In the span of just a few years, the U.S. Supreme Court has brought the venerable constitutional concept of federalism back to life with a vengeance. In the 1999 Term alone, the Rehnquist Court struck down three federal laws for violating basic principles of federalism and narrowly construed a fourth to avoid any conflict with those precepts.

Editors' Summary: In recent years, vindication of private-property rights has been the rallying cry of various citizen groups and politicians who believe that certain regulatory restrictions—especially environmental protection measures—have "gone too far" and that the Fifth Amendment is an insufficient safeguard of private-property rights.

On June 29, 2001, the last day of the October 2000 term, the U.S. Supreme Court granted certiorari to consider "whether the [Ninth Circuit] Court of Appeals properly determined that a temporary moratorium on land development does not constitute a taking of property requiring compensation under the Takings Clause of the [U.S.] Constitution?" The case, Tahoe-Sierra Preservation Council, Inc. v. Tahoe Regional Planning Agency, provides the Court with an opportunity to clarify its opinions in First English Evangelical Lutheran Church of Glendale v.

The U.S. Supreme Court's recent campaign to curtail congressional authority to legislate under the U.S. Commerce Clause has inevitably fostered speculation about the validity of parts of the Clean Water Act (CWA), the Endangered Species Act (ESA) and other federal environmental laws—heightened by the Court's recent decision to hear just such a claim. One view is that the decisions since United States v.

Editors' Summary: Pfiesteria piscicida, a sometimes toxic microorganism, is responsible for the death of millions of fish in Delaware, Maryland, North Carolina, and Virginia. Although the problem of Pfiesteria-related fish kills is associated with the Mid-Atlantic region, other toxic microorganisms have threatened fish and marine wildlife throughout the world. Scientists attribute this "global epidemic" of toxic microbes to excessive nutrient loading from nonpoint sources of pollution.

Editors' Summary: During congressional debate on CERCLA reauthorization, attention has focused on the role of states in executing the Act. Some observers of these debates have questioned the constitutionality of delegating EPA cleanup and enforcement authorities to states. In contrast, this Article argues that such delegation is permissible under the U.S. Constitution and constitutional jurisprudence. The author asserts that under the Appointments Clause, the delegation of CERCLA authorities to states would not usurp Executive Branch functions.

The regulatory takings jurisprudence of the U.S. Supreme Court has become an ungainly body, awkward for citizens and judges to apply and challenging as well, one might guess, for the Court itself, as it continues to reshape the law to better serve its aims. One cause of this predicament: leading decisions have arisen from peculiar facts and messy procedural contexts, yielding rulings that are hard to apply elsewhere. Another cause: the divergent views of Court members on the deference properly due the work of land use regulators.

To the extent the city argues that, as a matter of law, its landuse decisions are immune from judicial scrutiny under all circumstances, its position is contrary to settled regulatory takings principles. We reject this claim of error.

Improperly planned urban development has resulted in catastrophic sprawl. The present land use zeitgeist hails urban and suburban mixed-use zoning as the solution. Mixed-use zoning combines—rather than segregates—residential, commercial, and sometimes industrial land uses, and thereby decreases housing costs, decreases commuting periods, decreases vehicle miles traveled and air emissions, increases the efficient use of land and time, and increases consumer convenience.

Smart Growth admits of no clear definition. It provides a popular label for a growth strategy that addresses current concerns about traffic congestion, disappearing open space, nonpoint source pollution, the high cost of housing, increasing local property taxes, longer commutes, and the diminishing quality of community life. To accomplish smart growth, government must take two related actions. The first is the designation of discrete geographical areas into which private market growth pressures are directed.
