This question came up for decision shortly after the adoption of the Constitution. Great Britain and Spain were at war. A British man-of-war brought a Spanish felucca into Charleston, claiming her as a prize, and she was advertised for sale. No proceedings to have her adjudicated a lawful prize had been taken before any court. The Spanish consul applied to the Circuit Court for an injunction against the sale, claiming that for the United States to permit it would be a breach of neutrality and contrary to the law of nations. The British consul resisted the application on the ground that a sale could not be forbidden in the absence of any act of Congress on the subject, except by the President. The Chief Justice, who sat in the case, gave the opinion, which was that there could be no lawful sale without the permission of the United States; that it was a matter proper to be dealt with by the President; that the court would not say how he should deal with it; but that an injunction might issue to stop the sale until further order, unless permission should be sooner obtained from the President.[Footnote: Consul of Spain v. Consul of Great Britain, Bee's Reports, 263.] Here, therefore, an act which might have been a casus belli was stayed by a court until and unless the Executive should intervene and permit it.

The extradition of criminals under a treaty on the demand of a foreign government presents a debatable ground in respect to the subject now under consideration. The surrender is an executive proceeding and a political act. But the laws may provide for a preliminary inquiry before a court into the propriety of complying with the demand. They certainly provide for a judicial proceeding by writ of habeas corpus to release any one arrested in such a proceeding if held without due cause. Is the court before which either of these proceedings may be had at liberty to receive advice or submit to instructions from the President of the United States?

This question stirred the country to its depths in 1799. Great Britain applied to our government for the extradition of a seaman who claimed to be an American citizen and was charged with committing murder on a British man-of-war. He was arrested in South Carolina, under a warrant from the District Judge, and lodged in jail. There was a treaty of extradition between the two powers covering cases of murder, but no particular machinery had been provided for regulating the surrender. The British consul asked the judge who had made the commitment to order his delivery to him. The judge doubted his power to do so. Thereupon the Secretary of State, by authority of the President, wrote him that the President advised and requested him to make the surrender, if satisfied with the proofs of criminality, as he (the President) was of opinion that any crime committed on a man-of-war was committed within the territory of the power to which it belonged. The judge complied with this request, after a public hearing on a writ of habeas corpus, under which he ordered the man in question to be brought before him, and in the course of it this letter was shown to counsel on both sides.

The surrender became at once the subject of heated debates in Congress, but the President's course was ably and conclusively defended by Marshall on the floor of the House,[Footnote: United States v. Nash alias Robins, Bee's Reports, 266; Robbins' Case, Wharton's State Trials, 392.] and the course pursued has since been followed in substance by our extradition statutes.[Footnote: United States Revised Statutes, Secs. 5270, 5272.] These provide for a hearing of a judicial character, and then, if that results in a determination that a surrender should be made, it may be ordered on a warrant from the State Department.

On the other hand, the peculiar provision of the Constitution of the United States which makes treaties the supreme law of the land calls upon the courts to enforce them according to whatever interpretation they may conclude to give them, even if it should differ from that adopted by the President or the State Department. If a treaty prescribes a rule by which the rights of private individuals are to be determined, and those rights are such as can be appropriately made the subject of a lawsuit, the court before which it may be brought has as full authority to construe the treaty as it would have to construe an act of Congress, were the matter in controversy one of a statutory nature. They cannot be appropriately made the subject of a lawsuit so long as the questions involved are under active consideration in the course of diplomatic negotiation and pending for decision before the President. Let him, however, once make his decision and the doors of the court fly open.

These principles are well illustrated by some incidents of our controversy with Great Britain over the seal fisheries in Behring Sea. There was a serious dispute between the two governments as to the limits of our jurisdiction over the waters adjacent to Alaska. We maintained that it ran to the middle of Behring's Straits and from the meridian of 172° to that of 193° west longitude. Great Britain contended for the three-mile limit. Pending diplomatic negotiations as to this point, one of our revenue cruisers seized a Canadian vessel which was engaged in seal fishing nearly sixty miles from the Alaskan coast, and she was condemned, on a libel by the United States, by an admiralty court in Alaska.

The owner in 1891 applied to the Supreme Court of the United States for a writ to prohibit the enforcement of this decree of confiscation. The Attorney-General of Canada filed in this suit papers in aid of the application, stating that he did so with the knowledge and approval of the imperial government, and that he would be represented by counsel employed by the British minister resident. The writ was refused on technical grounds, but the court, through Chief Justice Fuller, made these observations as to the merits of the cause:

In this case, Her Britannic Majesty's Attorney-General of Canada has presented, with the knowledge and approval of the Imperial government of Great Britain, a suggestion on behalf of the claimant. He represents no property interest in the vessel, as is sometimes done by consuls, but only a public political interest. We are not insensible to the courtesy implied in the willingness thus manifested that this court should proceed to a decision on the main question argued for the petitioner; nor do we permit ourselves to doubt that under such circumstances the decision would receive all the consideration that the utmost good faith would require; but it is very clear that, presented as a political question merely, it would not fall within our province to determine it…. We are not to be understood, however, as underrating the weight of the argument that in a case involving private rights, the court may be obliged, if those rights are dependent upon the construction of acts of Congress or of a treaty, and the case turns upon a question, public in its nature, which has not been determined by the political departments in the form of a law specifically settling it, or authorizing the executive to do so, to render judgment, "since we have no more right to decline the jurisdiction which is given than to usurp that which is not given."[Footnote: In re Cooper, 143 United States Reports, 472, 503.]

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:
