It was held by this court in The Dunleith & Dubuque Bridge Co. v. The City of Dubuque. 32 Iowa, 427, that the property of railroads within the city of Dubuque is liable to municipal taxation the same as other property. The decision in that case was rendered in October, 1871. Subsequently to the assessment and levy of the tax for which the action before us was brought, and after the tax became due and collectible, an act of the legislature was passed containing the following provision:
“ Every railroad company which shall have paid all taxes on the gross earnings provided for by Chap. 105 of the Acts of the 13th General Assembly, shall be released from the payment of all other taxes which may have been levied upon the *60road-bed, right of way, track, rolling stock and necessary buildings for operating their road, and no taxes for prior years, for State, county, municipal, or any other purpose, for which any tax can be levied under the laws of the State, up to the first of January last, shall be collected from any such railroad company on such property.” Laws 1872, Chapter 26, § 9.
Two questions are presented for our decision which arise upon the facts of the case: 1. Is the liability and obligation of defendant for the payment of the tax discharged by the enactment just quoted? 2. ’ Is the rolling stock of defendant used in the State liable to municipal taxation in the city of Dubuque?
- I. The first question, which we now proceed to consider, involves the constitutionality of the statute, by -the force of which, it is claimed, the taxes sued for a\’e discharged, and are therefore not collectible.
No question is made as to the legality of the assessment and levy of the taxes in question. The lawful power and right of the city to impose them upon the property of defendant was determined in The Dunleith & Dubuque Bridge Co. v. The City of Dubuque, supra. The sole question, then, to be determined in this branch of the case is this: Can the legislature discharge the obligation of defendant to pay the tax, as it is attempted to be done by the law in question?
i. taxation; naturooi a tax. It is first necessary to inquire into the nature of the taxes for which suit is brought. They were levied under .the authority of law, and are not different in charac- •' , ; . . . ter, as to the obligation resting upon the tax payer to discharge them, from any other legal assessments. As in the case of other taxes, there is a duty resting upon the defendant to pay them, and there is a correlative right of the city to receive and collect them. The law creates this duty and this right. We have here the case of an obligation whereby the defendant is bound to pay the money in suit; the obligation is raised by the law which implies an undertaking of defendant to pay the taxes. The case fills the. definition of a contract, a term which, in its more extensive sense, includes *61every agreement, obligation, or legal tie, whereby one party becomes bound, expressly or impliedly, to another to pay a sum of money, or to do or omit to do a certain act. Bouvier’s Diet., Tit. Contract; Chitty’s Contracts, p. 2; 3 Blaclrstone’s Com., 158.
By the lawful levy of the taxes in suit, which were assessed against the defendant, and not in rem, defendant became personally bound for their payment. This obligation created a debt in the sense of the term when applied to a liability for the payment of money. This doctrine and the principles upon which it is founded, are supported by the following authorities: Dugan v. The Mayor, 1 Gill. & Johns., 499; The Mayor v. Howard, 6 Har. & Johns., 333; Gordon's Ex'rs v. Mayor of Baltimore, 5 Gill., 231; Ryan v. Gallatin County, 14 Ill., 78; Dunlap v. Callatin County, 15 Ill., 7; Mayor etc. of Jonesboro v. McKee, 2 Yerg., 167; City of Oakland v. Whipple, 39 Cal., 112; The State v. Poulterer, 16 Cal., 514; People v. Seymour, 16 Cal., 332; Portland Dry Dock & Ins. Co. v. Trustees of Portland, 12 B. Monr., 77.
2. constitutaxatfon^raui roads. The right of plaintiff to the taxes in question and the obligation of defendant to pay them were perfect before the statute under consideration was enacted. Plaintiff had a valid, legal claim against defendant for the amount of the assessment. This claim — a chose in action — was property, and entitled to the same protection from the law as other property. It rested, as we have seen, upon a contract implied by the law, whereby defendant was bound to pay the money in suit to plaintiff. The statute in question deprives plaintiff of this property by declaring the taxes levied by the city shall not be collected, and by releasing defendant from their payment. It impairs the obligation of the contract implied by the law whereby defendant became bound to pay the taxes, by attempting to relieve defendant therefrom and declaring plaintiff shall not enforce its lawful claim therefor. Here, by a statute, is an attempt to deprive plaintiff of its property without due process of law, and to utterly impair the obligations of a valid contract. The legistature is expressly prohibited by the constitution from *62the exercise of” such despotic and oppressive power. Constitution, Art. 1, §§ 9, 21. ■ ■
The view just expressed is based upon the fact that property held by a municipal corporation, and contracts made with them, are entitled to the same protection of law as those wherein natural persons are alone concerned. The right of a city to' hold property, and the binding nature of obligations entered into with it, cannot be doubted. Its rights in these respects are protected by the constitutional guarantees above cited. This doctrine is nowhere denied.
Counsel for defendant, in opposition to these views, assert that a tax is a mere burden or duty, and is not a debt. In support of this position they cite the following cases: The City of Camden v. Allen et al., 2 Dutch, 398; Perry v. Washburn, 20 Cal., 318; Pierce v. The City of Boston, 3, Met., 520; Lane County v. Oregon, 7 Wal., 71; Shaw v. Picket et al., 26 Vt., 482; The People v. Craycroft, 2 Cal., 243; Kidder v. Boom Co., 24 Pa. St., 193.
It is admitted that the four cases first named hold that liabilities for taxes are not to be regarded as debts in the ordinary sense of the word so far as to authorize actions to be brought for the recovery thereof, or to require them to be considered the proper subjects of set-off, or to bring those levied by state authority within the terms of the statute of the United States, making treasury notes legal tender for debts. Upon a careful examination of the other cases mentioned above, we do not find that they possess the force claimed for them. The opinion in Shaw v. Picket contains expressions used arguendo, which give some color to the claim of counsel that it supports their position. The rulings upon the points involved in the case, however, do not have that effect. The same remark may be made with more confidence in regard to the other cases.
