Louisiana v. DOE, No. 22-60146 (5th Cir. 2024)
Annotate this CaseIn 2022, the Department of Energy (DOE) repealed regulations, known as the 2020 Rules, that had created new classes of dishwashers and laundry machines with shorter cycle times, arguing the 2020 rules were illegal. Several states, led by Louisiana, petitioned for the review of the repeal. The United States Court of Appeals for the Fifth Circuit ruled in favor of the states, finding that the DOE's repeal was arbitrary and capricious for failing to consider the performance characteristics of the appliances, the substitution effects, and the evidence showing that the Department’s conservation standards were leading Americans to use more energy and water. The court also noted that the DOE failed to consider other remedies short of repealing the 2020 rules entirely. The court did not reach a conclusion on whether the DOE had the statutory authority to regulate water use in dishwashers and clothes washers. The court granted the petition and remanded the case back to the DOE for further proceedings consistent with its opinion.
