Pretrial confinement is one of the most serious forms of restraint a service member can face before any finding of guilt. Because it deprives a person of liberty while charges are still pending, military law surrounds it with a series of mandatory reviews and standards designed to ensure the confinement is justified and remains justified over time. These protections come primarily from Rule for Courts-Martial 305 and from Article 13 of the Uniform Code of Military Justice. Together they create a layered system of timed reviews, a governing probable cause standard, and remedies when the rules are not followed.
The Foundational Standard: Probable Cause and Necessity
No service member may be placed into pretrial confinement unless probable cause exists. Probable cause in this setting requires a reasonable belief that an offense triable by court-martial has been committed, that the person to be confined committed it, and that confinement is required by the circumstances. That last element is critical. It is not enough that the member is suspected of an offense; the government must also show that confinement, as opposed to a lesser form of restraint, is necessary. The recognized justifications generally center on ensuring the member’s presence at trial and preventing serious criminal misconduct, and on the absence of less restrictive alternatives that would reasonably accomplish those goals.
This necessity requirement is itself a due process protection. It prevents confinement from being used reflexively or punitively and forces decision makers to justify why nothing short of confinement will do.
The Layered Review Timeline
The defining feature of military pretrial confinement is its schedule of mandatory reviews, each performed by a different actor and serving a distinct function.
Within 48 hours of confinement, a neutral and detached officer must review whether probable cause supports the confinement. This early review echoes the constitutional requirement for a prompt probable cause determination after a seizure and ensures that someone independent looks at the basis for confinement quickly.
Within 72 hours, the member’s commander must decide either to direct release or to prepare a written memorandum explaining why continued pretrial confinement is warranted. This step forces a documented command-level justification rather than an open-ended detention.
Within 7 days of the imposition of confinement, a neutral and detached officer who is independent of the command, such as a military magistrate, must conduct a more thorough review of both the probable cause determination and the necessity for …
