Mistake of fact as to consent is misunderstood in both directions: overstated by people who think it is available whenever the accused says they thought there was consent, and dismissed by people who think it never works.
Both readings do damage. The first produces service members who talk to investigators because they believe their explanation is itself the defense. The second produces cases where the instruction is never sought. Joseph L. Jordan, Attorney at Law has tried 181 Article 120 courts martial, and this defense is neither automatic nor unavailable: it is earned by evidence in a specific way, and it is lost in a specific way.
What the Defense Actually Requires
The requirement is more demanding than most descriptions of it suggest, and it varies with the offense charged. Mr. Jordan served as an Army prosecutor before opening his own practice, and the government’s answer to this defense is prepared long before trial. Any statement the accused has given is part of the material it is built from.
The defense is not simply that the accused believed there was consent. What it requires depends on the offense charged, and that dependency is the part most often stated wrong.
Under R.C.M. 916(j), the mistake must always be honest, meaning genuinely held rather than constructed after the fact. Whether it must also be reasonable turns on the mental state the charged offense requires:
- For a general intent offense, the mistake must be both honest and objectively reasonable under all the circumstances.
- For an offense requiring a specific intent or actual knowledge, an honest mistake can defeat the required mental state even if it was not reasonable, because the question is whether the accused actually formed the intent the offense requires.
Under Article 120, which mental state applies depends on the specification. Some theories require that the accused knew or reasonably should have known of a condition; others are framed differently. This is why the first question in evaluating this defense is not “did he believe there was consent” but “what does this specification require the government to prove about his state of mind.”
That analysis determines what your attorney has to establish and what the military judge will instruct the members.
Where the Line Falls on Intoxication
This is where most of the confusion sits.
The military judge’s instructions turn on how the offense is charged. Where a charged offense requires a specific intent, evidence of the accused’s own voluntary intoxication may be relevant to whether that intent was formed. Where the offense is one of general intent, voluntary intoxication by the accused does not excuse the conduct, and a mistake of fact must still be objectively reasonable.
A separate question is the complaining witness’s condition. Article 120 addresses situations in which a person is incapable of consenting. Whether the accused knew or reasonably should have known of that incapacity is the contested ground, and it is contested on evidence: what the accused observed, what others observed, and what the accused did in response.
What the Defense Is Not
It is not a claim that a person who was intoxicated is therefore capable of consenting.
It is not a claim that prior sexual history between the parties supplies consent on a later occasion. Military Rule of Evidence 412 restricts the admissibility of a complaining witness’s sexual behavior and predisposition, with narrow exceptions that require a written motion and a closed hearing before anything is offered.
It is not a claim that the absence of resistance is consent.
None of those framings is a defense, and pressing one of them in front of a panel costs the accused credibility at exactly the moment credibility matters most, including at sentencing if it comes to that.
What Actually Determines Whether the Instruction Is Given
Whether a panel ever hears this instruction is decided by the military judge, on the evidence actually before the court, and it is decided late. This firm defends Article 120 allegations in all six branches, and the point holds throughout: the instruction follows evidence rather than argument, so the work of earning it begins during the investigation and not at trial.
A defense reaches the members only if the military judge finds some evidence in the record to support it. That means the work happens before argument, in what the record contains:
- Contemporaneous communications between the parties
- Observations by third parties about the complaining witness’s condition and behavior over the relevant period
- What the accused said at the time and immediately afterward
- Expert testimony, where it is warranted, about intoxication and memory
Where the record supports the instruction, the judge gives it and the government carries the burden of disproving the mistake beyond a reasonable doubt. Where it does not, the theory never reaches the panel.
Why This Matters Before Trial
An accused who believes this defense is automatically available tends to talk, because they think their explanation is the defense. It is not. The explanation is evidence, and it is evidence the government also gets to use. Mr. Jordan prosecuted cases built on statements of that kind before he entered private practice as a defense attorney. A defense is hardest to adjust when an important fact reaches counsel late, and an early statement is one of the ways that happens.
The evidence that supports or defeats this defense is generated in the first days after an allegation, and much of it is perishable. By the time a case is referred, messages have been deleted and recollections have hardened.
If you are under investigation, the decisions that determine whether this defense is available to you are being made now, not at trial.

Where consent and the accused’s state of mind are the contested issues, the outcome turns on the record. Results include an Article 120 acquittal for an Army captain at Fort Hood and a not guilty verdict on a wrongful sexual contact charge.
Past results do not guarantee future outcomes. Every case turns on its own facts.
