This was a bill in chancery, originally filed in the circuit court for Wayne county, Mich., by the city of Detroit, against the Detroit City Kailway, the Detroit Citizens’ Street-Railway Company, Sidney D. Miller and William K. Muir, trustees, and the Washington Trust Company of the City of New York. The defendants all answered in the state court, and then, on the petition of the Washington Trust Company, the case was removed to this court on the ground of local prejudice. See City of Detroit v. Detroit City Ry. Co., 54 Fed. Rep. 1. The case was heard on hill and answer.
’Fire object of the hill was to obtain an injunction, mandatory and prohibitory, to compel the Detroit Citizens’ Street-Railway Company, operating a street railway in that city, to remove its tracks from the streets, and to prevent its further running of cars after May 9,1893. The case set out in the bill was that the easement of the Citizens’ Company to occupy the streets ended upon that date, and that the easement until 1909, claimed by the Citizens’ Company under assignment of mesne conveyance from the Detroit City Railway, was invalid, because the city council had no power, under the laws of Michigan, to confer a,n easement upon the Detroit City Railway to last beyond its corporate life, which ended May 9, 1893. The answers of the several defendants Avhose interests are stated below, after denying the claim of the hill that the grant to the City Railway of the easement until 1909 was invalid, and, after pleading estoppel against the city on two grounds, prayed that the answers might be treated as cross bills; that an ordinance of the city council of 1892, purporting to repeal the 1909 grant, should he decreed invalid, as impairing contract obligations; and that the city and its officers should he enjoined from interfering with the lawful occupation of the streets by the Citizens’ Company. The facts to he gathered from the answers and the hill were as follows:
By ordinance approved tin» 24.1 h of November, 38(52, the common council of the city of Detroit conveyed to one Wilcox and associates, their successors and assigns, who should form a corporation for that purpose, the exclusive right to construct, maintain, and operate a street railway, with a single or double track, for 30 years from the date of the ordinance, upon certain named streets of Detroit, and upon such other streets as the common council might direct, and the company assent to, in wilting, provided, that if the assent of the company was not forthcoming within 80 days the council might then give the privilege to any other company. The ordinance provided that the track should be laid in such a way as least to obstruct *870public travel; that if it should become necessary to relay the tracks, in case the city graded, paved, or' repaved the streets, the relaying-sbould be done at the expense of the company; that the company should be required to keep the surface of the streets, inside the rails, and-for two feet four inches outside thereof, in good order and repair, provided that on the paved portions of the streets the materials for repaving should be supplied at the expense of the city; that the railways within the named streets should be completed within certain fixed times, or in default thereof the rights conferred would be lost therein; that the company should pay to the city, after five years, the annual license fee of f 15 a car; and that rights conferred on Wilcox arid his associates should vest, without further act or consent of the city, in the corporation they proposed to form. The ordinance was accepted by the grantees or their successors, who on May 9, 1863, organized the corporation as the Detroit City Railway, with a corporate life of thirty years.
The company built the railways required in the ordinance of 1862, and continued to operate them until 1879. In the mean time two other railway companies, under ordinances of the city, built lines of road on certain streets, after the Detroit City Railway Company had declined to do so. They were known as the Detroit & C-rand Trunk Junction Street Railway, and the Central Market, Gass Avenue & Third Street Railway. They became embarrassed, and their property and franchises were sold under mortgages, and new companies were organized to operate them. The successor of the former, the Congress & Baker Street Railway Company, was organized September 17, 1875, and the successor of the latter, the Cass Avenue Street-Railway Company, was organized August 18, 1S77, each for 30 years. The ordinances under which these companies operated required them, in case the city paved or repaved the streets they' occupied, to repave, at their own expense, all of the portion within the track; and two feet nine inches on either side thereof, and imposed a car license of $25 on each double horse car, and $12.50 on each single horse car, and a special tax for the second five years of the ordinance of 1 per cent, on the gross earnings, and after that of 3 per cent.
The city became dissatisfied with the taxes it was receiving in 1879, and, after negotiating between the three companies and the city, an ordinance was passed on November 24th of that year, the validity of which was the main controversy in this action. The first and second sections of the ordinance required certain extensions on the routes of the Detroit City Railway and the Detroit & Grand Trunk Junction Railway. Section 3 repealed the ordinances of June 13,1873, and of June 16,1875, granting authority to the Detroit & Grand Trunk Junction Street-Railway Company and to the Central Market, Cass Avenue & Third Street Railway Company to construct and operate street railways through certain streets of Detroit, and provided that the said railways, constructed and operated under those ordinances, should hereafter be subject to, and operated under, the ordinance approved November 24, 1862, and its amend-*871inents, granting to Hie Detroit City Railway Company rights as Therein sot forth. The fourth section imposed a tax of 1 per cent., half-yearly, on the gross receipts of the companies, and required them to repave between the tracks when the city repaved, but not outside of the tracks, and stipulated that the tax and repaving should be in lieu of license and other taxes and charges for paving under existing ordinances. Section 5 provided that:
"Tiie powers ¡uni privileges conferred and obligations imposed on ilxe Detroit City Hail way Company by the ordinance of November 24, 1862, and the amendments thereto, are hereby extended and limited to thirty years from this date.”
The ordinance was to take effect on writ,ten acceptance of the railway companies. Such acceptances were tiled by the Detroit City Railway Company, (lie Congress & Baker Street Railway Company, and the Cass Avenue Street Railway Company. In 1882 the two other companies conveyed all their property and franchises to the Detroit City Railway. In 1887, after an attempt by the city to collect additional taxes, upon a repeal by the legislature of a section in the incorporating act (hat had imposed on such railways a tax of half of 1 per cent, on the capital stock paid in, in lieu of all other taxes, a. compromise was effected and embodied in an ordinance, confirming the ordinance of 1879, fixing the tax, in lien of all other taxes by the city, at per cent, on gross earnings from 1882 until 1S9G, and 2 per cent, thereafter, and providing that the company should pay the same municipal taxi's on all its lands and buildings as were imposed on individuals. The city thereafter attempted to collect, in addition to the taxes under the ordinance of 1887, taxes, under the general laws, upon the value of the 'tracks, horses, cars, machinery, and other personally. In an action for the additional taxes the supreme court of "Michigan gave judgment against the city, holding that the city was bound by the agreement, as to taxes contained in the ordinance of 1887. City of Detroit v. Detroit City Ry. Co., 76 Mich. 421, 43 N. W. Rep. 447.
From 1880 to 1889 the city council, by several ordinances, gave authority to the Detroit City Railway to extend its lines under the ordinance of 1879; and much capital was invested in those extensions, and in repaving Huí streets, under the obligations of, and on the faith of, the validity of the ordinance, and the duration of its grant until 1909. "In January, 1890, the Detroit, City Railway transferred its property and franchises, by way of mortgage, to Miller and Muir, trustees, to secure bonds amounting to $1,000,000. In December, 1890, the Detroit City Railway' Company transferred all its property and franchises to the Detroit Street-Railway Company, a corporation organized for 30 years from December 1, 1890. On September Iff, 1891, the Detroit Street-Railway Company conveyed all its property and franchises to the Detroit Citizens’ Street-Railway Company, a corporation organized September 2, 1891, for 30 years, and on the same day the Detroit; Citizens’ Street Railway Company conveyed the same property and franchises to the Washington Trust. Company, of Few York, in trust', to secure the payment *872of $3,000,000 of bonds. On March 29, 1892, the common council passed an ordinance, which was approved by the mayor, repealing.so much of the ordinance of 1879 as extended the rights of the Detroit Oity Bailway in the streets until 1909, and shortly after this bill was hied.
Four questions arise in this ease:
(1) Did the common council of Detroit, on the 14th of November, 1879, have power to extend the rights and privileges conferred by the ordinance of November 24, 1862, for 16 years beyond the life of the corporation upon which such right was conferred?
(2) Conceding the invalidity of the ordinance, are the parties in pari delicto, so that a court of equity will not lend its aid to the city, by mandatory and prohibitory injunction, to restore to it the rights it parted with by an ultra vires act?
(3) Is the former litigation between the Detroit City Eailway Company and the‘city of Detroit, with reference to taxation under the ordinance of 1879, res adjudicata, so that thereby the city is estopped from denying the validity of the extension under that ordinance?
(4) Does the investment of capital on the faith of the validity of the ordinance granting such extension, and in discharge of the obligations of the street-railway company assumed as a consideration for such extension, estop the city from now seeking to annul the same?
