The Case–Zablocki Act of 1972 is an American law, still in effect, designed to ensure that Congress would be informed about the international commitments made by executive agreements.
The law was named after Democratic Congressman Clement Zablocki of Wisconsin and Republican Senator Clifford P. Case of New Jersey.
In 1978, new Congressional resolutions strengthened the law, spelling out the reporting requirements in more detail, and including as well oral agreements.
[1] The White House argued that the law was inconsistent with the president's constitutional right to direct foreign policy.
Disputes between Congress and the President have arisen when the former has become aware of certain controversial agreements, such as intelligence commitments and access to important bases, after the deadline.
