Mullan v. United States

Background

Dennis W. Mullan, a Navy commander serving as commandant at the Pensacola navy yard, faced charges of drunkenness and drunkenness on duty. At his request a court of inquiry investigated and reported adversely. He asked for a court-martial; the Navy agreed to try him if the court-of-inquiry record could be used and each side could call other witnesses. Mullan accepted those conditions but sought the extra rights to recall prior witnesses and take depositions; the Secretary refused those requests. At the court-martial the inquiry record and one additional witness were used. The court-martial convicted him, the Secretary approved dismissal, and the President on July 8, 1897 confirmed but mitigated the punishment to reduction in rank, suspension with half sea pay for five years. Mullan sued to recover the pay difference for that period.

Reasoning

The core question was whether Mullan could treat the court-martial as void because the trial relied on the court-of-inquiry record in a case that could lead to dismissal—something the statute otherwise limited. The Court held that Mullan had waived any statutory protection by agreeing to the terms and not objecting at trial. The opinion explained that where no constitutional mandate or public policy forbids it, an accused may waive procedural rights. The Court also found the court-martial was properly organized and had given Mullan an opportunity to introduce witnesses. As to the President’s action, the Court treated the President’s change as mitigation—lessening the punishment—which was lawful.

Real world impact

The ruling leaves the court-martial conviction and the President’s mitigation in place and affirms the denial of Mullan’s pay claim. It means service members can consent to use of prior inquiry records and thereby lose a later ground for civil relief. The decision also affirms that a President may legally lessen a military sentence in the manner described.
