In 1966 the Pennsylvania Legislature enacted the Bituminous Mine Subsidence and Land Conservation Act to address land subsidence caused by underground coal mining. The Act authorizes the Department of Environmental Resources to implement and enforce a comprehensive program preventing or minimizing subsidence and consequent damage to surface structures. Section 4 prohibits mining that causes subsidence damage to public buildings, dwellings used for human habitation, and cemeteries, and generally requires that 50 percent of the coal beneath such structures remain in place to provide surface support. Petitioners are an association of coal producers and several of its member corporations engaged in underground bituminous coal mining in western Pennsylvania. They own, lease, or control substantial coal reserves and associated support estates beneath surface properties affected by the Subsidence Act. Many of these interests were severed from the surface estate between 1890 and 1920, and petitioners or their predecessors typically acquired waivers of liability for subsidence damage along with rights to deposit wastes, provide drainage and ventilation, and erect surface facilities. In 1982 petitioners filed a civil rights action in the United States District Court for the Western District of Pennsylvania against the Secretary of the Department of Environmental Resources and other officials. They sought to enjoin enforcement of the Subsidence Act and its implementing regulations, alleging that Section 4 and Section 6 effected a taking of their property without compensation and that Section 6 impaired their contractual obligations. The parties entered a stipulation of facts concerning the facial challenge and filed cross-motions for summary judgment. The District Court granted summary judgment in favor of the Department officials. The Court of Appeals for the Third Circuit affirmed. The Supreme Court granted certiorari to consider the constitutional challenges to the Subsidence Act. Petitioners have never claimed that the Subsidence Act makes it commercially impracticable for them to continue mining their bituminous coal interests in western Pennsylvania, nor have they identified any specific mine rendered unprofitable by the statute. The evidence in the record shows that enforcement of the 50 percent rule has required petitioners to leave less than 27 million tons of coal in place. This applies across 13 mines containing over 1.46 billion tons. It amounts to less than 2 percent of the total coal in those operations.

In the early 1980s, the Tahoe Regional Planning Agency imposed two moratoria on development in the Lake Tahoe Basin. The first, Ordinance 81-5, took effect on August 24, 1981, and lasted until August 26, 1983. The second, Resolution 83-21, ran from August 27, 1983, to April 25, 1984. Together these measures prohibited virtually all development on sensitive lands for a total of 32 months while TRPA developed a comprehensive land-use plan. Lake Tahoe's exceptional water clarity had begun to deteriorate due to increased land development starting in the late 1950s and early 1960s. Runoff from impervious surfaces on steeper slopes and stream environment zones carried nutrients that promoted algae growth. In response, California and Nevada, along with the federal government, amended the Tahoe Regional Planning Compact in 1980 to require TRPA to establish environmental threshold carrying capacities and adopt a regional plan. The 1980 Compact amendment directed TRPA to adopt thresholds within 18 months and a plan within a year thereafter. It also included a finding that temporary halts on development were necessary to preserve the region's capacity for future development consistent with the ultimate plan. TRPA enacted Ordinance 81-5 in June 1981 after concluding it could not meet the original deadlines, and later adopted Resolution 83-21 when no plan was in place by August 1983. Petitioners, including the Tahoe-Sierra Preservation Council representing about 2,000 owners and a class of approximately 400 individual owners of vacant lots purchased before 1980 primarily for building single-family homes, filed parallel actions in federal courts in Nevada and California shortly after the 1984 plan was adopted. The suits were consolidated in the District of Nevada. The District Court found that the moratoria constituted categorical takings under Lucas because they temporarily deprived owners of all economically viable use. The Ninth Circuit reversed that determination. The Ninth Circuit held that the temporary nature of the regulations meant no categorical taking had occurred and that Penn Central analysis applied, though petitioners had not challenged the District Court's Penn Central findings. The Supreme Court granted certiorari to address whether the moratoria effected per se takings.

In 1970, Teleprompter Manhattan CATV Corp. obtained a permit from New York City to operate a cable television system in Manhattan. It entered into an agreement with the prior owner of a five-story apartment building at 303 West 105th Street to install cables on the roof in exchange for a flat fee of $50 per year. The installation included a cable slightly less than one-half inch in diameter and approximately 30 feet in length running along the roof about 18 inches above the surface. It also included directional taps measuring approximately 4 inches by 4 inches by 4 inches on the front and rear of the roof. Two large silver boxes were placed along the roof cables. Additional cable was extended another 4 to 6 feet. All components were attached by screws or nails penetrating the masonry at approximately two-foot intervals. In 1971, Jean Loretto purchased the building. At the time of purchase the cable installation was already in place as part of a larger network serving adjacent buildings, though Loretto did not discover its existence until after she took possession. Two years later Teleprompter connected a noncrossover line by dropping a cable down the front of the building to serve Loretto's own tenants. In 1973 the New York Legislature enacted section 828 of the Executive Law, effective January 1, 1973, which prohibited landlords from interfering with cable television installations on their property, barred landlords from demanding payment from tenants for permitting service, and limited any payment from a cable company to an amount the State Commission on Cable Television determined to be reasonable; the Commission later set the presumptive fee at a one-time $1 payment. In 1976 Loretto filed a class action against Teleprompter in New York Supreme Court on behalf of all owners of real property in the state on which Teleprompter had placed cable components, alleging trespass and a taking without just compensation and seeking damages and injunctive relief; the City of New York, which had granted Teleprompter an exclusive franchise for parts of Manhattan, intervened as a defendant. The Supreme Court, Special Term, granted summary judgment to Teleprompter and the city. The Appellate Division affirmed without opinion. The New York Court of Appeals upheld the statute. The Supreme Court of the United States noted probable jurisdiction.

The Nollans own a beachfront lot in Ventura County, California. A concrete seawall approximately eight feet high separates the beach portion of their property from the rest of the lot. The historic mean high tide line determines the lot's oceanside boundary. The Nollans originally leased their property with an option to buy, and the building on the lot was a small bungalow totaling 504 square feet. The Nollans' option to purchase was conditioned on their promise to demolish the bungalow and replace it. On February 25, 1982, they submitted a permit application to the California Coastal Commission proposing to demolish the existing structure and replace it with a three-bedroom house. The Commission informed them that the permit would be granted subject to the condition that they allow the public an easement to pass across a portion of their property bounded by the mean high tide line and their seawall. On June 3, 1982, the Nollans filed a petition for writ of administrative mandamus in the Ventura County Superior Court to invalidate the access condition. The court remanded the case to the Commission for a full evidentiary hearing. After the hearing, the Commission reaffirmed the condition. The Superior Court ruled in favor of the Nollans on statutory grounds and directed that the permit condition be struck. While the Commission's appeal to the California Court of Appeal was pending, the Nollans tore down the bungalow, built the new house, and bought the property. The Court of Appeal reversed the Superior Court. The Nollans appealed to this Court, raising only the constitutional question.
