The Vatican appeals tribunal has declared a mistrial in the Holy See’s big “trial of the century.” It’s a stunning blow to both Pope Francis’ legacy and Vatican prosecutors who had prosecuted a cardinal and several other people on alleged financial crimes. In a 16-page ruling, the appeals court ruled that Francis and Vatican prosecutors both made procedural errors that nullified the original indictment of Cardinal Angelo Becciu and required a new trial. The court set a June 22 as the date for the new trial to begin. Defense lawyers say such a ruling is enormously significant if not historic, since it amounts to a Vatican court declaring an act of the pope had no effect.
