delivered the opinion of the Court.
This is a bill against the mayor and city council of Nashville to recover eighty-three dollars and five cents and interest for stationery furnished and printed for the city. The city concedes that the account is correct as to items and amounts, hut declines to receive the goods and pay the bill therefor on the ground that the stationery does not hear the union label of the Nashville Allied Trades Council, or the label enacted by the International Typographical Union.
It appears that on December 11,1897, the city council of Nashville passed the following ordinance:
Section 1. Be it enacted that all city printing shall bear the union label of the Nashville Allied Trades Council or the label enacted by the International Typographical Union.
“Sec. 2. That this ordinance shall take effect from and after its 'passage* the welfare of the city requiring it.”
It appears further that in February, 1901, the city, being in need of blank books and stationery over the value of $50, solicited competitive bidiT therefor, specifying what was desired, and complainant, being the *498lowest bidder, was awarded the contract to furnish the goods, and, under its bid and contract, manufactured the articles specified, according to specifications, and delivered some of the letter heads embraced in the order in March, 1901.
After the manufacture of all the items specified, and the advance delivery of the letter heads mentioned, the city notified complainant that it would refuse to receive the goods upon the sole and only ground that they did not bear the union label prescribed by the ordinance, and refused to pay for the goods for the same reason, and thereupon relet the work to the Brandon Printing Company at an advance price of thirty-eight and one half per cent. The bill is filed to recover the amount of complainant’s bill, and to have the ordinance in question declared unreasonable, null, and void.
The city insists upon the validity of the ordinance, and that complainants knew of its existence when they made their bid, and agreed to abide by it- in the event the contract was awarded to them, and upon both grounds deny any right of recovery.
The chancellor heard the case on proof, and held the ordinance null and void because in conflict with the provisions of the charter of the city, and gave complainant judgment for the amount of the bill and costs.
The city appealed, and in the court of chancery appeals assigned two errors: First, that the chancel*499lor erred in bolding tbe ordinance void, and that it was not in tbe power of tbe city to pass tbe same; second, that, even if tbe ordinance be beld void, tbe complainant nevertheless agreed to place tbe union label upon tbe stationery, and was bound by its agreement, and, unless complied with, it could not recover.
Tbe charter of tbe city requires that all goods and supplies furnished tbe city, amounting to over fifty dollars, must be let out at competitive biddings to tbe lowest responsible bidder.
We are of opinion that the ordinance in question is clearly in conflict with tbe spirit, purpose, and letter of tbe charter, and is invalid and void.
It is, moreover, class legislation, contrary to public policy and to tbe constitution of tbe State, because plainly discriminative in its character. All tbe authorities to which we have access so bold in regard to similar ordinances and statutes, and we have been able to find none to tbe contrary. We cite tbe following from among many others: Davenport v. Walker (Sup.) 68 N. Y., 161; Holden v. City of Alton (Ill.), 53 N. E., 556; City of Atlanta v. Stein (Ga.) 36 S. E., 932 (51 L. R. A., 335); Adams v. Brenan, 177 Ill., 194 (52 N. E., 314, 42 L. R. A., 718, 69 Am. St., Rep., 222); Fiske v. People (Ill.), 58 N. E., 985 (52 L. R. A. 291) ; State v. Loomis, 115 Mo., 307 (22 S. W., 350, 21 L. R. A., 789) ; In re Jacobs, 98 N. Y., 98 (50 Am. Rep., 636) ; People v. *500Gillson, 109 N. Y., 889 (17 N. E., 313, 1 Am. St., Rep., 465).
We give a short synopsis of several cases, to illustrate the holdings:
Holden v. City of Alton (Ill., April 17, 1899), 53 N. E., 556: The charter of the city of Alton provided that all printing and contracts for stationery should be let to the “lowest bidder” unless the amount of the contract price was under ten dollars. Charles Holden proposed at a competitive bidding, under seal, to print certain bonds for the city for eighteen dollars and twenty-five cents. The Sentinel-Democrat Printing Company bid twenty-two dollars and eighty-five cents for the sanie work. An ordinance was pending before the council, but had not become a law, to the effect that no city printing should be let to any one who could not furnish the union label. Mr. Holden could not, but the Sentinel-Democrat Planting Company could. The letting of the contract was delayed until the ordinance could be passed. This being done, the contract was let to the Sentinel-Democrat Printing Company, and the bid of Holden refused, solely and alone on the ground that he could not show the union label. Holden was a stationer of good standing, entirely responsible, and a taxpayer of the city. He filed a bill to enjoin the Sentinel-Democrat Print ing Company from carrying out the contract, and the city from paying him therefor. Nothing had been *501done in that direction when the bill was filed, but pending the final decision the city paid him anyway.
