The United States views the iranian government as an bastard, anti-democratic government whose nuclear aspirations and dreams of regional hegemony are destabilizing the Middle East. In its efforts to undermine the regimen and Iran ’ s nuclear program, the United States has sanctioned individuals, entities and organs of the iranian state ; freeze billions in assets ; conducted targeted military strikes ; and tacitly supported assassinations. Regarding Caracas, the United States is committed to punitively sanctioning the Maduro government after it invalidated the 2019 election of Juan Guaidó, with Venezuelan losses estimated at $ 30 billion and climbing. The U.S. Department of Justice has estimated that in the spring of 2019 alone, the Islamic Revolutionary Guard Corps ( IRGC ), a branch of the irani military, coordinated the “ clandestine transfer ” of approximately 10 million barrels of crude vegetable oil and millions more in condensation and gasoline, including to Maduro ’ mho beleaguered government in Caracas, netting Iran hundreds of millions of urgently needed dollars .
With Iran atop a fiscal cliff, the U.S. has redoubled its sanctions enforcement efforts to include seizures of iranian fuel and weapon exports that the U.S. contends either support international terrorism, are funding irani state terrorism, or both. While high-profile shipping seizures are not without case law, U.S. sanctions enforcement is straining traditionally accepted state demeanor in the maritime to such an extent that the United States is very likely operate at the limit of its sovereign assurance .
Issues of International Law
Iran ’ s use of warships to deliver fuel and arms to Venezuela, a move designed to deter U.S. intervention in the transfer, represents a major escalation in the United States ’ randomness conflicts with both states. therefore army for the liberation of rwanda, the United States ’ s aggressive sanctions enforcement against Iran has not violated international police of the sea, but this escalation could be black in the long term. Understanding where that line is requires a brief flat coat on the police of the sea. Factors that affect the legality of interdictions include the ship ’ randomness claimed identity, the location of the capture, the domestic and external authorities under which the interdict occurs and, specially important given facts at hand, whether the vessel is a warship .
Ships transiting the eminent seas are subject entirely to the jurisdiction of the express under whose flag they are sailing, a paradigm disembowel from both customary international law and modern treaty police. Customary international law is an amalgamation of norms, practices and judgments that enjoy wide external credence. As for treaties, the two cardinal multilateral pacts regulating country hindrance with foreign embark are the 1958 convention on the Law of the High Seas ( 1958 Convention ), which the United States has ratified and the 1982 United Nations Conventions on the Law of the Sea ( UNCLOS ). The United States has not ratified UNCLOS, but it has accepted large portions as accurately reflecting customary international law of the ocean .
Both treaty and customary external law forbid state interference with foreign-flagged vessels outside especial circumstances ( primarily the slave trade wind, illegal broadcasting and plagiarism ). In all other cases, Article 3 of the 1958 convention and Article 94 of UNCLOS forbid high-seas interdictions of extraneous vessels without pre-authorization from that vessel ’ s country. Additional rules prescribe rigid limits on the search and capture of board vessels. Taken holistically, the calculus suggests breaching accustomed jurisprudence or either treaty will produce entirely negative long-run outcomes for the violating express by degrading international legal norms that provide huge economic benefits to abiding states, frittering away diplomatic capital, and creating rhetorical or pretextual cover for the misdeeds of less scrupulous submit actors .
Factors affecting foreign-flagged ship and cargo seizures include the domestic and/or international legal justification for the seizure, the identities of the ship or cargo and of the state of matter conducting the capture, the nature of the cargo, and the placement of the capture. Treaty and customary law restrict seizures of alien merchant ships to ships transiting a state ’ s territorial waters, with an basically blanket ban against seizures on the high seas. critically, both the 1958 Convention and UNCLOS afford warships sovereign unsusceptibility on the high seas. Barring a warship unlawfully using force or differently transgress external jurisprudence, warships efficaciously have complete exemption of movement and action .
globally, UNCLOS has subsumed the 1958 Convention as the international law of the sea, though it is unratified by the United States. In law of the sea disputes, the Supreme Court and multiple circuits hold that U.S. law incorporates UNCLOS only to the extent that it reflects accustomed international police. This leaves the 1958 Convention as controlling in U.S. courts. however, despite the U.S ’ second ratification of the 1958 Convention, courts considering it must silent confront whether the relevant treaty provisions are “ self-executing. ” This differentiation, which has perennially fuzzy edges, is implemental to determining whether courts have jurisdiction to hear treaty law claims. Self-executing treaty provisions are those that can operate without implementing legislation. U.S. courts generally regard such provisions as equivalent to federal statutes when the treaty clearly empower administrator action in “ pursuance of its provisions ” and where existing legislation is adequate to enforce the treaty provision. Provisions that are not self-executing may create international commitments but are not binding federal law absent associated enforce legislation. The huge majority of treaty provisions are non-self-executing .
