Article 63

For the admission to official listing of debt securities which are issued by a Member State or its regional or local authorities in a physical form, it is necessary and sufficient that such physical form comply with the standards in force in that Member State. Where the physical form does not comply with the standards in force in the Member State where admission to official listing is applied for, the competent authorities of that state shall bring this situation to the attention of the public.

The physical form of debt securities issued by non-member countries or their regional or local authorities or by public international bodies must afford sufficient safeguard for the protection of the investors.