The court held that the fact that Holden was a bidder did not impair his right to bring the hill as a taxpayer. The court further said that, even if the ordinance had been approved before the bidding, the case would not have been altered; that the statute or charter required the contract to be let to the lowest bidder; and that this “implied equal opportunity and freedom in all who might choose to bid.” The court said, that while in many cases there might be ground for the exercise of discretion, here there was no attempt to exercise any discretion as to the qualification or facilities of bidders, and that a refusal upon the ground upon which I-Iolden was refused was “merely the imposition of a greater burden on the taxpayers, through an attempted abuse of power.” As the money was paid after the bill had been filed, restitution to the city was directed.
City of Atlanta v. Stein (Ga., Aug. 9, 1900), 36 S. E., 932: The charter of Atlanta does not require the public printing to be let to the lowest responsible bidder, but leaves to the municipal authorities a wide discretion.
An ordinance was passed by the city requiring all printing used by the city to bear the union label, and directing all advertisements soliciting bids to so state. Printing was advertised for, it being stated that no bids could be accepted for printing which *502could not bear the union label. There were four union and fifteen nonunion printing establishments in Atlanta at that time. The nonunion men were not allowed to bid, and evidence was introduced tending to show that they could have bid less than the lowest union bid.
The work was awarded to the Pease Printing Company, a union establishment. Thereupon, Mr. Stein filed a bill, as a citizen and taxpayer, to enjoin the execution of this contract. The injunction was granted upon the ground that the ordinance was void because it tended to defeat competition and encourage monopoly. The court said that it was “not within the power of municipal authorities to enact legislation of this kind.” This ordinance cut off the poAver to fully and freely exercise the discretion which the public good required to be exercised, and it was therefore void. The injunction was granted.
Adams v. Brenan, 177 Ill., 194 (52 N. E., 314; 42 L. R. A., 718, 69 Am. St. Rep., 222) : The board of education in Chicago entered into an agreement with a workingman’s union, known as the “Building Trades Council,” to the effect that the board would insert in all contracts for work on school buildings a provision that union men only should be employed by contractors to work on such buildings!
A schoolhouse needing repair, the board advertised for bids, inserting in the advertisement a clause to the effect that none but union labor should be em*503ployed. One Knisely put in two bids. One was for one thousand, nine hundred dollars, with the right to use either unior or nonunion labor, and the other was two thousand and ninety dollars, and use union labor only.
The board accepted the higher or “union” bid. J. L. Adams, a taxpayer, thereupon filed a bill against Knisely and the board to enjoin the execution of the contract. The injunction was granted, although the work had been begun under the contract.
The court held that, even if the provision had been inserted pursuant to an act of the legislature, it would be void; that such an act would be unconstitutional, because it would be an infringement upon the constitutional right of the citizen, and tended to 'create a monopoly and to restrict competition in bidding for Avork.
The contract was in effect an expenditure of public money for the benefit of a private organization or labor union.
Recently this identical question arose in that State. An ordinance was passed by Chicago to the effect that every bidder upon public work should agree to use only union labor, and that the contract made in pursuance of such bids should so provide.
The ordinance was declared to be void as discriminating between different classes of citizens, and as restricting competition and increasing the cost of public work. Fiske v. People (Ill.) 58 N. E., 985 (52 *504L. R. A., 291). A statute which made it a misdemeanor for any person to keep any employee from joining a labor union under a threat to discharge him was held to he void because it deprived such persons of the freedom of entering into and terminating contracts. Gillespie v. People (Ill.), 58 N. E., 1007 (80 Am. St. Rep., 176, 52 L. R. A., 283).