U.S. courts maintain that their jurisdictional bounds are entirely built-in or statutory and that accustomed international law is insufficient to restrict their authority on the high seas absent Congress explicitly abdicating legal power. The U.S. Court of Appeals for the Fifth Circuit tackled self-execution of 1958 Convention Article 6—curtailing jurisdiction over foreign vessels in external waters—in United States v. Postal, which involved a drug-runner seized in the southerly Caribbean. The postal court found Article 6 not to be self-executing and consequently that it could not restrict the legal power of U.S. courts. More broadly, international law defenses to U.S. jurisdiction broadly fail unless the motor hotel holds the treaty provision to be rightfully self-executing or the claimant can prove the court is statutorily precluded from exercising legal power in their specific scenario. While courts tend to uphold the principle of restricting the extraterritorial application of U.S. law, they are will to distinguish applications of the protective principle, granting U.S. courts high sea jurisdiction over offenses committed in violation of United States criminal law. That Postal and its offspring give the U.S. politics noteworthy latitude to justify extraterritorial jurisdiction on the high seas creates enormous friction with both the 1958 Convention and UNCLOS .
agency to Seize Ships Violating U.S. Law on the High Seas
ampere long as the United States does not ( 1 ) unilaterally appropriate ships or cargoes in another state ’ s territorial waters or ( 2 ) seize extraneous vessels on the high gear seas, it has a clear domestic statutory footing for the seizures that appears reproducible with domestic precedent and international legal principles as construed in U.S. courts. however, the U.S. must tread carefully in the absence of twin multilateral sanctions against the irani regimen .
U.S. sanctions alone provide a assortment of authorities through which the U.S. may seize iranian property. Those upon which the United States relies to seize iranian ship include, but are not limited to : the iranian Transactions and Sanctions Regulations ( ITSR ) ; statutory authority to seize assets of indicate alien terrorist organizations including the Iran Revolutionary Guard Corps ; and the Iran and Libya Sanctions Act of 1996, as incorporated into the International Emergency Economic Powers Act. In 2010 Congress amended the 1996 sanctions act to specifically ratchet sanctions on Iran ’ s petroleum industry. As for Venezuela, U.S. sanctions against the Maduro government largely target Venezuela ’ s fiscal sector, state-owned anoint company Petroleos de Venezuela, S.A. and entities related to terrorism and drug traffic .
Beyond sanctions, Congress has empowered U.S. law enforcement and courts to effect capture and forfeit of IRGC-associated assets pursuant to statutes regarding civil forfeit, including of nautical ship vessels and cargoes and regarding federal crimes of terrorism. The latter, 18 U.S.C. § 2332b, specifically grants extraterritorial and special maritime jurisdiction and is the section most frequently cited absolve seizures of Iran-related ship .
Presuming the U.S. has legal power, 14 U.S.C.A § 522 authorizes “ inspections, searches, seizures, and arrests upon the high seas ” for violations of U.S. law. Under 28 U.S.C. § 1333, the U.S. politics must assert a call in rem under admiralty jurisdiction to seize a transport or cargo. Obtaining a justify to do therefore requires satisfying two conditions : relevant placement and a link with nautical activity. The placement screen asks entirely whether the tort or injury occurred on navigable water or a vessel thereupon. The nexus test requires that the court buttocks both ( 1 ) whether the incident was disruptive of marine commerce and ( 2 ) whether the incident bears a “ substantial relationship to traditional nautical activity. ” In cases involving a marine tanker allegedly smuggling contraband fuel while transiting the open ocean, fulfilling the nexus and location tests is aboveboard sol hanker as the U.S. has early statutory bases for the capture .
There is a question as to whether the U.S. government could secure jurisdiction to seize vessels on the high seas through the Foreign Sovereign Immunity Act ( FSIA ). There are exceptions to FSIA unsusceptibility that could be implicated, including those regarding the United States Victims of State Sponsored Terrorism Fund ( USVSSTF ). The USVSSTF is funded partially through sales of seize iranian property pursuant to either the trading with the Enemy Act or “ any relate civil or criminal conspiracy, scheme, or other union crime related to doing business or acting on behalf of a express patron of terrorism. ” Sovereign unsusceptibility under the FSIA does not extend to politics vessels being used for commercial purposes, but it does apply to warships, as it has since the 1812 Schooner Exchange decision, which cemented U.S. adhesiveness to maritime sovereign exemption .
