Environmental Law
531 U.S. 159 (2001) (U.S. Supreme Court)
Study notes for Solid Waste Agency of Northern Cook County v. U.S. Army Corps of Engineers (SWANCC): professor notes, cold call prep, exam angles, and memory aids.
The Army Corps of Engineers lacks authority under the Clean Water Act to regulate isolated, non-navigable waters based solely on their use by migratory birds.
In SWANCC, the Supreme Court addressed the limits of federal jurisdiction under the Clean Water Act (CWA) regarding isolated, non-navigable waters. The Court held that the Army Corps of Engineers could not assert jurisdiction over these waters solely based on their use by migratory birds, rejecting the Migratory Bird Rule as a sufficient basis for federal oversight. Professors may highlight the importance of this case in defining the scope of federal power under environmental statutes, as it reflects a trend toward limiting expansive interpretations of federal jurisdiction.
Moreover, professors might emphasize the implications of the ruling for environmental protection and state authority. The decision appears to shift some regulatory power back to the states, raising questions about the effectiveness of local versus federal environmental enforcement. Students should consider how this case affects future legislation and the protection of wetlands and other aquatic ecosystems that may not have clear navigable waters status.
SWANCC stops Corps’ reach—no Migratory Bird jurisdiction.
| Case | Distinction |
|---|---|
| Rapanos v. United States | While Rapanos similarly dealt with the limits of federal jurisdiction over waters, it involved a broader test for defining 'navigable waters' compared to the focused issue on migratory birds in SWANCC. |
| United States v. Riverside Bayview Homes | In Riverside Bayview, the Court upheld the Corps' authority over wetlands adjacent to navigable waters, contrasting with SWANCC’s emphasis on the isolation of non-navigable ponds. |
| Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc. | Chevron involves administrative agency authority and deference to interpretation, while SWANCC addresses jurisdictional limits under a specific environmental statute. |
Limiting federal jurisdiction encourages state control and local solutions that may be more tailored to specific environmental needs.
Restricting federal oversight risks weakening protections for ecologically significant waters and may lead to environmental degradation.
This case may appear on exams regarding the limits of federal regulatory authority under the CWA, particularly about non-navigable waters and the significance of the Migratory Bird Rule.
