Tompkins, a citizen of Pennsylvania, was injured on a dark night by a passing freight train of the Erie Railroad Company while walking along its right of way at Hughestown in that State. He claimed that the accident occurred through negligence in the operation or maintenance of the train. He asserted that he was rightfully on the premises as a licensee because he was on a commonly used beaten footpath which ran for a short distance alongside the tracks. He further alleged that he was struck by something which looked like a door projecting from one of the moving cars. To enforce that claim he brought an action in the federal court for southern New York, which had jurisdiction because the company is a corporation of that State. The Erie insisted that its duty to Tompkins was no greater than that owed to a trespasser. It contended, among other things, that its duty to Tompkins, and hence its liability, should be determined in accordance with the Pennsylvania law; that under the law of Pennsylvania, as declared by its highest court, persons who use pathways along the railroad right of way are to be deemed trespassers; and that the railroad is not liable for injuries to undiscovered trespassers resulting from its negligence, unless it be wanton or wilful. Tompkins denied that any such rule had been established by the decisions of the Pennsylvania courts. He contended that, since there was no statute of the State on the subject, the railroad's duty and liability is to be determined in federal courts as a matter of general law. The trial judge refused to rule that the Pennsylvania law precluded recovery. The jury brought in a verdict of $30,000. The judgment entered thereon was affirmed by the Circuit Court of Appeals, which held that it was unnecessary to consider whether the law of Pennsylvania was as contended, because the question was one not of local, but of general, law and that upon questions of general law the federal courts are free, in the absence of a local statute, to exercise their independent judgment as to what the law is. Because of the importance of the question whether the federal court was free to disregard the alleged rule of the Pennsylvania common law, the Supreme Court granted certiorari.

In January 1990, Dr. Ira Gore, Jr., purchased a black BMW sports sedan for $40,750.88 from an authorized dealer in Birmingham, Alabama. The vehicle had been manufactured in Germany by BMW and shipped to the United States, where an independent service company in Brunswick, Georgia, determined that its finish had been damaged by acid rain during transit from Europe and refinished it at a cost of $601.37 before delivery to the Birmingham dealership. At the time of the purchase, BMW of North America, Inc., maintained a policy of not disclosing to dealers or customers that a new vehicle had been refinished if the cost of the repairs was less than 3 percent of the suggested retail price, and the refinishing cost for Gore's car amounted to approximately 1.5 percent of that price. After driving the car for about nine months, Gore took it to an independent detailer, who informed him that the car had been repainted. Gore then filed suit against BMW of North America, Inc., alleging fraud under Alabama law for the failure to disclose the repainting. At trial, BMW acknowledged that it had sold approximately 983 refinished cars as new in the United States since 1983, including 14 in Alabama, without disclosing the repairs when the cost exceeded $300 per vehicle. The jury awarded Gore $4,000 in compensatory damages, representing the difference in value between the car as delivered and its value had it not been refinished, along with $4 million in punitive damages. BMW moved to set aside the punitive damages award, introducing evidence that its nondisclosure policy aligned with the laws of roughly 25 states that required disclosure only for repairs exceeding 3 percent of the suggested retail price. The trial court denied the motion. On appeal, the Alabama Supreme Court affirmed the judgment but reduced the punitive damages to $2 million after applying factors from Green Oil Co. v. Hornsby and Pacific Mutual Life Insurance Co. v. Haslip, concluding that the jury's award was excessive but that $2 million remained permissible. The Supreme Court of the United States granted certiorari to review the case.

In March 1963 Ernesto Miranda was arrested at his home in Phoenix and taken to the police station where he was identified by the complaining witness. He was then questioned by two officers in Interrogation Room No. 2 for two hours. The officers did not advise him of any right to counsel. Miranda signed a typed confession that was introduced at his trial for kidnapping and rape. On October 14 1960 Michael Vignera was arrested in connection with a Brooklyn robbery. He was taken first to the 17th Detective Squad headquarters in Manhattan and later to the 66th Detective Squad. A detective questioned him for several hours without any advice concerning counsel. Vignera made an oral admission. He was then questioned by an assistant district attorney whose transcribed statement was also introduced at his trial for first-degree robbery. On March 20 1963 Carl Calvin Westover was arrested by Kansas City police as a suspect in two local robberies. Kansas City police interrogated Westover on the night of his arrest. The next day local officers interrogated him again throughout the morning. Westover was then turned over to FBI agents who questioned him for two to two-and-a-half hours about California robberies and obtained signed confessions. At the time the FBI agents began questioning Westover he had been in custody for over fourteen hours. On January 31 1963 Roy Allen Stewart was arrested at his home in connection with a series of purse-snatch robberies. During the next five days police interrogated Stewart on nine different occasions without any advice of rights. On the ninth session Stewart confessed. Transcripts of the interrogations were introduced at his trial for kidnapping rape and murder. The Arizona Supreme Court affirmed Miranda's conviction. The New York courts affirmed Vignera's conviction. The Ninth Circuit affirmed Westover's conviction. The California Supreme Court reversed Stewart's conviction. The Supreme Court granted certiorari in the four cases and consolidated them for argument.

The City of Chicago, acting under an 1872 Illinois statute that became part of its charter in 1875, passed an ordinance on October 9, 1880, to open and widen Rockwell Street from West 18th Street to West 19th Street by condemning parcels of land owned by individuals and parts of the right of way of the Chicago, Burlington and Quincy Railroad Company within the city limits. On November 12, 1890, the city filed a petition in the Circuit Court of Cook County seeking condemnation of the property and asking that just compensation be ascertained by a jury, with the railroad company admitted as a defendant along with other interested parties. The jury awarded one dollar as just compensation to the railroad company for the parts of its right of way to be used for the street, while awarding compensation to individual owners for their parcels. The railroad moved for a new trial, which was overruled, and final judgment was entered in execution of the award. The judgment was affirmed by the Supreme Court of Illinois in 149 Illinois 457. After affirmance the railroad company sued out a writ of error to the United States Supreme Court. The railroad had raised claims under the Fourteenth Amendment in its motion for new trial and in its assignment of errors filed in the state supreme court. The Illinois statute provided no provision for an answer by defendants in condemnation proceedings, but the railroad asserted its federal claims in the written motion to set aside the verdict and grant a new trial.
