Artikel 19

Arrest and detention, whether as a means of enforcement or simply as a precautionary measure, shall not, in civil or commercial matters, be employed against nationals of a Contracting State or persons habitually resident in a Contracting State in circumstances where they cannot be employed against nationals of the arresting and detaining State. Any fact which may be invoked by a national habitually resident in such State to obtain release from arrest or detention may be invoked with the same effect by a national of a Contracting State or a person habitually resident in a Contracting State even if the fact occurred abroad.
