Andorra

13-02-2007

The Principality of Andorra does not consider itself bound by the provisions of article 31 which provide for a mandatory referral to the International Court of Justice of any dispute which cannot be resolved according to the terms of paragraph 1. The Government of Andorra takes the position that for any dispute to be referred to the International Court of Justice for decision the agreement of all the parties to the dispute shall be necessary in each individual case.

Argentina

20-02-2003

The Argentine Republic reiterates what was stated in its note of 4 February 1994, by which it rejected the declaration of territorial application of the above-mentioned Convention made on 3 June 1993 by the United Kingdom in respect of the Malvinas Islands, South Georgia and the South Sandwich Islands, which are an integral part of the national territory of Argentina. It also rejects the declaration of the United Kingdom purporting to extend the application of the 1971 Convention on Psychotropic Substances to the sector which it refers to as "British Antarctic Territory" and affirms that this declaration in no way affects the rights of sovereignty of the Argentine Republic over the Argentine Antarctic Sector.

Furthermore, the Argentine Republic rejects the declaration made by the United Kingdom in its note of 3 December 2002 and any other document, act or activity and their effects, which might arise from that declaration and from the purported territorial application, as well as the designation of these territories as dependencies of the United Kingdom.

The United Nations General Assembly adopted resolutions 2065 (XX), 3160 (XXVIII), 31/49, 37/9, 38/12, 39/6, 40/21, 41/40, 42/19 and 43/25, in which it recognizes the existence of the sovereignty dispute relating to the question of the Malvinas Islands and urges the Governments of the Argentine Republic and the United Kingdom to resume negotiations in order to find as soon as possible a peaceful and definitive settlement of the dispute, using the good offices of the Secretary-General of the United Nations, who was requested to report to the General Assembly on the progress made.

The Argentine Republic reaffirms its sovereign rights over the Malvinas Islands, South Georgia and the South Sandwich Islands as well as the surrounding maritime areas, which are part of its national territory. It also reaffirms its rights of sovereignty over the Argentine Antarctic Sector and the validity of the Antarctic Treaty, signed in Washington on 1 December 1959.

Israel

29-03-2018

The Permanent Mission of Israel to the United Nations presents its compliments to the Secretary-General of the United Nations, in his capacity as depositary of the Convention on Psychotropic Substances, dated 21 February 1971, and has the honor to refer to the Palestinian request to accede to this Convention (Reference number C.N.797.2017.TREATIES-VI.16).
‘Palestine’ does not satisfy the criteria for statehood under international law and lacks the legal capacity to join the aforesaid Convention both under general international law and the terms of bilateral Israeli-Palestinian agreements.
The Government of Israel does not recognize ‘Palestine’ as a State, and wishes to place on record, for the sake of clarity, its position that it does not consider ‘Palestine’ a party to the Convention and regards the Palestinian request for accession as being without legal validity and without effect upon Israel’s treaty relations under the Convention.

Palestine

18-03-2019

The Permanent Observer of the State of Palestine to the United Nations presents his compliments to the Secretary-General of the United Nations, in his capacity as Depositary, and has the honor to refer to depositary notification C.N.179.2018.TREATIES-VI.16, dated 4 April 2018, conveying a communication of Israel regarding the accession of the State of Palestine to the Convention on Psychotropic Substances, 21 February 1971.
The Government of the State of Palestine regrets the position of Israel and wishes to recall the United Nations General Assembly resolution 67/19 of 29 November 2012 according to which Palestine was accorded a ‘Non-member Observer State status in the United Nations’. In this regard, Palestine is a State recognized by the United Nations General Assembly on behalf of the international community.
As a State Party to the Convention on Psychotropic Substances, 21 February 1971, which entered into force on 29 March 2018 for the State of Palestine, the State of Palestine will exercise its rights and honor its obligations with respect to all States Parties. The State of Palestine trusts that its rights and obligations will be equally respected by its fellow States Parties.

The United States Mission to the United Nations presents its compliments to the Executive Office of the Secretary-General of the United Nations and refers to the U.N. Secretary-General’s depositary notification C.N.797.2017.TREATIES-VI.16, dated January 2, 2018, regarding the purported accession of the ‘State of Palestine’ to the Convention on Psychotropic Substances, done at Vienna February 21, 1971 (the Convention), for which the Secretary-General of the United Nations is the depositary.
The Government of the United States of America does not believe the ‘State of Palestine’ qualifies as a sovereign State and does not recognize it as such. Accession to the Convention is limited to sovereign States. Therefore, the Government of the United States of America believes that the ‘State of Palestine’ is not qualified to accede to the Convention and affirms that it will not consider itself to be in a treaty relationship with the ‘State of Palestine’ under the Convention.
