delivered the opinion of the court.
Section 19 of what is known as the “Auditor’s Agent Act,” approved May 6, 1880, provides:
“In all suits and controversies involving the title to land claimed and held by virtue of a deed executed by the Auditor for non-payment of taxes there ■ on, the person claiming adverse title to such heed shall be required to prove, in order to defeat the title conveyed by such deed, either that the land described therein was not subject to taxation at the date of the assessment of the tax for which it was sold, or that the taxes for the non-payment of which the land was sold were paid to the proper officer within the time limited by law therefor, or that the same has not been assessed for the taxes for the non-payment of which it was sold, or that the same had been redeemed pursuant to law, or that a certificate in proper form had been given by the proper officer within the time limited by law for paying taxes, or redeeming from sales made for the nonpayment thereof, stating that no taxes were due, or that the lands were not subject to redemption; but no person shall be permitted to question the title acquired by such Auditor’s deed without proving that he or the person through whom he claims title had title to the land at the time of the sale thereof for non-payment of taxes, or subsequently, which title was acquired from the State.”
*7The appellant, T. A. Maguiar, purchased the land of the appellee, John Henry, at a tax sale made under said act, obtained the Auditor’s deed to it, and then brought this action to recover it, alleging in substance in his petition that after proper advertisement it was sold by the Auditor, and conveyed by him to the appellant as the purchaser. There is no averment as to an assessment or the other preliminary steps leading to a valid tax sale, save that of advertisement. A general demurrer was sustained to the petition, and the action dismissed.
It is noticeable that the section supra requires a defendant to a suit upon a tax deed to show a title from the Commonwealth before he can deny the plaintiff’s right. It is a general rule that the latter must recover upon the strength of his own title. Here, however, he does not claim under a patent or a grant from the State simply; but under a deed, which purports to divest the defendant of and invest him with the title, and yet the defendant is forbidden to show his right to the property, although it may be sanctified by actual possession for a century, unless he can show a grant from the State to him or those through whom he claims title.
The act imposes upon the owner of land, in order to defeat a tax title, the burden of proving one of five things: either that the property was not subject to the tax; or that it had been paid; or that the land had not been assessed; or had been redeemed; or that the officer has certified that no taxes were due. It cuts off all other defenses..
Three serious questions are presented:
First. Can the Legislature shift the burden of *8proof from the tax claimant to the owner in possession of the property?
Second. If so, yet must not the plaintiff allege in his petition the facts essential to support a tax title ?
Third. Is not the act unconstitutional; at least so far as it undertakes to deprive the owner of material existing defenses?
The laws for the assessment and collection of taxes are necessarily summary in their character. Title is divested by special statute; but it is stricti juris, and must be followed in all material respects. The tax-payer is entitled, by “the law of the land,” to be heard before he is condemned. Magna Charta gave him this right. “No freeman shall be taken or imprisoned, or be disseized of his freehold, or liberties, or free customs, or be outlawed or exiled, or any otherwise destroyed, nor will we pass upon him, nor condemn him, but by lawful judgment of his peers or by the law of the land. We will sell to no man, we will not deny or defer to any man, either justice or right.”
The Constitution of the United States' re-echoes this fundamental rule, so early established, by providing that no person shall be deprived of life, liberty, or property “without due process of law;” while our State Constitution says, “nor can he be deprived of his life, liberty or property unless by the judgment of his peers or the law of the land.”
The legislative power to levy and collect taxes is not arbitrary. The law can not be so framed as to prevent the citizen from inquiring through the courts *9whether there has been a forbidden assumption of legislative power. For instance, a statute denying to him the right in defense of his property to inquire whether a gross inequality of burden has been imposed, or. fraud practiced in the assessment or sale of his property, would be unconstitutional, because it would deprive him of his property without a hearing, and without “due process of law.”
Courts can not thus be deprived of jurisdiction by the Legislature.
If so, one co-equal department of the government could at once destroy the other.
Conceding that the burden of proof may be shifted by a legislative act from the plaintiff to the defendant, as we think it may as a mere regulation of the remedy, provided it does not conflict with a vested right, yet it is questionable whether the act now under consideration does not go farther than this, and require a defendant to make out a cause of action for, or a right in, the plaintiff.
If so, it can not be sustained, because this would, in effect, compel the court to hold that a petition sets out a cause of action when it does not. The section of the act under consideration, however, is clearly unconstitutional, because it limits the owner of the property to certain defenses and cuts off others, which may exist and which are material.
