22 U.S.C. § 287c: Economic and communication sanctions pursuant to United Nations Security Council Resolution

Notwithstanding the provisions of any other law, whenever the United States is called upon by the Security Council to apply measures which said Council has decided, pursuant to article 41 of said Charter, are to be employed to give effect to its decisions under said Charter, the President may, to the extent necessary to apply such measures, through any agency which he may designate, and under such orders, rules, and regulations as may be prescribed by him, investigate, regulate, or prohibit, in whole or in part, economic relations or rail, sea, air, postal, telegraphic, radio, and other means of communication between any foreign country or any national thereof or any person therein and the United States or any person subject to the jurisdiction thereof, or involving any property subject to the jurisdiction of the United States. Any Executive order which is issued under this subsection and which applies measures against Southern Rhodesia pursuant to any United Nations Security Council Resolution may be enforced, notwithstanding the provisions of any other law. The President may exempt from such Executive order any shipment of chromium in any form which is in transit to the United States on March 18, 1977 . Any person who willfully violates or evades or attempts to violate or evade any order, rule, or regulation issued by the President pursuant to subsection (a) of this section shall, upon conviction, be fined not more than $1,000,000 or, if a natural person, be imprisoned for not more than 20 years, or both. a certificate of origin with respect to such shipment has not been filed with the Secretary; or in the case of a shipment with respect to which a certificate of origin has been filed with the Secretary, the Secretary determines that the information contained in such certificate does not adequately establish that the steel mill product in such shipment does not contain chromium in any form which is of Southern Rhodesian origin; The Secretary shall prescribe regulations for carrying out this subsection. In carrying out this subsection, the Secretary may issue subpenas requiring the attendance and testimony of witnesses and the production of evidence. Any such subpena may, upon application by the Secretary, be enforced in a civil action in an appropriate United States district court. The Secretary may exempt from the certification requirements of this subsection any shipment of a steel mill product containing chromium in any form which is in transit to the United States on March 18, 1977 . Under such circumstances as he deems appropriate, the Secretary may release from customs custody for entry into the United States, under such bond as he may require, any shipment of a steel mill product containing chromium in any form. the term “certificate of origin” means such certificate as the Secretary may require, with respect to a shipment of any steel mill product containing chromium in any form, issued by the government (or by a designee of such government if the Secretary is satisfied that such designee is the highest available certifying authority) of the country in which such steel mill product was produced certifying that the steel mill product in such shipment contains no chromium in any form which is of Southern Rhodesian origin; and the term “Secretary” means the Secretary of the Treasury. Upon the enactment of this Act [ Mar. 18, 1977 ], the President may suspend the operation of the amendments contained in this Act [amending this section] if he determines that such suspension would encourage meaningful negotiations and further the peaceful transfer of governing power from minority rule to majority rule in Southern Rhodesia. Such suspension shall remain in effect for such duration as deemed necessary by the President. If the President suspends the operation of the amendments contained in this Act [amending this section], he shall so report to the Congress. In addition, the President shall report to the Congress when he terminates such suspension. If the President suspends the operation of the amendments contained in this Act [amending this section], any reference in those amendments to date of enactment [ Mar. 18, 1977 ] shall be deemed to be a reference to the date on which such suspension is terminated by the President.”
