Article 24
Within a period of 24 hours from the moment of receipt of such ruling the accused person and his/her Defence Counsel may appeal against the ruling referred to in paragraph 2 of this Article, which shall be addressed by the competent Chamber.
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.
