One of the cases Ratzinger pursued involved Father Marcial Maciel Degollado, a Mexican priest and founder of the Legion of Christ, who had been accused repeatedly of sexual abuse. Biographer Andrea Tornielli suggested that Cardinal Ratzinger had wanted to take action against Maciel Degollado, but that John Paul II and other high-ranking officials, including several cardinals and notably the Pope's influential secretary Stanisław Dziwisz, prevented him from doing so. According to Jason Berry, Angelo Sodano "pressured" Cardinal Ratzinger, who was "operating on the assumption that the charges were not justified", to halt the proceedings against Maciel in 1999. When Maciel was honored by the Pope in 2004, new accusers came forward and Cardinal Ratzinger "took it on himself to authorize an investigation of Maciel". After Ratzinger became pope he began proceedings against Maciel and the Legion of Christ that forced Maciel out of active service in the Church. On 1 May 2010, the Vatican issued a statement denouncing Maciel's "very serious and objectively immoral acts", which were "confirmed by incontrovertible testimonies" and represent "true crimes and manifest a life without scruples or authentic religious sentiment." Benedict also said he would appoint a special commission to examine the Legionaries' constitution and open an investigation into its lay affiliate Regnum Christi. Cardinal Christoph Schönborn explained that Ratzinger "made entirely clear efforts not to cover things up but to tackle and investigate them. This was not always met with approval in the Vatican". According to Schönborn, Cardinal Ratzinger had pressed John Paul II to investigate Hans Hermann Groër, an Austrian cardinal and friend of John Paul accused of sexual abuse, resulting in Groër's resignation.
