CHAPTER FIVE
INTERNATIONAL LEGAL ASSISTANCE
Division Three
Requests by foreign authorities
Section 539
Authorisation of assistance by court
(2) If the assistance shall be provided on the basis of foreign legal provisions, the judge shall decide upon a motion by the prosecutor whether the foreign procedure does not conflict with the interests protected by the provisions of Article 481. If he does not find such a conflict he shall authorise the provision of the assistance and shall at the same time decide how the evidence shall be taken. An appeal by the prosecutor, with a postponing effect, shall be admissible against the court’s decision. The decision of the court on contradiction of procedure under foreign provision is not required if it concerns delivery of a document or instruction of a person under foreign provision.
Refusal of ICC request
Conflict with existing fundamental legal principle of general application - consultations with the Court
