Article 9

If an importing Contracting State or one of its authorised assay offices has reason to believe that an assay office in an exporting Contracting State has affixed the Common Control Mark without having complied with the relevant provisions of this Convention, the assay office by which the articles are purported to have been marked shall be immediately consulted and shall promptly lend all reasonable assistance for the investigation of the case. If no satisfactory settlement is reached, either of the parties may refer the case to the Standing Committee by notifying its Chairman. In such a case the Chairman shall convene a meeting of the Standing Committee.

If any matter has been referred to the Standing Committee under paragraph 1, the Standing Committee may, after having given an opportunity for the parties concerned to be heard, make recommendations as to the appropriate action to be taken.

If within a reasonable time a recommendation referred to in paragraph 2 has not been complied with, or the Standing Committee has failed to make any recommendation, the importing Contracting State may then introduce such additional surveillance of articles of precious metals marked by that particular assay office and entering its territory, as it considers necessary, including the right temporarily to refuse to accept such articles. Such measures shall immediately be notified to all Contracting States and shall be reviewed from time to time by the Standing Committee.

Where there is evidence of repeated and grave misapplication of the Common Control Mark the importing Contracting State may temporarily refuse to accept articles bearing the assay office mark of the assay office concerned whether or not controlled and marked in accordance with this Convention. In such a case the importing Contracting State shall immediately notify all other Contracting States and the Standing Committee shall meet within one month to consider the matter.
