OPINION BY THE COURT
[1] The state, by J. W. Norment, special collector, brought suit upon a tax assessment of 1897, praying personal judgment, and for a declaration and foreclosure of a lien upon the property assessed. A demurrer filed was based upon Laws 1921, c-. 133, § 474, which reads as follows:
"All taxes accrued upon any property in this state prior to January 1, 1910, whether assessed or not, when no tax sale has been made therefor to a purchaser other than the county, shall be presumed to have been paid, and any tax lien therefor is hereby discharged, and it shall be the duty of all county treasurers to mark such taxes paid."
The state contended that the section just quoted was ineffectual to defeat its cause of action because of section 32, art. 4, of the Constitution, which reads as follows:
‘ ‘No obligation or liability of any person, association or corporation, held or owned by or owing to the state, or any municipal corporation therein, shall ever be exchanged, transferred, remitted, released, postponed, or in &ny way diminished by the Legislature, nor shall any such Obligation or liability be extinguished except by1 payment thereof into the proper treasury, or by proper proceeding in court.”
*316The trial court sustained the demurrer, holding that the statute, if ineffectual as a discharge of the taxes, did at least operate as a statute of limitations to bar. the remedy, and did also discharge the lien, neither of which effects, he held, is obnoxious to the Constitution. The state has appealed.
The above-quoted constitutional provision has been under consideration four times, and each time it has involved questions of taxation. In Board of Education v. McRae, 29 N. M. 85, 218 P. 346, we held that the repeal of a law under which a poll tax assessment had already been made could not effect liability lor such assessment In Asplund v. Alarid, 29 N. M. 129, 219 P. 786, we considered that a property tax once duly assessed would be, and held that a per capita road tax duly assessed was, such an obligation or liability as could not be released or amended. In Lewis v. Tipton, 29 N. M. 269, 222 P. 661, we held that the time of redemption of a tax certificate owned by the state might be extended. The theory of this dec-ision was that, when the county bids in the property, the taxpayer’s obligation or liability is extinguished, and that, when he subsequently redeems the property, he in effect merely purchases real estate from the state. State v. State Investment Co., 30 N. M. 491, 239 P. 741, does not seem to have any bearing upon this case. These decisions seem to dispose of the first of appellee’s positions; namely, that a tax assessed is not such an obligation or liability as is contemplated by the Constitution in providing that such obligations or liabilities may not be released, etc.
[2] Another of the appellee’s contentions is that there is nothing in the constitutional provision to prevent the Legislature from releasing the state’s lien upon the property. He points out that the lien is purely of statutory origin, does not exist unless expressly provided by statute, and insists that it may be discharged at the will of the Legislature. Appellant’s reply to this contention is that a tax lien is essentially an “obligation or liability held by the *317state.” In a broad sense that contention may be correct, but it does not go far enough. To come within the language of the Constitution, it must be an “obligation or liability * * * of any person, association or corporation. * * The tax lien would not seem to be an obligation or liability of a person. As a lien, it is binding only on property. That it happens, also, to be a personal obligation in this case, or, rather, that there is a personal obligation in the same amount, and of the same origin, does not alter the situation. The co-existence of a personal obligation or liability is quite unessential to a lien, 37 C. J. 310, 311. So we hold with the trial court that, in so far as the statute has discharged the lien, it is not violative of the Constitution, and is to be upheld.
[3] As to the personal liability sought to be enforced appellee contends that, if section 474 cannot be sustained as a discharge or remission of the tax, it should be upheld as a statute of limitations, not discharging the liability, but merely barring the remedy. Such has been held to be the effect of our general limitation statutes. Newhall v. Field, 13 N. M. 87, 79 P. 712, 12 Ann. Cas. 979; Joyce Pruitt Co. v. Meadows, 27 N. M. 529, 203 P. 537; Baca v. Chavez, 32 N. M. 210, 252 P. 987. We fail to discover in this statute, however, the earmarks of an ordinary statute of limitations. A statute which merely bars the remedy is one of repose. It forbids the preferring of stale claims as matter of public policy. But this statute is one of presumption of payment, and directs the county treasurers to make record of actual payment. It does not act prospectively as statutes of limitations do. It acts only retrospectively. It allows no time within which the state may proceed on these old taxes before the bar is to fall, as statutes of limitations must do which are to affect private contract obligations. The plain purpose and necessary effect of this section is to remit and release tax obligations. If the Legislature may remit and release them when 11 years old,' it may do so when they are but 3 years old. So we doubt the correctness of classifying sec*318tion 474 as a limitation statute. But the name or classification of the statute does not matter. It is the effect that condemns it. Admitting that it has done nothing more than to bar the remedy, leaving the obligation or liability intact, to be enforced if perchance a future Legislature should repeal section 474, yet the effect has been at least to “postpone” the obligation or liability — a result equally obnoxious to the Constitution. "We do not consider, as we need not, whether an ordinary statute of limitations would be objectionable. We hold only that section 474, in its purpose and effect, is void, in so far as it attempts to prevent recovery by the state of personal judgments for taxes previously assessed, and therefore possessing the quality of obligations or liabilities of a person, association, or corporation held or owned by the state. .
[4] Appellee also challenges the authority of the special collector to maintain this suit. Such authority is derived from chapter 26, Laws of 1925, and is limited to the collection of “delinquent taxes.” Section 1 of that act defines delinquent taxes as “unpaid taxes * * * which were levied or assessed prior to the year 1924 and not barred by statute. * * *” It is argued that it appears from this that the Legislature intended to give the special collector no authority to collect taxes assessed prior to 1910. We agree with the trial court that there is no merit in this argument. The 1925 Legislature may have considered that the 1897 taxes were barred by the statute, but we have found that they are not. We can see no reason to hold that the Legislature, in defining delinquent taxes as it did, intended to restrict the authority of the special collector as to any taxes which might, as a matter of law, be delinquent. The wise purpose of so defining them was, we think, to avoid a definition in conflict with section 474. Had the Legislature intended to limit the authority of the special collector as to the taxes assessed in any particular years, it could easily have made such purpose clear.
*319The complaint, therefore, states a cause of action which will support a personal judgment against the defendant. The judgment must be reversed, and the canse remanded, with direction to the district court to overrule the demurrer and to proceed in the cause consistently herewith.
It is so ordered.
