The relevant law is the Administrative Procedures Act [1], which this court found “provides that courts must ‘hold unlawful and set aside agency action’ that is ‘in excess of statutory jurisdiction, authority, or limitations, or short of statutory right’; ‘arbitrary’ or ‘capricious’; or ‘otherwise not in accordance with law.’ U.S.C. § 706(2).”
(There are also issues under the FACA [2].)