It may be admitted that the obligation for the payment of taxes will not support an action, when the law. provides another remedy, and that taxes are not the subjects of set-off, nor within the purview of the legal tender act; yet it by no means follows that a tax is not a debt in the true sense of the *63term, and protected by law as all other property of that character. These matters do not grow out of or inhere in the nature of the obligation, but pertain to the remedy thereon; they do not affect the right of property existing therein, but simply relate to the remedy by which that right may be enforced. It cannot, therefore, be claimed that because of them the right to enforce the collection of taxes is not property.
The language of the cases under consideration used upon this point is indefinite and wanting in accuracy. It is said that liabilities for taxes are not debts “ in the ordinary sense of the word,” or “ within the common understanding of the word.” The word debt is defined by Webster to be “that which is due from one to another, whether of money, goods or services; that which one person is bound to pay or perform to another.” Certainly this is the “ ordinary sense, the common understanding” of the word, which may be accurately applied to liabilities for taxes. The doctrine of the cases under consideration, so far as it tends to deny that the same rights of property attach to liabilities for taxes as to debts generally, is in 'conflict with principle and authority.
municipal corpoiation. II. It is argued by defendant’s counsel that, as the city of Dubuque is a "municipal corporation organized for political purposes, its corporate powers may be abridged or entirely taken away,' being in no sense vested as against the State. It is therefore insisted that the city may be lawfully deprived of the right To collect taxes legally levied. Without contesting the correctness of counsel’s premises, it is very plainly to be seen that their conclusion is a non sequitur. It must be remembered that a municipal corporation, though a public and p olitical institution, deriving its life and powers from the State, possesses a private and proprietary character and, as such, may acquire and hold property and make contracts. It is protected in its property by the same constitutional guarantees that extend over natural persons, and the restriction upon legislative action impairing the obligation of contracts preserves those made with it. Eights held by it in its last named character are beyond legislative control and interference.

2. A position of Messrs. Withrow, Edmonds and Ransom, counsel for other railroad companies interested in the questions involved in this discussion, demands particular notice because of the able and ingenious manner of its presentation, and the specious character it is made to assume. It is best and most fairly presented by using their own language, which is as follows : “ We shall endeavor to show, both upon principle and authority, that the right to levy and collect taxes is a public and not a private right, and that it can in no sense, and in no case, become a private vested right. The principle upon which rests the distinction between public and private rights may be stated as follows : Rights which may be conferred upon, and exercised by a private person or corporation, may be private when held and exercised by a municipal corporation / while rights exercised by a mionicipal corporation, but which can never be exercised by a private person or corporation, are necessarily public T
The law as a science is distinguished for its accurate use of words and terms. When this characteristic of the science is lost or disregarded, in legal discussions, confusion follows and erroneous conclusions are likely to be-reached. The ingenious substitution of one term for another, or the use of a word out of its true place,' often gives a speciousness to an argument that bewilders and is difficult to expose. And this is the fault of the language above quoted, which we will endeavor briefly to point out.
In the first place rights are not classified or distinguished as public and private. No authority makes any such classification. Wrongs are distinguished as public or private and the relations of persons may be either public ox private. The legal mind at once grasps the ideas intended to be conveyed by the use of these terms, but it fails to comprehend the *65expressions, public rights and private rights. Rights held by public, political corporations, as to every element inhering therein, which is necessary to create a right, differ in no respect from rights secured by the law to private persons. They differ as to the subjects upon which they operate, and those of the first are more limited in number than those of the second. But it is a misuse of terms to distinguish rights as public and private, thereby implying that the one class differs from the others as to the security guaranteed by the law thereto, or the remedies provided for their deprivation. The right of property is as sacred when held by a public corporation as when secured to a private person. - It is true these corporate rights may be subject to control that cannot be exercise! over the rights of an individual, but in no case can they be taken away or impaired by any power in the State.
The word rights occurring in the passage quoted above is improperly used in place of the term powers. By substituting the last named word for the first, the doctrine announced would probably be unobjectionable and find support in the authorities. A public corporation is clothed with the power to levy taxes; such authority cannot be conferred upon a private person. The power may be said to be public. So the corporation may be authorized to acquire property; a private citizen possesses the same power, which, when it is exercised by a public corporation, is properly called a private power. This, and nothing more, is clearly the import of the authorities cited by counsel. See Bailey v. The Mayor of New York, 3 Hill, 531; The San Francisco Gas Company v. The City of San Francisco, 9 Cal., 468; Dillon on Municipal Cor., § 39, note.
The powers of a public corporation are conferred by the legislature, and may be taken away by the same authority.
In the exercise of these powers, while lawfully possessed, the corporation acquires property. Here, then, is a right brought into existence — a right of property. The right originated in the exercise of lawful power. The power may be taken away, but the right, its offspring, continues to exist. Future rights cannot be acquired under the power, for it can *66no more be exercised. Existing rights are not affected, by this abrogation of the power.
In the case before us, the city was clothed with power to levy the taxes in suit, and lawfully exercised that authority. The railroad company became bound to the city for the payment of the taxes. This liability, this debt, as we have seen, is property, and beyond legislative interference. The power under which the levy was made may be taken away by the legislature and other taxes may not again be levied thereunder, but the property right in the liability for the taxes already levied remains unimpaired.
3. The property of public corporations may be under the control of the legislature, so far as to direct the uses to which it shall be devoted. The corporation exists for governmental purposes, and the property is acquired to enable it to discharge its functions. • It is within the power of the legislature to direct the exorcise of corporate powers; to designate the objects for which and upon which such powers may be exercised; to authorize the expenditure of money therefor, and the like. Doubtless in the exercise of this constitutional authority, the legislature may control the expenditure of money by a city. But it must not be forgotten that a restriction is placed upon the exercise of this legislative power, namely: the corporate property can only be used for the public purposes for which the city exists. It cannot be exercised to destroy the property or divert it from public to private use. In the case before us, the property of the city, in the taxes, is destroyed for the benefit of the railroad company. The practical effect of •the legislation in question is to take money from the city treasury, which by law, is intended for public purposes, and pay it without any consideration received therefor by the city or the State, to the railroad company.
