103.This section implements Article 3 of the 2001 Protocol for the purpose of outgoing requests from the UK to other participating countries to monitor transactions conducted on a specified account or accounts. Subsection (1) provides that an application may be made to a judicial authority (as defined in subsection (2)) to request assistance under this section if it appears relevant to a UK investigation into criminal conduct. A prosecuting authority designated by order made by the Secretary of State (or, in relation to Scotland, the Lord Advocate or procurator fiscal) may itself request assistance under subsection (3).
