A request for the prescription of provisional measures under article 290, paragraph 5, of the United Nations Convention on the Law of the Sea has been submitted to the International Tribunal for the Law of the Sea in a dispute between Switzerland and Nigeria concerning the arrest and detention of the M/T “San Padre Pio”, its crew and cargo. According to the Request of Switzerland of 21 May 2019, the “San Padre Pio”, a motor tanker flying the flag of Switzerland, “was intercepted and arrested by the Nigerian Navy on 23 January 2018” while it was engaged in ship-to-ship transfers of gasoil in the exclusive economic zone (EEZ) of Nigeria. The vessel was then ordered to proceed to Port Harcourt (Nigeria), where it is still detained. Switzerland submits that Nigeria has “breached its obligations owed to Switzerland in regard to its freedom of navigation and its right to exercise exclusive jurisdiction over the “San Padre Pio””. The request is available here.
