Article 23 - Proceedings

1. Proceedings relating to measures taken under this Convention by the requested State shall be brought only before the appropriate body of that State.

2. Proceedings relating to measures taken under this Convention by the applicant State, in particular those which, in the field of recovery, concern the existence or the amount of the tax claim or the instrument permitting its enforcement, shall be brought only before the appropriate body of that State. If such proceedings are brought, the applicant State shall inform the requested State which shall suspend the procedure pending the decision of the body in question. However, the requested State shall, if asked by the applicant State, take measures of conservancy to safeguard recovery. The requested State can also be informed of such proceedings by any interested person. Upon receipt of such information the requested State shall consult on the matter, if necessary, with the applicant State.

3. As soon as a final decision in the proceedings has been given, the requested State or the applicant State, as the case may be, shall notify the other State of the decision and the implications which it has for the request for assistance.
