Artikel 40

1. This Convention may be denounced by a High Contracting Party only after the conclusion of a period of five years from the date of its entry into force for the Party in question. Such denunciation shall be subject to six months' notice, which shall be communicated to the Secretary-General of the Council of Europe, who shall inform the other Contracting Parties.
2. Denunciation shall not release the High Contracting Party concerned from its obligations under this Convention in respect of disputes relating to facts or situations prior to the date of the notice referred to in the preceding paragraph. Such dispute shall, however, be submitted to the appropriate procedure under the terms of this Convention within a period of one year from the said date.
3. Subject to the same conditions, any High Contracting Party which ceases to be a Member of the Council of Europe shall cease to be a party to this Convention within a period of one year from the said date.
