7 “Art. 27. Violation of Treaty Obligations, (a) If a State fails to carry out in good faith its obligations under a treaty, any other party to the treaty, acting within a reasonable time after the failure, may seek from a competent international tribunal or authority a declaration to the effect that the treaty has ceased to be binding upon it in the sense of calling for further performance with respect to such State. ‘ ‘ (b) Pending agreement by the parties upon and decision by a competent international tribunal or authority, the party which seeks such a declaration may provisionally suspend performance of its obligations under the treaty vis-à-vis the State charged with failure. “ (c) A provisional suspension of performance by the party seeking such a declaration will not be justified definitively until a decision to this effect has been rendered by the competent international tribunal or authority.” 29 A.J.I.L.