This ordinance in question violates section one of the fourteenth amendment to the constitution of the United States, which declares that “no State shall make or enforce any laAV Avhich shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty or property, Avithout due process of law, nor deny to any person within its jurisdiction the equal protection of the laws.”
And it violates the constitution of the State of Tennessee, art. 1, sec. 17.
This ordinance limits the right of the board of public works to contract for the public printing for such of the city’s offices as use printed matter with the union label impressed on it. It limits competition, and was so intended, and of necessity increases the price for all such work, and hence is against public policy.
In Adams v. Brenan, referred to above; the supreme court said: “There is no more reason or justification for such a contract as this than there would be for a provision that no one should be employed except mem*505bers of some particular party or church. In any such case it might be said that the board entertained a tona fide opinion that the members of some political party were more intelligent and better capable of performing the work, so that better results would be attained, or that the members of a church, on account of their higher standard of morality, would more faithfully and conscientiously carry out the contract. The fact that the board may have been of the opinion that its action was for the benefit of the public can not afford a justification for limiting competition in bidders, and requiring them to abandon the right to contract with whomsoever they may choose for the performance of the work.”
And in the same' case the court further said: “It is plain that the rule adopted by the board and included in this contract is a discrimination between different classes of citizens, and of snch a nature as to restrict competition and to increase the cost of work.”
And in Holden v. City of Alton, in a more recent decision involving the use of the so-called union label, the supreme court of Illinois said: “The council cast upon the taxpayers an increased burden . . . solely because it had entered into a combination with a certain class of persons doing printing to restrict the privilege of bidding to snch class, instead of leaving it open to all citizens upon like conditions.. Such a combination or agreement is in violation of common *506right, tends to create a monopoly, and can not be tolerated.”
This ordinance deprives those not using the union label of the right of pursuing their business avocation, to the extent that their bids for public printing will not be accepted.
In Appeal of Durach, 62 Pa., 495, the supreme court of Pennsylvania, in referring to such legislation, used the following language: “Legislation either to benefit or burden particular classes, under the idea that it is for the good of the State at large, infringes upon the natural and guaranteed right of ‘acquiring, possessing and protecting property,’ subject only to fair and equal contributions to the just and necessary expenses of a government, in the exercise of its proper and legitimate functions. A government, which assumes the office of controlling and directing the lawful industry of the citizens into the channels which it may choose to deem best, assumes what does not legitimately belong to it.”
In the case of Citizens Savings & Loan Association v. City of Topeka, 20 Wall., 655 (22 L. Ed., 455), the court said: “To lay with one hand the power of the government on the property of the citizen, and with the other to bestow it upon favored individuals, to aid private fortunes, is none the less a robbery because it is done under the form of laAV, and is called ‘taxation.’ This is not legislation. It is a decree under legislative form.”
*507In State v. Loomis, 115 Mo., 307 (22 S. W., 350, 21 L. R. A., 789), Chief Justice Black said: “Liberty, as we have seen, includes the right to contract as others may, and to take that right away from the class of persons following lawful pursuits is simply depriving such persons of a time-honored right which the constitution undertakes to secure to every citizen.”
In the case of Yick Wo v. Hopkins, reported in 118 U. S., 356 (6 Supt. Ct., 1064; 30 L. Ed., 220), the supreme court holds that the ordinance of a city which makes arbitrary and unjust discrimination between persons is a violation of the rights and privileges guaranteed in the fourteenth amendment to the constitution of the United States.
The ansAver is made that the nonunion citizen is not deprived of the right to contract for this work by this ordinance, except by his own act in refusing to join the union. So any mam could become a Democrat, a Presbyterian, or a Catholic. A.nd should a law limit public work to any one of these classes, the individual could bring himself within the privileged class by joining it. But he is hot compelled to do this.
