Artikel 10

1. The Parties undertake to recognise that every person belonging to a national minority has the right to use freely and without interference his or her minority language, in private and in public, orally and in writing.
2. In areas inhabited by persons belonging to national minorities traditionally or in substantial numbers, if those persons so request and where such a request corresponds to a real need, the Parties shall endeavour to ensure, as far as possible, the conditions which would make it possible to use the minority language in relations between those persons and the administrative authorities.
3. The Parties undertake to guarantee the right of every person belonging to a national minority to be informed promptly, in a language which he or she understands, of the reasons for his or her arrest, and of the nature and cause of any accusation against him or her, and to defend himself or herself in this language, if necessary with the free assistance of an interpreter.
