The Case Zablocki Act of 1972 requires the president to inform the Senate of any executive agreement within 60 days. The powers of the President to enter into such agreements have not been granted. The notification requirement allowed Congress to vote in favor of cancelling an executive agreement or to refuse to fund its implementation.   In the United States, executive agreements are internationally binding when negotiated and concluded under the authority of the president in matters of foreign policy, commander-in-chief of the armed forces, or a previous act of Congress.

As executive agreements are concluded on the authority of the President-in-Office, they do not necessarily bind his successors. Note: An executive agreement does not have the same weight as a treaty unless it is supported by a joint resolution. . . .
