1. Final decisions of the Office which determine the amount of costs shall be enforceable.
2. Enforcement shall be governed by the rules of civil procedure applicable in the Member State in which it takes place. Subject only to verification that the relevant document is authentic, the enforcement clause or endorsement shall be appended by the national authority appointed for that purpose by the Government of each Member State; the Governments shall inform the Office and the Court of Justice of the European Communities of the identity of each such national authority.
3. When, upon application by the party seeking enforcement, these formalities have been completed, it shall be entitled to proceed to endorsement under national law by bringing the matter directly before the competent body.
4. Enforcement shall not be suspended except by decision of the Court of Justice of the European Communities. Control as to the regularity of enforcement measures shall, however, reside with the national courts.