1. The power of the city to grant the extension in the ordinance of 1879 is asserted by the defendants to exist under both the charter of the city, and also under the street-railway acts.
It may be well, in advance, to settle the rule which must govern the court in construing the statutes which are claimed to confer the powers of the city with reference to street-railway grants. In the first place, the street-railway laws are general statutes, affecting all street-railway corporations in the state. Clearly, therefore, the peculiar hardships which one construction will work to a particular company, because it may have expended large amounts of money on the faith of the correctness of another and different construction, cannot be permitted to affect the view which the court shall take. It might be otherwise if it were shown that such a construction prevailed generally in the state, and that money had everywhere been invested on the faith of it.
In the second place, the principle of construction with respect to the powers of municipal corporations was laid down by the supreme court of the United States in Minturn v. Larue, 23 How. 435, in the words of Mr. Justice Nelson, as follows:
“It is a well-settled rule of construction of grants by the legislature to corporations, whether public or private, that only such powers and rights can be exercised under them as are clearly comprehended within the words of the act, or derived therefrom by necessary implication, regard being had to the objects of the grant. Any ambiguity or doubt arising out of the terms used by the legislature must be resolved in favor of the public. This principle has been so often followed in the construction of corporate powers that we need not stop to refer to authorities.”
See, also, Ottawa v. Carey, 108 U. S. 110, 2 Sup. Ct. Rep. 361, and Barnett v. Denison, 145 U. S. 135-139, 12 Sup. Ct. Rep. 819.
*873Tlie contention of counsel for defendants seems to be tbat the rubí above stated does not obtain in Michigan, because a local self-government, which has always existed in the state, and is preserved by the constitution of 1850, gives the cities inherent power independent of the legislature, which can only regulate the exercise of that power, but cannot take away or destroy it.
The constitution of Michigan provides, (article 15, § 13:)
“Tlie legislature sliall provide for the incorporation and organization of cities and villages, and shall restrict their powers of taxation, borrowing money, contracting debts, and lending their credit.”
Article 4, § 38:
‘'The legislature may confer upon organized townships, incorporated cities and villages, and upon the board of supervisors of 1he several counties, such power of local legislativo and administrative character as they ma,y deem proper.”
Article 4, § 23:
“The legislature shall not * * * vacate nor alter any road laid out by commissioners of highways, or any street in any city or village, or in any incorporated town plat.”
It is quite clear from the foregoing that Michigan does not differ from other states in this: that a municipal corporation cannot exercise any power not authorized by legislative act. Michigan is, however, peculiar, in that its legislature cannot, by mandatory act or by state agents, control the administration of what are properly local affairs in cities, townships, and counties. When the legislature acts in such matters, it can only do so by conferring discretionary power upon the local corporations. Tn other words, the provisions of the constitution of Michigan, the peculiar effect of which has been so vigorously pressed upon the court by defendants’ counsel, are merely restrictions upon the manner in which tbe leg-isla ture shall confer powers on municipalities, when it sees fit to do so. But the provisions do not, of themselves, create any power in Ihe cities or other local municipal corporations. That is left to the legislature. No case cited from the Michigan Reports is in,conflict with this view. See the opinion of Justice Cooley in the case of Board of Park Com’rs v. Common Council of Detroit, 28 Mich. 228. There is no reason, therefore, why tin» strict rub' of construing the powers of municipal corporations should Tbe departed from in Michigan. We have the highest authority for this conclusion. In she case of Taylor v. Railway Co., 80 Mich. 77, 45 N. W. Rep. 335. where the effect of a legislative grant of power to a city in reference to street railways was under consideration, Justice Grant;, speaking for the supreme court, of Michigan, said:
“Municipal corporations derive (heir sob' source of power from legislative enactments. The rale lias long been unquestionably established tbat municipal corporations are limited to those powers which are granted — First, in express words: second, necessarily incident to the powers expressly granted; and. third, those which are essential and indispensable to the declared objects and purposes of the corporation. 1 Dill. Mun. Corp. 89.”
With the rule of construction thus established, we proceed to inquire what powers, if any, the city derives from its charter to authorize the laying of railways in the streets. It is important to *874determine this, because, if the charter does not authorize the grant in question, then we must find the power asserted either within the four corners of the street-railway act, to be hereinafter considered, or not at all. Under the charter the city council of Detroit is given power “to- establish, open, widen, extend, straighten, alter, vacate and abolish highways, streets, avenues,” etc., within the city limits, and to grade, pave, repair, and otherwise improve the highways, streets, avenues, etc., “with stone, brick or other material,” and “to prohibit the encumbering of the streets,” and “to prescribe, control and' regulate the -manner in which the highways, streets, avenues,” etc., “shall be used and enjoyed.” Laws 1869, p. 1692, § 22, pars. 11, 13. The same provisions were in the revised charter of Detroit of 1857, (Laws 1857, p. 73,) and substantially similar authority was vested in the council under the charter of 1827 and its amendments, (2 Terr. Laws Mich. pp. 345, 346, §§ 18, 20; 3 Terr. Laws Mich. p. 938, § 2.) These powers are strictly legislative. What one council shall deem to be wise, and do, another council, in its wisdom, may undo. If one council shall open a street, another may vacate it. If one council shall improve a street with stone, another may tear up the stone, and put down brick. If one council ordains that wagons of a certain hundredweight, and with certain width of tire, may use certain streets, another council may determine that the tires must be wider, or the weight less. This is regulation of the use of the streets.
¡ The supreme court of Michigan has decided that a street railway, whether the motive power be horse or electricity, is not an additional' servitude of the street, which the abutting property holders can enjoin, if the railway has been authorized by the legislature and the city council. People v. Ft. Wayne & E. Ry. Co., 92 Mich. 522, 52 N. W. Rep. 1010; Dean v. Railway Co. (Mich.) 53 N. W. Rep. 396. It would seem to follow that under the general power to regulate the use of the streets the city council might permit or license a street-railway company, if it has the requisite franchise from the state, to lay its tracks in the streets and to run its cars thereon. But this would only be in the exercise by the council of legislative power. The same council, or a succeeding one, might, in its discretion, revoke the license. It must be so, because it is well established that in such subordinate legislative bodies it is not permitted to one to abridge the legislative power of its successors without express sanction of law. The first council permits a railway in a street because it is of opinion that such a use will best conduce to the public interest. When another council succeeds, it may conclude that the conditions have changed; that other, more important, traffic in the street is interrupted and blocked by street cars confined to one or two rigid tracks; and that it would serve the public interest as well to have the tracks laid in a parallel street. Under the exercise of its legislative power to regulate the use of the street, unless limited or abridged, the second council could require the removal of the tracks. The fact that, if permitted by the council, the continuance of the tracks and railway there would not be *875?.!• additional servitude, of which the abutting property owners could complain, has no bearing whatever on the discretion of council to refuse to permit the continuance of such use. It necessarily follows, having regard to the strict rule of construction already discussed, that while, under its legislative pdwer of regulating the use of the street, couucil may permit a railway to be laid in the streets, it cannot, by virtue of that power, agree that shell a use shall continue for 30 years. This is the exercise, not of a legislative, but of a contractual, power. It is an abridgment of the legislative power by contract. It is the grant of a vested right in the streets to the railway company, whereby, for 30 years, it shall have a private ownership in tracks in situ, and the exclusive right to run cars over them. Never, until street cars were adopted, was such an exclusive right in the surface of the streets permitted. The power io control Hie use of the streets bad always been in municipalities, but it had never been exercised to grant such an easement.
