(3) To the extent that consultations with the Court or notifications to the Court are foreseen in the Rome Statute or this law, para. 1 sentence 1 applies mutatis mutandis. If an office other than the office responsible in sentence 1 becomes aware of acts that under the Rome Statute or this law that makes consultations with or notifications to the Court necessary, that office shall promptly inform the office responsible pursuant to sentence 1 for the leadership of the consultation. To the extent there are certain circumstances of which the Court should be informed or its decision or agreement to be obtained, the office responsible pursuant to sentence 1 shall take the necessary steps therefore. In urgent matters, the office first aware of the circumstances creating a duty of notification or the acts making a decision or agreement of the Court necessary, shall inform the Court of the circumstances or acts beforehand.
2. Where the person sought for surrender brings a challenge before a national court on the basis of the principle of ne bis in idem as provided in article 20, the requested State shall immediately consult with the Court to determine if there has been a relevant ruling on admissibility. If the case is admissible, the requested State shall proceed with the execution of the request. If an admissibility ruling is pending, the requested State may postpone the execution of the request for surrender of the person until the Court makes a determination on admissibility.
4. If the person sought is being proceeded against or is serving a sentence in the requested State for a crime different from that for which surrender to the Court is sought, the requested State, after making its decision to grant the request, shall consult with the Court.
4. Upon the request of the Court, a State Party shall consult with the Court, either generally or with respect to a specific matter, regarding any requirements under its national law that may apply under paragraph 2 (c). During the consultations, the State Party shall advise the Court of the specific requirements of its national law.
3. Where execution of a particular measure of assistance detailed in a request presented under paragraph 1, is prohibited in the requested State on the basis of an existing fundamental legal principle of general application, the requested State shall promptly consult with the Court to try to resolve the matter. In the consultations, consideration should be given to whether the assistance can be rendered in another manner or subject to conditions. If after consultations the matter cannot be resolved, the Court shall modify the request as necessary.
(i) In the event that a State Party receives competing requests, other than for surrender or extradition, from the Court and from another State pursuant to an international obligation, the State Party shall endeavour, in consultation with the Court and the other State, to meet both requests, if necessary by postponing or attaching conditions to one or the other request.
3. Upon the request of the Court, a State Party shall consult with the Court, either generally or with respect to a specific matter, regarding any requirements under its national law that may apply under paragraph 2 (e). During the consultations, the State Party shall advise the Court of the specific requirements of its national law.
Where a State Party receives a request under this Part in relation to which it identifies problems which may impede or prevent the execution of the request, that State shall consult with the Court without delay in order to resolve the matter. Such problems may include, inter alia:
(b) In the case of a request for surrender, the fact that despite best efforts, the person sought cannot be located or that the investigation conducted has determined that the person in the requested State is clearly not the person named in the warrant; or
