In September 2011, Xenophon controversially used parliamentary privilege to accuse a Catholic priest of rape, in regard to accusations around events that occurred in the 1960s. He also accused Monsignor David Cappo and Philip Wilson, the Catholic Archbishop of Adelaide, of failing to properly investigate the allegations in 2007. All three men denied the senator's claims. Xenophon chose such action after receiving an "unsatisfactory" response from the Church when advising them of his intentions and ultimatum. Cappo subsequently stepped down from several of his public positions. Several days later, after high-level media coverage, Xenophon indicated he might not have used parliamentary privilege had he known the person he accused was about to take a period of leave.