But it is said that Hie investment required would render it impossible to build a street railway, if Hie right to continue its use were dependent on a revocable license. That may be true, and it is a good reason why one council should be given the right to abridge the legislative power of another by contract and grant; but it furnishes no ground for saying, in the absence of such legislative authority, that a right to legislate is a right to contract. A distinction should herb be raleen between the right of a city to permit the laying of gas pipes in the streets, and the laying of rails therein. The usual power conferred in a charter, with respect to lighting cities, is that the city shall have power to provide for the lighting of streets. Under this the city may do the lighting itself, or it may contract with a company to do it, and the implication would seem reasonable that it might, by contract with a gas company, secure to the company the right to lay its pipes in the streets,, and keep them there for a number of years. It will be observed, however, that the usual power of the city, under its charter, is not to provide street railways. If it were, it would justify a very different implication from that founded on a mere legislative power to say how the streets shall be used. Another distinction is that the easement to be conferred in the case of a street railway is on the surface of the street, where public travel is, while the gas pipes are laid under the shwts, and do not affect travel in the slightest degree. The ordinance in question attempts to confer the exclusive right to occupy the streets with a railway for 30 years. It is settled beyond controversy that such a right cannot exist, except by direct and express authority from (he legislature. Jackson County Horse R. Co. v. Interstate Rapid Transit Ry. Co., 24 Fed. Rep. 306; Saginaw Gas-Light Co. v. City of Saginaw, 28 Fed. Rep. 529; Grand Rapids E. L. & P. Co. v. Grand Rapids E. E. L. & F. G. Co., 33 Fed. Rep. 659. But it may he justly said that the issue in this case does not involve the question whether the city can contract with one railway company that it will not permit another to occupy its streets, because, even if the grant of 1879 *876were void, so far as its exclusive character is concerned, it might still be valid to the extent of allowing the grantee to occupy the streets for the term of years, named, and this would require that the relief prayed for in the bill herein should be denied. The power of the city to increase the tracks in a street so as to interfere with travel is limited, (Grand Rapids St. Railways, 48 Mich. 433, 440, 12 N. W. Rep. 643;) and in many streets the laying of a double track, and its use, might practically exclude any other company. But only to this extent does the exclusiveness of the grant have any bearing on the question now under discussion.
The right of a city council, under its general control of the streets, to grant an irrevocable easement for the laying of tracks and running of cars, has several times been considered by courts of last resort in this country; and the great weight of authority is in favor of the view that such power does not include authority to Convey a vested right in the streets for years, or in perpetuity. Judge Billon, in his work on Municipal Corporations, used this language in section 724, (4th Ed.:)
“As respects ordinary railways operated by steam, and street railways operated by animal power, legislative authority is necessary, to warrant them to be placed in the streets or highways. The legislature may delegate to municipal or local bodies the right to grant or refuse such authority. The usual powers of a general nature in. municipal corporations over streets are not sufficient to confer upon them the right to authorize the appropriation of streets bv ordinary railroads which connect different towns, whose tracks are constructed in the usual manner, - and whose trains are propelled by steam. But it is otherwise as respects horse railways. They are for local travel, and the ordinary powers of municipal corporations are often ample enough, in the absence of express or other legislation on the subject, indicating a different intent, to authorize them to permit, or refuse to permit, the use of the streets within their limits for such purposes.”
If in this, as is probable, the learned author is only referring to the fact that the use of the streets for street railway purposes is not an additional servitude, and may be licensed or permitted, in the discretion of the governing body of the city, under its legislative power of regulating the use of the streets, then he is. sustained by all the authorities; but if he is to be understood as mean-' ing that under such a power a city can irrevocably grant, for a term of years, to a street-railway company, an easement in the streets for its tracks and cars, the statement is in conflict with nearly all of the decided cases.
It is hardly probable that Judge Dillon’s language is to be given the meaning claimed for it by counsel for the defendants, because in another section, in the same chapter, he emphatically approves the language of Judge Comstock in the case of Davis v. Mayor, etc., 34 N. Y. 506, expressly negativing the power of a city council having general control and regulation of the use of the streets to make an irrevocable grant of an easement therein to construct and operate a street railway. In Davis v. Mayor, etc., supra, and in Milhau v. Sharp, 27 N. Y. 611, the same resolution of the common council of the city of New York was under consideration. It purported to grant to Jacob Sharp and his associates the right to construct and *877operate on Broadway, in tbe city of New York, a double-tracked street railway. It did not contain any stipulation by tbe city that it would not in tbe future grant similar rights in tbe same street to other persons. Two questions arose in tbe case: First, bad tbe city the right to confer the power upon the grantees named in the' resolution to maintain and operate a street railway, and collect tolls therefor? and, second, had the city council the right to convey an interest in the streets by contract? It was held by a majority of the court that, if the resolution were valid, it would confer a perpetual easement in the streets. Judge Comstock was of the opinion that the city had the right, by revocable license, under its general control of the streets, to permit a street railway to lay its tracks, and run its cars, but that it had no power, by contract or grant of a vested easement, to abridge its legislative control over the streets. Wright and Johnson, JJ., were of the opinion that, while the resolution was invalid as a contract, it was valid as a license revocable at pleasure, while the other five judges, including Denio and Comstock, held that the resolution was void for the reasons given by Comstock, J. In Milhau v. Sharp it was held (Judge Selden delivering the opinion) that the resolution was objectionable, both because it created a franchise which could only come from the state, and also because it involved the grant of an interest in the street, and a consequent abridgment of the future legislative power of the city to regulate the use of the streets. See, also, People v. Kerr, 27 N. Y. 188, and Coleman v. Railroad Co., 38 N. Y. 201. The effect of these cases cannot be explained away by the perpetual character of the grant therein contained.
They do and must rest on the principle that tbe power to make an irrevocable grant, either for years or forever, is not conferred on the city, under its general legislative power. This is apparent from the language of Mr. Justice Clifford in People’s Passenger R. Co. v. Memphis City R. Co., 10 Wall. 38, where, after discussing the want of power in the municipal corporation to grant franchises for 25 years, he said:
“Snell corporations arc usually invested witli tlie power to lay out, open, alter, repair, and amend streets witliin tlie corporate limits; hut the rule is well settled that by virtue of those powers, without more, they cannot grant to an association of persons the right to construct, and maintain for a term of years, a railway in one of the streets of tlie municipality, for the transportation of passengers for private gain, and that resolution or ordinance of the authorities granting such a right is void.”
Citing Milhau v. Sharp, 27 N. Y. 611; People v. Kerr, Id. 188; and other cases, — the learned justice continued:
“Special powers are given to such corporations to lay out, open, and repair streets, as a trust to be held and exercised for the benefit of the public, from time to time, as occasion may require; and the general rule is that those powers cannot be delegated to others, nor be effectually abridged, by any act of the municipal corporation, without tlie express authority of the legislature.”
The same principle has been announced in State v. Trenton, 36 N. J. Law, 79; in Louisville City Ry. Co. v. Louisville, 8 Bush. 415, 421; in Covington St. Ry. Co. v. Covington, 9 Bush, 127; in Eichels *878v. Evansville St. Ry. Co., 78 Ind. 261; in Denver & S. Ry. Co. v. Denver City Ry., 2 Colo. 673; Memphis City R. Co. v. Memphis, 4 Cold. 406; and in Nash v. Lowry, 37 Minn. 263, 33 N. W. Rep. 787; and Boston v. Richardson, 13 Allen, 146, 161.
The only cases brought to the attention of the court, in which a different doctriné has been announced, are Brown v. Duplessis, 14 La. Ann. 842, and State v. Corrigan Consolidated St. Ry. Co., 85 Mo. 274. In the first of these the supreme court of Louisiana held that a city might sell an easement in its streets to an individual for a term of 20 years, to construct, maintain, and operate a street railway, under its general power to regulate the use of its streets; but it should be said that there was a statute in Louisiana providing that no railroad, plankroad, or canal should be constructed through the streets of any incorporated town without the consent of the municipal council, and this was held by the court to imply the power by the council to give a consent in the nature of an easement. In State v. Corrigan Consolidated St. Ry. Co., 85 Mo. 263, the supreme court of Missouri held that, where a street railway was incorporated by special act for the purpose of constructing and operating a horse railway over the streets of Kansas City, the city had, under its general charter, power to open, grade, and improve its streets, the authority to grant to the street-railroad company the right to construe!; and operate a street railroad on the various streets of the city for the period of 20 years. Of the cases cited in the opinion, only Brown v. Duplessis, already referred to, supports the doctrine. Moreover, it is to be said, in regard to the Missouri case, that the special act authorizing the construction of a railroad in the streets of Kansas City gives the case a somewhat peculiar phase, for it might be strongly argued that the act conferred, by implication, upon the city, the power to consent to tbe railway’s construction and operation, because the legislature would hardly, by special act, create a corporation to do that in a city which, under the laws of the state, the city would have no power to agree to.