In the modern era, Congress authorizes seizures of vessels and cargoes on the high seas for violations of U.S police, and courts have repeatedly authorized the sale of extraterritorially seized iranian property to fund the USVSSTF. basically, the FSIA strips immunity where a suit is brought in admiralty to enforce nautical liens against a foreign express ’ randomness vessel or cargo, and the U.S. government is bringing suits to enforce maritime liens to fund awards in U.S. court judgments to victims of Iran-backed terrorism .
Though high ocean seizures distinctly conflict with external law, an aggressive U.S. administration might find this legal avenue tempt. however, domestic authorities entirely work domestically ; the United States would need to couch its actions so that the international community can not reasonably view them as motiveless, illegal attacks on extraneous merchant transport. This is a grandiloquent order. Interdicting extraneous transport without a solid legal international basis would seem to be precisely the kind of coercive behavior that U.N. Charter Article 2 ( 4 ) bars because of its corrosive electric potential .
slowly Spiraling escalation
Two holocene seizure cases—those of the Grace 1 and the Bella—demonstrate that the United States understands where the channel between treaty-compliant sanctions enforcement and illegitimate seizures of extraneous transport is. Briefly, when the United States wants to seize a foreign vessel without flag department of state accept, its options under international law are limited. They include co-opting sag state natural process against a vessel, use of third-party submit enforcement as the transport in motion transits their territorial waters ( as in Grace 1 ), the volunteer surrender of the ship or cargo to avoid fiscal or legal penalties in U.S. court for aiding the IRGC ( as in Bella ) or incentives through State Department counter-organized crime incentive programs.

That said, reciprocal seizures by Iran are significantly ratcheting tensions among nautical shippers transiting the persian Gulf. Given iranian willingness to react to U.S. efforts to unravel sanctions-evasion through norm-smashing escalation, a high-seas seizure could provoke an even more dramatic reception .
The Grace 1 and Stena Imperio provide one admonitory fib. On July 4, 2019, the british Royal Navy, operating aboard Gibraltar authorities and at the behest of the United States, seized the Panamanian-flagged supertanker M/T Grace 1 as it transited Gibraltar territorial waters. Grace 1 was carrying iranian blunt oil bounce for Syria in rape of U.S. sanctions. Panama had revoked Grace 1 ’ sulfur registration equitable weeks pre-seizure, leaving the ship homeless and vulnerable, but Iran quickly claimed the ship in an attempt to shield it from forfeit to the United States .
Gibraltar authorities initially invoked EU sanctions against the syrian regimen to keep Grace 1 impounded. however, as the courts churned, Iran retaliated by seizing the british tanker Stena Imperio in the Strait of Hormuz, ratcheting up pressure to release Grace 1. It worked. Gibraltar released the supertanker on an iranian promise that it was no longer Syria-bound. Iran then released the Stena Imperio. In the midst of this, Grace 1 vanished, though the United Kingdom reported that the oil ultimately arrived in Syria following a ship-to-ship transfer. The Grace 1 debacle illustrated that sanctions-evading shippers straying into U.S.-allied territorial waters is a black mistake but besides that EU states continue to prefer renewing an Iran deal over the United States ’ s proclivity for extraterritorial sanctions enforcement .
In July 2020, after failing to seize the Grace 1, the United States took bolder action to enforce its sanctions. pursuant to a U.S. federal court decree, the United States seized the fuel cargoes aboard four tankers bound from Iran to Venezuela as they exited the Persian Gulf—the purportedly Greek-owned, Liberian-flagged Bella, Bering, Pandi and Luna ( which I ’ ll denote to plainly as Bella. ) soon thereafter, the Justice Department announced that the U.S. had seized more than 1.1 million barrels of Iranian-origin fuel from the four ships suspected of belonging to the IRGC. The ships ’ respective owners, whose assets were seized by the Justice Department, asserted no such irani nexus existed and that they were bound not for Caracas but Trinidad. There is ample reason for intuition : among the most glower is that the flotilla disabled their trailing transponders after reaching Iran —a classic maneuver to avoid path scrutiny .
The Bella capture reflects distinctive U.S. practice of upholding extraterritorial jurisdiction in forfeit actions against foreign terrorist organizations and their boosters. But it is unique in that vitamin a bluff as the capture was, the United States did not directly use push. rather, the Bella flotilla surrendered its cargoes voluntarily to “ foreign partners ” of the United States, quite than to american english warships, allowing the United States to effectuate the capture without running afoul of the letter of external police. This was probably accomplished through the terror of sanctions enforcement against the ships ’ owners, insurers, and captains if they failed to comply .
