An acquittal at a court-martial is supposed to mean vindication. So it is jarring when, soon after being found not guilty, a service member receives notice that the command is initiating an administrative discharge based on the very same conduct. Many members assume an acquittal bars any further action, invoking double jeopardy. That assumption is largely mistaken in this context, but it does not mean the member is powerless. A discharge initiated after an acquittal can be contested, and there are strong arguments available, even though the acquittal itself does not legally block the administrative process.
Why double jeopardy usually does not bar the discharge
Double jeopardy protection in the military comes from the constitutional guarantee and from Article 44 of the Uniform Code of Military Justice, which prevents a second trial by court-martial for the same offense after a final acquittal or conviction. The crucial point is that this protection operates within the criminal justice system. It bars a second criminal prosecution. It does not bar administrative actions, because administrative separation is not a criminal proceeding and does not place the member in jeopardy in the constitutional sense.
As a result, a command may pursue administrative separation, security clearance action, or other administrative consequences arising from the same conduct that produced an acquittal. The member who hoped the not-guilty verdict ended the matter must understand this structural reality: the two systems run on different tracks, with different purposes and different burdens.
The different burden of proof
The reason an acquittal does not control the administrative outcome lies in the burden of proof. A court-martial acquittal means the government failed to prove guilt beyond a reasonable doubt. An administrative separation board, by contrast, decides whether the basis for separation is established by a preponderance of the evidence, meaning more likely than not. A member can be acquitted because the evidence fell short of the high criminal standard yet still face separation if the same evidence satisfies the lower administrative standard. This is not double counting in the legal sense; it reflects that the two forums ask different questions.
What the member can still contest
Although the acquittal does not bar the action, it is far from worthless, and several avenues remain open. First, the member is generally entitled to a separation board or board of inquiry, depending on the length of service and characterization at stake, with the right to …
