Why Do Nations Voluntarily Limit Their Jurisdictional Reach Over Stateless Vessels?

Stateless Vessels.”

Despite the fact that the oceans are extensively used for contraband smuggling, including narcotics, there is not a correspondingly robust legal regime at sea for contending with this problem. Except for a very limited coastal State entitlement to ‘prevent’ customs offenses (including narcotic trafficking) in the contiguous zone, the flag State alone is entitled to exercise prescriptive, enforcement and adjudicative jurisdiction over its vessels and those aboard them for such offenses in all waters outside the sovereign waters (i.e. territorial sea and inward) of another State. UNCLOS Article 108 merely exhorts States to cooperate in combatting narcotics trafficking at sea, and treaties such as the United Nations Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances (hereinafter Vienna Drug Convention), the Jeddah Amendment to the Djibouti Code of Conduct, and Caribbean bilateral agreements typically just provide fidelity on how such cooperation should occur. The Right of Visit (ROV) per UNCLOS Article 110 is a useful tool, but is limited to a determination of vessel nationality only – jurisdiction over a vessel for any narcotics trafficking offenses remains the sole province of the flag State in the case of a properly flagged vessel.

Specific to the issue of law enforcement jurisdiction at sea, Article 4 of the Vienna Drug Convention requires Parties to take measures to establish jurisdiction over violations of their narcotics criminal laws occurring in their territory or on board a vessel flying their flag. It also suggests that Parties take measures (such as obtaining flag State consent) to establish jurisdiction over vessels flying the flag of another State. What Article 4 does not touch on is the ability of States to establish and exercise jurisdiction over vessels without nationality or those assimilated to vessels without nationality under international law (collectively referred to hereinafter for ease of reference as stateless vessels).

Recognizing that the inability to exert maritime law enforcement jurisdiction over stateless vessels creates a significant gap in the overall global effort to combat narcotics trafficking at sea, some nations have extended their jurisdictional reach more robustly over such vessels. For example, Article 3 (Jurisdiction) of the 1995 Council of Europe’s ‘Agreement on Illicit Traffic by Sea,’ implementing Article 17 of the Vienna Drug Convention, requires a State Party to ‘take such measures as may be necessary to establish its jurisdiction over the relevant offences committed on board a vessel which is without nationality, or which is assimilated to a vessel without nationality under international law.’ Similarly, the U.S. fulfilled its obligations under Article 4 of the Vienna Drug Convention by expanding (and routinely exercising) its jurisdictional reach over stateless vessels in its principal maritime narcotics smuggling law, the Maritime Drug Law Enforcement Act (MDLEA).1

Unfortunately, such robust jurisdictional postures with respect to stateless vessels engaged in narcotics trafficking at sea are more the exception than the norm. It is not entirely clear whether the failure by many States to more aggressively assert jurisdiction over stateless vessels is the product of legislative lethargy (it requires affirmative action by a State to decide on, adopt, and publicize an enhanced jurisdictional posture) or a mistaken belief that a more robust posture is forbidden by or contrary to international law. As demonstrated below, this second basis is legally incorrect, and to the extent nations are failing to adopt a more robust jurisdictional posture toward stateless vessels based on it, they are voluntarily and needlessly restraining themselves to the ultimate benefit of maritime criminals.

Neither Conventional law, customary international law, nor decisions of international tribunals prevent a more robust exercise of jurisdiction over stateless vessels. The Conventional (or treaty) law of nations, as embodied in UNCLOS, does not answer the question of the extent of jurisdiction States may exercise over Stateless vessels. All it says, in Article 92(2), is that ‘[a] ship which sails under the flags of two or more States, using them according to convenience, may not claim any of the nationalities in question with respect to any other State, and may be assimilated to a ship without nationality.’ This provision is unsatisfactory in several ways. First, it only relates to one of several means by which a vessel can be considered stateless for jurisdictional purposes – it is entirely silent as to other means (e.g. true statelessness, failure to make a claim of nationality). Also, it provides no guidance at all on the ultimate issue, which is the jurisdictional consequence of a vessel being ‘assimilated to a ship without nationality.’

