versus

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.

L. B. Sullivan is one of three elected Commissioners of the City of Montgomery, Alabama. He has duties including supervision of the Police Department. He brought this civil libel action against the New York Times Company and four individual petitioners who were Alabama clergymen. The suit sought $500,000 in damages based on a full-page advertisement entitled "Heed Their Rising Voices" that appeared in the New York Times on March 29, 1960. A jury in the Circuit Court of Montgomery County awarded Sullivan the full amount claimed against all petitioners. The Supreme Court of Alabama affirmed the judgment. The advertisement was signed by the Committee to Defend Martin Luther King and the Struggle for Freedom in the South. It described widespread non-violent demonstrations by Southern Negro students and an unprecedented wave of terror against them. Two paragraphs formed the basis of the claim. One alleged that after students sang on the State Capitol steps their leaders were expelled, truckloads of police ringed the Alabama State College Campus, and the dining hall was padlocked to starve students into submission. The other stated that Southern violators had bombed Dr. King's home, assaulted him, arrested him seven times, and charged him with perjury. The text appeared over the names of 64 persons. It was endorsed by the individual petitioners among others. Sullivan contended that the references to police referred to him in his supervisory capacity. Six Montgomery residents testified that they read the statements as referring to him. However, several statements were inaccurate. The students sang the National Anthem rather than "My Country, 'Tis of Thee." The expulsions were for a different incident. The dining hall was not padlocked. Dr. King had been arrested only four times. The bombings occurred before Sullivan's tenure with police efforts to apprehend the perpetrators. The Times published the advertisement for approximately $4800. It acted upon an order from a New York advertising agency. The agency provided a letter from A. Philip Randolph certifying authorization. The Times made no efforts to confirm its accuracy against its own news files. Sullivan served written demands for retraction on the petitioners pursuant to Alabama law. None of the individual petitioners responded as they had not authorized use of their names. The Times did not retract. It published a retraction only upon demand by Governor John Patterson after learning more facts. The Supreme Court granted certiorari to the separate petitions of the individual petitioners and the Times due to the importance of the constitutional issues involved.

In 1965 New York City enacted the Landmarks Preservation Law, which created an eleven-member Landmarks Preservation Commission and authorized it to designate buildings at least thirty years old that possess special historical or aesthetic interest. The law required owners of designated landmarks to obtain Commission approval before altering exterior architectural features and imposed an affirmative duty to keep those features in good repair. In August 1967 the Commission designated Grand Central Terminal a landmark and the city tax block it occupies a landmark site; the Board of Estimate confirmed the designation the following month. Penn Central Transportation Co. and its affiliates owned the Terminal, an eight-story Beaux-Arts structure completed in 1913 that served as the main station for the New York Central and Harlem lines. On January 22, 1968, Penn Central entered a fifty-year renewable lease with UGP Properties, Inc., under which UGP agreed to construct a multistory office building cantilevered above the Terminal and to pay Penn Central at least three million dollars annually after construction. Penn Central and UGP submitted two plans prepared by architect Marcel Breuer: Breuer I, a fifty-five-story tower resting on the Terminal roof, and Breuer II Revised, a fifty-three-story building that would have removed part of the 42d Street facade. After four days of hearings at which over 80 witnesses testified, the Commission denied this application as to both proposals. Penn Central filed suit in New York Supreme Court, Trial Term, seeking a declaratory judgment, injunctive relief, and damages for a temporary taking. The trial court granted the injunctive and declaratory relief. The Appellate Division reversed, holding that Penn Central had failed to prove deprivation of all reasonable beneficial use. The New York Court of Appeals affirmed, concluding that the Terminal could still earn a reasonable return and that transferable development rights provided significant compensation. The Supreme Court noted probable jurisdiction.

The Village of Euclid is an Ohio municipal corporation that adjoins and is practically a suburb of the City of Cleveland. Its estimated population is between 5,000 and 10,000, and its area spans from twelve to fourteen square miles, with the greater part consisting of farm lands or unimproved acreage. It lies roughly in the form of a parallelogram measuring approximately three and one-half miles each way and is traversed east and west by three principal highways and two railroads. Ambler Realty Co. owns a tract of land containing 68 acres situated in the westerly end of the village. This tract abuts on Euclid Avenue to the south and the Nickel Plate railroad to the north. Adjoining this tract on both the east and the west, restricted residential plats have been laid out upon which residences have been erected. On November 13, 1922, the Village Council adopted an ordinance establishing a comprehensive zoning plan. The ordinance divides the village into six use districts denominated U-1 to U-6, three height districts denominated H-1 to H-3, and four area districts denominated A-1 to A-4. Appellee's tract is classified as U-2 for the first 620 feet north of Euclid Avenue, U-3 for the next 130 feet, and U-6 for the remainder. Enforcement of the ordinance is entrusted to the inspector of buildings under rules and regulations of the board of zoning appeals. The board holds public meetings, keeps minutes of its proceedings, and possesses authority to interpret the ordinance in cases of practical difficulty or unnecessary hardship, while penalties are prescribed for violations. Ambler Realty Co. filed suit alleging that the tract has been held for years for sale and development for industrial uses for which it is especially adapted. The bill further alleged that unrestricted market value is about $10,000 per acre but limited to residential purposes the value does not exceed $2,500 per acre, that the first 200 feet back from Euclid Avenue has a value of $150 per front foot if unrestricted but not in excess of $50 per front foot if limited to residential uses, and that the ordinance confiscates and destroys a great part of its value while deterring prospective buyers. The bill sought an injunction restraining enforcement of the ordinance. The district court overruled a motion to dismiss on the ground that the suit was premature. The district court held the ordinance unconstitutional and void and enjoined its enforcement.