The case of Atchison St. Ry. Co. v. Missouri Pac. Ry. Co., 31 Kan. 661, 3 Pac. Rep. 284, is relied on by defendants, but it by no means supports their claim. There the supreme court of Kansas held that a steam-railroad company could be enjoined from interfering with a street railway laid in the street of a city, which, without other power than that involved in the general control of the streets, had passed an ordinance purporting to give the proprietors of the railway an exclusive easement in the streets for a term of years. Justice Brewer put the decision on the ground that the railway was lawfully in the street under the license of the city, and expressly disclaimed a purpose to decide that a vested interest in the streets could be conferred by the city for years. See, also, Jackson County Horse R. Co. v. Interstate Rapid Transit Ry. Co., 24 Fed. Rep. 306. The question has never been expressly passed on by the supreme court of Michigan. In the case of Taylor v. Railway Co., 80 Mich. 77, 45 N. W. Rep. 335, however, the question was how far *879tbe village of Bay City might, in its grant to a street railway of tiie right to use its streets, secure to the railway company as by contract the right to lay the track, without payment of damages to abutting property owners, and thus exempt the company from a liability to abutters for damages imposed by a charter given to the city subsequent to the railway grant. The power to create such exemption by contract was claimed under the general power of the city (then the village) of Bay City to lay out and establish, vacate, open, make, and alter such streets as it might deem necessary for the public convenience; and Justice Grant dismisses the claim with (he significant remark, “No mention is made in the act of (.ram or street railways.-’
It follows from what has been said that the power to make the grant relied on by defendants in this case must be found in the tram or street railway acts, or not at all, and we may now proceed to examine that legislation:
The original tram-railway act of 1855 provided for the organization of companies to construct a, railway from one town to another, not upon streets, but upon private property to be acquired by purchase or condemnation. The intention of ihe act, evidently, was that the tracks should be used by members of the public, with, their own cars or carriages, upon payment of tolls fixed in the act. The motive power was limited to that of the horse or other animal. The corporators were required to file articles of association, stating, among other things, the duration of the corporation, which should not exceed 30 years. In 1861 additional sections were added, as follows:
■•Sec. It shall he competent for parties to organize companies under This act to construct and operate railways in and through the streets of any town or city in the state. Sec. 34. All such companies formed for such purposes shall have the exclusive light to use the same, provided, however, that no such company shall he authorized to construct; a railway under this act. through the streets of any town or city without the consent of the municipal authorities of said town or city, and under such, regulations and upon such terms or conditions as said authorities may from time to time proscribe." haws 1801, pp. 11. 12.
In 1807 the following additional proviso was added to section 34:
“Provided further, that, after said consent, shall have been given and accepted by the company or corporation to which the same is granted,' such authorities shall make no regulations or conditions whereby the rights or franchises so granted shall be destroyed or unreasona bly impaired, or such company or corporation be deprived of the rigid, of constructing, maintaining and operating such railway in tiie street in such consent or grant named pursuant to the terms thereof.” [jaws 18(i7, p. 257.
The ordinance of 187!) was passed after the general street-railway act of 1867 was enacted, and (he latter contained a provision that it should have application to all street railways organized previous to its passage. It is not contended that any change was made in the general act which would affect the operation of the above language; but section 13 of that act, which covers the same subject, may be quoted:
"Any street railway corporation organized under the provisions of this act, may, with the consent of the corporate authorities of any city or vil*880lage, given in and by an ordinance or ordinances duly enacted for that purpose, and under such rules, regulations and conditions as in and by such ordinance or ordinances shall be prescribed, construct, use, maintain and own a street railway for the transportation of passengers in and upon the lines of such streets and ways, in said city oT village, as shall be designated and granted from time to time for that purpose, in the ordinance or ordinances granting such consent; but no such railway company shall construct any railway in the streets of any city or village-until the company shall have accepted in writing the terms and conditions upon which they are permitted to use such streets, and any such company may extend, construct, use and maintain their road in and along the streets and highways of any township, adjacent to said city or village, upon such terms and conditions as may be agreed upon by the company and the township board of the township, which agreement and the acceptance by the company of the terms thereof, shall be recorded by the township clerk in the records of his township.”
There has been much discussion at the bar concerning the character of the rights which the city, under the acts, confers upon the railway companies, in giving its consent as therein required. An examination of the briefs does not disclose any real difference between counsel upon this point. The franchise to construct and operate a street railway is conferred by the legislature upon any persons who organize as a corporation under the act, and file articles as required. The function of the city, under the act, is merely to consent, upon conditions, that the companies may exercise the state-given franchise in its streets. Similar statutes have been before other courts, and this is the view which has always been taken in respect to the city’s, function under them.
In Chicago City Ry. Co. v. People, 73 Ill. 541, where the construction of a similar statute was under consideration, the supreme court of Illinois said:
“It is a misconception of tbe law to suppose that the railroad company derived its power to construct a railroad from any ordinance of the city. All its authority is from the state, and is conferred by its charter. The city has delegated to it the power to say in what manner, and under what conditions, the company may exercise the franchise, conferred by the state, but nothing more.”
And the same view is taken by the supreme court of Michigan in the case of People v. Mutual Gaslight Co., of Detroit, 38 Mich. 154; People v. Ft. Wayne & E. Ry. Co., 92 Mich. 522, 52 N. W. Rep. 1010; Sims v. Railroad Co., 37 Ohio St. 566; National Foundry & Pipe Works v. Oconto Water Co., 52 Fed. Rep. 29.
The first proviso of section 34, requiring the consent of the city, is a limitation upon the franchise to construct' and operate, conferred in the granting section, No. 33. The office of a proviso is usually that of limitation. Minis v. U. S., 15 Pet. 423, 445. It here introduces a limitation in two ways: First, by making the franchise operative only on consent of the city; and, second, by allowing the city, in giving its consent, to surround the exercise of the franchise with such further limitations as it may choose to impose. As we have seen, no power exists in the city, outside of the railway acts, to grant a vested easement in the streets. The power to' consent, which is indirectly conferred by the section 34, necessarily implies the power to grant the easement. But a power *881implied must be limited to the necessity which gives rise to its implication.
An inevitable limitation thus arising is that the easement shall not endure beyond the life of the franchise for which the easement, is given. I cannot escape the conclusion, which seems to me clear to a demonstration, that the power of consent to be exercised by the city under the statute is limited in time to the life of the franchise to he consented to. The acts of the state and city, together, in granting the franchise, and consenting to its exercise, are equivalent t.o the grant of a franchise by a state legislature, under a constitution which permits it, to a company to lay its railway in certain named streets of a city, and to operate the same, without, the intervention of the city in the matter. Under a franchise of the hind supposed, such easement in the streets would pass to the grantee as would be necessary to the enjoyment of the franchise. Could it be claimed, in ¡such a ease, that the easement in the streets would outlast the franchise? Clearly not. Wiiy, then, in this case, where the city’s power to confer the easement only arises from the necessity for the enjoyment of the franchise, is it necessary to infer a power to confer an easement beyond the life of the franchise? Of course, there is this difference between the case just supposed and the conditions which may exist under the statutes here, — that the second grantor, i. e. the city, may impose additional conditions upon the exercise of the franchise, not contained in the original grant of the state, and so may cut off or reduce the time for which the franchise may he actually enjoyed to a time less than the life of the corporation; hut, so far as relates to the maximum tilne of the easement, the supposed case (•learly represents and illustrates limitations upon the combined acts of the state and city. The construction of the statute above stated does not require us to decide that the legislature could not give the city the power to confer on a street-railway company an easement in the streets beyond the life of its franchise. If the power existed, it would be a power in the city to delegate to one company the city’s right to consent to a franchise of a second company, to be created by the state many years thereafter. If such a delegation may be authorized by an act of the legislature, certainly the power to make it cannot be inferred from a mere power to consent to the franchise of the first; company.
The suggestion is made that the words of section 13 of the general railway ad have a greater significance than section 34 of the tram-railwav act, In that the city is therein to consent that the railway company shall construct, maintain, operate, and own its railway, and the argument is that the consent to ownership of rive street railway implies that the easement may extend beyond the life of the franchise to construct and operate. I cannot see that; the insertion of the word “own” changes in any way the meaning of the section. Consent to construct and operate certainly implies consent to ownership in the company, and the franchise to own a street railway, as such, conferred on the company, *882does not endure any longer than its franchise to construct and operate it. After the death of the corporation, it owns nothing. It is the stockholders who own the assets, not by virtue of any franchise conferred by the state, but because, as individuals, they have that faculty and right.'
