The rights and obligations arising from agreements concluded before 1 January 1958 or, for acceding States, before the date of their accession, between one or more Member States on the one hand, and one or more third countries on the other, shall not be affected by the Constitution.

To the extent that such agreements are not compatible with the Constitution, the Member State or States concerned shall take all appropriate steps to eliminate the incompatibilities established. Member States shall, where necessary, assist each other to this end and shall, where appropriate, adopt a common attitude.

In applying the agreements referred to in the first paragraph, Member States shall take into account the fact that the advantages accorded under the Constitution by each Member State form an integral part of the Union and are thereby inseparably linked with the creation of institutions on which powers have been conferred by the Constitution and the granting of identical advantages by all the other Member States.
