25-5399 Panel Decision

J.E. Pendleton v. United States of America, et al.

The D.C. Circuit affirmed the district court's dismissal of the appellant's complaint, ruling that certain claims were patently insubstantial and failed to present a federal question. The court further held that sua sponte dismissal was proper under the Twombly pleading standard because the amended complaint lacked the required short and plain statement of claim.

Oladayo Ade Oladokun v. United States Department of Justice

The D.C. Circuit affirmed the district court's denial of a petition for a writ of mandamus, ruling that an agency's decision to initiate an investigation is discretionary and generally not subject to judicial review. The court also denied the appellant's motion to appoint counsel, finding he failed to demonstrate a likelihood of success on the merits.

SAMARA L. A. SIMMONS v. MARCO RUBIO, SECRETARY, U.S. DEPARTMENT OF STATE

The D.C. Circuit held that a timely motion for reconsideration by the Foreign Service Grievance Board renders the underlying order nonfinal, resetting the 180-day statute of limitations for judicial review. The court reversed the district court's dismissal of four counts challenging Board orders as time-barred while affirming the dismissal of a fifth count regarding the right to file further motions.

23-3054 Panel Decision

UNITED STATES OF AMERICA v. LINWOOD DOUGLAS THORNE

The D.C. Circuit affirmed Linwood Thorne's convictions for drug trafficking and firearms offenses, ruling that law enforcement's good-faith reliance on a cell-site-simulator warrant precluded suppression of evidence. The court declined to decide whether the magistrate judge lacked jurisdiction under Rule 41(b), holding instead that the officers' reasonable reliance on the warrant shielded the evidence from the exclusionary rule.

20-1107 Panel Decision

CLEAN FUELS ALLIANCE AMERICA v. ENVIRONMENTAL PROTECTION AGENCY AMERICAN FUEL & PETROCHEMICAL MANUFACTURERS, ET AL Consolidated with 20-1113

The D.C. Circuit dismissed consolidated petitions challenging the EPA's 2020 Renewable Fuel Standard because intervening statutory changes and the superseding 2022 Rule rendered the case moot. The court held that petitioners could not seek an advisory opinion on a future agency policy when the underlying legal framework had materially shifted.

25-5013 Panel Decision

ERNEST F. MITCHELL, LIEUTENANT v. JOHN PHELAN, HONORABLE

The D.C. Circuit affirmed the Navy's decision to deny Lieutenant Mitchell a promotion and remove him from the promotion list after he left his post as Command Duty Officer without authorization. The court held that the military's finding of substandard performance was reasonable and not arbitrary or capricious under administrative review standards.