It remains to inquire what is the life of the franchise conferred by the state upon a street-railway company under the acts of 1861 and 1867. The franchises of a street-railway company are of two lands: First, the kind which every corporation — or, to speak more exactly and properly, its corporators — must have, — the franchise to be a corporation, and to act in its business, and for the purposes of its organization, as a natural person could act; and, second, the franchise to discharge a quasi public function for hire, i. e. to construct, maintain, and operate a street railway for the use of the public, and to collect tolls therefor. Franchises of the second class, which, for. convenience, we may call noncorporate, are defined to be special privileges conferred by the government on individuals, and which do not belong to the citizens of the country generally, as of common right. Bank v. Earle, 13 Pet. 519. Such is the privilege to carry on any business in which the public have an interest, and from which the public may have service upon the payment of the usual fare or toll, as the maintenance of a ferry, a turnpike, or a railroad. People’s Passenger R. Co. v. Memphis City R. Co., 10 Wall. 38. Franchises of this kind may be conferred on an individual, but, as a proper discharge of the quasi public duties generally requires much capital, it is the custom of the legislatures to confer them, directly, only on corporations. In the absence of an express provision in the charter to the contrary, non-corporate franchises conferred on a corporation last as long as the corporation is chartered to live, and no longer. If I comprehend the argument of counsel for the defendants, while they concede that the franchise to be a corporation cannot endure beyond the charter life, they maintain, that when property has been acquired, for the enjoyment of which, a noncorporate franchise is necessary, the franchise becomes property, and is as indestructible and permanent as the property to which it is attached. Much of the argument is based on cases where such franchises and property have been -assigned; and the view seems to be that, because the franchises are assignable, their length of life is independent of that of the corporation. The franchise to be a corporation is personal and cannot be assigned, but there is no objection to assigning-noncorporate franchises. Property is required to enjoy franchises, and, when the property is assigned, the franchise to enjoy it, which is inseparable from it, goes with it to the assignee. Gue v. Tidewater Canal Co., 24 How. 257; Memphis & L. R. Co. v. Railroad Com’rs, 112 U. S. 609, 5 Sup. Ct. Rep. 299; Railway Co. v. Delamore, 114 U. S. 501, 5 Sup. Ct. Rep. 1009; Joy v. Plank-Road Co., 11 Mich. 155; McKee v. Railway Co., 41 Mich. 274, 1 N. W. Rep. 873, and 50 N. W. Rep. 469. But, while the property and franchises are inseparable, that can only be while the franchise *883endures. Though it is assignable, the franchise can only he assigned or enjoyed by the assignee as long as it is in existence. Speaking for the supreme court of Pennsylvania in Railroad Co. v. Casey, 26 Pa. St. 287, Judge Rlaclc said:
“The right to take tolls on a road is an incorporeal hereditament, which may he granted, to a corporation or to an individual, and the grantee has an estate in the franchise. But what an estate? The estate endures forever, if ¿he charter ho perpetual; for years, if it he given for a limited time; and at will, if it be repealable at the pleasure of the legislature.”
This opinion is cited ;is authority by Mr. Justice Miller in his opinion in the case of Greenwood v. Freight Co., 105 U. S. 13, where it was held that, under a reservation clause allowing the legislature to repeal any incorporation act at pleasure, the legislature might repeal the charter of a street-railway company, and destroy its franchise to run its railway in the streets of Boston. Speaking of the effect of the repealing act, -Justice Miller said:
“If the essence of the grant of the charter be to opéralo a street railway and to use the streets of the city for that purpose, it can no longer so use the streets of the city, and no longer exercise the franchise of running a railroad in file oily. In short, whatever power is dependent solely on the grant of ihe charter, and which could not be exercised by unincorporated private persons under the general laws of the state, is abrogated by the repeal of the law which granted these special rights. Personal and real property acquired by the corporation during its lawful existence, rights of contract, or dioses in action so acquired, and which do not, in their nature, depend on the general powers conferred by the charter, are not destroyed by such a repeal; and iho courts may, if the legislature does not provide some special remedy, enforce such rights by the means within their power. The rights of the shareholders of such a corporation to their interest In its property are not annihilated by such a repeal, and there must remain in the courts the power to pro! ect those rights.”
Again:
“The history of the reservation clause in acts of incorporation supports cur proposition, — that whatever right, frandiise, or power in the corporation dept nds for its existence upon the granting' clauses of the charter, is lost by its repeal.”
If this be true, a fortiori, is (lie franchise gone at the expiration of ihe express term for which the charter rights were granted?
It should, be said that if is a mooted question whether, when a legislature exercises its right to repeal the charter of a corporation under ihe usual reservation clause, the repeal terminates those franchises of the corpora (ion which are not corporate, and which are necessary to the enjoyment of properly acquired by the corporation during its lawful existence. The court of appeals of New York, in the case of People v. O’Brien, 111 N. Y. 1, 18 N. E. Rep. 692, has held that such a repeal does not take away the franchise to maintain and construct a street railway on a street of New York, the perpetual easement for which had been obtained from the city. It seems difficult to reconcile this case with Greenwood v. Freight Co., supra, or with Railroad Co. v. Casey, supra. Upon this point, it is probable that the law of Michigan is more in accord with that of New York than with that of the cases just referred to, for in Detroit v. Detroit & H. P. R. Co., *88443 Mich. 140, 5 N. W. Rep. 275, the supreme court of Michigan decided that the power to alter, amend, or i*epeal the charter of a plank-road company did not permit the legislature to pass an act compelling the plank-road company to remove its tollgate beyond the municipal limits of Detroit, and give up the tolls of 2-1,-miles of its road, on the ground that the franchise to collect tolls for the use of the road was property, and therefore the act deprived the plank-road company of its property. Rut such a conclusion as that in People v. O’Brien, or that in Detroit v. Detroit & H. P. R. Co., has no bearing on the point we are discussing. It is only, in effect, a holding that the power of repeal reserved does not enable the legislature to reduce or destroy the value of the property of the corporation by arbitrarily taking away from its creditors and stockholders, during the charter term,' the right to enjoy it in -the way provided in the charter. But property acquired by a corporation is purchased for its enjoyment only during the charter life, and the necessary expiration of the franchise therein conferred is a fact entering into every investment of capital made by it, just as the improvements made by a lessee or life tenant must be made with the termination of his estate in view. The analogy is not quite accurate, because the lessee or life tenant loses his improvements, while the corporation only loses the value giving franchise, but its stockholders retain the rest of its property. Take the case of Detroit v. Detroit & H. P. R. Co., supra. The corporation was created for 60 years, with the right to construct a plank road and take tolls. The act of the legislature, the validity of which was attacked, was passed at the end of 30 years. Certainly, the supreme court of Michigan would not have held that when the 60 years of its life had expired the company might sell the road (if it had acquired it in fee) to another, and confer on that other the franchise to collect tolls. Yet this is the result involved in the contention of counsel for the defendants, that the attaching of franchises to property gives the former as much permanence as the latter.
The point under discussion is expressly decided by the supreme court of the United States in the case of Turnpike Co. v. Illinois, 96 U. S. 63. In that case a turnpike company was created a body corporate, to continue for 25 years, with power to construct and maintain a certain turnpike, erect the tcllgates, and collect tolls. The state reserved the right to purchase the' road at the expiration of the charter by paying the corporation the original cost of construction, but the road, and all its appendages, were to remain in possession of the company, subject to the rights and restrictions contained in the charter, until such time as the state should refund the cost. By a supplemental act passed in 1861, the company was authorized to extend its road, and, in consideration of its keeping in repair a certain bridge and dyke, to use them as part of the road, erect tollgates thereon, and collect tolls. When the 25 years, the term of the charter, had expired, in 1869, the legislature passed an act granting the city of East St.' Louis the *885exclusive control of the street upon the dyke. The act of 18(51) was attacked, as impairing- contract obligations. It was held that the franchise to collect tolls on the bridge and dyke, conferred by the supplemental act of 1861 was separate and distinct from that authorizing the collodion of them on the original road, with its provision for continuance beyond the corporate life, and that the second franchise did not extend beyond the term of years for which ihe corporation had been created. Said Mr. Justice Bradley:
“No term was expressed for the enjoyment of this privilege, and no conditions were imposed for resuming or revolting it on the part of the state. It cannot he presumed that it was intended to he a perpetual grant, for the company itself had hut a limited period of existence. At common law, a grant to a natural person without words of inheritance creates only an estate for the life of the grantee, for he can hold the property no longer than he himself exists. By analogy to this, a grant to a corporation aggregate, limited as to the duration of its existence, without words of perpetuity being annexed to the grant, would only create an estate for the life of the corporation. In the present case the turnpike company was created to continue a body corporate only for the term of twenty-five years from 1he date of its charter; and although, by necessary implication, a further continuance, with the special faculty of holding and using the turnpike authorized by the act until redeemed by the state, is given to it for that purpose, yet it is only by implication, arising from ihe necessity of the case, and therefore cannot he extended to other purposes and objects. Grants of franchises and special privileges are always to be construed most strongly against the donee, and in favor of the public.”
