Editors' Summary: This index has been updated to include environmental justice case law since 1999. Following a brief narrative describing the expansion in scope of environmental justice claims, the author categorizes the case law as follows: Part I, Types of Disputes, describes the types of grievances that form the basis of these claims, such as the siting of facilities or housing in environmentally hazardous areas. Part II, Causes of Action, lists the federal statutes and constitutional amendments under which the claims arise. Part III, Cases, is an alphabetical listing of the cases and citations.
