Article 4
Five years after the entry into force of the Convention for the Union, the Commission shall submit a report on the operation of the Rules in disputes where the Union has been acting as a respondent. On the basis of that report, the Council, on a proposal from the Commission, shall re-evaluate the reservation referred to in Article 3 and adopt a decision on the amendment or withdrawal of that reservation. If no agreement can be found in the Council, the reservation referred to in Article 3 shall remain valid, subject to periodic review every five years. The Council shall adopt a decision on the withdrawal of that reservation if all Member States conclude the Convention or when Article 47(3) of the Energy Charter Treaty ceases to have effect for the Union.
