The writ of habeas applied for here was not a writ of course, though a writ of right. It had to be moved for, and a proper case had to be shown. No writ was ever issued, but where a writ may be issued, the Court, under the rules, may act promptly as if the writ had been issued, the issue of the writ being treated as an unnecessary formality. In order, however, to see whether the Court had jurisdiction to issue the writ, the nature of the case as it appears before the Court has to be examined. That is so, because, as stated by Lord Chief Justice Wilmot in his opinion to the House of Lords[26], on the writ of habeas the Court "inquires after the cause of his imprisonment." If on the application - and it may be ex parte - the right is clear or even probable, the writ may issue. The return, however, may set up facts which, if true, show that the person brought up must not be discharged, because, inter alia, the matter relied on cannot be inquired into by the Court. But if, as here, no writ is issued, but an order nisi is granted, and on its return it clearly appears on the inquiry into the cause of imprisonment that the matter relied on is not within the competency of the Court to determine, the Court has no legal power to issue the writ, and its decision to the contrary is unauthorized and appealable. It is, in that case, a misuse of language to call it a "competent Court." The very condition stated in the House of Lords cases referred to, namely, that the discharging Court must be "competent" in order to prevent appeal under the general power of appeal, shows that its own view as to its competency does not, if that be challenged, finally determine the matter, but is examinable by an appellate tribunal. That is the vital factor in this problem, and the respondent's argument entirely overlooks it. But whether the want of jurisdiction appears at once or only at a later stage, the moment it does appear the Court dealing with the habeas application is incompetent to discharge the applicant, and must hold its hand. Lord Chief Justice Wilmot laid down the law on this point, with illustrations, in the most lucid manner. At p. 122 of the work quoted, in exemplification of the principle that the Court in habeas has no jurisdiction to substitute its own determination of the governing facts and law for the different method prescribed by law for their determination, whatever that other method may be, the Lord Chief Justice says: - "Suppose an action brought upon a bond for any given sum of money, and the party is arrested upon it, and he pleads that he never executed the bond; suppose he could show by affidavits ever so clearly, that he did not execute the bond, or, by a copy of the Register, that he was not born when it is dated. The Court could not interpose; why? Because the law says, the fact must be tried by a jury: the Judges have no more cognizance or power to try it than if they were not Judges." Yet the applicant here would say that the Judges, if they disregarded the law and ordered the discharge, were for that purpose "a competent Court"! And be it noted, the Lord Chief Justice was speaking of the Court of King's Bench and the other English superior Courts, whose authority the Supreme Court of the Territory inherits. Wilmot C.J. gives another instance[27]: - "If a man is arrested and in custody, in a civil action, ... the Court will not, even for the purpose of discharging him out of custody, enter into any examination of the reality of the debt, though there is the most clear and undoubted proof laid before the Court of the falsity of the demand; it must be tried by a jury. The Court cannot look at it." With reference to the case of a recruit claiming release from habeas when about to be sent abroad for service, the Lord Chief Justice observes[28]: "If the case was ever so remediless, I think we are not warranted to impeach, by affidavits, the truth of the return of an officer, acting under an Act of Parliament, which the law says ought to be impeached by a verdict."