The learned justice then said that if the company had constructed the bridge, and acquired a fee in the dyke or road, the case would have had a different aspect, for then the question would have been whether the state could take the property back without just compensation. These last remarks refer to the fact that the state had resumed possession of the bridge and road. If the turnpike company had built the bridge, and bought the land, and built the road, its property in them would not, of course, be destroyed by the determination of the franchise, and the public could not use them without paying just compensation. The franchise to collect, tolls on them, however, would not have continued, and there is nothing in the language of the court which would justify such an inference.
If may therefore be assumed, with entire confidence, that when the state cf Michigan granted, by virtue of its laws, to the Detroit, City Railway Oompauy, the franchise to construct and operate a street railway, it was limited to the life of the company, no matter to whom the franchise might be thereafter assigned, or to what property it might become attached. It necessarily follows that the power of the city to consent to the exercise of the franchise conferred upon the railway company was also limited in its duration to the life of the corporation. Either the limitation stated exists, or the power of the city is unlimited, and it may create in the streets, by virtue of the power to grant an easement, implied from these statutes, an estate in perpetuity. RTo other limitation can be found in the act than the life of the com*886pany to whom tbe consent is to be given. It is suggested tbat the present grant, the validity of which is contested, was only 30 years, and as the city, unquestionably, had the right to confer a grant of that duration on one company, it might upon another. This ignores altogether the logical ground upon which the limitation must be implied. The 30 years mentioned in the statute can have no effect to limit the duration of the consent or easement which the city confers, except by reason of the fact ihat this is the time beyond which the life of the franchise and the corporation cannot extend. This shows that the real limitation is not the 30 years, but it is the life of the corporation. It is suggested that there is some time between the life of the corporation and a perpetual grant, to be defined by the courts as a reasonable time within which the grant can endure. I do not know any mode by which such a limit can be fixed. In many of the states, grants made are perpetual, and this where there are no words of perpetuity, but merely words without limitation. In view of the fact which appears in Booth on Railways, (section 17,) that, in some 10 or 12 states, grants of this kind have been made and sustained, which are perpetual, it cannot be said that a perpetual grant would be so unreasonable that the court might hold it void, if the statute cannot be construed definitely to fix the duration of a grant less than one in perpetuity. The attempt of the supreme court of Iowa to determine what would be reasonable time for the duration of an exclusive grant in the streets to a street railway, in Des Moines St. Ry. Co. v. Des Moines R. G. St. Ry. Co., 73 Iowa, 513, 33 N. W. Rep. 610, and 35 N. W. Rep. 602, did not meet the approval of Justice Jackson in Grand Rapids E. L. & P. Co. v. Grand Rapids E. E. L. & F. G. Co., 33 Fed. Rep. 659. See, also, Mr. Justice Brown’s opinion in Saginaw Gas-Light Co. v. Saginaw, 28 Fed. Rep. 529, and Richmond Gas-Light Co. v. Middleton, 59 N. Y. 228. As between a construction which will place a limitation on the grant, and one which will give rise to a perpetuity, it is clear that it is the duty of the court, in favor of the public, to impose the limitation. It is true that what we are considering here is the power to make the grant, and not the grant itself. But the same rule applies in the construction of statutes conferring powers upon municipal corporations to make such grants as in the construction of the grants themselves. But even suppose that, where there was no limitation, the courts might fix a reasonable limitation. Why is it necessary for them to do so where there is a plainly-implied limitation in this statute? Certainly, if that limitation is not unreasonable, why seek another? It does not appear that it is unreasonable.
Reference is made, to show the necessity for a longer grant than the life of the corporation, to those sections of the street-railway acts which give the company power, with the consent of the city, to build new routes, and to extend its old lines. It is said that it would seriously interfere with the probability that such new routes would be built in the latter years of the corporation’s life *887if the estate of the railway company in the streets were limited to its life. It does not seem to me that this result should prevent what seems to be a reasonable construction of the statute. An express provision of law that the city council might confer an easement in the streets for 20 years, but that such easement should not be extended during its continuance, would hardly seem unreasonable. If one railway company will not build new routes and make extensions, the city would be able generally to secure the building of the new routes by grants to new corporations, and perhaps even to accomplish the same thing with reference to extensions. Neither the law nor public policy requires that one railway company shall furnish all the railway facilities in tint city to the public. Nor does the provision for mortgaging the franchises and property of the company, with power in the purchasing company to use the property and exercise the franchises as the old company would have done, Indicate a purpose on the part of the legislature to lengthen the time within which easements, in the st reets can be granted. The new company is to exercise exactly the same rights in the streets that the old company did under the statute and no more.
It by no means follows that, because under its general corporate powers the street-railway company might have the authority to receive an estate in the streets beyond its own life, the city has the power to confer such an estate. The usefulness of such a franchise to the company need not be denied. Its right to bold it, need not be inquired into. The guide which the court must follow in construing the powers of the city is the interest of the public, and not the company, and only in so far as it is necessary to the exercise of the franchise can the power of the city be inferred to grant the easement. The cases which have been referred to as establishing the principle that the life of the corporation cannot interfere with its receiving an estate to endure thereafter have no application to the case at bar. The power of the city, or the owner of the estate to be granted, to convey, was in none of the cases the question. Thus, in ■(lie case of State v. Laclede Gaslight Co., 102 Mo. 472, 14 S. W. Rep. 974, and 15 S. W. Rep. 383. (lie question was whether a city ordinance granting to the Laclede Gaslight Company, its successors and assigns, the privilege of furnishing gas to the city and private consumers for a named period, was void because the term extended beyond the period of the existence of the company’s charter. The ordinance provided that it might transfer all its rights, privileges, and franchises to any organized gas company of the state, which would, within 20 days after (he transfer, die its written acceptance of the ordinance, and give bond to perform all the agreements required of the original company. The power of the city to make the contract was conferred in the charter to the St. Louis Gas Company by section 13 of the act of February 31, 1839, and is stated in City of St. Louis v. St. Louis Gaslight Co., 70 Mo. 98. The provision was that the corporation of the city of St. Louis and the directors of the St. Louis Gas Company might contract for, and *888make regulations relating to, the lighting of the city with gas, in such manner as should be agreed upon, and they might make such contracts relating to the lighting of the city as might be beneficial to them and the public, and in the case last cited the court say:
•‘This section is hroad and comprehensive in its terms, and authorized both plaintiffs and defendant’s board of directors to contract with reference to the business of the company without limitation, they being left to the determination of the question whether such contract would be beneficial to Themselves and the public.”
There was no question of the power of the city in People v. O’Brien, 111 N. Y. 1, 18 N. E. Rep. 692. Reference is also made to New Orleans City & L. R. Co. v. New Orleans, 148 U. S. 192, 12 Sup. Ct. Rep. 406, where the question was one of taxation. It appears in the recital of facts, as reported by the supreme court, that defendant below had acquired all the real and personal property, right of way, and franchise for the privilege of running street cars, from another street-railway company, whose charter had expired; and it is said that this appeared to be no objection to the supreme court of the United States, and did not call for comment. In the report of the same case In 40 La. Ann. 587, 4 South. Rep. 512, this fact does not appear in the statement, and it is obvious, therefore, that no question was raised in either court on the point. Nor is it surprising, in view of the holding in Brown v. Duplessis, 14 La. Ann. 842, that the city, under its general power of regulating the use of the streets, might sell an easement in them for a.' railway, to an individual, for 20 years, without his having secured a state franchise. The case shows that in Louisiana the city can grant the franchise without the state’s acting at all; so that, of course, there is no necessary connection between the life of the corporation created by the state, and a franchise which the city has a right to confer on an individual without limitation. This fully explains the rulings of the United States supreme court in New Orleans City & L. R. Co. v. New Orleans, supra, and Railroad Co. v. Delamore, 114 U. S. 501, 5 Sup. Ct. Rep. 1009, if indeed, they involve the point claimed by defendants’ counsel, which is by no means clear, because there is no discussion or consideration of it in either case.
Another argument made against limiting the city’s power of consent to the life of the corporation is the practice which is said to have prevailed all over Michigan, of making grants in the streets beyond the life of the corporation grantee. Sixteen instances have been submitted. This is not a large number, considering the number of such corporations of the kind in question which there must be in the state. Of the grants submitted, half were made in 1890, or since, and the rest were scattered along between 1880 and 1890. While the practical construction of a doubtful statute, by those who are required to construe it in order to execute it, is often persuasive with the courts, such construction, to he controlling, must have been uniform, long continued, and generally acquiesced in. Neither requirement is complied with here. Some *889councils seem to have thought that, the legal limit on grants was 30 years, and some have made grants perpetual. The great weakness of the argument on this ground, however, is in the fact that in no instance submitted has the first grant expired. Until such expiration the question of the validity of the extension would not be raised, and there could hardly be said to be acquiescence therein by the public, or others interested to question it.
