Membership Amended

***Notes re: original agreement being amended: The instrument of ratification included the Channel Islands and the Isle of Man. In a Note of 20 June 1989, the Foreign and Commonwealth Office, on behalf of the Governments of the United Kingdom, France and the United States of America, communicated the following to the Government of the Union of Soviet Socialist Republics: 'In a communication to the Government of the Union of Soviet Socialist Republics, which is an integral part (Annex IVA) of the Quadripartite Agreement of 3 September 1971, the Governments of the United Kingdom, France and the United States, without prejudice to the maintenance of their rights and responsibilities relating to the representation abroad of the interests of the Western Sectors of Berlin, confirm that, provided that matters of security and status are not affected and provided that the extension is specified in each case, international agreements and arrangements entered into by the Federal Republic of Germany may be extended to the Western Sectors of Berlin in accordance with established procedures. For its part, the Government of the Union of Soviet Socialist Republics, in a communication to the Governments of the Three Powers which is similarly an integral part (Annex IVB) of the Quadripartite Agreement, affirmed that it would raise no objections to such extension. The established procedures referred to above, which were endorsed in the Quadripartite Agreement, are designed inter alia to afford the authorities of the Three Powers the opportunity to ensure that international agreements and arrangements entered into by the Federal Republic of Germany which are to be extended to the Western Sectors of Berlin are extended in such a way that matters of security and status are not affected. When authorising the extension of the above-mentioned Convention to the Western sectors of Berlin, the authorities of the Three Powers took such steps as were necessary to ensure that matters of security were not affected. Accordingly, the Berlin declaration made by the Federal Republic of Germany in accordance with established procedures is valid and the Convention for the Conservation of Antarctic Seals applies to the Western Sectors of Berlin, subject to Allied rights and responsibilities. Moreover, the Soviet communication contains an incomplete and consequently misleading reference to the Quadripartite Agreement. The relevant passage of that Agreement to which the Soviet communication refers, provides that the ties between the Western Sectors of Berlin and the Federal Republic of Germany will be maintained and developed, taking into account that these sectors continue not to be a constituent part of the Federal Republic of Germany and not to be governed by it. With regard to the Antarctic Treaty of 1 December 1959, the Three Powers have the honour to refer to the Department of States's Note of 21 August 1980, communicated by the Government of the United States of America, as Depository of the Treaty, to all Parties to the Treaty on 12 January 1981, which elaborates the position of the Three Powers that the extension of this Treaty to the Western Sectors of Berlin is entirely consistent with the Quadripartite Agreement'.
