What follows is an opinion from the Supreme Court of the United States. Your task is to determine the bases on which the Supreme Court rested its decision with regard to the legal provision that the Court considered in the case. Consider "judicial review (national level)" if the majority determined the constitutionality of some action taken by some unit or official of the federal government, including an interstate compact. Consider "judicial review (state level)" if the majority determined the constitutionality of some action taken by some unit or official of a state or local government. Consider "statutory construction" for cases where the majority interpret a federal statute, treaty, or court rule; if the Court interprets a federal statute governing the powers or jurisdiction of a federal court; if the Court construes a state law as incompatible with a federal law; or if an administrative official interprets a federal statute. Do not consider "statutory construction" where an administrative agency or official acts "pursuant to" a statute, unless the Court interprets the statute to determine if administrative action is proper. Consider "interpretation of administrative regulation or rule, or executive order" if the majority treats federal administrative action in arriving at its decision.Consider "diversity jurisdiction" if the majority said in approximately so many words that under its diversity jurisdiction it is interpreting state law. Consider "federal common law" if the majority indicate that it used a judge-made "doctrine" or "rule; if the Court without more merely specifies the disposition the Court has made of the case and cites one or more of its own previously decided cases unless the citation is qualified by the word "see."; if the case concerns admiralty or maritime law, or some other aspect of the law of nations other than a treaty; if the case concerns the retroactive application of a constitutional provision or a previous decision of the Court; if the case concerns an exclusionary rule, the harmless error rule (though not the statute), the abstention doctrine, comity, res judicata, or collateral estoppel; or if the case concerns a "rule" or "doctrine" that is not specified as related to or connected with a constitutional or statutory provision. Consider "Supreme Court supervision of lower federal or state courts or original jurisdiction" otherwise (i.e., the residual code); for issues pertaining to non-statutorily based Judicial Power topics; for cases arising under the Court's original jurisdiction; in cases in which the Court denied or dismissed the petition for review or where the decision of a lower court is affirmed by a tie vote; or in workers' compensation litigation involving statutory interpretation and, in addition, a discussion of jury determination and/or the sufficiency of the evidence.

McGEE v. INTERNATIONAL LIFE INSURANCE CO.
No. 50.

Stanley Hornsby argued the cause and filed a brief for respondent.
Opinion of the Court by
MR. Justice Black,
announced by Mr. Justice Douglas.
Petitioner, Lulu B. McGee, recovered a judgment in a California state court against respondent, International Life Insurance Company, on a contract of insurance. Respondent was not served with process in California but by registered mail at its principal place of business in Texas. The California court based its jurisdiction on a state statute which subjects foreign corporations to suit in California on insurance contracts with residents of that State even though such corporations cannot be served with process within its borders.
Unable to collect the judgment in California petitioner went to Texas where she filed suit on the judgment in a Texas court. But the Texas courts refused to enforce her judgment holding it was void under the Fourteenth Amendment because service of process outside California could not give the courts of that State jurisdiction over respondent. 288 S. W. 2d 579. Since the case raised important questions, not only to California but to other States which have similar laws, we granted certiorari. 352 U. S. 924. It is not controverted that if the California court properly exercised jurisdiction over respondent the Texas courts erred .in refusing to give its judgment full faith and credit. 28 U. S. C. § 1738.
The material facts are relatively simple. In 1944, Lowell Franklin, a resident of California, purchased a life insurance policy from the Empire Mutual Insurance Company, an Arizona corporation. In 1948 the respondent agreed with Empire Mutual to assume its insurance obligations. Respondent then mailed a reinsurance certificate to Franklin in California offering to insure him in accordance with the terms of the policy he held with Empire Mutual. He accepted this offer and from that time until his death in 1950 paid premiums by mail from his California home to respondent’s Texas office. Petitioner, Franklin’s mother, was the beneficiary under the policy. She sent proofs of his death to the respondent but it refused to pay claiming that he had committed suicide. It appears that neither Empire Mutual nor respondent has ever had any office or agent in California. And so far as the record before us shows, respondent has never solicited or done any insurance business in California apart from the policy involved here.
Since Pennoyer v. Neff, 95 U. S. 714, this Court has held that the Due Process Clause of the Fourteenth Amendment places some limit on the power of state courts to enter binding judgments against persons not served with process within their boundaries. But just where this line of limitation falls has been the subject of prolific controversy, particularly with respect to foreign corporations. In a continuing process of evolution this Court accepted and then abandoned “consent,” “doing business,” and “presence” as the standard for measuring the extent of state judicial power over such corporations. See Henderson, The Position of Foreign Corporations in American Constitutional Law, c. V. More recently in International Shoe Co. v. Washington, 326 U. S. 310, the Court decided that “due process requires only that in order to subject a defendant to a judgment in personam, if he be not present within the territory of the forum, he have certain minimum contacts with it such that the maintenance of the suit does not offend ‘traditional notions of fair play and substantial justice.’ ” Id., at 316.
Looking back over this long history of litigation a trend is clearly discernible toward expanding the permissible scope of state jurisdiction over foreign corporations and' other nonresidents. In part this is attributable to the fundamental transformation of our national economy over the years. Today many commercial transactions touch two or more States and may involve parties separated by the full continent. With this increasing nationalization of commerce has come a great increase in the amount of business conducted by mail across state lines. At the same time modern transportation and communication have made it much less burdensome for a party sued to defend himself in a State where he engages in economic activity.
Turning to this case we think it apparent that the Due Process Clause did not preclude the California court from entering a judgment binding on respondent. It is sufficient for purposes of due process that the suit was based on a contract which had substantial connection with that State. Cf. Hess v. Pawloski, 274 U. S. 352; Henry L. Doherty & Co. v. Goodman, 294 U. S. 623; Pennoyer v. Neff, 95 U. S. 714, 735. The contract was delivered in California, the premiums were mailed from there and the insured was a resident of that State when he died. It cannot be denied that California has a manifest interest in providing effective means of redress for its residents when their insurers refuse to pay claims. These residents would be at a severe disadvantage if they were forced to follow the insurance company to a distant State in order to hold it legally accountable. When claims were small or moderate individual claimants frequently could not afford the cost of bringing an action in a foreign forum— thus in effect- making the company judgment proof. Often the crucial witnesses — as here on the company’s defense of suicide — will be found in the insured’s locality. Of course there may be inconvenience to the insurer if it is held amenable to suit in California where it had this contract but certainly nothing which amounts to a denial of due process. Cf. Travelers Health Assn. v. Virginia ex rel. State Corporation Comm’n, 339 U. S. 643. There is no contention that respondent did not have adequate notice of the suit or sufficient time to prepare its defenses and appear.
The California statute became law in 1949, after respondent had entered into the agreement with Franklin to assume Empire Mutual’s obligation to him. Respondent contends that application of the statute to this existing contract improperly impairs the obligation of the contract. We believe that contention is devoid of merit. The statute was remedial, in the purest sense of that term, and neither enlarged nor impaired respondent’s substantive rights or obligations under the contract. It did nothing more than to provide petitioner with a California forum to enforce whatever substantive rights she might have against respondent. At the same time respondent was given a reasonable time to appear and defend on the merits after being notified of the suit. Under such circumstances it had no vested right not to be sued in California. Cf. Bernheimer v. Converse, 206 U. S. 516; National Surety Co. v. Architectural Decorating Co., 226 U. S. 276; Funkhouser v. J. B. Preston Co., 290 U. S. 163.
The judgment is reversed and the cause is remanded to the Court of Civil Appeals of the State of Texas, First Supreme Judicial District, for further proceedings not inconsistent with this opinion.
It is so ordered.
