Introduction
This essay will determine whether the Republic of Tavern can secure an order from the International Tribunal for the Law of the Sea (ITLOS) for the release of Dr. Martyr’s vessel and crew from detention by the Democratic Republic of Pub. The facts involve the capture of a Taverni fishing vessel on the high seas by a Pub warship during an armed conflict. Following the capture, opium was discovered on board, leading to criminal charges in Pub. The vessel and crew remain in custody even after the conflict has ended, resulting in severe personal consequences for the crew. This analysis will first establish the jurisdiction of ITLOS to hear such a request, specifically under the prompt release provisions of the United Nations Convention on the Law of the Sea (UNCLOS). It will then examine the legality of the initial capture during the armed conflict and the subsequent continued detention on criminal grounds. The central argument is that while the initial capture was likely lawful under the laws of armed conflict, the continued detention may contravene Pub’s obligations under UNCLOS, making an order for prompt release from ITLOS attainable, though subject to the posting of a reasonable bond.
The Jurisdiction of ITLOS for Prompt Release
The Republic of Tavern seeks an order from ITLOS for the release of its vessel and crew. The primary mechanism for such an action is found in Article 292 of UNCLOS, which establishes a special procedure for the "prompt release of vessels and crews". For Tavern to successfully bring an application under this article, certain conditions must be met. First, a vessel flying its flag must have been detained. Here, the fishing vessel was from Tavern, and its crew were all citizens of Tavern, satisfying the nationality requirement. Second, it must be alleged that the detaining state, Pub, has not complied with a provision of UNCLOS that provides for prompt release upon the posting of a reasonable bond or other financial security. Third, the application can be made by or on behalf of the flag state, which Tavern intends to do (United Nations, 1982).
The key question is whether Pub has violated a provision that mandates prompt release. Article 292 does not create a right to release itself but provides a remedy where such a right, found elsewhere in the Convention, is breached. The most cited example is Article 73(2), which requires the prompt release of vessels arrested for fisheries violations within a state's Exclusive Economic Zone (EEZ) upon the posting of a reasonable bond. However, the facts here do not concern a fisheries violation in Pub’s EEZ; the alleged crime is drug smuggling, and the capture occurred on the high seas.
Despite this, the scope of Article 292 is not necessarily limited to violations of Article 73. The Tribunal in The "Juno Trader" Case confirmed that the application of Article 292 is not restricted to a specific list of provisions (ITLOS, 2004). ITLOS held that an application could be founded on the allegation that the bond or security required by the detaining state is unreasonable. Furthermore, if the domestic law of the detaining state provides for release on bond, an unreasonable failure to apply that law could also trigger an Article 292 application. Therefore, Tavern can allege that Pub's failure to offer release on a reasonable bond is a violation of the general principles of UNCLOS that underpin the prompt release procedure. The purpose of this procedure is to balance the interests of the coastal state in enforcing its laws with the flag state's interest in freeing its vessel and crew from prolonged detention before a final judgment on the merits of the case (Tanaka, 2019). Given this, Tavern has a strong basis to initiate proceedings before ITLOS.
The Legality of the Initial Capture and Subsequent Detention
To understand the current situation, it is necessary to separate the legality of the initial capture from the legality of the continued detention. The vessel was captured on the high seas, an area where the principle of freedom of navigation is paramount under Article 87 of UNCLOS. A warship's right to interfere with a foreign-flagged vessel on the high seas is strictly limited by Article 110 (the right of visit) to exceptional cases such as piracy, the slave trade, or if the vessel is without nationality. None of these apply here. Another exception is the right of hot pursuit under Article 111, which allows a state to pursue a vessel from its waters onto the high seas if it has good reason to believe the vessel has violated its laws. However, the facts state the capture occurred "just outside" the EEZ, and there is no information to suggest a pursuit began within Pub’s maritime zones for a crime committed therein.
The crucial context is that the capture took place during an armed conflict between Tavern and Pub. In such circumstances, the ordinary rules of the law of the sea are supplemented by international humanitarian law. As a belligerent, Pub’s warship was entitled to capture an enemy merchant vessel on the high seas (Shaw, 2017). Since the fishing vessel was flagged to Tavern, it would be classified as an enemy vessel, making its capture lawful at that time.
However, the legal basis for the detention changed significantly. The armed conflict has ended, which would normally require the repatriation of civilians and the release of captured civilian property. Instead of releasing the vessel and crew, Pub is now detaining them on the basis of its domestic criminal law after discovering opium and obtaining a confession. This shifts the legal framework from the law of armed conflict back to the law of the sea. Pub is asserting criminal jurisdiction over an offence discovered on a foreign vessel on the high seas. Under Article 92 of UNCLOS, the flag state has exclusive jurisdiction over its ships on the high seas. While exceptions exist, for example under the "effects doctrine" where a state claims jurisdiction over acts intended to produce harmful effects within its territory, this is a contested area of international law.
The ITLOS proceedings under Article 292 are, importantly, "without prejudice to the merits" of any domestic case. The Tribunal will not decide whether Pub has jurisdiction to prosecute for smuggling or whether the crew is guilty. The sole issue is whether the vessel and crew should be released pending trial, upon the posting of a reasonable security. Tavern’s argument would be that the continued detention without the possibility of release is unreasonable. This argument is strengthened by the humanitarian circumstances: Dr. Martyr's heart attack and his wife's death. The Tribunal has previously shown that it considers the balance of interests, which includes the need to prevent the unreasonable and lengthy detention of individuals whose guilt has not yet been proven (The M/V "SAIGA" (No. 2) Case, 1999).
Conclusion: The Attainability of the Release Order
An order for the release of Dr. Martyr’s vessel and crew is attainable, but not guaranteed. Tavern has a clear procedural path to bring the case before ITLOS under Article 292 of UNCLOS. The main challenge will be to persuade the Tribunal that Pub has breached an obligation under the Convention to provide for prompt release.
The argument in favour of release is compelling. The original legal basis for detention, the armed conflict, no longer exists. The continued detention is based on a domestic criminal charge, but this does not give the detaining state an absolute right to hold a foreign vessel and its crew indefinitely without trial. By refusing to consider release upon the posting of a bond, Pub is arguably failing to respect the balance of interests that underlies the UNCLOS framework, which seeks to protect both coastal state enforcement rights and flag state navigation rights. The severe humanitarian situation would add considerable weight to Tavern's plea for release.
Conversely, Pub will argue that the seriousness of the alleged crime, drug smuggling, justifies the continued detention. Unlike a minor fisheries offence, drug trafficking is viewed as a major international crime, and tribunals may be less inclined to order a release that could be seen as hampering a state’s ability to combat it. Pub could also argue that its domestic law does not permit release on bond for such serious offences, although this would be subject to the Tribunal's assessment of its reasonableness in the context of international law.
On balance, ITLOS is likely to find that a release order is appropriate. It would probably not order an unconditional release but would instead direct Pub to set a "reasonable bond or other financial security" as a condition for the release of the vessel and the remaining crew members. This approach would respect Pub’s right to pursue its criminal case while upholding the principle of prompt release and preventing disproportionate harm to the individuals and the flag state. Therefore, the order Tavern seeks is attainable, with the likely outcome being a conditional release pending the resolution of the criminal proceedings in Pub.