It is insisted that the necessary result of this limitation upon the right of the city to consent to the construction and maintenance of a street railway is that the easement conveyed by the city would end upon the premature dissolution of the corporation under the, repealing clause, or by judicial forfeiture, as well as upon its l death by normal expiration of the charter term. Even if this result does follow, it is not, the raluetio ad absurdum. Whether this is the result or not depends on the effect to be given to the repealing clause, or the judicial forfeiture. If either can take away the property rights in a franchise, then the question would still remain, whether the easement of the railway company might not endure for the normal life of the franchise, inasmuch as it was not granted by the state, but by the city, for that normal life. Whatever the conclusion upon this point, it would not, in any way, as it seems to me, show that the power of the city is not to be limited by the normal life of the franchise and the corporation. Under the decision in Detroit v. Detroit & H. P. R. Co., 43 Mich. 140, 5 N. W. Rep. 275, it is probable that premature dissolution would not prematurely destroy the noncorporate franchises, when attached to the easement conferred by the city, and that they might both endure until the normal expiration of the franchise.
Another argument against the conclusion arrived at, as to the city’s power, is the supposed anomaly that the grant of 1879 to the City Railway Company for an extension of its easement in the streets beyond its life should be invalid, when, if the stockholders of the City Railway Company had caused a transfer of its property and franchises to a new company, and then had procured the grant of 1879 to the new company, its validity -would have been beyond dispute. The anomaly, if there be one, arises from the law which courts are not permitted to ignore, that one corporation is a different entity from another, and from the limitation upon the lives of corporations, which seems to be the peculiar policy of the state of Michigan. Section 10, art. 15, of the state constitution provides that no corporation, except for municipal purposes, or for the construction of railroads, plank roads,' and canals, shall be created for a longer period than 30 years. It has been the subject of some argument at the bar as to whether street railways come within the inhibition, or within its exception. I am inclined to think, considering the fact that street railways were not known at the time the constitution was adopted, that they are not properly included within the exception, and that they are within the inhibition of the constitutional provision. This view is borne out by the construction which the legislature has put upon this section in its *890provision for the corporate life of street railways. The street railways, as has -already been stated, were organized first under the tram-railway act, which provided for locomotion by horse power only, and they were limited in life to 30 years. Bailroads, however, — that is, commercial railroads, — plank-road corporations, and canals have not been limited in duration by the legislature. Street-railway corporations, organized under both the tram-railway act and the general railway law, have always been limited to 30 years. This would seem to be a construction by the legislature of this section, and a recognition that the street railway was not properly a railroad, within the view of the framers of the constitution. But it is really immaterial, for the discussion here, whether it is or not. The life of street-railway companies is limited by the incorporating act to 30 years, and it is to be inferred that the reason for the limitation is the same as that which induced the constitutional convention, and the people who adopted its work, to impose a limitation on corporate life in the constitution. Now, the reason for this constitutional limitation has been explained by the supi'eme court of Michigan 'in the case of Agricultural Soc. v. Houseman, 81 Mich. 610, 46 N. W. Rep. 15, where the court said:
‘•The evident intent of this section was to prevent the perpetuation of corporate power and corporate life, so as to place it practically beyond the reach of the people or the legislature. It was intended to apply to corporations of a private character, organized for profit and the accumulation of wealth, and not to those which are public in their character, and designed solely for the purposes of education and improvement.”
In the case of Mason v. Perkins, 73 Mich. 303, 41 N. W. Rep. 426, where the question was as to the validity of an act of the legislature of Michigan authorizing- mining and manufacturing companies to renew their corporate existence for 30 years, the court, in an opinion denying the power of the legislature to pass such an act, said:
“Is not such a mandate a direct and positive limitation on the power of the legislature to extend the time, or renew the corporate existence, beyond that term? What consequences are expected to follow upon the expiration of such limitation? Naturally, the corporation becomes dissolved, and ineapahlo longer of exercising corporate functions in pursuing and carrying on its business. Its business is to be closed out, its obligation paid, and the assets distributed among its stockholders. * * * The design of the framers of the constitution was to put all purely private corporations on the same footing, and to fix a limit of time, beyond which they should not continue to exist.”
It is sufficiently apparent from this, and from the constitutional limitation itself, that the limitation upon the corporate life was not a mere formality, but it was intended to interfere with the perpetuation of corporate wealth and power. In the light of this state policy, it would hardly he proper for a court to be swayed from a conclusion as to the meaning of a statute by the claim that it involves an anomaly, when the anomaly has no existence, except in the view that a corporation may in fact perpetuate its wealth and franchises, and remain identically the same entity, no matter how many different mimes it bears, or bow many formal convey-*891anees of property and franchises are necessary to continue its existence. I am of opinion, for the reasons given, that it was not within the power of the common council of Detroit, on November 14, 1879, to confer upon the Detroit City Railway the right to occupy the streets with a railway 16 years beyond its corporate life.
The discussion, thus far, has related to those grants in the streets which were made by the city to the Detroit City Railway. All of them must be held to expire on the 9th of May, 1893. But the grants to the Detroit, & Grand Trunk Junction Railway Company, and to the Central Market, Cass Avenue & Third Street-Railway' Company, even if the ordinance of 1879 had not been passed, would not have expired until 1903 and 1905, respectively. When the ordinance of 1879 was passed, those grants were owned by the Congress & .Baker Street Railway Company and. the Cass Avenue Street-Railway Company, whose charters did not expire until 1905 and 1907, respectively. The extension of 1879, with respect to these grants, would be valid until those dates, if the owners chose to rely on the ordinance as binding on the city pro tanto. Whether, therefore, the ordinance of 1879 is to be wholly' annulled, or to be given effect, as far as may be, the grants referred to do not terminate May 9, 1893. It cannot affect this result |that the franchise and easement lawfully enduring until 1905 and 1907 were, after they came into existence, held for a time by the Detroit City Railway Company. Whether that company had the ¡power 1o take such property, and enjoy it, or not, its actual ownership and enjoyment of it could not forfeit and destroy' the existence and continuance of the inseparable easement and franchise during the life of the first grantee of the franchise. ' The Detroit Citizens’ Street-Railway Company is in possession of these easements and franchises, and we are not here to determine the legality of tin mode by which it acquired title, in the absence of the original grantees of those easements and franchises, who, so far as appears, fully acquiesce in its ownership of them: I say this much to show that we do not need now to consider, and do not decide, the question whether the Detroit City Railway had the statutory capacity to receive from another company that, company’s franchise and easement, enduring beyond the life of the Detroit City Railway'. With, respect (o the Congress & Baker Street grant and the Cass Avenue grant, the relief prayed for by the complainant must be denied.
I have reached the conclusion above stated as to the meaning of the street-railway laws of Michigan only after giving this cast* the study and investigation which the large amount involved in the issue, and my want of familiarity with the Michigan law, have necessarily' required. The fact that my Brother Swan, with his legal acumen, long training, and intimate knowledge of the Michigan law, differs with me, gives me much concern, lest I have reached a wrong result. Nevertheless I cannot reconcile any other result to the rules of construction which it seems to me must govern *892in the case; and it is my duty, therefore, to adhere to the position as stated.
2. It is' contended on behalf of the defendants that, even if the ordinance of 1.879 is invalid, a court of equity, will not assist the city, by affirmative relief, to avoid or annul it, or to restore the streets to its possession, which it parted with in performance of the invalid contract.
In St. Louis R. Co. v. Terre Haute R. Co., 145 U. S. 393, 12 Sup. Ct. Rep. 953, the supreme court decided that when a corporation appeals to a court of equity to rescind a contract which is ultra vires, and to be restored to rights parted with under it, the court should refuse to grant any relief, because both parties to the contract made in violation of law are in pari delicto, and should be left where the court finds them. The cases cited, and others like it, do not, however, apply to the case at bar. The defendant is now occupying the streets of Detroit. It has no right to be there, except by a lawful grant of the city. The city council, in its legislative capacity, passed the ordinance of March 29, 1892, fixing the time beyond which the company could not remain in the streets. The question here is whether the ordinance of 1892 is valid, as an exercise of the council’s legislative power over the streets.- We have found that the ordinance purporting to make a grant beyond May 9, 1893, wa-s invalid. It was therefore within the power’ of the city council to pass the ordinance of March 29, 1892, and by virtue of its terms the company will unlawfully occupy the streets after May 9, 1893. The city does not need to have the ordinance of 1879 rescinded by a court of equity. The city has already rescinded it by the ordinance of 1892. The continuance of the street-railway tracks in the streets, without the authority of the city, will become a public nuisance, which the city may ask a court of equity to remove by the power of injunction. Bay Co. v. Bradley, 39 Mich. 163. The case of the city is different from that of a private corporation. The city council, for the time being, is the trustee, in control of the streets for the benefit of the public; and, although former trastees may have attempted to do that which they had no power to do, the public cannot be prevented from having asserted in its favor the ordinary equitable remedies to maintain its rights in the streets.
