How Does the U.S. Military Justice System Compare to Civilian Federal Criminal Courts?

The two systems differ at almost every stage. Court-martial jurisdiction depends on the accused’s military status (Solorio v. United States, 1987); a federal court’s depends on a federal criminal statute. Felony charges in federal court need a grand jury indictment, while the Fifth Amendment excepts “cases arising in the land or naval forces,” and an Article 32 preliminary hearing screens charges before a general court-martial. A federal jury “consists of 12 persons unless this rule provides otherwise” and must be unanimous (Fed. R. Crim. P. 23(b), 31(a)); a court-martial panel has 8 members (12 in a capital case, 4 at a special court-martial) and convicts by three-fourths, with unanimity required only for a death sentence (Article 52). Appeals run to the Court of Criminal Appeals and CAAF rather than a regional court of appeals (how the military appellate court system functions).

Jurisdiction

In Solorio v. United States, 483 U.S. 435 (1987), the Court held that court-martial jurisdiction does not depend on “the ‘service connection’ of the offense charged” and overruled O’Callahan v. Parker. A member on active duty may be court-martialed for an off-duty, off-base offense; a federal court can try the same person only if a federal statute reaches the conduct. The bases of military jurisdiction are covered in the legal basis for court-martial jurisdiction.

Charging

The Fifth Amendment requires a grand jury for a capital or otherwise infamous crime, “except in cases arising in the land or naval forces”. For a general court-martial, the substitute is the Article 32 preliminary hearing, which is public by default, which the accused attends with counsel, and which produces an advisory report; the referral decision then belongs to the convening authority or, for covered offenses committed after December 27, 2023, to a special trial counsel, whose referral binds the convening authority (Articles 24a(c), 32, 34). See the Article 32 preliminary hearing.

The factfinder and the vote

Panel selection. Members are detailed by the convening authority as “best qualified” under Article 25(e)(2), and for courts-martial convened on or after December 23, 2024, the military judge randomizes the panel from a larger pool; see how panel members are selected.

The vote. “No person may be convicted of an offense in a general or special court-martial, other than” after a guilty plea, by a military judge alone, or “by the concurrence of at least three-fourths of the members present when the vote is taken” (Article 52(a)). That rule applies in capital cases too. A death sentence, however, requires “a unanimous finding of guilty of an offense in this chapter expressly made punishable by death and … a unanimous determination by the members that the sentence for that offense shall include death” (Article 52(b)(2)). A capital case with a three-fourths but not unanimous guilty vote can end in conviction, but not in death.

No Sixth Amendment jury. In United States v. Anderson, No. 22-0193 (C.A.A.F. June 29, 2023), CAAF held that court-martial defendants have no right to a unanimous verdict “under the Sixth Amendment, the Fifth Amendment Due Process Clause, or the Fifth Amendment component of equal protection”; see the constitutional rights a servicemember retains.

Questioning and counsel

Article 31(b) requires a warning before anyone subject to the UCMJ, acting in an official law-enforcement or disciplinary capacity, interrogates or requests a statement from a suspect, whether or not the suspect is in custody, and detailed military defense counsel are provided at general and special courts-martial without regard to ability to pay. The details are in the Article 31 warning and Miranda and the right to counsel in court-martial proceedings.

Sentencing and appeal

For non-capital cases in which all findings of guilty are for offenses committed after December 27, 2023, a military judge sentences under the sentencing parameters; earlier cases may have been sentenced by members at the accused’s election. Appeals go to the service Court of Criminal Appeals, then CAAF, then the Supreme Court by certiorari.
