It has also been contended that the question of jurisdiction was decided at Trenton, by receiving indictments against persons there arraigned for the same offence, and by retaining them for trial after the return of the habeas corpus.

Every person in the slightest degree acquainted with judicial proceedings, knows that an indictment is no evidence of jurisdiction; and that, in criminal cases, the question of jurisdiction will seldom be made but by arrest of judgment after conviction.

The proceedings, after the return of the habeas corpus, only prove that the case was not such a case as to induce the Judge immediately to decide against his jurisdiction. The question was not free from doubt, and, therefore, might very properly be postponed until its decision should become necessary.

It has been argued by the gentleman from New York, that the form of the indictment is, itself, evidence of a power in the court to try the case. Every word of that indictment, said the gentleman, gives the lie to a denial of the jurisdiction of the court.

It would be assuming a very extraordinary principle, indeed, to say that words inserted in an indictment for the express purpose of assuming the jurisdiction of a court, should be admitted to prove that jurisdiction. The question certainly depended on the nature of the fact, and not on the description of the fact. But as an indictment must necessarily contain formal words in order to be supported, and as forms often denote what a case must substantially be to authorize a court to take cognizance of it, some words in the indictments at Trenton ought to be noticed. The indictments charge the persons to have been within the peace, and murder to have been committed against the peace, of the United States. These are necessary averments, and, to give the court jurisdiction, the fact ought to have accorded with them. But who will say that the crew of a British frigate on the high seas, are within the peace of the United States? or a murder committed on board such a frigate, against the peace of any other than the British Government?

It is, then, demonstrated that the murder with which Thomas Nash was charged, was not committed within the jurisdiction of the United States, and, consequently, that the case stated was completely within the letter and the spirit of the twenty-seventh article of the treaty between the two nations. If the necessary evidence was produced, he ought to have been delivered up to justice. It was an act to which the American nation was bound by a most solemn compact. To have tried him for the murder would have been mere mockery. To have condemned and executed him, the court having no jurisdiction, would have been murder. To have acquitted and discharged him would have been a breach of faith, and a violation of national duty.

But it has been contended that, although Thomas Nash ought to have been delivered up to the British Minister, on the requisition made by him in the name of his Government, yet, the interference of the President was improper.

This, Mr. M. said, led to his second proposition, which was:

That the case was a case for Executive and not Judicial decision. He admitted implicitly the division of powers, stated by the gentleman from New York, and that it was the duty of each department to resist the encroachments of the others.

This being established, the inquiry was, to what department was the power in question allotted?
