MR. JUSTICE DAY, after making the foregoing statement, delivered the opinion of the court.
In the case of the New Orleans Gas Company v. Louisiana Light Company, 115 U.S. 650, it was held that the complainant, by reason of the franchises granted and agreements made, as fully set forth in that case, had acquired the exclusive right to supply gas to the city of New Orleans and its inhabitants through pipes and mains laid in the streets.
It is the contention of the plaintiff in error that, having acquired the franchise and availed itself of the right to locate its pipes under the streets of the city, it has thereby acquired a property right which cannot be taken from it by a shifting of some of its mains and pipes from their location to accommodate the drainage system, without compensation for the cost of such changes. It is not contended that the gas company has acquired such a property right as will prevent the Drainage Commission, in the exercise of the police power granted to it by the State, from removing the pipes so as to make room for its work, but it is insisted that this can only be done upon terms of compensation for the cost of removal. This contention requires an examination of the extent and nature of the rights conferred in the grant to the gas company. The exclusive privilege which was sustained by this court in the case of the New Orleans Gas Co. v. Louisiana Light Co., supra, was the right to supply the city and its inhabitants with gas for the term granted. There was nothing in the grant of the privilege which gave the company the right to any particular location in the streets; it had the right to use the streets, or such of them as it might require in the prosecution of its business, but in the original grant to the New Orleans Gas Light and Banking Company the pipes were to be laid in the public ways and streets, "having due regard to the public convenience." And in the grant to the Crescent City Gas Light Company the pipes were to be "laid in such manner as to produce the least inconvenience to the city or its inhabitants." In the very terms of the grant there is a recognition that the use of the streets by the gas company was to be in such manner as to least inconvenience the city in such use thereof. Except that the privilege was conferred to use the streets in laying the pipes in some places thereunder, there was nothing in the terms of the grant to indicate the intention of the State to give up its control of the public streets, certainly not so far as such power might be required by proper regulations to control their use for legitimate purposes connected with the public health and safety. In the case above cited, in which the exclusive right to supply gas was sustained, there was a distinct recognition that the privilege granted was subject to proper regulations in the interest of the public health, morals and safety. Upon this subject Mr. Justice Harlan, speaking for the court, said (115 U.S. 671):
"With reference to the contract in this case, it may be said that it is not, in any legal sense, to the prejudice of the public health or the public safety. It is none the less a contract because the manufacture and distribution of gas, when not subjected to proper supervision, may possibly work injury to the public; for the grant of exclusive privileges to the plaintiff does not restrict the power of the State, or of the municipal government of New Orleans acting under authority for that purpose, to establish and enforce regulations which are not inconsistent with the essential rights granted by plaintiff's charter, which may be necessary for the protection of the public against injury whether arising from the want of due care in the conduct of its business, or from any improper use of the streets in laying gas pipes, or from the failure of the grantee to furnish gas of the required quality and amount. The constitutional prohibition upon state laws impairing the obligation of contracts does not restrict the power of the State to protect the public health, the public morals, or the public safety, as the one or the other may be involved in the execution of such contracts. Rights and privileges arising from contracts with a State are subject to regulations for the protection of the public health, the public morals, and the public safety, in the same sense, and to the same extent, as are all contracts and all property, whether owned by natural persons or corporations."
The drainage of a city in the interest of the public health and welfare is one of the most important purposes for which the police power can be exercised. The Drainage Commission, in carrying out this important work, it has been held by the Supreme Court of the State, is engaged in the execution of the police power of the State. State v. Flower, 49 La. Ann. 1199, 1203.
It is admitted that in the exercise of this power there has been no more interference with the property of the gas company than has been necessary to the carrying out of the drainage plan. There is no showing that the value of the property of the gas company has been depreciated nor that it has suffered any deprivation further than the expense which was rendered necessary by the changing of the location of the pipes to accommodate the work of the Drainage Commission. The police power, in so far as its exercise is essential to the health of the community, it has been held cannot be contracted away. N.Y. & N.E. Railroad Co. v. Bristol, 151 U.S. 556, 567; Butchers' Union Co. v. Crescent City Co., 111 U.S. 746, 751; Stone v. Mississippi, 101 U.S. 814, 816. In a large city like New Orleans, situated as it is, and the entrepot of an extensive commerce coming from many foreign countries, it is of the highest importance that the public health shall be safeguarded by all proper means. It would be unreasonable to suppose that in the grant to the gas company of the right to use the streets in the laying of its pipes it was ever intended to surrender or impair the public right to discharge the duty of conserving the public health. The gas company did not acquire any specific location in the streets; it was content with the general right to use them, and when it located its pipes it was at the risk that they might be, at some future time, disturbed, when the State might require for a necessary public use that changes in location be made.
This right of control seems to be conceded by the learned counsel for the plaintiff in error, in so far as it relates to the right to regulate the use of the surface of the streets, and it is recognized that the users of such surface may be required to adapt themselves to regulations made in the exercise of the police power. We see no reason why the same principle should not apply to the sub-surface of the streets, which, no less than the surface, is primarily under public control. The need of occupation of the soil beneath the streets in cities is constantly increasing, for the supply of water and light and the construction of systems of sewerage and drainage, and every reason of public policy requires that grants of rights in such sub-surface shall be held subject to such reasonable regulation as the public health and safety may require. There is nothing in the grant to the gas company, even if it could legally be done, undertaking to limit the right of the State to establish a system of drainage in the streets. We think whatever right the gas company acquired was subject in so far as the location of its pipes was concerned, to such future regulations as might be required in the interest of the public health and welfare. These views are amply sustained by the authorities. National Water Works Co. v. City of Kansas, 28 Fed. Rep. 921, in which the opinion was delivered by Mr. Justice Brewer, then Circuit Judge; Gas Light & Coke Co. v. Columbus, 50 Ohio St. 65; Jamaica Pond Aqueduct Co. v. Brookline, 121 Massachusetts, 5; In re Deering, 93 N.Y. 361; Chicago, Burlington &c. R.R. Co. v. Chicago, 166 U.S. 226, 254. In the latter case it was held that uncompensated obedience to a regulation enacted for the public safety under the police power of the State was not taking property without due compensation. In our view, that is all there is to this case. The gas company, by its grant from the city, acquired no exclusive right to the location of its pipes in the streets, as chosen by it, under a general grant of authority to use the streets. The city made no contract that the gas company should not be disturbed in the location chosen. In the exercise of the police power of the State, for a purpose highly necessary in the promotion of the public health, it has become necessary to change the location of the pipes of the gas company so as to accommodate them to the new public work. In complying with this requirement at its own expense none of the property of the gas company has been taken, and the injury sustained is damnum absque injuria.
We find no error in the judgment of the Supreme Court of Louisiana and the same is