Equally unsatisfying in terms of establishing or defining the international law related to jurisdiction over stateless vessels is State practice. Customary international law results from a general and consistent practice of States that they follow from a sense of legal obligation. A doctrine or principle that rises to the level of customary international law is binding on States to the same extent as treaty law. Unfortunately, as comprehensively addressed in Chapter 15 of the United Nations Office on Drugs and Crime’s Maritime Crime: A Manual for Criminal Justice Practitioners (3rd ed.), ‘there is no settled answer’ in State practice to the scope of jurisdiction that a boarding State may assert over a stateless vessel. According to the Manual, ‘[s]ome States may determine that they can, in effect, treat the vessel as one of the boarding State’s own nationality’ and as a consequence ‘may claim that it can assert the same jurisdiction over the suspect vessel as it could assert over a vessel of its own nationality.’ However, ‘[o]ther States may be of the view that the statelessness as such of the vessel does not suffice in order to assert jurisdiction over the vessel and the persons on board. Accordingly, they would assert jurisdiction only if there is some other jurisdictional link with the activity of the vessel or the persons concerned’ – such as, for example, an assault on a boarding officer during a ROV boarding. Which viewpoint is correct is not the point here. Rather, the mere fact that this divergence in practice exists, by definition, means there is no settled customary international law that settles the issue.

The consequence of international conventional law that remains largely silent on the issue of the jurisdictional effect of vessel statelessness, and State practice falling into one of two divergent camps, is there is no definitive ‘rule of international law’ on the issue of stateless vessel jurisdiction. In such a case, the Lotus principle (deriving from Case of the S.S. “Lotus” (Fr. v. Turk.), 1927 P.C.I.J. (Ser. A) No. 10), which is a fundamental principle of international law, stands for the proposition that ‘[the absence of a definitive rule] leaves [States] a wide measure of discretion, which is only limited in certain cases by prohibitive rules. As regards other cases, every State remains free to adopt the principles which it regards as best and most suitable.’

In other words, the focus in the absence of generally accepted law is not on whether international law permits a certain action, but rather whether is prohibits such an action. In the absence of such a prohibition, ‘all that can be required of a State is that it should not overstep the limits which international law places upon its jurisdiction; within these limits, its title to exercise jurisdiction rests in its sovereignty.’

In 2024, the U.S. Ninth Circuit Court of Appeals in United States v. Marin (No.22-50154, decided on January 17, 2024) applied the Lotus principle to uphold a provision of the MDLEA that permits the U.S. to assert prescriptive, enforcement, and adjudicative jurisdiction on the basis of statelessness over ‘a vessel aboard which the master or individual in charge makes a claim of registry and for which the claimed nation of registry does not affirmatively and unequivocally assert that the vessel is of its nationality.’ According to the court, ‘[d]efendants do not identify a rule of international law requiring an oral claim to nationality be rebuttable only by a denial by the claimed flag state. In fact, such a rule could lead to the untenable result that neither the boarding state nor the claimed flag state have jurisdiction over a vessel so long as the claimed flag state does not confirm or deny nationality —undermining international law’s role of facilitating the “achievement of common aims.”’ Since, according to the Marin court, no international law prohibits the specific practice at issue, the U.S.’s exercise of jurisdiction on this basis ‘is not contrary to international law under the Lotus principle’ and does not ‘overstep the limits which international law places upon . . . jurisdiction.2

A U.S. court ruling is most certainly not determinative on the issue outside the United States. However, that ruling squarely addressed the international legality of perhaps the most aggressive of the situations in the MDLEA that permits the U.S to exercise jurisdiction over a vessel on the basis of statelessness, and determined that there was no rule of international law forbidding such an exercise in that situation. Assuming this conclusion is correct, application of the Lotus principle leads to a conclusion that the U.S. or any other nation choosing to adopt this particular approach to stateless vessel jurisdiction is free to do so as an exercise of State sovereignty.

The same conclusion would apply to any other approach not specifically prohibited by international law. In fact, it can be argued that in view of the invitation, if not mandate, on States to expand their jurisdictional reach as a central component of the global scheme to cooperatively address the scourge of narcotics trafficking at sea, the failure by States to avail themselves of mechanisms not prohibited to them by international law is a self-inflicted infirmity that weakens the global commitment to good order at sea and unnecessarily cedes legal ‘space’ at sea to would-be traffickers and other purveyors of maritime disorder.