4. It is insisted that the statute in question simply provides for a commutation of taxes which is within legislative authority. We find it unnecessary to enter into an inquiry as to the exercise of this power, or the extent to which it may be carried. In our opinion the statute does not provide for commutation, but is intended absolutely to release the taxes in suit. To *67commute is to exchange; to put one thing in the place of another; to give or receive one thing for another. There can be no commutation unless, for the thing taken, something shall be returned. The statute takes from the city taxes in which it has acquired property, and gives nothing in return. Eut it is said it authorizes a levy of other taxes in lieu of those released. But these are not taxes to be paid to the city, nor are they for the years for which the released taxes were levied. In lien of the taxes due the city, not one cent under the law is paid into the State or city treasury. The law simply releases valid taxes without the pretense of any consideration in return. The point, to our minds, demands no further consideration.
III. It is next argued by counsel that the statute in question does not impair the obligation of a contract because the laws which establish municipal corporations are not contracts, and may be repealed and changed at the will of the legislature. The principle of law here stated may be admitted, but it is inapplicable to the case before us. The contract impaired by the statute in question is not a contract between the State and the city, embodied in the laws creating and conferring power upon the latter, but the obligation resting upon defendants to pay the taxes in suit. The case is this: The plaintiff is created by the State, and endowed with power to levy taxes. It becomes, by this legislation, an artificial person, capable of making contracts within the scope of its corporate powers, and enforcing its rights thereunder. In the lawful exercise of its powers it levies the taxes in suit. The law raises an implied contract, binding defendant to pay these taxes. This is the contract which is impaired.
It is true that the legislature may take away the powers conferred upon the city — may destroy its corporate existence, but cannot divest it of property or rights under contracts lawfully acquired. The State, by legislation, may decree the death of the municipality, and may become its executioner, but cannot seize and dispose of its estate at will. The authority of the legislature to take away or abridge municipal powers, by no means carries with it authority to destroy *68rights of property, and rights under contracts, acquired while those powers were lawfully possessed and 'exercised.
4 _._. ’--• IV. The property of the railroad company, we have seen, was subject to taxation by the city and was not within the class of non-taxable or exempt property. The levy of the tax released was lawful. The effect of the legislation under consideration is. to relieve a part of the taxable property of the city from a burden lawfully imposed thereon. The property of plaintiff, if the law be valid, is not subject to taxation the same as that of other property-holders of the State. The plaintiff is discharged from taxes upon its taxable property, while residents and tax-payers of the city are liable for the assessment upon their property. It is very evident that plaintiff’s property is not taxed the same as that of others. The statute, in producing this result, is in plain contravention of the State Constitution. Art. 8, § 2, is in these words: “ The property of all corporations'for pecuniary profit, shall be subject to taxation, the same as that of individuals.” The language of this provision is so simple and direct that it cannot be made plaiper by exposition. Its obvious meaning is that the property of artificial persons, existing for pecuniary profit, shall be assessed, and taxes thereon levied and collected, for these acts are incidents in rendering property subject to taxation, the same as that of individuals. The same rule of taxation that extends to individuals, citizens, residents, who are tax payers of the State, must be applied to corporations of the character contemplated. While the explicit language of the provision leaves no room for doubt as to its meaning, the reasons upon which it is based give double assurance of the correctness of our interpretation. It is essential to the justice of taxation that it be uniform, bearing equally upon owners of all property which is uuder the protection of the laws of the State. All not exempt must pay taxes, which are not to be imposed alone or unequally upon particular individuals or classes. Warren v. Henly, 31 Iowa, 31. If classes or individuals be exempted from taxation, uniformity and equality is destroyed. This uniformity in taxation is within the purview of Art. 1, § 6, of the Constitution, *69which secures uniform operation of all laws and forbids the General Assembly to grant to any citizen or class of citizens special privileges or immunities. The history of corporations for pecuniary, profit in this country shows that there long has been a disposition on the part of these artificial persons to seek, and on the part of legislatures to grant, immunities and exemptions from taxation. It has often occurred that their charters provided for total exemption from taxes or for rules of taxation applicable to them, different from those affecting other property holders. Legislation in other forms has been often sought and granted, securing the same end. The law before us, as well as others enacted in this State, bear evidence of the correctness of this statement. Against such legislation, the evils of which existed and were felt when the Constitution of 1857 was adopted, the provision above quoted was aimed. [See Code 1851, § 462.] The end sought and attained thereby is the equal and uniform taxation of the property of all the tax-payers of the State.
The language of the provision must be understood to be mandatory, and not permissive. If it be regarded as permissive .only, the provision is nullified. Undoubtedly, without it the legislature could provide for the taxation of the property of corporations the same as that of individuals and justice would so demand. There is no restriction upon the legislative power forbidding uniform taxation or perventing its application to corporations. If, therefore, the language of the section be construed as pennissive, it grants no power and imposes no restriction upon the exercise of power, and is rendered meaningless.
The provision is not limited in effect to any particular class or kind of taxes, considered either as to the property upon which they are levied, or the purposes of their imposition, or the branch of the civil government for the support of which they are collected. The language is general and comprehensive. The word taxation applies to all assessments for public purposes which are called taxes, .and are authorized by law. Municipal taxes are within the language and spirit of the constitutional provision. They are levied for public purposes, *70and are authorized by law. The State delegates to the cities its police and civil authority, which is exercised for the protection of property and persons therein. To enable these corporations to exercise the authority thus conferred, the power of taxation is necessary, and for that purpose is g’ranted. Taxation for such purposes is obviously within the purview of the constitutional provision under consideration. Weeks v. The City of Milwaukee, 10 Wis., 242; The City of Zanesville v. Richards, Auditor, etc., 5 Ohio St., 589.
