Por lo que pude ver el fallo fue unánime y ordena la liberación de la fragata en forma incondicional. Además, entre otros acápites, especifica que se le debe permitir reaprovisionarse (para que pueda abandonar el puerto).
La parte medular del fallo:
(1) Unanimously,
Prescribes , pending a decision by the Annex VII arbitral tribunal, the following provisional measures under article 290, paragraph 5, of the Convention: Ghana shall forthwith and unconditionally release the frigate ARA Libertad, shall ensure that the frigate ARA Libertad, its Commander and crew are able to leave the port of Tema and the maritime areas under the jurisdiction of Ghana, and shall ensure that the frigate ARA Libertad is resupplied to that end.
