The Anglo-Iranian Oil Company case had been submitted to the Court by the United Kingdom Government on May 26th, 1951, and had been the subject of an Objection on the ground of lack of jurisdiction by the Government of Iran.
By nine votes against five, the Court declared that it lacked jurisdiction. The Judgment was followed by a separate opinion by Sir Arnold McNair, President of the Court, who while concurring in the conclusion reached in the Judgment for which he had voted, added some reasons of his own which had led him to that conclusion. The Judgment was also followed by four dissenting opinions by fudges Alvarez, Hackworth, Read and Levi Carneiro.
On July 5th, 1951, the Court had indicated interim measures of protection in this case, pending its final decision, stating expressly that the question of the jurisdiction of the merits was in no way prejudged. In its Judgment, the Court declared that the Order of July 5th, 1951, ceased to be operative and that the provisional measures lapsed at the same time.
