Many Article 120 cases under the Uniform Code of Military Justice arise between people who already knew each other and who had a prior consensual relationship. A common assumption is that a history of consensual contact between the accuser and the accused settles the matter, or at least that the defense can freely tell the members about it. Neither is true. Prior consensual contact can be legally significant, but how it may be used is controlled by specific rules, and a past relationship never establishes consent to a later encounter. This article explains how military law treats prior consensual contact in an Article 120 prosecution.
Consent Is Decided For The Charged Encounter
The first principle is that Article 120 focuses on whether there was consent to the specific act charged. Consent must exist for that encounter, and it can be withdrawn at any time. A prior relationship, even an ongoing and recent one, does not create standing permission for future contact. The fact that two people were once intimate, or were intimate the day before, does not by itself answer the question the members must decide about the charged event.
This is why the government can and does prosecute cases between spouses, dating partners, and former partners. The existence of a relationship is not a defense in itself. What matters legally is consent at the time of the charged conduct, judged in light of all the circumstances.
How The Rape Shield Rule Treats Prior Contact
Evidence about an alleged victim’s sexual behavior is governed by Military Rule of Evidence 412, the military rape shield rule. Its default is exclusion. Evidence offered to prove that an alleged victim engaged in other sexual behavior, or to prove a sexual predisposition, is generally not admissible.
The rule does, however, recognize a specific exception for sexual behavior between the alleged victim and the accused. Evidence of specific instances of such behavior may be admissible when offered by the defense to prove consent, or when offered by the prosecution. This is the exception most relevant to a case involving prior consensual contact between the parties. It reflects the reality that the nature of a prior relationship between the two people involved can bear on the question of consent in a way that a complaining witness’s unrelated sexual history does not.
The Exception Is Not Automatic
It is a mistake to think this exception lets the defense parade the entire history of the relationship before the members. The exception is a doorway, not an open field. Even when evidence concerns prior behavior between the accuser and the accused, it must still be relevant to a fact at issue, and the military judge weighs its value against the danger of unfair prejudice. The judge can admit some instances while excluding others, and can limit how the evidence is presented.
Just as important, the evidence must come through the rule’s procedure. A party seeking to introduce prior contact must file a written motion that specifically describes the evidence and the purpose for which it is offered, ordinarily before trial within the time set by the rule. The judge holds a closed hearing, hears from the parties and may hear from the alleged victim, and only then rules. Counsel who simply attempts to raise the prior relationship during cross-examination without following this process risks having the evidence excluded entirely.
What Prior Contact Can And Cannot Do
Used properly, evidence of a prior consensual relationship may help the defense provide context for the charged encounter, may bear on the reasonableness of any belief about consent, and may be part of a broader credibility picture. It can show that the interaction did not arise out of nowhere and can frame how the parties communicated and behaved.
What it cannot do is substitute for consent to the charged act. The members will be instructed that a current or previous relationship does not by itself constitute consent, and that consent must exist for the specific conduct at issue. The defense theory must therefore connect the prior contact to the charged event in a way that is logically relevant, rather than inviting the members to infer that a person who consented before must have consented again.
Practical Considerations For The Accused
For a service member accused under Article 120 where there was a prior consensual relationship, several practical points follow. The relationship should be documented and discussed candidly with defense counsel, including any messages, communications, or other evidence that reflect its nature. Counsel must evaluate early which instances of prior contact might be admissible and prepare a precise motion under the rape shield rule, since the procedure is strict and the window can be short. The defense must also be ready for the government’s argument that the past relationship is irrelevant to consent on the charged occasion.
A prior consensual relationship is a meaningful piece of the picture, but it is neither a shield nor a shortcut. It is evidence that must be developed carefully and admitted through the proper channel. Because the rules are technical and the stakes are high, a service member in this situation should rely on an experienced military defense attorney to determine how prior consensual contact can be used effectively and lawfully in the defense.
