аfter stating the case as above, delivered the opinion of the court.
Intercourse between the ¡States by the telegraph is interstate commerce.
Telegraph Co.
v.
Texas,
The other division of the court, on the other hand, expressed the view that “the legislature intended its action to be coextеnsive with its authority to act, and that the statute should be given the broadest possible application,” and held to cover state and interstate messages and “to forbid a limitation of liability” for negligence and “to make void the stipulation contained in the contract.” The power of the legislature to pass it was asserted, and that it did not burden interstate commerce. “The contract,” it was said, “was made in the State, is single, involves in its performance service of defendant within and without this State for a single charge.” The service was not performed, and for the breach of the common law and contract duty the milling company has brоught suit, it was said, and that the telegraph company seeks to avoid liability by the stipulation on the back of the message. To this defense it was answered:
“By the law of the State, the stipulation is of no force or effect. The court so declared. It is contended here *415 that in so doing the court was in error. It will be well to havе in mind the effect of the statute as it was applied by the trial court. Undoubtedly, it was the application of a local law to the contract. But the local law does not attempt to state, measure or define any duty of defendant, or to establish, define or fix the consequences of its miscarriage.’ The liability , оf defendant is established without reference to the statute. It is when it asks to be discharged therefrom, by giving effect to the stipulation, that the local law becomes, if at all, effective. These considerations answer those objections which are based upon, the notion that the local law has been given extrаterritorial effect, and they require, also, that this case and Western Union Tel. Co. v. Pendleton,122 U. S. 347 , shall be distinguished.”
Western Union Tel. Co.
v.
Pendleton,
We have seen that one division of the Supreme Court of the State was of the view that if the prohibition rested on the common law its validity could not be questioned. We cannot concede’ such effect to the common law and deny it to a statute. Both aré rules of conduct-proceed *417 ing from the supreme power of the State. That one is unwritten and the other writtén can make no difference in-their validity or effect. The common law did not become a part of the laws of the States of its own vigor. It has been adopted by constitutional provision, by statute or deсision, and, we may say in passing, is not the same in all particulars in all the States. But however adopted, it expresses the policy of the State for the time being only and is subject to change by the power that adopted it. How then can it have an efficacy that the statute changing it does not possess?
It is to the laws, whеther part of the common law or found in the statutes of the State, that we look for the validity and extent of a contract between persons. They constitute its obligation. How far this principle is limited by the commerce clause of the Constitution of. the United States may be illustrated by several cases cognate tо the one at bar.
In
Chicago &c. Railway
v.
Solan,
*418 “Railroad corporations, like all other corporations and persons, doing business within .the territorial jurisdiction of a State, are subject to its law. .. . . The rules prescribed for thé construction of railroads, and for. their management and operation, designed to protect рersons and property otherwise endangered by their use, are strictly within the scope of local law. They are not, ixj. themselves, regulations of interstate commerce, although they control, in some degree, the conduct and the liability of thpse engaged in such commerce. So long as Congress has not legislаted upon the particular subject, they are rather to be regarded as legislation in aid of such commerce, and as a rightful exercise .of the police power of the State to regulate the relative rights and* duties of all persons and corporations within its limits.”
It was further said:
“The statute now in question, so far as it concerns liability for injuries happening within- the State of Iowa— which is the only matter presented for decision in this case — clearly comes within the same principles. It is in no just sense a regulation of commerce. It does not undertake to impose any tax upon the company, or to restrict the persons, or things to be cаrried, or to regulate the rate of tolls, fares, or freight. Its whole object and effect are to make it more sure that railroad companies shall perform the duties resting upon them by virtue of their employment as common carriers, to use the utmost care and diligence in the transportation of passengers and goods.”
Pennsylvania R. R. Co. v. Hughes, 191 U. S. 477, 491, may be cited as pertinent. It determined the validity of the common law of Pennsylvania, which prohibited the common carrier from limiting his liability for his own negligence, though the property was shipped from New York to a town in Pennsylvania under a bill of lading which contained a, clause limiting the carrier’s liability to a stip *419 ulatеd value in consideration of the rate paid, the shipper Mving been offered a bill of lading without such limitation on payment of a higher rate. The court quoted at length from the Solan case and concluded as follows:
“We can see no difference in the application of the principle based Upon the manner in which the State requires this degree оf care and responsibility, whether enacted into statute or resulting from the rules of law enforced in the state courts. The State has a right to promote the welfare and safety of those within its jurisdiction by requiring. common carriers to be ‘ responsible to the full measure of the loss resulting from their negligence, a contract to the contrary notwithstanding.”
There is a difference between that case and this — indeed some contrast. In that case a contract was made in Néw York which limited the liability of the carrier, the limitation being in accordance with the laws of that State; it was disregarded in Pennsylvania, where the act of negligence oсcurred, and the law. of the latter enforced. In this case the contract limiting liability was made in Michigan, the negligent act occurred in another State, and yet the limitation, it is insisted, is void. In other words, in that case the law of. the State was disregarded, in this case it is sought to be enforced. These, however, are but incidental cоntrasts, in no way affecting the basic principle of the cases, which was that the laws passed upon were exercises of the police power of the States in aid of interstate commerce, and although incidentally affecting it did not burden it.
Western Union Tel. Co.
v. James,
Another contention is made. It is urged that the statute as construed violates the Fourteenth Amendment of the Constitution of the United States, in that it abridges the privileges and immunities between citizens of the United States and deprives the telegraph company and the persons with whom it does business of their liberty and property without due process of law. The basis of this contention is the liberty of the telegraph company to make contracts. It is rather late in the day to make that contention. The. regulation of public service corporations is too well established, both as to power and the extent of the power, to call for any' discussion. It is true such power is not unlimited, nor. is the police power of the State, but the cases we have cited demonstrate that the statute of Michigan is not in excess of such powers.
Lastly, it is said that the statute deprives the telegraph company and the persons with whom it does business of the" equal protection of the laws. ' This is sought to be sustained on the ground that express companies and other common carriers may by contract limit their liability. The argument to sustain the contention is in effect that which we have considered. If an unjust discrimination is intended to be asserted,
