Attorney Dylan Thayer to Argue Military Promotion Case Before the D.C. Circuit: Mitchell v. Phelan

SCOTUS on VA Appeals

The Law Offices of David P. Sheldon, PLLC, announced that Attorney Dylan Thayer will present oral argument before the U.S. Court of Appeals for the District of Columbia Circuit on Friday, November 21, 2025, in the case Ernest F. Mitchell v. John Phelan, Secretary of the Navy (Case No. 25-5013).

At issue in this appeal is whether the Navy violated federal law when it delayed a service member’s promotion beyond the statutory 18-month limit set by 10 U.S.C. § 624(d)(5)—and whether that delay automatically entitled Lieutenant Mitchell to promotion “by operation of law.” The case also challenges the Navy’s decision to issue a “detachment for cause”, alleging it was based on arbitrary findings inconsistent with military regulations and fairness standards.

Mitchell, a decorated officer with over a decade of service, was selected and Senate-confirmed for promotion to Lieutenant Commander before the Navy delayed his advancement following a minor disciplinary action. Despite a Board of Inquiry’s recommendation that he remain in service, his promotion was later withdrawn—prompting a challenge before the Board for Correction of Naval Records (BCNR), the U.S. District Court for the District of Columbia, and now the D.C. Circuit Court of Appeals.

Attorney Thayer, who will argue on behalf of LT Mitchell, emphasized the broader implications of the appeal:

“This case isn’t only about one officer’s career,” Thayer said. “It’s about ensuring that the military follows its own laws and deadlines and that service members are not punished twice for the same incident. Congress set an 18-month limit on promotion delays for a reason: to guarantee accountability and prevent arbitrary career destruction.”  “It’s also about the plain meaning of the statute.”

The appellant’s brief argues that once the Navy exceeded the statutory delay period, Mitchell was automatically promoted by operation of law, and that the Board for Correction of Naval Records acted arbitrarily and capriciously when it failed to correct this injustice.

The appeal also challenges the Navy’s expansive interpretation of “substandard performance” under MILPERSMAN 1611-020, arguing that no definition of “gross negligence” or “complete disregard of duty” fits the record of an officer consistently rated “Promotable” or “Above Standards” in multiple fitness reports.

Oral argument is scheduled for 9:30 A.M. on November 21, 2025, before a three-judge panel at the E. Barrett Prettyman U.S. Courthouse in Washington, D.C. The outcome could set an important precedent on promotion timelines, executive appointment authority, and due process protections for officers across the armed services.

Navy Officer’s Federal Appeal Challenges Arbitrary Promotion Denial and Career-Saving Records Dispute

Plaintiff Seeks Judicial Review After Navy’s Unjust Delay and Career Impact

A significant appeal has been filed with the U.S. Court of Appeals for the D.C. Circuit challenging the Navy’s prolonged delay and subsequent denial of a career-critical promotion, which the plaintiff argues occurred in direct violation of federal statute. Represented by Dylan Thayer of the Law Offices of David P. Sheldon, PLLC, the plaintiff, a decorated Navy Lieutenant, asserts that the Navy’s Board for Correction of Naval Records acted arbitrarily and capriciously by ignoring mandatory promotion timelines and mischaracterizing his service record.

At the heart of the case is the Navy’s failure to promote the plaintiff within the statutory deadline prescribed by 10 U.S.C. § 624(d)(5), which limits appointment delays to 18 months. The plaintiff’s promotion was delayed nearly 21 months, a violation the Navy itself acknowledged but refused to remedy. Despite exemplary service and a family legacy of military dedication, the plaintiff’s promotion was denied, and he was subjected to an adverse personnel action stemming from a minor 2019 incident aboard the USS Howard, an incident which his command later agreed did not warrant separation from service. The District Court acknowledged the Navy’s statutory breach but held that no enforceable duty existed to promote the plaintiff. The appeal argues this interpretation defies both congressional intent and longstanding precedent affirming the obligation of correction boards to rectify such injustices.

“The Navy delayed this officer’s rightful promotion well beyond what Congress allows,” said Dylan Thayer, lead counsel. “The law is clear: such delays may not exceed 18 months, and when they do, the promotion should occurs by operation of law. Our client’s rights, and his career, have been unjustly compromised.”

The lawsuit also challenges the Navy’s decision to uphold a detachment for cause action, which alleged “gross negligence” despite the plaintiff maintaining a record of exceeding performance standards for much of his career, including multiple commendations.

“This case is not just about one officer’s career,” Thayer added. “It’s about ensuring that service members can rely on the laws Congress enacts to protect them from arbitrary administrative overreach.”

The appeal seeks to overturn the District Court’s ruling and compel the Navy to correct the plaintiff’s record and recognize his promotion as having occurred by operation of law.
