upon the view expressed by my brother Isaacs in Whybrow's
Case 1, namely, that prohibition is an exercise of appellate juris- diction (in support of which a passage, or rather a footnote, in vol. IX. of Halsbury's Laws of England, p. 59, was cited), and [No. 1].
that it has therefore been taken away by excepting it from the appellate jurisdiction of the High Court.
In my opinion the jurisdiction of the superior Courts in Eng- land to grant the common law writ of prohibition was original and not appellate jurisdiction. An examination of "the origin and reason of the writ" as well as "the history of the procedures by which it has at different times been enforced," to use the words of Brett J. in Worthington v. Jeffries 2, seems to put this beyond controversy. As was pointed out by Willes J. in his great opinion in Mayor &. of London v. Cox 3 All lawful jurisdiction is derived from and must be traced to the royal authority. Any exercise, however fitting it may appear, of juris- diction not SO authorized, is an usurpation of the prerogative, and a resort to force unwarranted by law. Upon both grounds, viz., the infringement of the prerogative, and the unauthorized pro- ceeding against the individual, prohibitions by law are to be granted, at any time, to restrain a Court to intermeddle with or execute anything which by law they ought not to hold plea of, and they are much mistaken that maintain the contrary." The last sentence is from Articuli Cleri, 2 Inst., 602.
In Worthington v. Jeffries 4 Brett J. proceeded to say :- "These authorities show that the ground of decision, in con- sidering whether prohibition is or is not to be granted, is not whether the individual suitor has or has not suffered damage, but is, whether the royal prerogative has been encroached upon by reason of the prescribed order of administration of justice having been disobeyed. If this were not so, it seems difficult to under- stand why a stranger may interfere at all."
We all know that the Court of King's Bench was never a Court of appeal from the Ecclesiastical Courts, to which in ancient times prohibitions were most commonly directed, or, indeed, from any other inferior Court to which the writ lay. It might be
