… However, we have no evidence that the United States actually undertook negotiations on an agreement on sea turtle conservation techniques which would have included the complainants before the imposition of the import ban as a result of the CIT judgement. From the replies of the parties to our question on this subject, in particular that of the United States, we understand that the United States did not propose the negotiation of an agreement to any of the complainants until after the conclusion of negotiations on the Inter-American Convention for the Protection and Conservation of Sea Turtles, in September 1996, i.e. well after the deadline for the imposition of the import ban of 1 May 1996. Even then, it seems that the efforts made merely consisted of an exchange of documents. We therefore conclude that, in spite of the possibility offered by its legislation, the United States did not enter into negotiations before it imposed the import ban. As we consider that the measures sought by the United States were of the type that would normally require international cooperation, we do not find it necessary to examine whether parties entered into negotiations in good faith and whether the United States, absent any result, would have been entitled to adopt unilateral measures. （emphasis added）
