Navy-Marine Corps Court of Criminal Appeals

The Navy-Marine Corps Court of Criminal Appeals (NMCCA) is the intermediate appellate court for criminal convictions in the United States Navy and the Marine Corps.

Courts-martial are conducted under the Uniform Code of Military Justice (Title 10 of the United States Code §§ 801-946), and the Manual for Courts-Martial. If the trial results in a conviction, the case is reviewed by the convening authority (the person who referred the case for trial by court-martial). The convening authority has discretion to mitigate the findings and sentence.

If the sentence, as approved by the convening authority, includes death, a bad conduct or dishonorable discharge, dismissal of an officer, or confinement for one year or more, the case is reviewed by an intermediate court. For the Navy and Marine Corps, this is the Navy-Marine Corps Court of Criminal Appeals.

The Navy-Marine Corps Court of Criminal Appeals (NMCCA) is located in Washington, D.C. in the Navy Yard. The court conducts mandatory review (unless waived by the appellant) of all courts-martial of members of the naval service referred to the court pursuant to Articles 62, 66, 69, and 73 of the Uniform Code of Military Justice. When necessary in furtherance of its jurisdiction, the Court reviews all petitions for extraordinary relief properly filed before it (28 U.S.C. § 1651). The United States military justice system commonly uses four writs: mandamus, prohibition, error coram nobis, and habeas corpus. A writ of mandamus is an order from a court of competent jurisdiction that requires the performance of a specified act by an inferior court or authority. The writ of prohibition is used to prevent the commission of a specified act or issuance of a particular order. The writ of error, coram nobis, is used to bring an issue before the court that previously decided the same issue. It allows the court to review error of fact or a retroactive change in the law that which affects the validity of the prior proceeding. The writ of habeas corpus is used to challenge either the legal basis for or the manner of confinement.
