1. The Union shall be open to all European States which respect the values referred to in Article I-2, and are committed to promoting them together.

2. Any European State which wishes to become a member of the Union shall address its application to the Council. The European Parliament and national Parliaments shall be notified of this application.

The conditions and arrangements for admission shall be the subject of an agreement between the Member States and the candidate State. That agreement shall be subject to ratification by each contracting State, in accordance with its respective constitutional requirements.

1. On the reasoned initiative of one third of the Member States or the reasoned initiative of the European Parliament or on a proposal from the Commission, the Council may adopt a European decision determining that there is a clear risk of a serious breach by a Member State of the values referred to in Article I-2. The Council shall act by a majority of four fifths of its members after obtaining the consent of the European Parliament.

Before making such a determination, the Council shall hear the Member State in question and, acting in accordance with the same procedure, may address recommendations to that State.

The Council shall regularly verify that the grounds on which such a determination was made continue to apply.

The European Council shall act unanimously after obtaining the consent of the European Parliament.

3. Where a determination under paragraph 2 has been made, the Council, acting by a qualified majority, may adopt a European decision suspending certain of the rights deriving from the application of the Constitution to the Member State in question, including the voting rights of the member of the Council representing that State. The Council shall take into account the possible consequences of such a suspension for the rights and obligations of natural and legal persons.

In any case, that State shall continue to be bound by its obligations under the Constitution.

Abstentions by members present in person or represented shall not prevent the adoption of European decisions referred to in paragraph 2.

For the adoption of the European decisions referred to in paragraphs 3 and 4, a qualified majority shall be defined as at least 72% of the members of the Council, representing the participating Member States, comprising at least 65% of the population of these States.

Where, following a decision to suspend voting rights adopted pursuant to paragraph 3, the Council acts by a qualified majority on the basis of a provision of the Constitution, that qualified majority shall be defined as in the second subparagraph, or, where the Council acts on a proposal from the Commission or from the Union Minister for Foreign Affairs, as at least 55% of the members of the Council representing the participating Member States, comprising at least 65% of the population of these States. In the latter case, a blocking minority must include at least the minimum number of Council members representing more than 35% of the population of the participating Member States, plus one member, failing which the qualified majority shall be deemed attained.

That agreement shall be negotiated in accordance with Article III-325(3). It shall be concluded by the Council, acting by a qualified majority, after obtaining the consent of the European Parliament.

3. The Constitution shall cease to apply to the State in question from the date of entry into force of the withdrawal agreement or, failing that, two years after the notification referred to in paragraph 2, unless the European Council, in agreement with the Member State concerned, unanimously decides to extend this period.
