Military life runs on written guidance: regulations, instructions, standard operating procedures, and local policy letters. When that guidance is not updated and a service member follows the old version, a charge can follow even though the member did exactly what the most recent document on hand told them to do. Several defenses may apply, and most of them attack the core elements the government must prove rather than asking for forgiveness after the fact. The analysis usually unfolds under Article 92 of the Uniform Code of Military Justice, 10 U.S.C. 892, which covers violations of orders and regulations and dereliction of duty.
Attack the elements first
The strongest position is often that the government cannot prove a required element. Under Article 92, the prosecution must establish a lawful order or regulation and, depending on the theory, the member’s knowledge of it. If a unit failed to publish or disseminate a superseding policy, the member may never have had actual knowledge of the new rule. For “other lawful order” theories, actual knowledge is required, so a gap in dissemination can be fatal to the charge. Even for general regulations, where knowledge is presumed, a defense can argue that the conduct complied with the regulation as it was actually issued and in effect, not with an unpublished revision.
Reliance on an authorized official or pronouncement
Rule for Courts-Martial 916 states the general principle that ignorance or mistake of law, including ignorance of a regulation, is ordinarily not a defense. But it contains an important exception: the defense applies when the mistake results from reliance on the decision or pronouncement of an authorized public official or agency. A service member who followed guidance that was the official, on-file policy, or who was directed to that guidance by someone with authority to interpret or issue it, can fall squarely within this exception. The point is not that the member misunderstood the law on their own, but that the institution itself, through its authorized channels, told the member that the outdated procedure was the governing one.
Mistake of fact
Separate from mistake of law, a member may have an honest and reasonable mistaken belief about the facts. If the member reasonably believed the document they were following was current and authoritative, that belief can negate the mental state required for many Article 92 theories. For dereliction of duty, the government must prove the member was willfully, negligently, or culpably inefficient. A member who diligently consulted the official guidance available and reasonably relied on it is hard to characterize as negligent or willfully derelict, because they took the very step the system expects of a careful service member.
No willful or negligent dereliction
Where the charge is dereliction of duty, the defense can focus on the absence of fault. The duty must be known or reasonably knowable, and the failure must be culpable. If the failure to follow current policy traces back to the command’s lapse in updating and distributing that policy, the culpability lies with the organizational process, not the individual who acted in good faith on the materials provided. Demonstrating that the member checked the appropriate references, asked the right questions, or followed local training that itself reflected the outdated guidance can dismantle the negligence theory.
The order or regulation was not lawful or applicable
A regulation is presumed lawful, but the defense can argue that the version the government claims was violated was not properly in effect, was internally contradictory because of the failed update, or did not clearly apply to the member’s situation. When two versions of guidance circulate because of a botched update, ambiguity about which rule governed at the relevant time can prevent the government from proving a clear, applicable, lawful directive. Ambiguity in what was actually required cuts against a finding of guilt.
Evidence to gather
Defenses in these cases live or die on documentation. Counsel will want the specific guidance the member relied on, with version dates and effective dates, the publication and distribution history of the superseding policy, any training records or briefings that reinforced the old procedure, and communications showing who directed the member to which document. Records establishing that the new policy was never properly promulgated or pushed to the unit are especially valuable, because they shift responsibility for the gap onto the command’s administrative process.
Mitigation if liability remains
If a violation cannot be fully defeated, the same facts strongly support extenuation and mitigation. Good-faith reliance on the only guidance reasonably available, the absence of any intent to evade the rules, and a clean record of otherwise diligent compliance all weigh heavily in favor of minimal or no punishment, including resolution short of court-martial.
Bottom line
Following outdated guidance because the command failed to update its policies is not a guaranteed shield, but it opens several genuine avenues: lack of knowledge, the RCM 916 reliance exception, mistake of fact, absence of culpable dereliction, and ambiguity about which rule was actually in force. Because each defense depends on precise dates, distribution records, and the exact text of competing versions, a member in this position should preserve every relevant document and consult military defense counsel promptly.

Military law also changes over time.
