In the following year a convention was concluded between the United States and Great Britain for the submission of the question of our jurisdiction over Behring's Sea to arbitration. The arbitration took place and the award supported the British contention. Congress passed an act to give it full effect. The convention provided in terms that "the high contracting parties engage to consider the result of the proceedings of the tribunal of arbitration as a full, perfect and final settlement of all the questions referred to by the arbitrators." In July, 1891, before the award was made, an American vessel engaged in the seal fishery outside the three-mile limit was seized by one of our revenue cutters. A libel was filed by the United States in the admiralty court for Alaska and she was condemned. Her owners appealed to the Circuit Court of Appeals, on the ground that the seizure was made outside of the jurisdiction of the United States. If so, they were entitled to her release. The court held that the limits of this jurisdiction were conclusively settled by the award, and thus adverted to the claim that they should treat the case as the Supreme Court of the United States had dealt with that which followed the seizure of the year before: This question has been settled by the award of the arbitrators, and this settlement must be accepted "as final." It follows therefrom that the words "in the waters thereof," as used in section 1956, and the words "dominion of the United States in the waters of Behring Sea," in the amendment thereto, must be construed to mean the waters within three miles from the shores of Alaska. In coming to this conclusion, this court does not decide the question adversely to the political department of the government. It is undoubtedly true, as has been decided by the Supreme Court, that, in pending controversies, doubtful questions which are undecided must be met by the political department of the government. "They are beyond the sphere of judicial cognizance," and "if a wrong has been done, the power of redress is with Congress, not with the judiciary." The Cherokee Tobacco, 11 Wall., 616-621. But in the present case there is no pending question left undetermined for the political department to decide. It has been settled. The award is to be construed as a treaty which has become final. A treaty when accepted and agreed to becomes the supreme law of the land. ... The duty of courts is to construe and give effect to the latest expression of the sovereign will; hence it follows that, whatever may have been the contention of the government at the time _in re_ Cooper was decided, it has receded therefrom since the award was rendered, by an agreement to accept the same "as a full, complete, and final settlement of all questions referred to by the arbitrators," and from the further fact that the government since the rendition of the
