Article 6

1. The Commission shall ensure that each project, scheme or measure is implemented in accordance with this Regulation, with the provisions adopted for its application and with the Regulation adopted pursuant to Article 209 of the Treaty.

To this end, each of the Member States concerned shall supply the Commission with all information requested by it and shall take all steps with regard to Community-assisted projects, schemes or measures to facilitate such supervision as the Commission may consider appropriate, including on-the-spot checks made at its request with the approval of the Member State concerned by the latter's competent authorities, in which Commission officials may participate. Each Member State concerned shall make available to the Commission, for a period of three years from the transfer of the balance referred to in Article 5 (3), all supporting documents or certified copies thereof relating to expenditure.

2. Where a project, scheme or measure is not implemented in conformity with this Regulation or departs substantially from decisions taken for its application, the Commission may suspend payments still due. In this case, it may decide that sums already paid or still due are to be allocated, in accordance with the procedure laid down in Article 8, to other projects, schemes or measures submitted under this Regulation. If, in the opinion of the Commission, no other project, scheme or measure is available, it shall recover the payments made.
