Artikel 37

1. Where a member of a force or of a civilian component or a dependent is summoned to appear before a German court or authority, the military authorities, unless military exigency requires otherwise, shall take all measures within their authority to secure his attendance provided such attendance is compulsory under German law. If the summons is not served through the liaison agency, the latter shall be informed immediately of the summons by the German court or authority, which shall give the name of the addressee and his address, as well as the time and place of the hearing or taking of evidence; this does not apply in the case of dependents if the military authorities cannot give effective support to German authorities to secure attendance.
2. Where persons whose attendance cannot be secured by the military authorities are required as witnesses or experts by a court or a military authority of a sending State, the German courts and authorities shall, in accordance with German law, secure the attendance of such persons before the court or military authority of that State.
