Section 11 is concerned with the use of information lawfully obtained by any member of a joint investigation team which is not otherwise available to the competent authorities of the member states that established the team. Such information can only be used for the purposes for which the team was established. It may be used in other circumstances, but only where the prior consent of the member state in which such information became available has been obtained or where the member state has been informed. Consent to use of the information for the detection, investigation and prosecution of criminal offences other than those in respect of which the team was established may be withheld where it would be likely to prejudice criminal investigations being conducted in the State or where a request for mutual assistance or co-operation could be refused under the international co-operation provisions of the Criminal Justice Act 1994.
