The Court ruled they could sue under federal law allowing court review of agency actions to challenge EPA’s authority to regulate it, overturned the Ninth Circuit’s ruling, and sent the case back (reversed and remanded); whether they could challenge the order’s terms remains unresolved.

Justice Ginsburg noted that the EPA order threatened the Sacketts with tens of thousands of dollars in daily civil penalties; they sued to dispute the agency’s authority over their property.