The conclusion just announced is supported by considerations of justice, which should always have controlling weight in construing laws, both constitutional and statutory, admitting of conflicting interpretations, in order to arrive at the true intentions of the law-makers, which, in such cases, must be presumed to accord with right. Under the statute involved in this-case and the doctrines njjon which it is attempted to be supported, the legislature exempts railroad property from municipal taxation, — relieving it by special enactment from taxes lawfully levied. The cities are charged with the duty of giving protection to the property and business of the railroad corporations found and transacted within their limits. In many of them, such property, both real and personal, of vast value, is situated. In some instances many acres of ground, almost in the heart of the cities, are covered with railroad cars and buildings, subject to conflagrations and other causes of destruction and loss. The business houses and dwellings of the people are endangered by proximity to such vast collections of combustible material. The city is charged with the protection of this property from destruction, and expensive machinery must be maintained for that purpose. The personal property of the railroad companies, as well as that carried by them, must be protected from pillage and larceny, and good order must be preserved in the throngs of people that are constantly found about their depots, entailing large outlays for the support of the police force of the cities. These expenses and resj)onsibilities are imposed upon the municipalities for the protection of the property and the rights of the corporations. Taxes levied by the cities upon railroad property, to be *71disbursed for these very purposes — the protection of the property itself, are remitted and discharged, and the people are left to bear the whole burden, by the statute under consideration. The result is grossly unjust, and is brought about because the property of railroad corporations is not taxed as that of individuals. It is to be presumed that the framers of the constitution intended by the provision above quoted, to protect the people from the evils and oppression of such legislation.
We have not, in the preceding discussion, intended to convey the thought that taxes upon all property must be levied in the same manner, but that all property must be subjected to taxation for the same purpose. This remark will prevent a misunderstanding of the real point ruled.
5, action: tclX3>tÍ01I practice.' V. It is argued that when a statute prescribes the method for the collection of taxes, it is exclusive. By law the taxes in question are collectible by distress and sale of personal property, and by the sale of real property upon v ' d AAt/A which they may be levied. It is therefore claimed that an action at law cannot be maintained to recover them. No sueh objection was raised by the pleadings, or appears to have been urged in any manner in the District Court. Ooun'sel for plaintiff may possibly be understood to make the point in this court. If they so intend it is done with great brevity and indistinctness. All that is said by them is found in one short paragraph, which is in the following words: “ Without statute conferring the power, the city could not collect a tax, either by suit or otherwise.” This proposition counsel support by the citation of the following language found in McInerny v. Reed, 23 Iowa, 415: “There is an inherent or common law power to enforce a debt proper, as for money lent or services rendered. But there is no such power to enforce the collection of a tax or assessment; there must be a statute.” Not another word is found in their brief upon the point.
But counsel for other railroad corporations, having cases pending in the courts which involve the validity'of taxes levied by other cities, in printed arguments submitted for our consideration, have , presented and elaborately argued the proposition.
*721. As this question was not made in the court below, and involves a defense that ought, in some form, to have been made there, we cannot consider it. The rule that questions not raised in the court below will not be considered here, is too familiar to demand in its support the citation of our former decisions announcing it.
2. It is not a question which involves the jurisdiction of this court, or of the District Court. Were it of that character it could be interposed in either court at any stage of the case. The District Court has original jurisdiction to entertain all actions for the enforcement of rights, the deprivation of which has its remedy in that way. The ordinary remedy to enforce the payment of money, which a party is under obligation to pay, is by action. The general proposition is true that if one party is indebted to, or in any manner bound to pay, another a sum of money, the latter may maintain an action against the former to recover it. The law may provide a special remedy in certain cases, which the plaintiff is required to pursue to the exclusion of all others; in these an action would not lie. But should an action be brought in such a ease and, without objection to the proceeding, be prosecuted to judgment, upon appeal to this court, the objection cannot1 be first heard here. The reason of the rule is this: The jurisdiction of the court is not taken away, but the party is required to seek under the circumstances, relief elsewhere. The circumstances or facts which require him to pursue the special remedy must be pleaded, or in a proper manner shown to the court entertaining the action, in order to defeat it.
Now the counsel urging the objection under consideration, admit that an action at law may be maintained to recover taxes lawfully levied when the manner of their collection is not otherwise provided for; that is, if there be no special proceedings prescribed by law, an action will lie. . They cite many authorities to support this proposition.*
*733. The proposition admits the jurisdiction of the court, but denies that it may be exercised under the circumstances of the case, viz: when another remedy is provided. Now it is plain that, to defeat an action of this kind, the fact that another remedy is prescribed by law must be pleaded thereto or in some proper way brought to the attention of the court as a defense; otherwise the judgment will be valid. This defense to the action, for such it is, cannot be first made here. This court has held that, under a statute requiring the assent of the county court to the prosecution of an action against an administrator in the district, the want of such assent cannot be first urged upon appeal as an objection to the judgment rendered in such an action. Elder v. Littler, adm’r, 15 Iowa, 65. The principles upon which that decision is planted support the views we have just expressed.
Our conclusion is that the objection under consideration, even were it well taken, or had it been made in the District Court, cannot avail him.
4. However, as the objection is elaborately discussed by counsel who are concerned in other cases wherein it is said to arrise, we may with propriety express our views upon the questions involved therein, which we will proceed, briefly, to do.
The ordinary remedy to enforce a liability for the payment of money, is by action. If a debt exist, if one is bound expressly or impliedly by agreement, obligation or legal tie, to pay another a sum of money, an action at law may be maintained thereon. In every case where the obligation is recognized by the law, the remedy is given. This remedy may be taken away and another given by statute. But the mere fact that a new and additional remedy is given will not destroy the common law right of action; either remedy may be pursued by the party seeking the enforcement of his rights. The intention of the legislature to take away the right of action must appear with sufficient certainty, and not by implication from the mere fact that another remedy is provided. We think these general doctrines cannot be denied, and are so familiar that the citation of authorities in their support will not be expected.
