Convicted former media baron (and former The Jerusalem Post owner) Conrad Black is asking a judge to grant him a new trial or an acquittal, saying it "would be a miscarriage of justice to let the verdict stand." US District Judge Amy St. Eve should consider whether trial witnesses were credible, according to motions filed late Monday, more than a month after he was convicted of swindling the Hollinger International newspaper empire. "The court must consider the weight of the evidence, and must grant a new trial if that evidence preponderates heavily against the verdict, such that it would be a miscarriage of justice to let the verdict stand," the motion said. Black, who remains free on $21 million bond pending his sentencing on Nov. 30, told The Canadian Press in an e-mail Monday night that he was confident in his chances for success. "I am fine thank you, and enjoying my house in Palm Beach," he wrote. "I remain optimistic."
