In matters of extradition for prosecution to a foreign State, the Italian judicial authority, when assessing the existence of serious indications of guilt as required under Article 705(1) of the Italian Code of Criminal Procedure in the absence of an extradition treaty with the requesting State, may not apply the “simplified” evidentiary regime set out in Article 16 of the United Nations Convention against Transnational Organized Crime, concluded on 15 November 2000 and implemented by Law No. 146 of 16 March 2006, since that Convention does not have the legal nature of an extradition treaty.
