Department of the Air Force v. Prutehi Guahan, fka Prutehi Litekyan

The Court will consider whether an Air Force permit-renewal application to Guam's regulator for continued hazardous-waste disposal can be immediately challenged in court as a final agency action (a completed agency decision). It will also consider whether the government must complete a National Environmental Policy Act review before filing that application under hazardous-waste permitting procedures.

No decision has been issued. Oral argument is scheduled for October 7, 2026, on whether the application is immediately reviewable and whether environmental review is required before it is submitted.

The answer could determine whether Guam residents and environmental groups can challenge an application before the territorial regulator acts. It could also affect whether the Air Force must conduct a broader environmental review before seeking to renew the permit.

Oral argument is scheduled for October 7, 2026. A decision would usually follow later in the same Court term.

The case concerns whether a hazardous-waste permit-renewal application can be challenged immediately and whether broad environmental review must precede it.

Guam residents, environmental groups, the Air Force, and territorial regulators could be affected by the timing of court challenges and environmental review.

The Supreme Court is scheduled to hear arguments on October 7, 2026. A decision would usually come later that term.