*74A former Chief Justice of this court, in his valuable work upon. Municipal Corporations, applying these very doctrines to the question of the right to maintain an action for the collection of taxes, uses the following language : “ When the power to levy the tax is plainly given, the right, to collect .fry suit should not be taken to be impliedly denied, unless the intention of the legislature, that the special mode prescribed should be the only mode, appears with reasonable certainty. If the special remedy is full and adequate, such an intention on the part of the law-maker would be more readily deduced than it would under other circumstances.” Dillon on Municipal Corporations, § 653. This quotation is made with more confidence in answer to the positions of counsel because they themselves cite the identical language in their'support. It is explicit and forcible, and demands no comment. In the legislation authorizing the levy of the tax in question, nothing can be found authorizing the inference of a legislative intention to take away the remedy by action. Further discussion of principle involved in the question seems unnecessary. It is, in our judgment, supported by the great weight of authority. The following cases, it is believed, fully recognize the rule that actions at law may be maintained to recover taxes though special remedies be provided by statute therefor.
Mayor v. Howard, 6 Har. & Johns., 383; Dugan v. Mayor, 1 Gill & Johns., 499; Clemens v. Mayor, 16 Md., 208; Ryan v. Gallatin Co., 14 Ill., 83; Dunlap v. Gallatin Co., 15 Ill., 7; City of Oakland v. Whipple, 39 Cal., 112; Mayor v. McKee, 2 Yerg. 187; The People v. Seymour, 16 Cal., 334; The State v. Poulterer, 16 Cal., 514; Portland Dry Dock and Ins. Co. v. Trustees of Portland, 12 B. Monroe 77; The Dollar Savings Bank v. The U. S., 19 Wal., 277.
5. Of the numerous cases cited by counsel representing the railroad corporations, not parties to this suit, we esteem The City of Camden v. Allen, 2 Dutch, 398, and some of the Massachusetts cases, to be in point. The others hold that taxes do not bear interest unless it is so prescribed by statute, are not the subject of set off, cannot be taken on execution, and cannot be attached by garnishment-; that a tax collector can*75not sue in his own name to recover taxes without authority of statute; that a suit in equity will not lie to recover for taxes and the like.*
YI. The very case under consideration illustrates the wisdom of the rule we adopt, and its necessity, to the end that speedy and exact justice be done. The collection of the taxes involved therein is resisted by the railroad company, on the ground that they have been discharged by an act of the legislature. This law is claimed by the city to be void, because it is in conflict with the constitution. Plere is a grave constitutional question, upon which the very merits of the case depend. If the law be unconstitutional, the taxes are collectible; if valid, they are discharged. Certainly the most zealous of the counsel for the railroad company cannot deny that this grave question is not free from doubt. But, according to their views, it can only be brought before the courts in the State in actions growing out of attempts of the tax collectors to enforce payment of the taxes by distress( and sale of personal property or by sale of real estate upon which the taxes are levied. If the statute in question be held constitutional, the collectors in such cases would be trespassers, and liable as such. If it be held invalid, the distress and sale by the collectors would be sustained, and titles originating thereunder would be upheld; thus, as it will be clearly seen, exposing the railroad company to great loss. In either case hardships and absolute injustice would result. But, by determining this grave constitutional question in an action to recover the taxes, these consequences are avoided. The rights of the parties are *76settled without interfering with the property of the railroad company, without exposing officers of the law to vexatious and harrassing suits for damages, and without hazard of the loss of personal or real property by tax sales. Certainly, the true interest of both parties and sound public policy demand that the right of action be sustained by this court. These considerations, it must be presumed, were contemplated by the legislature, and were sufficient reasons, in the exercise of its wisdom, for the preservation of the right of action for the recovery of taxes, while granting a special and more summary remedy. They are sufficient grounds to authorize the presumption, in the absence of an express declaration, of a legislative intention to that effect.
We will not be understood to hold that, in ordinary cases, where no special circumstances exist, taxes may be collected by action. But simply that where the rights of the State, or of the sub-divisions of the State, levying taxes, or the rights and interests of the tax' payers, may be better enforced and protected through an action at law to recover taxes, in such a case that remedy may be presumed.
YII. We come to the consideration of the second branch of this case, which involves the liability of defendant for the taxes levied upon the rolling stock. A preliminary statement of a few facts not before mentioned is necessary. The defendant is a corporation, existing under the laws of the State of Illinois, and, during the year 1871, the period for which the taxes in suit were assessed, was operating a line of railroad from Dubuque to Sioux City, with its headquarters for the prosecution of this .business in the first named city. The engines and cars of defendant, denominated rolling stock, were used by the defendant in operating its line of railroad between the two cities above mentioned, and were duly assessed at the value of $300,000.
c. taxation: rolling stock, It is claimed that the rolling stock is not liable to taxation, under the decision of this court in The City of Davenport v. The M. & M. R. Co., 16 Iowa, 349. It was held in that case, that the city of Davenport, having power and authority under its charter “ to levy and collect *77taxes upon all taxable property, real, personal, and mixed, within the city,” could not tax a railroad company that kept its principal business office therein and operated a railroad running from within its borders to another point in the State, upon the rolling stock used in operating such railroad. The facts of the case do not differ materially from those of the action before us. The property called rolling stock in each instance, was used all along the lines of the respective roads as business required, the engines and cars passing over the whole length of the roads in the manner that is customary in operating roads of like character.
All of the Justices, in the case referred to, united in holding that the rolling stock of the railroad was not taxable by the city of Davenport, but they assigned different reasons in support of this conclusion. One of the Justices, (Lowe), thought that the rolling stock is a part of the road itself, and not taxable separately therefrom, but was of the further opinion, in which Oole, J., concurred, that the city was not clothed with power to tax the property, either real or personal, of railroads. Wright, Oii. J., and Dillon, J., held that the city could impose taxes upon the property of the railroad situated within its limits, but were of the opinion that the rolling stock was not taxable on the ground, as we understand their opinion, that it ■was not within the jurisdiction of the city for the purpose of taxation. They concede that it is taxable property, but was not “ within the city,” so that it was liable to city taxation.
