LOS ANGELES — A California appeals court on Friday revived lawsuits from two men who allege Michael Jackson sexually abused them for years when they were boys. A three-judge panel from California’s 2nd District Court of Appeal found that the lawsuits of Wade Robson and James Safechuck should not have been dismissed by a lower court, and that the men can validly claim that the two Jackson-owned corporations that were named as defendants in the cases had a responsibility to protect them.
