CLUE is a storehouse for tracking and sharing case law updates on the environment.
The Center for Environmental Excellence by AASHTO maintains CLUE and keeps all content
relevant. CLUE provides a timely, organized, and comprehensive list of case law
summaries for policy makers and practitioners. The database primarily includes recent
court decisions involving challenges to environmental reviews and permits for highway
and transit projects. The Center will continue to expand the database over time
to include additional court decisions, so please check back often.
Anyone can view the CLUE database. Use the tool bar at the top of each page to view
CLUE's organized and topical list of updates. Or get started by selecting a statute
