Article 70(1) of Council Regulation (EEC) No 2913/92 must be interpreted as meaning that, since it applies only to goods covered by ‘a [single] declaration' where those goods are examined by the customs authorities before those authorities grant the release of those goods, that provision does not permit those authorities, in a case such as that in the main proceedings, to apply the results of the partial examination of goods covered by a customs declaration to goods covered by earlier customs declarations which have already been released by those authorities. However, Article 78 of that Code is to be interpreted as meaning that it permits the customs authorities to apply the results of a partial examination of goods covered by a customs declaration, carried out by way of sampling of them, to goods covered by earlier customs declarations submitted by the same customs declarant, which were not and can no longer be examined since the release has been granted, where those goods are identical, which it is for the referring court to ascertain.
