The Government of Bolivia maintains, in agreement with the context of the Bogotá Charter, that “the respect for and the faithful observance of treaties” which is upheld in Articles 5 and 14 as a standard of international relations, does not exclude the revision of those articles by the peaceful procedures which are referred to in Articles 21, 22, and 23 of that Charter, when they affect the fundamental rights of States.
United States:
(Reservation made at the time of ratification)
That the Senate give its advice and consent to ratification of the Charter with the reservation that none of its provisions shall be considered as enlarging the powers of the Federal Government of the United States or limiting the powers of the several states of the Federal Union with respect to any matters recognized under the Constitution as being within the reserved powers of the several states.
Guatemala
