The Treaty of Accession consists of several parts. The overarching document is the short Treaty concerning the accession of the Republic of Bulgaria and Romania to the European Union. Attached to the Treaty is the Act of Accession and its Annexes. This act enters into force only in the event that the Constitution is not in force on the date of accession. Its contents are the same, in substance, as those of the Accession Protocol. Once the Constitution enters into force the Accession Protocol will replace the Act of Accession.
Note: the Accession Protocol and its Annexes form an integral part of the Treaty of Accession
