JM 9-13.512
When a country provides evidence pursuant to a request for legal assistance, such as an MLAT, letter rogatory, or letter of request, contact OIA before using or disclosing it for a purpose other than that specified in the legal assistance request. (Examples of such use or disclosure include Freedom of Information Act requests, or requests to use the evidence in a parallel civil or administrative proceeding.) OIA will work with the USAO to determine whether the evidence can be used for a different purpose without the express permission of the country that provided it and, if not, for guidance in securing such permission.
