Artikel XIII

a) Any Party may withdraw voluntarily from EUTELSAT at any time by written notice to the Depositary as defined in Article XXI. Such withdrawal shall take effect three months after the date of receipt of the notice by the Depositary.
b) If a Party appears to have failed to comply with any obligation under the Convention, the Assembly of Parties, having received notice to that effect or acting on its own initiative, and having considered any representations made by the Party, may decide, if it finds that the failure to comply has occurred, that the Party be deemed to have withdrawn from EUTELSAT and, from the date of such decision, the Convention shall cease to be in force for that Party. An extraordinary meeting of the Assembly of Parties may be convened for this purpose.
c) A Party which has withdrawn or is deemed to have withdrawn from EUTELSAT shall cease to have any right of representation in the Assembly of Parties and shall incur no obligations or responsibility after the effective date of withdrawal except for liabilities arising from acts or omissions before that date.
d) Every notification of a withdrawal and every decision effecting a deemed withdrawal shall be communicated at once to all Parties by the Depositary.
