More severe storm surges and rising sea levels along the coast of the United States pose a threat to coastal communities, infrastructure, and ecosystems.

On May 25, 2023, the U.S. Supreme Court dropped an absolute bombshell with its ruling in Sackett v. Environmental Protection Agency. Early assessments of Sackett underscore two vital points: much has been lost for wetlands protection, and much has changed with respect to the Court’s broader environmental law jurisprudence. This Comment delves into both of these issues, providing some background on the unique and long-running controversy that was at the heart of Sackett, and parsing the four opinions from the case.

Since 2017, 115 North Atlantic right whales (NARWs) have been documented dead, seriously injured, or sporting sublethal injuries and illnesses. Scientists refer to this phenomenon as an unusual mortality event, and assert that entanglement and vessel strikes are the leading causes. Fewer than 350 NARWs remain, and it is estimated that only one-third of their deaths are documented. Experts claim that only “quick and decisive action from humans” can ensure the species’ survival. Some proposed regulations will affect where and how the relevant fisheries are able to operate.

The U.S. Supreme Court’s May ruling in Sackett v. Environmental Protection Agency sharply limited the scope of the federal Clean Water Act’s (CWA’s) protection for the nation’s waters. The Court redefined the Act’s coverage of “waters of the United States” (WOTUS), effectively removing protection from many wetlands that have been covered under the Act for almost a half century. On June 8, 2023, the Environmental Law Institute hosted a panel of experts that analyzed the consequences of Sackett and discussed what actions can be taken to protect non-WOTUS waters.
