46 U.S.C. § 70305 — Suspension of passenger services

(a) If the President finds that a foreign nation lets a terrorist or terrorist group use its territory for operations, training, or sanctuary, or arms, aids, or supports it, and that group knowingly uses illegal seizure or threatened seizure of passenger vessels as policy, the President may suspend passenger-service rights to or from that nation’s port for passenger-vessel^* common carriers, and the right of a United States passenger vessel^* to use that port. The suspension may be without notice or hearing and may last as long as the President finds necessary to protect vessels from unlawful seizure. (b) No covered carrier or United States passenger vessel may operate in violation of the suspension. (c)(1) The Secretary^* may deny United States port entry to vessels of a person who operates in violation. (2) The violator owes the United States a civil penalty of up to $50,000. Each day a vessel uses a prohibited port is a separate violation.
