520 U.S. 154 (1997)
Decided March 19, 1997
Justice Scalia delivered the opinion of the Court
This case involved a challenge to a biological opinion issued by the Fish and Wildlife Service regarding the Klamath Irrigation Project's impact on endangered fish species. Two Oregon irrigation districts challenged water level restrictions imposed to protect endangered sucker fish in Clear Lake and Gerber reservoirs.
The Supreme Court:
The Court emphasized that:
This decision significantly expanded interpretations of standing and judicial review in environmental law, particularly for parties with economic interests in environmental regulations. It established that parties economically affected by environmental agency actions can challenge those actions in federal court, even when their interests may conflict with the environmental protection goals of the statute.
Bennett v. Spear broadened access to federal courts for judicial review of environmental agency decisions, allowing regulated parties and those economically impacted by environmental regulations to challenge agency actions more readily.
