SECTION II: DETENTION PENDING SURRENDER AND SEIZURE
Art. 20 Detention pending surrender
1 Detention pending surrender generally shall be maintained throughout the proceedings.
2 Detention may exceptionally be lifted at any stage of the proceedings if it appears justified under the circumstances. The person may at any time submit an application for interim release. Before reaching a decision, the Central Authority shall inform the Court and give full consideration to the Court’s recommendations. The decision of the Central Authority may be appealed within ten days of written presentation of the decision; appeals must be lodged with the Federal Supreme Court. Articles 214 et seq. of the Federal Law of 15 June 1934 on Federal Criminal Procedure shall apply by analogy.
3 If the person already is being held in pre-trial detention or is serving a prison sentence, the warrant for detention pending surrender shall have the following effects in particular, subject to other instructions of the Court:
a. Without approval of the Central Authority, the person may neither be released nor deported from Switzerland.
b. Approval of the Central Authority shall be necessary for alleviation of the conditions of detention.
c. Visitation rights may only be granted and correspondence may only be censored in agreement with the Central Authority
