At the Legion of Christ seminary in Rome, Fr. Maciel is reported to have molested about 30 of the boys in his charge during the 1950s, often telling them that he had a special dispensation from Pope Pius XII to do so. Eight of his former students — a retired priest, three professors, a lawyer, a rancher, an engineer, and a teacher, now all in their 60s — have submitted to the Vatican sworn affidavits documenting their abuse at the hands of Fr. Maciel. But when the victims filed suit under Canon Law to have Fr. Maciel excommunicated, Cardinal Ratzinger intervened to halt the proceedings, without any investigation of the allegations whatsoever. According to Brian Ross of ABC News, when he tried to question Ratzinger about this episode a few years ago, he refused to discuss the matter, “became visibly upset and actually slapped this reporter’s hand”!

The charges against Fr. Maciel involve nine men (one now dead), all former Legionaries. For some, the alleged abuse began when they were barely 12 years of age, and continued until the men were in their mid-20s. Much of the abuse took place in Mexico, Spain, and Italy. Two of the men, Mexican Fr. Juan Vaca and Spanish Fr. Félix Alarcón, served the Legion in America. Fr. Alarcón opened the Legion of Christ center in Connecticut in 1965 and Fr. Vaca served for five years as the U.S. Legion Director before leaving the order. Three of the nine filed a canonical suit against Maciel and have been waiting years for it to be heard.
So you were on the right track, though that excerpt you posted inflated things, not surprisingly.