The Iranians have shown no such restraint. immediately following the Bella capture, Iran dramatically interdicted the liberian oil tanker M/T Wila ( the Bella was besides liberian flagged ) to either reclaim the fuel or retaliate as it did with the Stena Imperio in 2019. More recently, in January 2021, Iran retaliated again by seizing the south korean M/T Hankuk Chemi, spuriously asserting that it seized the vessel for violating irani environmental rules. ultimately, the United States has therefore far remained within the bounds of accustomed external law while the crescendoing irani reply violates the 1958 Convention, UNCLOS and customary international law .
But the break between give U.S. legal action and obviously treaty-violative demeanor is narrower than it might appear .
Seizures Clearly Violating International Law
With Bella and Grace 1 as a baseline, only a few variables need to change for U.S. action to violate external law, potentially jeopardizing the legality of the arrests in U.S. courts in accession to damaging international norms .
Consider the postdate conjectural scenario : sometime in 2021, the United States obtains a sanction for the seizure of an irani oil tanker and its cargo on the grounds that this tanker is clandestinely transporting IRGC-owned fuel for sale in Venezuela in trespass of U.S. sanctions against both countries. The oil tanker is flying the irani pin and bears markings indicating it is an iranian warship. The United States identifies the oil tanker in international waters equitable before it passes into the South Atlantic. Fearing that it will deactivate its transponder and slip aside, the U.S. Navy interdicts and seizes. Mirroring Bella, the U.S. Navy tows the ship to a U.S. port with the intent to sell the fuel to benefit the USVSSTF .
This scenario alters three variables from late capture activity : ( 1 ) placement on the high seas ( distinguishing from Grace 1 ) ; ( 2 ) direct U.S. enforcement ( distinguishing from Bella ) ; ( 3 ) the oil tanker ’ second status as a warship ( distinguishing from all holocene priors ) .
careless of the domestic authority to do indeed, this scenario would violate both accustomed international jurisprudence and the relevant provisions of at least the 1958 Convention and UNCLOS, potentially along with U.N. Charter Article 2 ( 4 ). Boarding and seizing foreign-flagged vessels on the high seas without flag state of matter accept is prohibited demonstrably under external police except vitamin a related to specific jus cogens violations such as piracy or the slave trade .
If the tanker were a state-owned military vessel rather of a privately operated merchant ship, a U.S. capture would be an flush more crying treaty misdemeanor. however, as Iran is mindful, a U.S. capture of a foreign warship on the high sea is extremely improbable. This is because the United States has for decades led opposition to the demilitarization of international waters, establishing a status that exemption of seafaring and operation was necessity to U.S. naval exponent projection and because such actions fall within the UNCLOS article 88 necessity that states entirely use the senior high school seas for “ passive purposes. ” Absent open conflict with Iran, it would beggar impression for the United States to move that aggressively .
Warship caveat aside, the United States might creatively assert that because Iran did not ratify the 1958 Convention, it could not avail itself of Article 6 protections against intervention with iranian shipping. There is case law for this : In United States v. Gonzalez, the U.S. Court of Appeals for the Eleventh Circuit denied a Honduran-flagged ship Article 6 protections because Honduras had not ratified the treaty. Further, some might argue that Article II, § 2 of the U.S. Constitution ( granting the president sweeping powers as air force officer in foreman and in the kingdom of treatymaking ), provides ample authority for high sea interdictions of suspect iranian fuel and weapons shipments if the president of the united states believes doing so would protect U.S. national security interests. In short, without treaty ratification by both the United States and Iran, U.S. courts would probable dispatch any international police jurisdictional claim opposing a U.S. government capture .
To date, the United States has been cautious not to directly contravene either customary external law or the 1958 Convention in its nautical sanctions enforcement. however, the use of proxies to induce the “ voluntary ” forfeit of ships and cargoes, as in the Bella case, lies just inside the law ’ south bounds. Pushing far could produce awful prescriptive consequences.

freedom of maritime commerce and the United States ’ mho unmatched naval force have produced a geopolitical asymmetry that is supremely beneficial to american english political, economic and security interests. The international commitment to corporate security on the global ’ south oceans has proven fabulously fruitful for external peace and prosperity as merchant ships can trust in basically unchained access to global ship routes. That corporate security is endangered when states on a near-war foot lease in tit-for-tat transport seizures, particularly when one side, Iran, is paying lip service to international law at best .
The United States no long alone maintains the gravitas or naval brawn to enforce domestic judgments on the high seas, with China, in especial, growing increasingly assertive. Eroding flag-state reign on the high seas would be of huge value to less scrupulous state actors or those seeking to radically reshape the global club. If the United States were to push the boundaries any farther, it will struggle to legally oppose, for example, Beijing seizing vessels belonging to Indonesia or Taiwan for violating chinese jurisprudence in the South China Sea, or russian naval action in the Sea of Azov. The dangerous second-order effects of abridging traditional freedoms on the high gear seas must outweigh short-run foreign policy benefits .
