Article 64

Without prejudice to any more favourable provisions of national laws, persons domiciled in a Member State who are being prosecuted in the criminal courts of another Member State of which they are not nationals for an offence which was not intentionally committed may be defended by persons qualified to do so, even if they do not appear in person. However, the court seised of the matter may order appearance in person; in the case of failure to appear, a judgment given in the civil action without the person concerned having had the opportunity to arrange for his defence need not be recognised or enforced in the other Member States.
