Disobeying an order is one of the most serious charges a service member can face, prosecuted under articles such as Article 90 of the UCMJ for willfully disobeying a superior commissioned officer and Article 92 for failure to obey a lawful order or regulation. A recurring and difficult question is what happens when the accused refused or failed to comply because he believed the order was unlawful. The available defenses turn on a crucial distinction in military law: an order that is actually unlawful is one thing, while a sincere but mistaken belief that a lawful order was unlawful is another. Both situations matter, but they lead to different defenses.
The Presumption That Orders Are Lawful
Military law begins with a presumption that orders are lawful. An order is presumed lawful and is disobeyed at the subordinate’s peril. This presumption exists because the armed forces cannot function if every service member could second-guess every instruction. To remain within the presumption, an order must relate to military duty and must not conflict with the statutory or constitutional rights of the person receiving it. A lawful order must also be reasonably specific and must not be issued merely to harass or humiliate. The presumption is strong, but it is not absolute.
The Strongest Defense: The Order Actually Was Unlawful
The most direct defense is to show that the order was, in fact, unlawful. Unlawfulness is a complete defense to a charge under Article 90 or Article 92, because there is no offense in refusing to obey an order the law itself does not require you to follow. An order can be unlawful for several reasons. It may direct the commission of a crime. It may conflict with the Constitution or a federal statute. It may invade the recipient’s statutory or constitutional rights. It may be unrelated to any military duty, or it may be so vague or overbroad that it cannot stand. Orders given solely to harass or humiliate also fall outside the scope of lawful authority.
A particularly clear category is the manifestly unlawful order. Service members are not only permitted but required to refuse orders that are clearly illegal on their face, such as an order to commit an atrocity that violates the law of armed conflict. When the order falls into this category, refusing it is not misconduct at all. If the defense can establish actual unlawfulness, the prosecution’s …
