46 U.S.C. § 60506 — Retaliation against British dominions of North America

(a) General Authority. The President may issue a proclamation barring vessels of the British dominions of North America — along with their masters, crews, and products made in or coming from those dominions — from entering United States waters, ports, or places. The President can do this only when satisfied that at least one of three situations has occurred: (1) U.S. fishermen or fishing vessels in the waters, ports, or places of the British dominions of North America have been, or recently have been: (A) denied rights that law or treaty gives them; (B) subjected to unreasonable restrictions on exercising those rights; or (C) otherwise harassed. (2) U.S. fishermen or fishing vessels that hold a U.S. permit to dock or trade at a port or place in the British dominions of North America have been, or recently have been: (A) denied the privilege of entering that port or place on the same terms given to trading vessels of the most-favored-nation; (B) blocked from buying supplies that are allowed to be sold to trading vessels of the most-favored-nation; or (C) otherwise harassed. (3) Other U.S. vessels, or their masters or crews, in the waters, ports, or places of the British dominions of North America have been, or recently have been: (A) denied privileges given to vessels of the most-favored-nation, or to their masters or crews; or (B) otherwise harassed. (b) Coverage and Exceptions. The President may apply the proclamation to any of the subjects named above, and may build in exceptions for vessels that are in distress or need supplies. The President may also change, revoke, or renew the proclamation at any time. (c) Penalties. Anyone who violates the proclamation can be fined under title 18, imprisoned for up to two years, or both. Any vessel or goods found in U.S. waters, ports, or places in violation of the proclamation may be seized and forfeited to the United States Government.
