Deleting a text thread, wiping a phone, or clearing a chat history can feel like cleaning up a private device. In the context of a pending or anticipated military investigation, it can also be a crime. Article 131b of the UCMJ, the obstructing justice statute, reaches the destruction of digital evidence directly, and modern courts-martial increasingly turn on exactly this kind of conduct. Understanding how the statute applies to data, rather than to physical documents, is essential for any service member who learns that an investigation is coming.
What Article 131b is
Article 131b, codified at 10 U.S.C. 931b, was created by the Military Justice Act of 2016 and took effect in 2019. It carries forward conduct that had previously been charged as obstruction of justice under the general Article 134. The statute punishes a person who, having reason to believe there are or will be criminal or disciplinary proceedings pending, commits an act with the intent to influence, impede, or obstruct the due administration of justice. Two elements drive the analysis: the existence of proceedings the accused had reason to believe were pending or forthcoming, and a specific intent to obstruct.
Destroying data is “an act” within the statute
Nothing in Article 131b limits obstruction to physical objects. The statute speaks of an act done with the intent to obstruct justice, and destroying, deleting, altering, or concealing evidence is a classic example of such an act. Digital evidence is simply evidence stored electronically: text messages, direct messages on social platforms, emails, photographs, call logs, location data, browser history, files on a laptop, or contents of a cloud account. Deleting any of these, when the other elements are met, fits comfortably within the conduct the statute targets. Wiping or factory-resetting a phone, uninstalling a messaging application to erase its data, removing a memory card, or instructing someone else to delete shared messages are all acts that can support an Article 131b charge.
The pending-or-anticipated-proceedings element
A common misconception is that obstruction only applies once charges are filed. Article 131b is broader. It reaches conduct when the accused had reason to believe that proceedings were pending or would be initiated. That means a service member does not need to have been formally charged, or even formally notified, for the statute to apply. If the circumstances would give a reasonable person reason to believe an investigation is underway or coming, deleting relevant data can qualify. Receiving notice that a command is investigating, being told that law enforcement wants to speak with you, learning that a complaint has been filed, or even being aware that misconduct you participated in is likely to be reported can each supply the requisite reason to believe. The earlier the deletion occurs in relation to that awareness, the more the timing is scrutinized.
The intent element is decisive
The heart of any Article 131b case is intent. The government must prove that the accused acted with the specific intent to influence, impede, or obstruct the administration of justice. Accidental loss, routine and automatic deletion, or innocent housekeeping unconnected to any investigation does not satisfy this element. A phone that auto-deletes messages after thirty days under a setting enabled long before any complaint, or data lost when a device breaks, is not obstruction. What converts deletion into a crime is the corrupt purpose: erasing data because of, and in order to frustrate, an expected or ongoing inquiry. Because intent is rarely admitted, prosecutors prove it circumstantially, through the timing of the deletion relative to the member’s awareness of the investigation, the relevance of the data deleted, statements the member made, and efforts to hide or disguise the act.
How digital deletion is detected and proven
Service members sometimes assume that deleted data is gone for good. That assumption is usually wrong. Forensic examiners working with the Army Criminal Investigation Division, the Naval Criminal Investigative Service, the Air Force Office of Special Investigations, or comparable bodies can frequently recover deleted files, identify when a device was wiped, and detect when an application was removed. Even when the underlying content cannot be recovered, the act of deletion itself often leaves traces, and those traces, paired with evidence the member knew of the investigation, can establish the obstruction. Records held by other parties, such as the other side of a text conversation, server-side copies held by a platform, or backups in a cloud account, can also reconstruct what someone tried to erase. The deletion may end up doing more harm to the accused than the original message would have.
Obstruction can be charged on top of, or instead of, the underlying offense
An important feature of obstruction is that it is independent of the underlying matter. A member can be acquitted of, or never charged with, the offense that prompted the investigation and still be convicted under Article 131b for trying to destroy evidence about it. Obstruction also frequently accompanies related charges, such as making a false official statement under Article 107 or, where another person is induced to delete data, conspiracy under Article 81 or witness tampering concepts within Article 131b itself. The destruction of digital evidence can therefore expand a member’s legal exposure well beyond the original problem.
Consequences
The maximum punishment for obstructing justice under Article 131b includes a dishonorable discharge, forfeiture of all pay and allowances, and confinement for up to five years. Beyond the punitive ceiling, an obstruction conviction signals a deliberate effort to defeat the justice system, which can heavily influence sentencing on any companion charges and can independently end a military career.
The practical lesson
The instinct to delete embarrassing or incriminating messages once an investigation looms is precisely the instinct Article 131b punishes. For a service member who believes an inquiry is pending or coming, the safe course is to preserve devices and data, avoid any deletion, refrain from asking others to delete shared content, and consult qualified military defense counsel before taking any step. Counsel can advise on rights and on lawful conduct, whereas a hasty wipe can transform a defensible situation into a separate, provable felony-level offense. In the digital era, the cover-up is often easier to prove than the original conduct, and Article 131b is the article that proves it.

Military law also changes over time.
