In the civil context, DOJ has the legislative authority to do so, but only pursuant to an IAEAA Agreement with the requesting jurisdiction. There is one agreement with such a provision, between the U.S. and Australia. It is contemplated pursuant to the MMAC model agreement.   In the criminal context, the central authority under MLATs and letters rogatory is the Office of International Affairs (CRM OIA) in the Criminal Division of Department of Justice, which renders a broad array of assistance.  Such requests usually seek corporate documents and, less frequently, witness interviews.  Additionally, a limited number of criminal MLAT treaties that the US is a signatory to allow for assistance to be provided to countries conducting civil or administrative proceedings if those proceedings will lead to a referral for criminal prosecution in the requesting jurisdiction.
