Consent sits at the center of most sexual misconduct prosecutions under the Uniform Code of Military Justice. Article 120 of the UCMJ, codified at 10 U.S.C. 920, supplies a statutory definition that controls how military judges and panels evaluate whether an alleged sexual act or sexual contact was lawful. Understanding that definition is essential because the presence or absence of consent often determines whether conduct is criminal at all.
The Statutory Definition of Consent
Article 120 defines consent as a freely given agreement to the conduct at issue by a competent person. The phrase carries weight in each of its parts. The agreement must be freely given, meaning it cannot be the product of force, threat, or fear. It must be an agreement to the specific conduct at issue rather than a general willingness to be in someone’s company. And it must come from a competent person, meaning someone with the present capacity to understand and agree to what is happening.
This definition is deliberately framed around the conduct in question. A person who agrees to one act has not necessarily agreed to another, and agreement at one moment does not lock a person into agreement that continues indefinitely.
What the Statute Says Does Not Establish Consent
Much of the practical content of Article 120 lies in the circumstances the statute expressly excludes from the meaning of consent. The law states that an expression of lack of consent through words or conduct means there is no consent. It also makes clear that a lack of verbal or physical resistance does not by itself constitute consent. This rejects the older intuition that a person must fight back or say no in a particular way for the encounter to be non-consensual.
The statute further provides that submission resulting from the use of force, threat of force, or placing a person in fear does not amount to consent. Yielding under pressure is not agreement. Article 120 also specifies that a current or previous dating, social, or sexual relationship, standing alone, does not constitute consent, and neither does the manner of a person’s dress. These provisions remove from the courtroom several arguments that historically clouded sexual misconduct cases.
Capacity and the Limits of Consent
Article 120 ties consent to competence. A sleeping, unconscious, or otherwise incompetent person cannot consent. The statute also recognizes that a person cannot consent to force likely to cause death or grievous bodily harm, nor to being rendered unconscious. These limits mean that even apparent agreement carries no legal effect when the person lacks the capacity to give it or when the conduct exceeds what any agreement could authorize.
Capacity questions frequently arise in cases involving alcohol or other intoxicants. Article 120 addresses this directly through its sexual assault provisions. A person commits sexual assault by committing a sexual act upon another who is incapable of consenting because of impairment by a drug, intoxicant, or similar substance, when that condition is known or reasonably should be known. The same framework applies when the incapacity arises from a mental disease or defect or a physical disability that is known or reasonably should be known. The standard is not simply whether the other person had been drinking but whether the level of impairment removed the ability to consent.
How Consent Functions at Trial
In a court-martial, the government bears the burden of proving every element beyond a reasonable doubt. Where the charged offense requires the absence of consent, or where the accused raises consent as a defense, the practical question for the panel becomes whether the evidence shows a freely given agreement by a competent person to the specific conduct at issue. The statutory exclusions guide that inquiry by telling the panel what cannot be treated as agreement.
Because consent is judged against the conduct at issue, the analysis is fact specific. Panels weigh testimony about words exchanged, the surrounding circumstances, the relative states of the people involved, and any indicators of capacity or its absence. The definition in Article 120 channels that weighing toward the central question of whether genuine, capable agreement existed.
Why the Definition Matters for Service Members
For a service member facing an allegation, the statutory definition shapes both exposure and defense. The exclusions mean that arguments resting on a prior relationship, a person’s clothing, or the absence of resistance will not carry the day on their own. At the same time, the requirement that consent be freely given and that the other person be competent provides the framework within which a defense built on genuine mutual agreement is presented. The definition is not a formality. It is the legal standard against which the entire encounter is measured.
Article 120 has been amended several times, and its provisions continue to be interpreted by military appellate courts. Anyone confronting a sexual misconduct allegation should understand that the consent inquiry is governed by this precise statutory language rather than by general assumptions, and that the specific facts will be measured against it element by element.

Military law also changes over time. The Military Justice Act of 2016 (effective January 1, 2019) and subsequent National Defense Authorization Acts renumbered and rewrote many punitive articles, revised the Article 32 preliminary hearing, and altered sentencing, clemency, and appellate procedures.
