economic impact of the regulation

In 1986, petitioner David H. Lucas purchased two residential lots on the Isle of Palms in Charleston County, South Carolina, for $975,000. He intended to construct single-family homes on the parcels, which at the time were zoned for such use and required no building permit for development. No portion of the lots qualified as a critical area under then-existing coastal zone legislation. Subsequently, in 1988, the South Carolina Legislature enacted the Beachfront Management Act. The legislation established a baseline and prohibited construction of occupable improvements seaward of a line drawn 20 feet landward of that baseline, directly affecting Lucas's parcels by barring any permanent habitable structures. Lucas filed an action in the Court of Common Pleas alleging that the Act's restrictions effected a taking of his property without just compensation. Following a bench trial, the court determined that the prohibition rendered the lots valueless and ordered the state to pay just compensation in the amount of $1,232,387.50. The Supreme Court of South Carolina reversed the trial court's judgment. It accepted the legislature's findings that new construction threatened public resources and concluded that a regulation designed to prevent serious public harm could not constitute a taking. The United States Supreme Court granted certiorari to review the South Carolina Supreme Court's decision.

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.

Eastern Enterprises was organized as a Massachusetts business trust in 1929 under the name Eastern Gas and Fuel Associates. Until 1965, Eastern conducted extensive coal mining operations centered in West Virginia and Pennsylvania. As a signatory to each National Bituminous Coal Wage Agreement executed between 1947 and 1964, Eastern made contributions of over $60 million to the 1947 and 1950 Welfare and Retirement Funds. In 1963, Eastern decided to transfer its coal-related operations to a subsidiary, Eastern Associated Coal Corp. The transfer was completed by the end of 1965. It was described in Eastern's federal income tax return as an agreement by EACC to assume all of Eastern's liabilities arising out of coal mining and marketing operations in exchange for Eastern's receipt of EACC's stock. Eastern retained its stock interest in EACC through a subsidiary corporation, Coal Properties Corp., until 1987. It received dividends of more than $100 million from EACC during that period. In 1987, Eastern sold its interest in Coal Properties Corp. to Peabody Holding Company, Inc. Following enactment of the Coal Industry Retiree Health Benefit Act of 1992, the Commissioner of Social Security assigned to Eastern the obligation for Combined Fund premiums respecting over 1,000 retired miners who had worked for the company before 1966. The assignment rested on Eastern's status as the pre-1978 signatory operator for whom the miners had worked for the longest period of time. Eastern's premium for a 12-month period exceeded $5 million. Eastern responded by suing the Commissioner, as well as the Combined Fund and its trustees, in the United States District Court for the District of Massachusetts. Eastern asserted that the Coal Act, either on its face or as applied, violates substantive due process and constitutes a taking of its property in violation of the Fifth Amendment. The District Court granted summary judgment for respondents on all claims. The Court of Appeals for the First Circuit affirmed. The Supreme Court granted certiorari.

In 1997, the State of Hawaii had a highly concentrated wholesale oil market due to its small size and isolation over 1,600 miles from the mainland, with only two refineries and six gasoline wholesalers operating in the state. Chevron U.S.A. Inc. was the largest refiner and marketer, controlling 60 percent of the in-state gasoline market and 30 percent of the wholesale market on Oahu. Gasoline was sold at retail through approximately 300 service stations, about half leased by oil companies to independent lessee-dealers. Chevron operated 64 such lessee-dealer stations under arrangements where it leased land, constructed stations, and leased them to dealers while setting wholesale prices and requiring supply contracts. In June 1997, the Hawaii Legislature enacted Act 257, which capped the rent oil companies could charge lessee-dealers at 15 percent of gross profits from gasoline sales plus 15 percent of other product sales, and imposed other restrictions on station ownership. Thirty days after enactment, Chevron filed suit in the United States District Court for the District of Hawaii against the Governor and Attorney General, challenging the rent cap. The parties stipulated that the cap would reduce aggregate rent on 11 of Chevron's stations by about $207,000 per year but allow increases on the remaining 53, potentially raising overall rental income by nearly $1.1 million annually, and that Chevron had not recovered station maintenance costs through rent alone over the past 20 years. The District Court granted summary judgment to Chevron. On appeal, the Ninth Circuit vacated the judgment and remanded the case. After a one-day bench trial featuring competing expert economists, the District Court entered judgment for Chevron. The Ninth Circuit affirmed, and the Supreme Court granted certiorari in 2004.
