Justia U.S. 9th Circuit Court of Appeals Opinion Summaries

Plaintiff sued defendant, the Executive Officer of the California Air Resources Board ("CARB"), alleging that California's Vessel Fuel Rules ("VFR")violated federal statutory and constitutional grounds. At issue was whether the VFR was preempted by the Submerged Lands Act and whether the VFR was preempted by the Commerce Clause and Supremacy Clause. The court held that summary judgment in favor of the plaintiff was properly denied where plaintiff failed to demonstrate that the VFR was "otherwise 'unlawful and impermissibly regulate navigation and foreign and domestic commerce as delegated to the United States Congress'" under the Submerged Lands Act. The court also held that summary judgment in favor of the plaintiff was properly denied where the Commerce Clause or general maritime law should be used to bar a state from exercising its own police powers when such powers were used to combat severe environmental problems.

Plaintiffs filed a petition of review related to the Environmental Protection Agency's ("EPA")overall approval process of California's state implementation plan which contained limits on motor vehicle emissions for the years 2009 and 2012. At issue was whether the EPA's decision was arbitrary, capricious, an abuse of discretion, or otherwise contrary to law where the EPA's final determination was that the baseline budgets were "adequate" for transportation conformity purposes. The court denied the petition and held that the EPA's reading of its own regulations, which did not require an appropriate attainment demonstration, was reliable and therefore, did not compel an alternative reading to the EPA's interpretation.
