Argentina

03-10-1983

The Government of Argentina makes a formal objection to the [declaration] of territorial extension issued by the United Kingdom with regard to the Malvinas Islands (and dependencies), which that country is illegally occupying and refers to as the "Falkland Islands.
The Argentine Republic rejects and considers null and void the [said declaration] of territorial extension.

Objection United Kingdom, 28-02-1985

The Government of the United Kingdom of Great Britain and Northern Ireland have no doubt as to their right, by notification to the Depositary under the relevant provisions of the above-mentioned Convention, to extend the application of the Convention in question to the Falkland Islands or to the Falkland Islands Dependencies, as the case may be.
For this reason alone, the Government of the United Kingdom are unable to regard the Argentine [communication] under reference as having any legal effect.

Israel

01-05-2018

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 Supplementary Convention on the Abolition of Slavery, the Slave Trade, and Institutions and Practices Similar to Slavery, dated 7 September 1956, and has the honor to refer to the Palestinian request to accede to this Convention (Reference number C.N.158.2018.TREATIES-XVIII.4).
‘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

The Government of the State of Palestine regrets the position of Israel and wishes to recall United Nations General Assembly resolution 67/19 of 29 November 2012 according Palestine ‘nonmember observer State status in the United Nations’.

As a State Party to the Supplementary Convention on the Abolition of Slavery, the Slave Trade, and Institutions and Practices Similar to Slavery, dated 7 September 1956, which entered into force 22 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.

United States of America

01-05-2018

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.158.2018.TREATIES-XVIIl.4, dated March 23, 2018, regarding the purported accession by the ‘State of Palestine’ to the Supplementary Convention on the Abolition of Slavery, the Slave Trade, and Institutions and Practices Similar to Slavery, done at Geneva September 7, 1956 (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.
