Czechoslovakia: (Translation) "Acceding to the Convention we declare that the provision of its Article XIII is contrary to the Declaration of the United Nations General Assembly on Granting Independence to Colonial Countries and Peoples and that the provision of its Article XV on the obligatory jurisdiction of the International Court is contradictory to the principle of the international law on free selection of means for the settlement of disputes between States."
In a letter dated 2 May 1991, the Government of Czechoslovakia has notified the withdrawal of the above-mentioned reservation concerning Article XV.
