In 2015, the NAM filed an amicus brief in the U.S. Court of Appeals for the Fifth Circuit supporting a federal judge’s decision not to impose excessive penalties on ExxonMobil for various permit violations. On remand to the district court, the groups reduced their requested penalties from $642 million to about $40 million, and the district judge awarded them about $20 million, prompting Exxon’s appeal back to the Fifth Circuit. In 2018 and 2021, the NAM filed additional amicus briefs arguing that the Constitution and Clean Air Act limit citizen suits under the Clean Air Act and asking the Fifth Circuit to enforce the constitutional line that limits federal courts to deciding discrete cases and controversies and prevents them from acting as regulators or policymakers.
Unfortunately, on August 30, 2022, the Fifth Circuit affirmed the district court's latest decision imposing a $14.25M penalty on defendant-appellants (for 3,651 purported violations). On, October 20, 2022, the NAM filed an amicus brief in support of Exxon’s petition for the 5th Circuit to rehear en banc its appeal challenging the district court’s penalty award.
Happily, on February 17, 2023, the 5th Circuit granted the petition for rehearing en banc and vacated the panel decision. On March 27, 2023, the NAM filed an amicus brief asking the full 5th Circuit to reverse the panel’s decision to enforce the limits of federal courts’ jurisdiction. This case is important to manufacturers because courts should exercise discretion in determining civil penalties to prevent creating perverse incentives for plaintiffs.
