The amendments subsequently made to this article have no bearing upon the question under consideration, nor is it necessary to examine the various acts of Congress conferring jurisdiction upon the courts of the United States, for no act of Congress can be found extending the jurisdiction beyond what is given by the constitution, so far as relates to the question we are now considering. And if such an act should be passed it would be in direct conflict with the tenth amended article of the constitution, which declares that “the powers not delegated to the United States by the constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.”

If this case can be brought within the judicial power of the courts of the United States, it must be either—

1st. Because it arises under the Constitution or the laws of the United States.

Or, 2d. Because it is a controversy between citizens of different States, for it is very plain that there is no other clause in the Constitution which, by the most latitudinarian construction, could be made to include it.

Did it arise under the Constitution or the laws of the United States? In order to give a satisfactory answer to this question, it is necessary to see what the case was.

If we confine ourselves strictly to the record from the district court, we learn from it that, on the 18th day of July last, John H. Wheeler presented his petition to the Hon. J. K. Kane, judge of the district court for the eastern district of Pennsylvania, setting forth that he was the owner of three persons held to service or labor by the laws of the State of Virginia; such persons being respectively named Jane, aged about thirty-five years, Daniel, aged about twelve years, and Isaiah, aged about seven years, persons of color; and that they were detained from his possession by Passmore Williamson, but not for any criminal or supposed criminal matter. In accordance with the prayer of the petition, a writ of habeas corpus was awarded, commanding Passmore Williamson to bring the bodies of the said Jane, Daniel, and Isaiah, before the judge of the district court, forthwith. To this writ, Passmore Williamson made a return, verified by his affirmation, that the said Jane, Daniel, and Isaiah, nor either of them, were at the time of the issuing of the writ, nor at the time of the return, nor at any other time, in the custody, power, or possession of, nor confined, nor restrained their liberty by him; and that, therefore, he could not produce the bodies as he was commanded.

This return was made on the 20th day of July, A. D. 1855. “Whereupon, afterwards, to wit: On the 27th day of July, A. D. 1855, (says the record,) the counsel for the several parties having been heard, and the said return having been duly considered, it is ordered and adjudged by the court that the said Passmore Williamson be committed to the custody of the marshal, without bail or mainprize, as for a contempt in refusing to make return to the writ of habeas corpus, heretofore issued against him, at the instance of Mr. John H. Wheeler.”

Such is the record. Now, while I am willing to admit that the want of jurisdiction should be made clear, I deny that in a case under our habeas corpus act the party averring want of jurisdiction cannot go behind the record to establish its non-existence. Jurisdiction, or the absence thereof, is a mixed question of law and fact. It is the province of fact to ascertain what the case is, and of law to determine whether the jurisdiction attaches to the case so ascertained. “And” says the second section of our act of 1785, “that the said judge or justice may, according to the intent and meaning of this act, be enabled, by investigating the truth of the circumstances of the case, to determine whether, according to law, the said prisoner ought to be bailed, remanded, or discharged, the return may, before or after it is filed, by leave of the said judge or justice, be amended, and also suggestions made against it, so that thereby material facts may be ascertained.”

This provision applies to cases of commitment or detainer for any criminal or supposed criminal matter, but the fourteenth section, which applies to cases of restraint of liberty “under any color or pretence whatever,” provides that “the court, judge, or justice, before whom the party so confined or restrained shall be brought, shall, after the return made, proceed in the same manner as is hereinbefore prescribed, to examine into the facts relating to the case, and into the cause of such confinement or restraint, and thereupon either bail, remand, or discharge the party so brought, as to justice shall appertain.”

The right and duty of the supreme court of a State to protect a citizen thereof from imprisonment by a judge of a United States court having no jurisdiction over the cause of complaint, is so manifest and so essentially necessary under our dual system of government, that I cannot believe that this right will ever be abandoned or the duty avoided; but, if we concede, what appears to be the law of the later cases in the Federal courts, that the jurisdiction need not appear affirmatively, and add to it that the want of jurisdiction shall not be proved by evidence outside of the record, we do virtually deny to the people of the State the right to question the validity of an order by a Federal judge consigning them to the walls of a prison “without bail or mainprize.”