The bottom line is that States should clarify the extent and parameters of their jurisdiction over stateless vessels in their domestic laws. In doing so, they should join the States that, according to the UNODC, ‘determine that they can, in effect, treat the vessel as one of the boarding State’s own nationality’ and as a consequence ‘may claim that it can assert the same jurisdiction over the suspect vessel as it could assert over a vessel of its own nationality.’ There is no legal bar to them doing so, and failure to do so merely weakens their own maritime law enforcement power and the overall global scheme to address disorders at sea. And finally, though the focus of this analysis is on narcotics trafficking, that is merely for illustrative purposes. There is no reason whatsoever that nations could not similarly extend their jurisdictional reach over stateless vessels for any other types of maritime crimes or disorders, subject to any other legal limitations that might exist.3

2 There have been some international court rulings that call into question the continued vitality of the Lotus principle in the jurisdictional context. However, those cases related to jurisdiction over universal crimes (such as war crimes or piracy), which, being international crimes, cannot by definition be the subject of differential state jurisdictional interpretations. That is not so with respect to non-universal crimes like narcotics smuggling; the 1988 Vienna Convention, for example, acknowledges the competency of States to craft criminal prohibitions and their jurisdictional reach, even as it provides guidelines on the types of criminal activities such laws should address. It is the author’s view – not to mention that of the U.S. Ninth Circuit – that the Lotus principle, rooted as it is in State sovereignty, is alive and well in the context of jurisdiction over non-universal crimes, including narcotics enforcement.

“Legal Finish” in Maritime Security is Too Often Lacking a Legal Start

By Dr. Ian Ralby

“Legal Finish” is a term that has become commonplace in maritime security circles around the world. It refers to the process of putting a maritime law enforcement action through a legal mechanism – whether a prosecution, administrative proceeding or other adjudication – that formally assesses offenses under national law and where appropriate, penalizes perpetrators. Legal finish has rightly been identified as crucial because merely disrupting illicit activities does little to deter future criminal conduct; only enforcing legal consequences changes the risk-reward calculus for nefarious actors. The problem, however, is that with all the focus on the legal finish, many states, international organizations, and “capacity building” partners have forgotten the legal start. 

Maritime law enforcement is not a linear process, it is a cycle that starts and ends with the law. Recognizing its recursive nature is essential to establishing clear, consistent, and effective law enforcement and security operations.

Figure 1. The Maritime Security Cycle.

To begin with, the law is the framework by which the maritime domain is assessed. Armed with the legal framework, maritime watchstanders can monitor and surveil the maritime domain, looking for any anomalies. Once they find those anomalies, however, a rigorous analytical process is needed to ensure that information is turned into understanding –about both what is happening on the water and what can be done about it. That analytical process, therefore, relies heavily on understanding the law. The key questions are:

  1. Is the anomaly desirable or undesirable? (Not all anomalies are undesirable).
  2. If it is undesirable, is it legal or illegal? (Not all undesirable matters have been addressed by the law).
  3. If it is illegal, is it actionable or not? (Does the state have the authority and jurisdiction to do something about it?)
  4. If it is actionable, is it achievable or not? (Does the state have the right physical capacity and capability to interdict the matter?)
  5. Even if it is undesirable, illegal, actionable, and achievable, would interdicting the matter be wise? (Is it worth the fuel, is it worth the risk, could there be geopolitical blowback, etc.?)

If the answer to any of these questions is “no,” then there should still be consideration of one additional question: “Is there anything else that could be done?” Watching the situation further, notifying other agencies, issuing a notice to mariners, or contacting neighboring states are all on the long list of other things that might be worth doing, short of pursuing an interdiction.

If the analysis suggests that an on-the-water operation might be warranted, then the analysts must have access to some sort of mechanism for sharing information with the proper decision-makers. Whether it is operative within an agency or across agencies, that cooperative mechanism must be repeatable (so there is consistency in how things happen), documentable (so there is a chance to learn from both successes and mistakes), and structured in such a manner that adequate information gets to the appropriate decision makers efficiently. 

