Last week, the U.S. Supreme Court heard oral argument in two significant cases: Nat’l Assoc. of Mfr. v. Dep’t of Defense and Jesner v. Arab Bank, PLC.
In National Association of Manufacturers, the Court is being asked to determine which court is authorized to review the recent redefinition of “Waters of the United States” promulgated by the Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers (Corps of Engineers). The relevant statute is 33 U.S.C. § 1369(b)(1) and (2), and it is notorious for its complex provisions. If jurisdiction lies in the federal district courts, then many lawsuits are likely to be filed in courts throughout the country, creating uncertainty and stretching out the effective date of the new rule. If jurisdiction is limited to the courts of appeal, this should reduce the cost of litigation, but may be contrary to other provisions of the Clean Water Act (CWA).
