Judicial co-operation paras 7.12 to 7.13
7.12 If the United Kingdom receives a formal request from an overseas court or other prosecuting authority that appears to have a function of making requests for legal assistance, the Secretary of State (in Scotland the Lord Advocate) will consider the request under the Crime (International Co-operation) Act 2003. In order to assist he must be satisfied that the request is made in connection with criminal proceedings or a criminal investigation being carried on outside the United Kingdom.
7.13 If such a request is accepted, that request will be passed to a nominated court in the United Kingdom. That court may make an order requiring a CSP to disclose the relevant information to the court for onward transmission to the overseas authority.
