CHAPTER 10

External relations
Article 104
No person or undertaking concluding or renewing an agreement or contract with a third State, an international organisation or a national of a third State after 1 January 1958 or, for acceding States, after the date of their accession, may invoke that agreement or contract in order to evade the obligations imposed by this Treaty.
Each Member State shall take such measures as it considers necessary in order to communicate to the Commission, at the request of the latter, all information relating to agreements or contracts concluded after the dates referred to in the first paragraph, within the scope of this Treaty, by a person or undertaking with a third State, an international organisation or a national of a third State. The Commission may require such communication only for the purpose of verifying that such agreements or contracts do not contain clauses impeding the implementation of this Treaty.
On application by the Commission, the Court of Justice of the European Union shall give a ruling on the compatibility of such agreements or contracts with the provisions of this Treaty.