3. The answers plead that the city is estopped in this case to maintain that the extension clauses of the ordinance of 1879 are invalid, because in a previous litigation between the city and the Detroit City Eailway Company the validity of the ordinance in question was involved and a judgment was rendered against the city on that issue by the supreme court of the state of Michigan. The litigation referred to was an attempt by the city to collect taxes from the Detroit City Eailway Company beyond the limits fixed in the ordinance of 1879 and the ordinance of 1887. The street-railway company relied on the contract provisions of the ordinance with reference to the amount of taxes which the city should collect, and the city contended that those clauses did not, *893and could not, limit its riglit to impose Í axes under the laws of the state. The supreme court held that it was within the power of the city to stipulate what taxes the street railway should pay for the enjoyment of its easement in the streets, and to bind itself as by a contract. The validity of that clause in the ordinance of 1879, which extended the privileges and obligations of the ordinance of 18(52 beyond May 9, 1898, was not, however, involved in the case. As against the city, the ordinance would be binding until May 9, 1893, and it would not lie in its mouth to say that, the taxation clauses were invalidated because it had not the power to do all it. stipulated to do with reference to the extension of the* easement beyond 1893. Had the city been seeking to enforce some of he stipulations contained in the ordinance against the railway company, it would doubtless have been a good defense for the company to have set up the invalidity of the extension beyond May 9, 1893, but such invalidity, if waived, or not questioned, by the company, would furnish no ground for the city to disregard its other obligations under the contract. It ivas not necessary, therefore, for the. supreme court, in deciding the case inferred to, of City of Detroit v. Detroit City Ry. Co., 76 Mich. 421, 43 N. W. Rep. 447, to pass upon, or consider, the validity of that clause of the ordinance of 1879 which is here in question; and its judgment in that case cannot, by any possibility, be res adjudicata here. Jacobson v. Miller, 41 Mich. 90, 1 N. W. Rep. 1013; Cromwell v. County of Sac, 94 U. S. 351.
4, We come now to a defense which certainly appeals to a chancellor. The answer sets out with much particularity the extensions and the expenditures which the Detroit City Eailway made upon the faith that the grant, of the easement in the streets beyond its corporate life, until 1909, was valid. It appears from a comparison of the ordinance of 1862 with that of 1879 that the Detroit City Eailway assumed much heavier obligations under the new ordinance than it had under the old, with respect to paving between tracks and paying taxes. Until within the last two years, no one, on the part of the city, has questioned the validity of the extension which we have found to be invalid. Large sums of money have been expended on the faith of it. Obligations have been enforced by the city against the street-railway company, which derived their, binding character onfy from the ordinance of 1879. Were the city an individual, its conduct, in now seeking to escape?, for want of power, its obligations solemnly entered into, and for more iban a decade quietly acquiesced in, might justly be? said to be wanting in good faith. Were the casé one in which money had been given to the city, or where work had been done upon property which the city held, it might be possible for the court to give the defendant company relief, by requiring the city to disgorge that which it had illegally taken, by giving a money judgment against it, for money and property ha,d and received. Hitchcock v. Galveston, 96 U. S. 341. But it is impossible, in this case, to apply such a remedy. The investments of the street-rail*894way company were not given to tie city. They were investments of private funds in private property, for private purposes, to sub-serve the public interest, on the faith of the supposed permanence of the investment. Those who made the investment knew, or ought to have known, the statutory powers under which the city council acted, and if I am right in the conclusions already stated with reference to those powers, ought, in the necessary theory of the law, to have known that they were investing on the faith of a grant which would last only to May 9, 1893. Where full knowledge of the powers of a corporation are had by the person dealing with it, he cannot plead estoppel by reason of a mistake of law, to avoid the claim of ultra vires. This is especially true in cases where the corporation is a municipal corporation, and is exercising powers in trust for the public. Rens v. City of Grand Rapids, 73 Mich. 237, 247, 41 N. W. Rep. 263; Bogart v. Lamotte Tp., 79 Mich. 294, 44 N. W. Rep. 612; Spitzer v. Village of Blanchard, 82 Mich. 234, 46 N. W. Rep. 400. I am of the opinion, therefore, that the plea of estoppel is no defense in favor of the Detroit City Railway, upon whom, as we have found, the city council had no power to confer the grant to occupy the streets beyond May 9, 1893.
In the consideration of the plea of estoppel, however, a different question from the one just considered is presented by the transfer, in December, 1890, of all the property and franchises of the Detroit City Railway Company to the Detroit Street-Railway Company, and later by the Detroit Street-Railway Company to the Detroit Citizens’ Street-Railway Company. The two latter companies had lives and franchises from the state, enduring until 1920, and there was no want of power in the city or city council to make a grant to either of them until 1909, like that now claimed by them under the ordinance of 1879. If the city, after these two companies have had possession of the streets, has recognized the ordinance of 1879 as valid, by enforcing obligations against, them under it, which could not be enforced under the ordinance of 1862, and which these companies discharged on the faith of the 1909 extension, and in doing so expended much money, the question presented is whether the city is not estopped, as against them, to deny that it has confirmed in pais the void grant to the Detroit City Railway Company, and made it a valid grant directly to them. The averments of the answer upon this point are as follows:
“That, under tlie provisions of the various ordinances and grants heretofore referred to, the several street railways to which such grants were made were required to, and did, pave; repave, and repair, and keep clean, portions of the streets between and adjacent to their tracks, and in so doing expended large sums of money for permanent improvements on the streets so occupied by them. That, during the years 3890 and 1891, some of said companies, their successors and assigns, were required to alter the grading of the streets, and to relay, at great expense and labor, many miles of the track, and since January 3, 1889, have constructed many miles of track on new lines, and extensions of old ones,' all of which they did with the full knowledge and understanding of the city of Detroit, and solely by reason of its admission and agreement that the rights, privileges, extensions of time, contained and made in and by the ordinance aforesaid, adopted November 14, 1879, were *895valid and binding and enforceable on said city, as well as on said company. That in the year 1890 the said city of Detroit repaved Jefferson avenue from Mt. Elliott avenue to Woodward a,venue, and the said Detroit City Railway Company was thereby required to, and did, rebuild its entire tract on said Jefferson avenue, and change the grade thereof, and did pave between its tracks, making- a permanent improvement, which would last for many years. That during- the year 1891 many other extensive permanent improvements were made by said Detroit City Railway Company, its successors and assigns, involving the outlay of large sums of money, solely by reason of the understanding- between the said city and 1lie said company, and of the admission and agreement of said city of Detroit that the rights of said company, their successors and assigns, under the ordinance of November 14, 1879, extended until November 14, 1909. And this defendant avers that the said city of Detroit, by reason of the matters herein set forth, is estopped from claiming that said ordinance of November 14, 1879, is invalid, and from taking anj' advantage of the invalidity of said ordinance, should this court, for any reason, in any proceeding before it, hold the same to be void and ineffectual.”
My impression is that upon tlie. foregoing averments, thongli they are not very clear in distinguishing between the acts of the new and of the old company, the question suggested above is presented. The decision of the question is by no means free from difficulty. Because of the then more important questions, it was not argued at the bar. As it has, in my view of the other questions, assumed an importance, in deciding the case, not before given to it by counsel, I do not think it should he disposed of without full argument. More than this, the magnitude of the interest of both parties to this cause is such that all doubt or ambiguity in regard to the exact facls upon the point should he removed by amendment. The facts can hardly be the subject of much dispute between the parties, because many or all of them must he capable of record proof, and it is hoped the parties can agree upon them. The order of the court, therefore, will he for a further argument of the point stated, with leave to the defendants, within 10 days from the filing of this opinion, to amend their answers to more distinctly disclose the facts upon the point. If complainant cannot accept defendants’ statement of facts in the amendment, a replication may be filed, and evidence taken, as in other cases.
