Reservations made by Czechoslovakia upon signature and confirmed upon ratification:
"(1) The Czechoslovak Socialist Republic does not consider itself bound by article 16 providing for a compulsory procedure of arbitration for any dispute which may arise with respect to interpretation or application of the provisions of the Convention. The Czechoslovak Socialist Republic maintains that the consensus of all Parties to the dispute is indispensable in any particular case to be submitted for arbitration.
(2) The Czechoslovak Socialist Republic considers articles 17 and 19 to be of discriminatory character since, on the basis of their provisions, a number of States has been deprived of the possibility of becoming a Party to the Convention.
The Convention relates to matters which are of interest to all States; consequently, it has to be open for participation of all States. In accordance with the principle of sovereign equality, no States have the right to exclude other States from becoming a Party to the Convention of general interest.
(3) The latter reservation applies also to articles 22 and 23 for the same reasons."
Czechoslovakia had signed and ratified the Convention on 10 December 1965 and 8 August 1967, respectively, with reservations made upon signature and confirmed upon ratification.