Under the ruling of this court in Dunleith & Dubuque Bridge Co. v. The City of Dubuque, the property in question is taxable and subject to municipal taxation, if within the jurisdiction of the city for that purpose. We do not understand that Wright, Oii. J., and Dillon, J., in the case just referred to, express views as to the power of the city to tax the property in conflict with our later decision, but, on the contrary, in full accord with it. But, as a question of law, they held that the property was not taxable by the city, because, in contemplation of law, it was not within its limits. They concurred with the other members of the court in holding the property exempt from taxation on the ground that its situs *78was not witliin the city. The points of law then determined by them, and which controlled their decision, related to the situs of the property. They hold the rolling stock to he personal property, and not a part of the road itself. Lowe, J"., holds that the rolling stock is a part of the road, and for this reason, as we understand his opinion, can have no such situs in the city of Davenport as to entitle said city, “ more than any other town or city through which it passes, to tax the same for municipal purposes.” He further states the position and reasons of the District Court leading to its decision, (Dillon, J., then occupying that bench,) which are substantially the same as announced in-the ojnnion of the other Justices given in the case. But we do not understand they rest upon the ground on which he bases his conclusion. Oole, J., while concurring in the conclusion of Lowe, J., does not reach it by the same course of reasoning, nor by the application of the same legal principles. He expresses no opinion upon the questions discussed by the other Justices as to the situs of the rolling stock, and as to its being a part of the road itself. Upon these questions of law he gives no opinion. ITe reaches the conclusion that power to tax the property of the railroad was not conferred by the legislature upon the city, and he concurs in no other point made by Justice'Lowe, or the other judges.
We have, then, the same conclusion reached by all the judges, while differing as to the reason and grounds upon wdiich it is based.
Two Justices hold the property to be taxable, two deny it. Two unite in holding, as a matter of law, that the property being transitory in its use, its situs was not in the city; another holds that its situs is not there because it is a part of the road itself; the other expresses no opinion, on these questions, but bases his conclusion on the absence of legislative authority to levy the tax. Now the question of law which controlled the decision of Wrxgx-it, Oi-i. J., and Dillon, J., ivas the doctrine advanced by them in regard to the situs of the property. Lowe, J., does not adopt their view as to this doctrine, but advances another whereby he announces still a different rule of law, namely, that the rolling stock, in contem*79plation of law, is a part of tlie road. That Lowe, J., did not concur in the doctrine of the other Justices as to the situs of the property, is made' very plain from the fact that he holds it to be a part of the road; if so, its situs would be that of the road, namely, in every town, township, and county through which it runs. After making this announcement he could hardly be expected, in the next paragraph, to say that it is not a part of the road; that it is personal property, and that its situs was not in Davenport, because it was used along the line of the road.
Now, we repeat that' the doctrine of the situs of the personal property announced by two members of the court,'the rule that the property was a part of the road maintained by another, and the further rule announced by the same Justice, and assented to by the fourth, all pointing toward the same result, concurred in producing the decision that the rolling stock was not taxable. But of these different principles of law, two Justices at most concur in assenting to any one of them. _ None of the opinions considered alone has the force of a decision of the court, because no one of them is concurred in by a majority of the Justices; taken collectively, they cannot be regarded as binding upon us in the character of a precedent.
Let ris inquire what is meant by the term, precedent, and what elements in a case is to be. followed under the rule stare decisis. It is not the judgment which the court pronounces upon the. rights of the parties involved in the suit. A judgment that A. recover of B. $1,000 is not to be cited as a precedent in a subsequent case to support the right of C. to recover the same sum from D., for the judgment is simply a conclusion reached by the application of rules of law to certain facts. We are to look farther in a case than to the judgment to find that which constitutes a precedent. It is found in the rules of law, which are the foundation of a judgment. These rules constitute the formula by which rights of parties are to be determined. When settled by adjudication, courts, under the doctrine stcwe decisis, are required to apply them-to subsequent cases. Upon the authority of the decision *80announcing them they are to be taken as correct. When we look to a case which is called a precedent, we search out these rules for application to the facts in dispute before us; the judgment therein constitutes a rule in no sense — it is evidence of the application of rules, legal formulae, to facts; it is the formal recognition of such rules. A case is to be regarded as a precedent when it furnishes rules that may be applied in settling the rights of parties. These rules are to be discovered in the opinions of the judges, and constitute the reasons for the decision. Lord Mansfield says: “ The reason and spirit of cases make law; not the letter of particular j>recedents.” Fisher v. Prince, 3 Burrows, 1364. And Lord Holt declares that “the reason of a resolution ('judgment) is more to be considered than the resolution itself.” Cage v. Action, 12 Mod., 294.
It has always been held that a decision of a court, concurred in by less than a majority of the judges, has not the force of a precedent. When there is an equal division of opinion in this court, the decision of the court below stands affirmed. There must be a concurrence of a majority of the judges -upon the principles, rules of law, announced in the case, before they can be considered settled by a decision. If the court be equally divided or less than a majority concur in a rule, no one will claim that it has the force of the authority of the court.
7. bbs ad.tucedent.' pre7. bbs ad.tucedent.' pre It is of frequent occurrence in this court that two j ndges, adopting rules that are not recognized by the others, reach thereby conelusions approved by all. Who would claim that such rules are to be regarded as law announced by this court? Certainly it cannot be claimed, if a decision be reached by the adoption of diverse rules by the different members of the court, that it is to be regarded as authority. We have seen that the rules of law followed in a decision constitute what we call a precedent. If the judges do not agree upon these rules, and less than a majority concur in them, the decision is not authority. Many cases are found where this rule is applied. Thus, in Woodruff v. Parham, 8 Wal., 123, the United States Supreme Court refused to follow another *81decision of the same court, License Cases, 5 Iiow., 504, remarking that “ The separate and diverse opinions delivered' by the judges on that occasion, leave it very doubtful if any material proposition was decided, though the precise point we have here argued was before the court and seemed to require solution.” So the case of Forrest v. Kissam, 7 Hill, 463, was declared in the subsequent case of People v. Cole, 43 N. Y., 508, to be of no authority for the reason that the grounds of the different opinions do not accord, and it is therefore impossible to determine upon what principles the decision is planted. In Mansfield v. Doolin, 4 C. L., 17, (Irish Eeports) a case was not followed as authority because “ the judgments of the several members of the court proceeded on different grounds.” But a multiplication of authorities is quite unnecessary to sustain a proposition so clearly established by reason and principle.
