Short answer: The records list 11 courts-martial at Mayport, Florida in 2022, down from 24 in 2021. Contested cases made up 64% of those with a plea recorded, compared with 33% across the Navy and Marine Corps. Full acquittals came in 3 of the 7 contested cases that reached a verdict.
Most Accused Contested at Least One Charge
Of the 11 cases, 7 had a not-guilty or mixed plea and 4 had a guilty plea. That is a contested share of 64%. Across all Navy and Marine Corps cases in 2022, the contested share was 33%.
A case counts as contested when the accused pleads not guilty to at least one charge. A mixed plea, guilty to some charges and not guilty to others, also counts as contested.
Full Acquittals and Sentences
Of the 7 contested cases that reached a verdict, 3 ended in a full acquittal, meaning not guilty of all charges. In 2021 the figure was 2 of 10.
Confinement was part of 6 of the 8 convictions. The median confinement was 5 months, compared with 1.5 years in 2021. These are adjudged sentences, set at trial before any plea-agreement cap, clemency, or appeal.
Among the 8 convicted enlisted members, 4 received a punitive discharge. A punitive discharge is a bad-conduct or dishonorable discharge. A sentence without one does not rule out a later administrative separation.
Article 80 Was the Most Common Charge
Charges are listed for all 11 cases. Attempts under Article 80 appeared in 3 cases (27%), compared with 6% across the Navy and Marine Corps. Article 109 (property other than military; waste, spoilage, destruction) appeared in 2 cases (18%), compared with 1% service-wide.
Article 134, Article 92, and Article 112a each appeared in 2 cases (18%). Assault under Article 128 appeared in 1 case (9%), lower than the 23% across the service. A case with several articles is counted under each one.
