Editors' Summary: Until recently, the regulation of chemical carcinogens and the regulation of radiological carcinogens developed independently. Different governmental agencies operating under different statutory directives were responsible for addressing the dangers from these carcinogens. As a result, different policies and practices were developed. This Article explores these differences and the record on resolving them. It first examines the history of federal regulation of chemical and radiological carcinogens and summarizes EPA's approach to risk assessments for them.

Editors' Summary: This Article addresses the effect of the U.S. Constitution's Takings Clause on the government's authority to protect environmental resources. An earlier Article, published in the May 1994 of ELR, analyzed bases for government regulation provided by limitations inherent in the property right itself. In contrast, this Article focuses on an emerging doctrine of sustainable use, rooted in background principles of nuisance law and the government's complementary police power.

Editors' Summary: Environmental regulation has come under increasing attack from those who argue that governmental limitations on property use violate constitutional restrictions on regulatory takings of property. The author addresses this controversy by focusing on the background limitations on owners' rights that are inherent in property law itself, as opposed to the external controls that government may impose under the doctrines of police power and nuisance.

Is an intentional temporary deprivation of the use of land not a "temporary taking"? This proposition was asserted by a panel of the U.S. Court of Appeals for the Ninth Circuit in Tahoe-Sierra Preservation Council, Inc. v. Tahoe Regional Planning Agency. The Ninth Circuit denied en banc review, despite a strong dissent by Judge Alex Kozinski. Perhaps because it had never explicated the meaning of "temporary taking," and perhaps in part because its interest was kindled by the Kozinski dissent, the U.S. Supreme Court recently granted certiorari. The question is limited to:

Editors' Summary: Since 1910, the federal government has played a role in regulating pesticides. At first, the motive was to fight fraud, but as pesticides became more sophisticated and as environmental concerns grew, the government's regulatory efforts became more comprehensive. Now, near the dawn of bioengineered pesticides, with society confronting and reevaluating environmental risks, and with agencies facing fiscal challenges, pesticide regulation continues to evolve. It is a field of concern to the pesticide industry, of course, but in U.S.

Editor's Summary: In 2003, the U.S. Supreme Court issued its most recent pronouncement on the executive foreign affairs preemption doctrine in American Insurance Ass'n v. Garamendi. In this Article, Kimberly Breedon argues that lower courts are prone to overbroad applications of Garamendi because the Court assumed the presence of three elements when it developed the standard for executive foreign affairs preemption of state law: (1) formal source law; (2) nexus to a foreign entity; and (3) indication of intent by the executive to preempt the state law under challenge.