Now what principle, what rule of law, what legal formula, which may be applied to the rights of 'the parties in the case before ns, was settled in The City of Davenport v. The M. & M. P. Co.? A. We reply, not one. At the risk of repetition, we will state succinctly the principles or rules of law announced in the different opinions:
1. Weight, Ch. J., and Dillon, J., hold that the situs of the rolling stock is not in the city. They, therefore, hold the city cannot levy taxes upon that property. They do not agree with Lowe and Cole, JJ., in the rules they announce.
2. Lowe, J., holds that the rolling stock is a part of the road, and that as there is no law authorizing the levy of taxes thereon, it is not taxable property. He does not agree with Weight, Cii. J., and Dillon, J"., in the rule announced by them.
3. Cole, J., concurs with Lowe, J., that the property is not taxable on the ground that there is no enactment to that effect. He makes no other point and announces concurrence with no other view taken by the other judges.
Now but two judges agree upon any one rule announced. That the property is taxable by the city this court has decided in Dunleith & Dubuque Bridge Co. v. The City of Dubuque, *82supra. That question is out of the way. The other rules found in the different opinions are those announced by Wright, Oii. J., and Dillon, J., as to the si'.us of the property and the other one advanced by Low®, J., that the rolling stock is a part of the road. Two judges agree to the first; one to the last. In neither case can the rule be considered as supported by the authority of the court. We are not prepared to sanction either of them upon principle.
■ We have been thus particular in examining the character and nature of the decision in question to determine whether its doctrines ought to have the force of res adjudioata. We confess an obligation to adhere to former decisions of this court, and we will not, except they appear flatly in opposition to legal principles, disregard them. In our opinion, it is quite as important to have the law firmly settled as wisely settled. Oscillating decisions of a court of last resort tend to disturb the tenure of property and the rights of the people, and weaken confidence in the courts. But it will hardly do to push the doctrine of stare decisis so far as to bind this court by the opinion of less than a majority of the occupants of its bench at the time. The rules of law announced by the different Justices of this court in The City of Davenport v. The M. & M. R. Co., in our opinion, cannot be regarded as a decision of the court having the force of a precedent.
It, therefore, becomes our duty to determine the questions in-the case before us involving the liability of the defendant for the taxes upon the rolling stock upon principle and decisions of other courts, for the question has not been determined here. Of course, we will give due weight and consideration to the reasoning found in the different opinions in Davenport v. The M. & M. R. Co. treating upon the question we have now to determine.
8___. • YIII. We will first inquire whether the property in question is taxable here, being owned by a corporation existing-under the laws of another State, but doing business in this State, and using the property in the prosecution of such business. Upon this point there can be *83no doubt, for it is expressly provided by statute that all property, real and personal, within the State, not exempted by law, is subject to taxation, and “property situated in this State, belonging to any bank or company, incorporated or otherwise, whether incorporated by this or any other State,” is expressly enumerated in the list of taxable property. Eev. § 712.
9,_._. agent-IX. ' The next inquiry is, where may such property be assessed and taxed? Eev. § 714, provides for the assessment of property in the following paragraph: “ Every inhabitant of the State, of full age and sound mind, shall assist the assessor in listing all property subject to taxation in this State of which he is the owner, or has the control or management, in the manner hereinafter directed; the property of * * * * * a body corporate, company, society or partnership, by its principal accounting officer, agent or partner.” Section 725 makes other provisions as to the duty of an agent having in his possession or under his control and management, the property of another, to list the same. Section 716 directs that “any person required to list property belonging to another shall list it in the same county in which he would be required to if it were his own;” and § 719 provides that “if the owner resides out of the county, it shall be listed by the agent or person having charge of the same.” Section 734 makes it the duty of the assessor “ to list each person in his township, and to assess all the property, personal and real, therein.”
As we have before remarked, it is settled by a decision of this court, (Dunleith & Dubuque Bridge Co. v. Dubuque, supra), that the property in question is taxable under the laws of the State; if it be within the jurisdiction of the city it is subject to municipal taxation. In our opinion the statutory provision, above cited, determines that the property in question is to be listed in the city of Dubuque, and is there taxable. If it is property that may be assessed and taxed for State and county purposes in the township in which Dubuque is situated, and the officers or agents of defendant, whose duty it is to list the property, are taxable for property of like char*84acter in the city, it is very plain that it may be assessed and taxed by the city, for it is in that case “ taxable property within its limits.”
Now recurring, very briefly, to the character of the property, we remark that it consists of engines and cars used in operating the road throughout its whole length. By this we do not mean that the cars and engines are used continuously at one particular place on the road, but each one is used over the whole line’. The property is thus continually in a state of transition, and literally is in continual motion. It has, outside of Dubuque, no place of rest. The person whose duty it is to assess the property, is an inhabitant of the city of Dubuque, for the head quarters of defendant for the management and control of the -rolling stock are there. The property, in contemplation of law, is in his possession; as a matter of fact it is under his control. When elsewhere than -in the city of Dubuque, it is in motion; if not absolutely so, it is only waiting for an opportunity or occasion to move. These being the facts, it appears to us that the proper manager of defendant’s affairs is required to list the property in Dubuque.
10.-: — : ing stock. X. As a rule of law, the situs of personal property is determined by the domicile of the owner. This is true as to questions affecting the sale, distribution, and right of possession thereof. But the doctrine would not relieve such property fronr taxation under statutes of the character of those of this State above quoted, when the owner is a non-resident, and the property is within the State. This point demands no further attention.
