Any government bill authorizing the ratification of a treaty pertaining to the accession of a state to the European Union shall be submitted to referendum by the president of the republic.

Notwithstanding the foregoing, by passing a motion adopted in identical terms in each House by a three-fifths majority, Parliament may authorize the passing of the bill according to the procedure provided for in paragraph three of article 89.

[Article 88-5 is not applicable to accessions that result from an Intergovernmental Conference whose meeting was decided by the European Council before July 1, 2004.]
