152 WRIGHT— CONCLUSIVENESS OF THE ACTS 



29. Exchange of Ratifications under Authority of the President. 

 Even after the treaty has been ratified** by both parties and 



interpretations, reservations or amendments properly consented to, 

 the foreign nation can not hold the United States bound until 

 ratifications have been exchanged.*^ This act, performed under 

 authority of the President,*'' gives the treaty complete international 

 validity, which, so far as international obligations are concerned, 

 is then held to date back to the time of signature unless expressly 

 stated otherwise in the treaty itself.*^ 



It thus appears that foreign nations recognize their duty to 

 know the organization of the full treaty power under the Constitu- 

 tion. They recognize that the United States is not responsible for 

 any instrument beyond the instructions of the negotiators and is 

 not bound by a treaty, signed or ratified merely under authority of 

 the President without advice and consent of the Senate. They 

 have likewise recognized that reservations or amendments, not 

 consented to by the whole treaty power, do not bind the United 

 ■States unless there is reason to suppose that such action had taken 

 place. 



30. Treaty Provisions Ultra Vires from Lack of Original Authority. 

 Difficulties, however, arise in cases where the constitutional law 



defining the competence of the organ for making agreements is 



obscure. In such cases, is the foreign nation justified in accepting 



the President's interpretation of the Constitution? We must recall 



that the President is for them the only official source of information 



of the United States, Great Britain, and Persia, which apparently were 

 tacitly accepted. Malloy, p. 2129. See also supra, note 35. 



** Ratification in the United States is under authority of the President 

 alone and he may refuse to ratify treaties after the Senate has consented.