Once decision-makers have information about an anomaly that is undesirable, illegal, actionable, achievable, and worth pursuing, it is up to them to decide whether to conduct an operation. If they choose to do so, the operation must be planned and executed in a manner consistent with the law. That requires not only a clear understanding of the authorities that the respective agencies have for law enforcement, and the limitation of enforcement jurisdiction in the maritime domain, but also a sufficient grasp of all the elements of an offense to be able to identify and document those elements at sea. The collection and preservation of evidence in the maritime space is crucial, especially since revisiting a “crime scene” at sea is rarely, if ever possible. Thus, understanding the law at the operational stage – both in the sense of what the law enforcement officers do and concerning what they notice and record – is vital to legal finish. But that understanding is usually in the hands of completely different people than those responsible for the legal finish. 

Importantly, arrests of people do not happen at sea. While it is possible to arrest a vessel, the suspects themselves are detained at sea and brought back to shore. Only once on shore are they handed over to land-based authorities who, on reviewing whatever evidence has been collected, then conduct an arrest or initiate an administrative proceeding. An arrest would then trigger the start of a prosecution, adjudication, and, if successful, penalization of the case. An administrative proceeding would similarly assess some sort of penalty. In either case – both considered to be “legal finish” – the personnel responsible are almost always different than the ones involved in every prior step of the process. All too often, however, most of the support, training, capacity building, attention, and funding has gone to this final stage, while the role of the law and legal advisors has been ignored in all the others.

Legal advisors are rarely, if ever, part of the process of monitoring and surveilling the maritime domain, analyzing anomalies, sharing information, planning operations, or even executing operations. They are sometimes – but rarely – consulted regarding evidence collection and preservation. Usually, the first time lawyers are brought into the maritime security cycle is for the legal finish, and it is left to them to kick-save any legal mistake or oversight that has been made at any previous point in the cycle. There is only so much, however, that can be fixed at the end of the process. Additionally, there may have been operational options that would have been more impactful if legal consultations had occurred earlier. Maritime law is strange and it affords some rights and opportunities that are sometimes hard to believe. Operators may miss out on more effective operations due to a lack of legal input at that stage.

Because maritime law enforcement is a cycle rather than a linear process, it does not end if one of the steps breaks down or even if all of them are successful through to prosecution. The final step is to revisit the starting point – the law – to ensure that it is fit for purpose. Law has two main functions: to constrain bad action and to enable good. If the law does not address an undesirable activity occurring in the maritime domain, it should be expanded or amended. If that law is not creating space for “good,” economically productive, and desirable activities, it should also be amended. While maritime law enforcement focuses on “the bad,” governing the maritime domain requires recognizing a balance between the two. Only stamping out the bad is not possible; there must be ample opportunities for good, lawful activities as well – especially when they are vital to a state’s economic security. 

To be most effective, therefore, in both promoting good activities and stopping bad ones, the law must be seen as a tool or an asset for law enforcement – much the way a ship, radar system, or even a weapon would be seen. To be as impactful as possible, the law must be calibrated for the security operating environment. But even perfect law will be virtually worthless unless those who understand it and know how to use it are involved from the start of the maritime security cycle. Relegating the law to the legal finish phase betrays a lack of appreciation for the centrality of the law to the entire cycle, and sets up the state for failure.

Legal finish is incredibly important. But so is the legal start. If operational lawyers are not recognized as playing a vital role in all the phases leading up to the handover to land-based authorities, the prospects of both effective operations and successful legal finish are being undermined. So, for all the good attention that has been paid to prosecutors and judges, as well as to the work of coast guard and navy lawyers in support of those prosecutions or administrative proceedings, much more must be done to back up and start integrating sound legal advice throughout the maritime security cycle. While this can be a challenge, as operational cultures tend to not be welcoming to legal advisors, it is not about disrupting missions and operations with annoying legal points. It is about enhancing missions and operations by safeguarding the likelihood of their success. As simple as it sounds, we must not lose sight of the reality that legal finish needs a legal start.