It is true that other sections of the act speak of the Auditor’s deed proving invalid for other causes than those enumerated in section 19; but if it be permissible under the act to show them, then said section is inoperative.
*10We think, however, that it was the intention of the Legislature to cut off the right of the owner of the property to defend against the sale upon any other ground existing prior to it than those enumerated in said section, and this they could not do constitutionally, because it would deprive the defendant of a vested right to an existing material defense.
Cooley, in his Constitutional Limitations, page 368, says: “As to what shall be evidence and who shall assume the burden of proof, its power is unrestricted so long as its rules are impartial and uniform; but it has no power to establish rules which, under pretense of regulating evidence, altogether precludes a party from exhibiting his rights. A statute making a tax deed conclusive evidence of a complete title, and precluding the original owner from showing its invalidity, would, therefore, be void, as not a law regulating evidence, but an unconstitutional confiscation of property.” (Vide Kinnon v. Pope, 1 Gilman, 431; Standenman v. Brown, 48 Ala., 699.)
The Legislature may, by a subsequent statute, cure a mere irregularity in a proceeding if it could have dispensed with it by a prior statute. If it could have been made immaterial at the outset, it may be made .so by a subsequent law.
'But the Legislature has no power, by a subsequent curative statute, to remedy a jurisdictional defect, or one which goes to the substance of a vested right, and thus cut off a vested defense by the usurpation of judicial power. To do so would be to condemn without hearing, and to refuse a party an existing material right.
*11A tax deed can no more be declared by statute to be conclusive as to matters essential to jurisdiction than the finding of an indictment by a grand jury could be by legislative act made conclusive of the defendant’s guilt.
Suppose that the ministerial officer, whose duty it is to collect the tax, fails to advertise the property for sale, or to sell it at the court-house door, or to sell it publicly, or was interested in the purchase, or fraudulently combines with the purchaser so as to sacrifice the property, is the owner to be deprived by a curative statute of his existing vested defense upon these grounds? If so, then it is “without due process of law,” and in violation of “the law of the land.” We unhesitatingly conclude that the act in question, so far as it attempts to deprive the owner of a then existing and material defense, is without constitutional warrant, and the determination of this question is necessary, owing to the conclusion we have reached upon the one which we will now proceed to discuss.
A remedial or curative statute, which merely changes the rule of evidence or the order of its introduction, and does not take away a vested right, is valid.
But although the burden of proof may be thereby changed, this does not relieve the plaintiff from alleging so much in his petition as is necessary to show a right in him.
• This rule does not violate the one that a party need not by his pleading anticipate his adversary’s defense, or allege what he is not required to prove, *12or the facts which constitute a defense to his own action. The section of the act in question does not require the defendant to aver as well as prove the defenses therein enumerated, and some of them are certainly essential affirmatively to the plaintiff to show a right or cause of action in him. Certain acts are necessary to create an enforceable tax demand. In this instance none of the preliminary steps, as listing or assessment, leading to a lawful sale, are alleged.
It is urged, however, that the law presumes official action to be correct; that this act so declares by requiring the defendant to prove the five defenses allowed to him by the 19th section, and that you need not allege what you need not prove.
The Legislature, however, cannot, under the guise of regulating the remedy, dispense with allegations by a plaintiff which are necessary to show that he has some right when he asks a court to pass upon it. It may, by statute, give him the negative of the issue as to the proof, but it can not require the defendant to both allege and show a right in the plaintiff, and dispense with the latter, stating the facts by pleading, which are essential to the existence of his right to sue, any more than it can deprive a defendant of an existing substantial defense.
Our Code of Practice requires a petition to state the facts which constitute the cause of action. The statement of a fact material to it can not be obviated by the statement of another fact which raises a prima facie presumption of its existence. The sale and conveyance by the Auditor is but a single link *13in a chain of facts, which must exist to support a tax title and an action upon it. It is urged that scarcely a single tax title under such a rule can be maintained; and that it will be almost impossible for the .State to collect its revenue. We are, however, unwilling to suppose that its officers can not at least learn to comply with the law if they are not now doing so; and it is only by the preservation of such a rule that the fundamental rights of the citizen can be maintained.
When a litigant claims rights under the act of an officer he should state the facts which show that the latter had a right to act. A tax deed results from the exercise of a statutory power; and if the necessary preliminary steps are not taken, the power is not created.
After a careful review of the older as well as the later cases in this State, we do not think that this view is in conflict with them; and certainly not with the later ones; and it is in harmony with the opinion of the Supreme Court of the United States, and with those of the courts of last resort in nearly every State in the Union.
Judgment affirmed.
