The Saiga was a tanker flying the Saint Vincent and the Grenadines (plaintiff) flag. The tanker was supplying oil to fishing boats off the coast of Guinea (defendant) when Guinean authorities attacked the vessel and arrested its captain. Guinea convicted the captain of violating Guinean customs laws. Saint Vincent and the Grenadines filed a claim with the International Tribunal for the Law of the Sea, asserting that Guinea unlawfully interfered with its navigation rights. Guinea claimed, among other things, that it was not required to recognize the Vincentian nationality of the vessel, because there was not a genuine link between the vessel and Saint Vincent and the Grenadines. As a result, according to Guinea, Saint Vincent and the Grenadines’s claim was inadmissible.
