The conflict between some western States and Iran has reached a new phase. Last month, both sides arrested tankers off their coasts. Whereas the political intentions of either side are evident, difficult questions come up with regard to the legal assessment of these actions. They concern the extraterritorial application of a sanction regime, the law of the sea and countermeasures. The post will describe the facts related to the detention of a tanker off Gibraltar (1). It will be investigated if the regime of the transit passage (2) or of innocent passage (3) is applicable under the UN Convention on the Law of the Sea (UNCLOS). Thereafter, the post will study which State may rely on the respective rights (4). The post then will turn to the facts of the second case which happened in the strait of Hormuz (5). It will shortly mention Iran’s right to take measures for the safety of navigation beyond its territorial waters (6), and the regime of countermeasures (7). In part (8) the compatibility of military patrols by western States in the strait of Hormuz with the law of the sea will be studied.
The Facts related to the case off the coast of Gibraltar
On July 4, 2019 the British navy detained the tanker Grace 1, allegedly in the territorial waters of Gibraltar. The vessel was passing through the strait of Gibraltar after having circumnavigated Africa. The chief minister of Gibraltar declared in a press release that the vessel was seized in order to enforce EU sanctions against Syria. The decision was based on the EU regulation 36/2012, a law of Gibraltar of 29 March 2019 and a regulation of Gibraltar of 3 July 2019. According to art. 14 para. 2 of the EU regulation it is prohibited to make available economic resources to corporations listed in Annex 2 to the regulation which includes the Banyas Oil Refinery Company. The chief minister of Gibraltar alleged that the oil carried by the tanker came from Iran and was destined to the refinery; this is denied by Iran.
The EU regulation and the above-mentioned legislation of Gibraltar is applicable on the territory of Gibraltar and the territorial waters. Gibraltar claims territorial waters up to 3 nm.
Grace 1 is owned by a shipping company located in Singapore and flew the flag of Panamá. However, according to the Autoridad Marítima de Panamá the vessel was removed from the open registry of Panamá on 29 May 2019.
