Editors' Summary: The U.S. Supreme Court ruled on three takings cases in its 2004 term: Lingle v. Chevron U.S.A., Inc.; Kelo v. City of New London; and San Remo Hotel, Ltd. Partnership v. City & County of San Francisco. In Lingle, the Court struck down the "substantially advance" test set forth in Agins v. City of Tiburon. Kelo, which gained attention from the media and public, upheld the use of eminent domain for economic development purposes. And San Remo involved a relatively straightforward procedural issue.

The government use of compulsory purchase and land use control powers appears to be increasing worldwide as competition for useable and livable space increases. The need for large and relatively undeveloped space for agriculture and conservation purposes often competes with the need for shelter and the commercial and industrial development accompanying such development for employment, product production and distribution, and other largely urban uses.

Editors' Summary: Property rights advocates implicitly complained in Babbitt v. Sweet Home Chapter of Communities for a Great Oregon that a Fish and Wildlife Service regulation that aimed to protect endangered and threatened species by defining "harm" to include habitat modification impinged on their rights as private landowners by asking them to share with the government responsibility for protecting such species. The U.S. Supreme Court upheld the regulation as reasonable given the relevant language of the Endangered Species Act.

The bedrock notion that courts should, in the overwhelming majority of cases, defer to lawmakers is currently under attack in the nation's courts, commentary, and classrooms. Leading the way are several U.S. Supreme Court Justices who, in cases involving the U.S. Commerce Clause, Takings Clause, and §5 of the Fourteenth Amendment of the U.S. Constitution, are much more willing than their immediate predecessors to second-guess the motives and tactics of elected and appointed officials at all levels of government.

One of the most fundamental tenets of toxicology is that "the dose determines the poison." This simple phrase provides the basis for the belief that all agents—chemicals and physical phenomena that are capable of producing some effect—have the potential to cause toxicity. Whether toxicity actually occurs is principally a matter of dose: the greater the exposure to a given agent, the more pronounced or severe the response of a cell or organism.
