A top Swiss court on Monday rejected an appeal by the Vatican's bank to keep secret information from one of its Swiss bank accounts suspected of being used for fraud.
Judges at Switzerland's federal criminal court allowed the transfer of most information sought by prosecutors in Italy from the account held by the Vatican bank, officially known as the Institute for Religious Works (IOR), the daily Le Temps reported.
Italian prosecutors suspect the account was used in 2007 and 2008 by third parties to launder as a donation funds from the sale of a company.
The IOR had invoked the Vatican's sovereign immunity, but the judges found that the transactions in question did not relate to functions covered by that immunity.
However, Swiss judges ruled that information not pertinent to the investigation would not be transferred.
Under pressure from its international partners, in particular the United States, Switzerland has been gradually dismantling its decades-old tradition of banking secrecy.
