The treaty, stipulating that a murderer shall be delivered up to justice, is as obligatory as an act of Congress making the same declaration. If, then, there was an act of Congress in the words of the treaty, declaring that a person who had committed murder within the jurisdiction of Britain, and sought an asylum within the territory of the United States, should be delivered up by the United States, on the demand of His Britannic Majesty, and such evidence of his criminality, as would have justified his commitment for trial, had the offence been here committed; could the President, who is bound to execute the laws, have justified the refusal to deliver up the criminal, by saying, that the Legislature had totally omitted to provide for the case.
The Executive is not only the constitutional department, but seems to be the proper department to which the power in question may most wisely and most safely be confided.
The department which is intrusted with the whole foreign intercourse of the nation, with the negotiation of all its treaties, with the power of demanding a reciprocal performance of the article, which is accountable to the nation for the violation of its engagements with foreign nations, and for the consequences resulting from such violation, seems the proper department to be intrusted with the execution of a national contract like that under consideration.
If, at any time, policy may temper the strict execution of the contract, where may that political discretion be placed so safely as in the department whose duty it is to understand precisely the state of the political intercourse and connection between the United States and foreign nations, to understand the manner in which the particular stipulation is explained and performed by foreign nations, and to understand completely the state of the Union?
This department, too, independent of judicial aid, which may, perhaps, in some instances, be called in, is furnished with a great law officer, whose duty it is to understand and to advise when the casus fœderis occurs. And if the President should cause to be arrested under the treaty an individual who was so circumstanced as not to be properly the object of such an arrest, he may perhaps bring the question of the legality of his arrest before a judge, by a writ of habeas corpus.
It is then demonstrated, that, according to the principles of the American Government, the question whether the nation has or has not bound itself to deliver up any individual, charged with having committed murder or forgery within the jurisdiction of Britain, is a question the power to decide which rests alone with the Executive Department.
It remains to inquire whether, in exercising this power, and in performing the duty it enjoins, the President has committed an unauthorized and dangerous interference with judicial decisions.
That Thomas Nash was committed originally at the instance of the British Consul at Charleston, not for trial in the American courts, but for the purpose of being delivered up to justice in conformity with the treaty between the two nations, has been already so ably argued by the gentleman from Delaware, that nothing further can be added to that point. He would therefore, Mr. Marshall said, consider the case as if Nash had been delivered up instead of having been committed for trial. Admitting even this to have been the fact, the conclusions which have been drawn from it were by no means warranted.
Gentlemen had considered it as an offence against judicial authority, and a violation of judicial rights, to withdraw from their sentence a criminal against whom a prosecution had been commenced. They had treated the subject as if it was the privilege of courts to condemn to death the guilty wretch arraigned at their bar, and that to intercept the judgment was to violate the privilege. Nothing can be more incorrect than this view of the case. It is not the privilege, it is the sad duty of courts to administer criminal judgment. It is a duty to be performed at the demand of the nation, and with which the nation has a right to dispense. If judgment of death is to be pronounced, it must be at the prosecution of the nation, and the nation may at will stop that prosecution. In this respect the President expresses constitutionally the will of the nation; and may rightfully, as was done in the case at Trenton, enter a nolle prosequi, or direct that the criminal be prosecuted no farther. This is no interference with judicial decisions, nor any invasion of the province of a court. It is the exercise of an indubitable and a constitutional power. Had the President directed the Judge of Charleston to decide for or against his own jurisdiction, to condemn or acquit the prisoner, this would have been a dangerous interference with judicial decisions, and ought to have been resisted. But no such direction has been given, nor any such decision been required. If the President determined that Thomas Nash ought to have been delivered up to the British Government for a murder committed on board a British frigate, provided evidence of the fact was adduced, it was a question which duty obliged him to determine, and which he determined rightly. If, in consequence of this determination, he arrested the proceedings of a court on a national prosecution, he had a right to arrest and to stop them, and the exercise of this right was a necessary consequence of the determination of the principal question. In conforming to this decision, the court has left open the question of its jurisdiction. Should another prosecution of the same sort be commenced, which should not be suspended but continued by the Executive, the case of Thomas Nash would not bind as a precedent against the jurisdiction of the court. If it should even prove that, in the opinion of the Executive, a murder committed on board a foreign fleet was not within the jurisdiction of the court, it would prove nothing more; and though this opinion might rightfully induce the Executive to exercise his power over the prosecution, yet if the prosecution was continued, it would have no influence with the court in deciding on its jurisdiction.
Taking the fact, then, even to be as the gentlemen in support of the resolutions would state it, the fact cannot avail them.
