Article 92 of the Uniform Code of Military Justice, codified at 10 U.S.C. 892, punishes failure to obey orders and regulations. Whether the Government must prove that the accused actually knew of the order, or whether some lesser form of awareness suffices, depends entirely on which type of violation is charged. The phrase constructive knowledge captures the idea that a person is treated as knowing something they should have known, even without direct proof that they actually knew it. In the Article 92 setting, constructive knowledge plays a meaningful role for some theories of liability and almost none for others. Sorting out where it matters is the heart of understanding this offense.
The three theories of liability under Article 92
Article 92 reaches three distinct kinds of misconduct. The first is violation of, or failure to obey, a lawful general order or regulation. The second is failure to obey other lawful orders, meaning orders that do not qualify as general orders or regulations. The third is dereliction in the performance of duties. The knowledge requirement differs across these theories, so the first analytical step in any case is to identify which theory the Government has charged.
General orders and regulations: knowledge is presumed
For a violation of a lawful general order or regulation, the Government does not have to prove that the accused actually knew of the order or regulation. Knowledge is not an element of this theory. Service members are charged with knowledge of all properly published general orders and regulations within their command, and lack of knowledge is not a defense. This is the purest expression of constructive knowledge in Article 92: the law conclusively presumes that the member knew the general order because it was properly issued and published, and the member is responsible for being aware of it.
The premise behind this presumption is that general orders and regulations apply broadly across a command or service, are issued by senior authority, and are disseminated through official channels. Because every member is expected to know them, the prosecution is relieved of proving individual awareness. For the defense, this means challenging actual knowledge is futile on this theory. The productive lines of attack instead focus on whether the order truly qualifies as a general order or regulation, whether it was properly published and in effect, whether it is lawful, and whether the accused’s conduct actually violated its terms.
Other lawful orders: actual knowledge is required
The analysis is different for the second theory, failure to obey other lawful orders. For these orders, which are narrower than command-wide general orders, the accused must have actual knowledge of the order. The prosecution must prove that the member in fact knew of the order, whether it was given verbally or in writing. Here, constructive knowledge in the sense of a conclusive presumption does not apply. A member who genuinely did not know of a specific order that was not a general order or regulation has a real defense on the knowledge element.
This is where disputes about notice typically arise. Prosecutions under Article 92 often turn on whether the accused had actual or constructive notice of the particular order. Because actual knowledge is required for the other-orders theory, the Government proves knowledge through circumstantial evidence: that the order was briefed in a formation the member attended, that the member signed for or acknowledged it, that it was posted where the member worked, or that the member’s conduct showed awareness of it. The fact finder may infer actual knowledge from such circumstances. That inference, drawn from facts that make knowledge highly likely, is sometimes loosely described as constructive notice, but the ultimate question remains whether the member actually knew. Strong circumstantial proof can establish actual knowledge, while the mere theoretical availability of the order, without more, may not.
Dereliction of duty and a different kind of notice
The dereliction theory introduces yet another standard. A member can be derelict willfully, through negligence, or through culpable inefficiency in performing known duties. The relevant awareness here concerns the duty rather than a written order. A member must have known of the duties, and dereliction can rest on negligence in performing them. This is conceptually distinct from the constructive-knowledge presumption that applies to general orders, and counsel should be careful not to blur the two, because the elements and defenses differ.
Why the distinction drives the case
The practical upshot is that the role of constructive knowledge depends on the charging theory. If the Government charges violation of a general order or regulation, it sidesteps the knowledge question entirely through the presumption, and the litigation centers on the order’s validity, scope, publication, and the conduct alleged. If the Government charges failure to obey another lawful order, knowledge is squarely in play, and both sides litigate whether the member actually knew, often through circumstantial evidence of notice. Mischarging can be consequential. Treating a specific order as if it were a general order, in order to invoke the presumption and avoid proving knowledge, is a recognizable error that the defense can expose.
How the defense approaches knowledge
A defense team begins by pinning down exactly what the Government has charged and under which theory. On a general-order theory, the defense examines whether the directive is genuinely a general order or regulation, whether it was lawfully issued and properly published, whether it remained in effect, and whether the conduct fell within its terms, because actual knowledge cannot be contested. On an other-orders theory, the defense scrutinizes the proof of knowledge, testing whether the circumstantial evidence really establishes that the member knew of the specific order, and whether any acknowledgment, briefing, or posting actually reached the accused.
In short, constructive knowledge in an Article 92 prosecution is best understood as a feature of the general-order theory, where the law presumes that properly published general orders and regulations are known to all members and lack of knowledge is no defense. For other lawful orders, the Government must prove actual knowledge, although it may do so with circumstantial evidence of notice. Because the knowledge analysis turns on these distinctions, service members facing an Article 92 charge should work with qualified defense counsel to identify the precise theory charged and to build the defense the elements actually allow.
