(after stating tbe case), delivered tbe opinion of the"’ court.
The first question is, whether, on tbe facts appearing by tbe return, tbe case is a proper one to be considered on habeas corpus.
It is a well-established and undisputed principle that mere errors in tbe proceedings of a court of competent jurisdiction cannot be reviewed on habeas corpus. In such case tbe remedy, if any, is by writ of error or appeal. But where tbe proceedings under which tbe party complaining is detained in custody are void, as where tbe court is without jurisdiction, tbe same are reviewable on habeas corpus, and tbe party will be discharged.
“If it appear,” says Lord Hale, “by the return of tbe writ that tbe party be wrongfully committed, or by one that, bath not jurisdiction, or for a cause for which a man ought not to be imprisoned, be shall be discharged.” Bac. Abr., Habeas corpus, B-10; Hurd on Habeas corpus, 333.
It was on this ground that tbis court proceeded in ex-parte Meredith, 33 G-ratt. 119, though tbe proceeding was really an amicable one to determine the title to the office of county judge of Prince "William county. And the same principle is illustrated by numerous decisions of the Supreme Court of tbe Hnited States.
Thus, in ex parte Lange, 18 "Wall. 163, tbe petitioner was discharged on habeas carpus on tbe ground that be was illegally restrained of bis liberty by virtue of a void judgment of a *317Federal court. See also ex parte Siebold, 100 U. S. 871; ex parte Wilson, 114 Id. 417.
On tbe other hand, in ex parte Watkins, 3 Pet. 193, the writ was refused, because the petitioner was in custody under the order of a court of competent jurisdiction, which was therefore conclusive on all other courts. So, on the same ground, the court refused to interfere in the following cases: ex parte Kearney, 7 Wheat. 38; ex parte Parks, 93 U. S. 18; ex parte Virginia, 100 Id. 339; ex parte Curtis, 106 Id. 371; expiarte Yarbrough, 110 Id. 651; ex parte Crouch, 112 Id. 178; ex parte Bigelow, 113 Id. 328.
In ex parte Siebold, supra, the writ was applied for to discharge the petitioner from custody, who had been indicted and convicted in the Circuit Court of the United States for the district of Maryland, under certain acts of Congress which were alleged to be unconstitutional. And the question arose, whether the court had jurisdiction to discharge a party imprisoned under sentence of a United States court upon a conviction of a crime created by and indictable under an unconstitutional act of Congress; and it was held that it had.
“The validity of the judgment,” said the court, “is assailed on the ground that the acts of congress, under which the indictment was found, are unconstitutional. If this position is well taken, it affects the foundation of the whole proceedings. An unconstitutional law is void, and is as no law. • An offence created by it is not a crime. A conviction under it is not merely erroneous, but illegal and void, and cannot be a legal cause of imprisonment. * * We are satisfied that the present is one of the cases in which this court is authorized to take jurisdiction. We think so, because, if the laws are unconstitutional and void, the circuit court acquired no jurisdiction of the case.”
The principle there asserted fully sustains the jurisdiction of this court in the present case. There, it is true, the imprisonment complained of was by virtue of a final judgment in a criminal prosecution; here it is under original process in a civil *318action. But the principle is in both cases the same. Formerly it was doubted whether habeas corpus was a proper remedy in case of arrest under civil process. Ex parte Wilson, 6 Cranch, 52. But such doubt, from whatever source it may have arisen, is no longer entertained.
In Nelson Graydon v. Cutter, 3 McLean, 326, the defendants in a civil action were discharged on habeas corpus, on the ground that the affidavit was insufficient upon which the capias ad res-pondendum issued under which they had been arrested. And according to the rule acted on in that and similar cases, the true test is, whether the process is illegal and void, or irregular merely. If the former, then the party in custody is restrained of his liberty without due process of law, and is entitled to the immediate remedy of habeas corpus; but not so in the latter case. Ex parte Randolph, 2 Brock. 447, 475; ex piarte Rowland, 104 U.S, 604; Rank U.S. v. Jenkins, 18 Johns. 305; Bac. Abr. Habeas corpus, B, 3.
The next question, then, is whether the provisions of the revenue laws, the validity of which is questioned in the present ease, are, as alledged, unconstitutional. And upon this point there would seem to be no room for doubt, in view of several recent decisions of the Supreme Court of the United States.
In Webber v. Virginia, 103, U. S. 344, certain provisions of the revenue laws of this state, imposing a tax on the privilege of selling the manufactured articles or machines of other states or territories — there being no such tax imposed on the privilege of selling the manufactured articles or machines of this state— were held invalid, because repugnant to. that clause of the Federal constitution which gives to congress the power to regulate commerce among the several states.
In the present case, the evident purpose of the legislature in enacting the sections of the statute in question .was to discriminate in fkvor of the publishers of books, newspapers, periodicals, etc., in this state, and against those engaged in such business elsewhere.. Thus all persons, other than licensed merchants, *319who receive subscriptions for, or in any manner furnish, books, newspapers, periodicals, etc., published beyond the limits of this state, are required to pay a license-tax, while no such tax is imposed for the privilege of selling the publications of this state. This is in effect imposing a tax on the publications of other states, and is to that extent a regulation of commerce in such publications between the states, and, therefore, in conflict with the constitution of the United States.
In Webber v. Virginia, supra, Mr. Justice Field, speaking for the court, said: “ Sales by manufacturers are chiefly effected through agents. A tax upon their agents when thus engaged is, therefore, a tax upon them, and if this is made to depend upon the foreign character of the articles, that is upon their having been manufactured without the state, it is to thakextent a regulation of commerce in the articles between the states. It matters not whether the tax be laid directly upon the articles sold, or in the form of licenses for their sale. If by reason of their foreign character the state can impose a tax upon them, or upon the person through whom the sales are effected, the amount of the tax will be a matter resting in her discretion. She may place the tax at so high a figure as to exclude the introduction of the foreign article, and prevent competition with the home product. It was against legislation of this discriminating kind that the framers of the constitution intended to guard when they vested in Congress the power to regulate commerce among the several states.” See also Welton v. Missouri, 91 U. S. 275; County of Mobile, v. Kimball, 102 Id. 691; Brown v. Houston, 114 Id. 622; Walling v. Michigan, 116 Id. 446.
The ruling in those cases is decisive of this. The books, newspapers, periodicals, etc., printed or published beyond the limits of the state, and for the sale of which a license-tax is imposed by the revenue laws, stand on the same footing in this particular with the manufactured articles and machines of other states or territories. All are alike articles of commerce, and *320as such equally protected against discriminating regulations by authority of state legislation.
It follows that the petitioner is illegally in custody, and an order for his discharge will be entered accordingly.
