Article 32 – Withdrawals
32.1 Any Contracting Party may at any time after two years from the date on which this Treaty has entered into force for it, notify the Depositary in writing of its withdrawal from this Treaty. The Depositary shall at once inform all Contracting Parties.
32.2 Withdrawal shall take effect one year from the date of receipt of the notification.
Article 54(a) of the Vienna Convention on the Law of Treaties states that a Party may withdraw from a treaty, provided it is done in conformity with the provisions of the treaty.
Thus, Article 32.1 provides that a Contracting Party may withdraw at any time after two years after the coming into force of the Treaty. Withdrawal is done by notifying the Depositary, in writing, of the decision to withdraw. The Depositary, in turn, must immediately inform all Contracting Parties.
According to Article 32.2, withdrawal takes effect one year after receipt of notification.