In re Jacobs, 98 N. Y., 98 (50 Am. Rep., 636), the court of appeals said: “Liberty, in its broad sense, as understood in this country, is not freedom from actual servitude, imprisonment, or restraint, but the right of one to live and work where he will, to earn his livelihood in any lawful calling, and to pursue any lawful trade or vocation. All laws, therefore, which *508impair or trammel these rights, which limit one in his choice of a trade or profession, or confine him to work or live in a specified locality, or-exclude him from his own house, or restrain his otherwise lawful moAe-ments, except such as may he passed in the exercise by the legislature of the police, power, are infringements-upon his fundamental rights of liberty, which are under constitutional protection.”
In People v. Gillson, 109 N. Y., 389 (17 N. E., 343, 4 Am. St., Rep., 465), it was said: “It is quite clear that some one or all of these fundamental and valuable rights are invaded, weakened, limited, or destroyed by the legislation under consideration. It is evidently of that kind which has been so frequent of late, — -a kind which is meant to protect some class in the community against fair, free, and full competition of some other class; the members of the former class thinking it impossible to hold against such competition, and therefore flying to the legislature to secure some enactment which shall operate favorably to them, or unfavorably to their competitors in the commercial, agricultural, manufacturing, or producing fields.”
In Butcher’s Union Slaughter House & Live Stock Landing Co. v. Crescent City Live Stock Landing & Slaughter House Co., 111 U. S., 746 (4 Sup. Ct., 652; 28 L. Ed., 585), the court said: “A monopoly is defined to be an institution or allowance from the sovereign power of the State, by grant, commission or otherwise, to any person or corporation, for the sole buy*509ing, selling, making, working, or using of anything, whereby any person or persons, bodies politic or corporate, are sought to be restrained of any freedom or liberty they bad before, or hindered in their lawful trade. All grants of this kind are void at common law, because they destroy the freedom of trade, discourage labor and industry, restrain persons from getting an honest livelihood, and put it in the power of the grantees to enhance the price of commodities. They are void because they interfere with the liberty of the individual to pursue a lawful trade or employment.”
In Fishburn v. City of Chicago, 171 Ill., 338 (49 N. E., 532; 39 L. R. A., 482; 63 Am. St. Rep., 236), the court said: “It is a well-settled general rule that all contracts in which the public are interested which will tend to prevent competion are void;”
And in City of Chicago v. Rumpff, 45 Ill., 90 (92 Am. Dec., 196), the court said: “It is believed that the result of the authorities Avarrants the assertion that corporate franchises, whether municipal or private, are conferred in trust for the benefit of the entire body of corporators, and must, like all trusts, be exercised with prudence and discretion. Hence their by-laws must be reasonable; and such as are vexatious, unequal or oppressive or are manifestly injurious to the interest of the corporation, are void, and of the same character are all by-laws in restraint of trade, or which necessarily tend to create a monopoly.”
*510And to the same effect is People v. Chicago Gas Trust Co., 130 Ill., 268 (22 N. E., 798, 8 L. R. A., 497, 17 Am. St. Rep., 319); Foss v. Cummings, 149 Ill., 353 (36 N. E., 553).
In City of Cairo v. Feuchter, 159 Ill., 155 (42 N. E., 308), the court said: “A city ordinance which unjustly discriminates between persons coming within the same class, and imposes burdens on some from which others are by its terms exempt, is void.”
The ordinance under discussion does not undertake to fix a standard of quality, but it singles out a certain class, and requires the board of public works to purchase from that class, and from no other. This is an arbitrary descrimination, and the city has no authority or power to pass such an ordinance. City of Chicago v. Rumpff, 45 Ill., 90 (92 Am. Dec., 196) ; Tugman v. City of Chicago,78 Ill., 405; City of Hannibal v. Missouri & K. Tel. Co., 31 Mo. App., 23, 32, 33; Allgeyer v. Louisiana, 165 U. S., 578, 589 (17 Sup. Ct., 427, 41 L. Ed., 832); Yick Wo v. Hopkins, 118 U. S., 370, 371 (6 Sup. Ct., 1064, 30 L. Ed., 220); 1 Dill. Mun. Corp., (4th Ed.) sec. 322; Kansas City v. Button, 52 Mo. App., 398, 400; River Rendering Co. v. Behr, 77 Mo., 91 (46 Am. Rep. 6) ; City of St. Louis v. Russell, 116 Mo., 248, 258 (22 S. W., 470, 20 L. R. A., 721) ; Eden v. People, 161 Ill., 296 (43 N. E., 1108, 32 L. R. A., 659, 52 Am. St. Rep., 365).
