45 Surrender by consent
(1) A person may at any time notify the District Court that he or she consents to being surrendered to the ICC for the international crime or crimes for which surrender is sought.
3. A person who is provisionally arrested may be released from custody if the requested State has not received the request for surrender and the documents supporting the request as specified in article 91 within the time limits specified in the Rules of Procedure and Evidence. However, the person may consent to surrender before the expiration of this period if permitted by the law of the requested State. In such a case, the requested State shall proceed to surrender the person to the Court as soon as possible.
