired to examine Sumner Redstone. The move came after 
				the mogul's lawyers said they would not call their own 
				neurological expert as a witness.
 
 Redstone's attorneys say he was fully aware of his actions when 
				he removed Herzer as his designated healthcare agent last 
				October. Herzer argues that he lacked the mental capacity to 
				make that decision.
 
 Both sides have discussed a possible settlement but have so far 
				failed to reach an agreement. The case is scheduled to go to 
				trial on May 6.
