미국 토지수용사건에서 연방대법원 판례와 주대법원 판례의 발전과 현재

Abstract The United States' eminent domain law has developed around the principle of "just compensation for a public purpose" of the Fifth Amendment to the Constitution. Initially, the uncompensated eminent domain was not a major issue due to the vast land area and undeveloped land, but after the Constitutional amendment, the balance between property rights protection and public purposes emerged as an important issue. This legal principle was formed and developed through major precedents. The major precedents of the United States Supreme Court and state supreme courts that developed the United States' eminent domain law are as follows. In the Penn Central case (1978), the United States Supreme Court established the standard for judging regulatory eminent domain (Penn Central Test) and judged whether the regulation was an eminent domain requiring just compensation through three factors: the economic impact of the regulation, investment expectations, and the nature of the government action. In the Loretto case (1982), the United States Supreme Court presented the standard that permanent physical occupation is considered a natural eminent domain requiring just compensation even if the area is small. In the First English case (1987), the principle that temporary restrictions are also recognized as takings and that compensation is required under the Constitution was established. In the Nollan case (1987), the standard was established that there must be an essential connection between the conditions of a development permit and the public interest purpose. In the Lucas case (1992), the total takings test was established, stating that if a regulation deprives the land of all economic value, it constitutes taking and requires just compensation. In the Dolan case (1994), the U.S. Supreme Court additionally suggested the proportionality standard that the conditions of a permit must be roughly proportional to the impact of the development. In the Kelo case (2005), it was ruled that public takings for economic development purposes are also constitutionally permitted, and takings for private purposes are also possible if the public interest purpose is recognized. Looking at cases of the state Supreme Court that are not well-introduced in Korea, the Bay Point Properties case (Mississippi) strengthened the discretion of administrative agencies by ruling that changes in the use of a local area can be permitted without additional compensation if they are for the public interest purpose, and the City of Chicago v. In the Eychaner case (Illinois), the concept of public interest was expanded by judging that private development projects to prevent future devastation are also recognized as public interest. In addition, the Board of County Commissioners v. Krier case (Colorado) reaffirmed the principle that future development potential should be considered when calculating land compensation, and in the City of Marietta v. Summerour case (Georgia), the government agency's expropriation was invalidated due to procedural violations, and the protection of landowner rights was also strengthened. In 2024, the U.S. Supreme Court made an important ruling related to land compensation. In the Sheetz case, it ruled that legislative permit conditions should also be strictly reviewed according to the Nollan/Dolan standard, which affected the development cost sharing policy of local governments, and in the DeVillier case, it was emphasized that flood damage caused by flood prevention facilities can also be recognized as indirect expropriation and remedies under state law. In conclusion, the U.S. expropriation law, formed by the precedents of the U.S. Supreme Court and state supreme courts, shows the process of legal development to find a balance between private property rights and public purposes. Key decisions by federal and state Supreme Courts have helped to establish the line between property rights protection and government regulation by embodying the constitutional doctrine of just compensation in a variety of situations, including regulatory takings, physical occupancy, and permit conditions.
