Reservation:

"To the extent, [...], that any law relating to land in Tonga which prohibits or restricts the alienation of land by the indigenous inhabitants may not fulfil the obligations referred to in article 5 (d) (v), [...], the Kingdom of Tonga reserves the right not to apply the Convention to Tonga.
Declaration:

"Secondly, the Kingdom of Tonga wishes to state its understanding of certain articles in the Convention. It interprets article 4 as requiring a party to the Convention to adopt further legislative measures in the fields covered by sub-paragraphs (a), (b) and (c) of that article only in so far as it may consider with due regard to the principles embodied in the Universal Declaration of Human Rights and the rights expressly set forth in article 5 of the Convention (in particular the right to freedom of opinion and expression and the right to freedom of peaceful assembly and association) that some legislative addition to or variation of existing law and practice in those fields is necessary for the attainment of the end specified in the earlier part of article 4. Further, the Kingdom of Tonga interprets the requirement in article 6 concerning `reparation or satisfaction' as being fulfilled if one or other of these forms of redress is made available and interprets `satisfaction' as including any form of redress effective to bring the discriminatory conduct to an end. In addition it interprets article 20 and the other related provisions of Part III of the Convention as meaning that if a reservation is not accepted the State making the reservation does not become a Party to the Convention.
"Lastly, the Kingdom of Tonga maintains its position in regard to article 15. In its view this article is discriminatory in that it establishes a procedure for the receipt of petitions relating to dependent territories while making no comparable provision for States without such territories. Moreover, the article purports to establish arocedure applicable to the dependent territories of States whether or not those States have become parties to the Convention. His Majesty's Government have decided that the Kingdom of Tonga should accede to the Convention, these objections notwithstanding because of the importance they attach to the Convention as a whole."