But the doctrine is not without force and application to support the conclusion that the property in question is subject to assessment and taxation by the city of Dubuque. The officer or agent who has control of the property, stands in the place of the owner, and its situs for all purposes of taxation, unless otherwise prescribed, is his place of business. Supervisors of Tazewell Co. v. Davenport, 40 Ill., 197; Sangamon & Morgan R. R. Co. v. County of Morgan, 14 Ill., 163; British Commercial Life Ins. Co. v. Commissioner of Taxes, 31 N. Y., 32. The transitory character of the property renders *85this view necessary in order to subject it to taxation at all, and that it is not exempt therefrom we have seen, and that it ought to escape just taxation no one will claim.
A resident of the State, owning property which is used in different counties or localities, without its having in any one an actual situs, would be taxed thereon in the place of business at which he managed such property. But in case a resident owns personal property actually situated in a county different from his place of residence, he is taxed in the county where the property is found. Such is the effect of Rev., § 717. It contemplates that the property, in order to be taxed out of the county of his residence, shall be in a permanent manner used where it is assessed.
The keeper of a livery stable or the proprietor of a line of stages may have property that is transitory, actually in motion at all times when not necessarily at rest, as demanded by the nature of his animals, or for repairs of his vehicles. The situs of such property, for the purpose of taxation, is the place of business of the owner. The rolling stock of defendant is used in the same way, and is governed by the same rules. The manager or agent of defendant for the State, being required to list the property, must do so as though it were his own. His place of business is Dubuque. There his property, were it used in a like manner, would be taxable, and there must defendant’s be listed and taxed.
■ These views, we think, are supported by the following cases: Hunter v. Supervisors, 33 Iowa, 376; The Board of Supervisors v. Davenport, 40 Ill., 197; Sangamon & Morgan R. R. Co. v. The County of Morgan, et al., 14 Ill., 163; St. Louis v. Wiggins Ferry Co., 40 Mo., 582; British Com. Life Ins. Co. v. Comm’rs of Taxes, 31 N. Y., 32; Sacramento v. California Stage Co., 12 Cal., 134; People v. Niles, 35 Cal., 282; Conroe v. Nat. Protection Ins. Co., 10 How. Pr., 403; Hubbard v. Nat. Protection Ins. Co., 11 Id., 149; State v. Haight, 1 Vroom, 428; Thorn v. Cen. R. R. Co., 2 Dutcher, 125.
*86n. - — —: considered, *85XII. We will proceed very briefly to notice the objections to the foregoing conclusion raised in the opinion of the 'different Justices in The City of Davenport v. The M. & M. *86R. Co., supra. It is first said by Mr. Justice Lowe, “ that the rolling stock of a railway is a part and parcel of the road itself.” In our opinion this conclusion of law is utterly inadmissible, because it directly contaidicts facts, and we know of no legal fiction that will be permitted s > boldly to fly in the face of truth. The rolling stock is personal property; the road is real property. Sangamon & Morgan R. Co. v. County of Morgan, 14 Ills., 164. How-can the first be a part of the last? The rolling stock is used upon the road. A farmer uses his plows, horses, reapers, etc., upon his farm; the property of all is in one owner, but it could not be thought by any one that this personal property was only a part of the realty. A. wagon and team are used upon a turnpike road, and a boat upon a canal; now if, in each case, the property in the vehicle or vessel was held by the proprietors of the road or canal, then it would follow, if the conclusion of the learned and distinguished Justice he correct, that the wagon and horses are a part of the road, and the boat a part of the canal! Rut the position is so obviously untenable that nothing can be said in its refutation of more force than its bare announcement. See the case last cited for an answer to the doctrine.
XII. The conclusion of Dilt.on, J., and Weight, On. J., is based upon t-lie ground that if the property is held to be taxable by the city wherein the principal place of business of the corporation is situated, it may be taxed likewise in every other town and city on the line of the road. This result they reach upon the authority of Baldwin v. The M. & M. R. R. Co., 5 Iowa, 518, and Richardson v. The B. & M. R. Co., 8 Iowa, 260, which they cite as holding that the residence of the corporation is all along the road — in every place through which it passes. It is a sufficient answer to this equally inadmissible conclusion to say, that the cases-cited in its support relate to the place of .bringing suits against corporations, and construe statutes upon that subject. They are not upon the subject of taxation, nor do they involve any question relating thereto.
The argument, that if the corporation may be taxed in the *87city wherein are its headquarters, it may therefore be taxed by all other cities through which its road runs, may be answered by the simple statement that property can be but once taxed, and when a right is established to tax by one city, that fact itself is conclusive that no other municipality possesses the power.
It is conceded by all that justice demands all property of the State, not exempt by law, shall be subject to taxation; that no person or class of persons, whether natural or artificial, should escape the burdens of supporting the government. Corporations should have no greater exemptions in the matter of taxation than are extended to every citizen of the State. That such is the spirit and intention of the law we have no doubt. Indeed, the language of the supreme law of the State on this subject is as follows: “ The property of all corporations for pecuniary profit shall be subject to taxation, the same as that of individuals.” Constitution, Art. 8, § 2. In our opinion, the spirit of this constitutional provision is repeated in the statutes to which we have referred, and we think it was the intention of the legislature that all personal property of railroad corporations, including rolling stock, should be taxed the samé as property of like character owned by the citizens of the State.
Our views, as we have expressed them, carry out this spirit and intention which is plainly discovered in the statutes themselves, and, as they are in harmony with right and justice, we are fully satisfied with the conclusions to which they lead us.
The judgment of the court in disallowing the tax to the amount of $50 upon the depot building is correct, as the same property is covered by an assessment under another description.
The judgment of the District Court will be affirmed on defendant’s appeal, and reversed on the appeal of plaintiff.
Affirmed on Defendant’s Appeal.
