Bloomberg: A former girlfriend and confidante of Sumner Redstone won’t get a new trial to argue the 93-year-old media billionaire was mentally incompetent when he evicted her from his mansion last year and replaced her as his health-care agent. A probate court judge in Los Angeles Monday denied Manuela Herzer’s request for a new trial. The same judge in May dismissed Herzer’s case, finding that Redstone’s videotaped deposition made it clear he didn’t want her in his life any longer.