The various reasons assigned in these cases are that *511such, ordinances tend to create a monopoly; that they are class legislation, discriminative in their character; that they prevent parties from an equal enjoyment of their property and business, and deprive persons of their property rights, in violation of the constitution, by restricting trade and the free use of property on equal terms with others.
Municipal corporations have power to pass ordinances, but, in order to he enforceable, they must be legal, reasonable, constitutional, and not contrary to valid charter provisions; and, if they do not comply with these requirements, they will be set aside by the courts as invalid and illegal. The basic idea underlying all these decisions is that municipal powers are delegated to, and held in trust by, the corporation, to be exercised for the benefit of all the inhabitants of the municipality, equally and impartially. 1 Dill. Mun. Corp., 3556; People v. Armstrong (Mich.), 16 Am. St. Rep., 584, note, s. c. 41 N. W., 275, 2 L. R. A., 721; Anderson v. City of Wellington (Kan.), 19 Pac., 719 (2 L. R. A., 110, 10 Am. St. Rep., 175) ; Ward v. Mayor, 35 Am. Rep., 702 note; Robinson v. City of Franklin, 34 Am. Dec., 633 note; City of Tarkio v. Cook (Mo.), 25 S. W., 202, 41 Am. St. Rep., 678; Champter v. City of Greencastle (Ind.), 35 N. E., 14, 24 L. R. A., 768, 46 Am. St. Rep., 390; Long v. Taxing Dist., 7 Lea, 137 (40 Am. Rep., 55), and cases cited; Smith v. City of Knoxville, 3 Head, *512245; Maxwell v. Jonesboro, 11 Heisk., 257; Trigally v. City of Memphis, 6 Cold., 382.
The provisions of the charter are mandatory, and must he obeyed hy the city and its agents; and, if in conflict with an ordinance, the charter must prevail. Worthington v. City of Boston, 152 U. S., 695 (14 Sup. Ct., 737; 38 L. Ed., 603); Zottman v. City and County of San Francisco, 81 Am. Dec., 96; Whitney v. Village of Hudson, 69 Mich., 189 (37 N. W. 184) ; McDonald v. City of New York, 23 Am. Rep., 144; City of Lancaster v. Miller, 58 Ohio St., 558 (51 N. E., 52); Addis v. City of Pittsburg, 85 Pa., 379.
It is insisted, however, for the city, that, if the ordinance is invalid (and its invalidity is now virtually conceded), still the complainants contracted to. furnish the material with the label upon it, and, not having complied with this contract, they can not recover upon it.
Complainants insist that the requirement of the label was a nullity, and, as a matter of fact, did not constitute a part of their bid as it was made and accepted, and the contract having been awarded to them, and the material having been furnished, in all respects complying with the specifications, except the label, they are entitled to disregard the void and illegal requirement, and recover for the goods. The advertisement of the city for the work contained notice that “all work, before acceptance, must have the union labek”
*513In making their bid, the complainants specified the goods to be furnished, item by item, and offered to furnish such goods, but made no express stipulation to attach the union label; and they insist that the latter stipulation is not part of the specification, and was not assented to and made a part of the contract.
The court is of opinion that the provision in the contract and advertisement that the goods would bear the union label was invalid, illegal and void, and that bidders were not bound by the provision, hut might ignore the same in making their bids, and refuse to comply with the same in executing their contract. The majority of the court is further of opinion chat the insertion of this provision in the contract and advertisement can not, in the absence of proof, he presumed to have interfered with the competitive bidding, since all bidders must be assumed to have known that the provision was illegal and could not be enforced.
This being so, the contract and bidding must be treated as though no such condition was attached to them, and the complainants having made the lowest bid, and having been awarded the contract, and having executed the same in all respects according to the specifications, except the requirement as to the label, the city is legally obligated and bound to accept and pay for the goods, and complainants are entitled to recover the stipulated price; and the decree *514of the court of chancery appeals is reversed, and the decree of the chancellor is affirmed, and the city will pay all the costs of the same.
