CAT/C/VAT/CO/1 (d) Ensure that all State party officials exercise due diligence and react properly to credible allegations of abuse, subjecting any official that fails to do so to meaningful sanctions; (e) Take effective measures to ensure that allegations received by its officials concerning violations of the Convention are communicated to the proper civil authorities to facilitate their investigation and prosecution of alleged perpetrators. The State party should provide data to the Committee in its next periodic report on the number of cases in which it provided information to civil authorities both in the places where cases arose and in the places where the persons concerned are currently located. Impunity 13. The Committee appreciates the confirmation provided regarding the ongoing investigation under the Vatican City State Criminal Code of allegations of sexual abuse of minors by Archbishop Josef Wesolowski, former papal nuncio to the Dominican Republic. The Committee notes that the Republic of Poland has reportedly requested the extradition of Archbishop Wesolowski. The Committee also is concerned that the State party did not identify any case to date in which it has prosecuted an individual responsible for the commission of or complicity or participation in a violation of the Convention (arts. 4, 5, 6, 7 and 8). The State party should ensure that its competent authorities proceed to a prompt and impartial investigation of Archbishop Wesolowski and any other persons accused of perpetrating or being complicit in violations of the Convention who are nationals of the State party or are present on the territory of the State party. If warranted, the State party should ensure such persons are criminally prosecuted or extradited for prosecution by the civil authorities of another State party. The Committee requests the State party to provide it with information on the outcome of the investigation concerning Archbishop Wesolowski. Cooperation with civil and criminal proceedings 14. The Committee is concerned by reports it has received of cases in which the State party has declined to provide information to civil authorities in connection with proceedings relating to allegations that clergy members committed violations of the Convention, despite the fact that since 2001 the Congregation for the Doctrine of the Faith in the Vatican City State has had responsibility for receiving and investigating all allegations of sexual abuse of minors by Catholic clergy. The Committee expresses concern about allegations that in 2013 the papal nuncio to Australia invoked diplomatic immunity in refusing to provide archival documentation to assist the New South Wales Special Commission of Inquiry into sex abuse. The Committee recalls that article 9 of the Convention obligates States parties to “afford one another the greatest measure of assistance” in connection with criminal proceedings related to violations of the Convention, “including the supply of all evidence at their disposal necessary for the proceedings” (art. 9). The State party should take effective steps to ensure the provision of information to civil authorities in cases where they are carrying out criminal investigations of allegations of violations of the Convention perpetrated by Catholic clergy or acquiesced to by them. The State party should ensure the procedures for requesting such cooperation are clear and well-known to the civil authorities and that requests for cooperation are responded to promptly. 5
