米華相互防衛条約
Senator Barry Goldwater and other members of the United States Congress challenged the right of President Jimmy Carter to unilaterally nullify the Sino-American Mutual Defense Treaty, which the United States had signed with the ROC in December 1954 and was ratified by the U.S. Senate in February 1955. Goldwater and his co-filers of the Supreme Court case "Goldwater v. Carter" argued that the President required Senate approval to take such an action of termination, under of the U.S. Constitution, and that, by not doing so, President Carter had acted beyond the powers of his office. The case ultimately was dismissed as non-justiciable, leaving open the constitutional question regarding a president's authority to dismiss a treaty unilaterally.
