Background
In January 2022, Great Falls police responded to a neighbor’s report of a violent disturbance at an apartment. Officers found Sebastian Belcourt at the door with dried blood on his hands. The victim, R.A., with whom Belcourt had been in a six-year intimate relationship, presented with a deep gash on her chin, facial swelling and scratches, and redness on her neck. Once separated from Belcourt, R.A. described a three-day escalation of domestic violence that included Belcourt punching out a car window and striking her with glass, grabbing her throat while she slept beside their infant daughter until she lost consciousness, striking her nose repeatedly with his knee, and a second strangulation that caused her to lose consciousness before he threw her into a lamp. R.A. fled to a laundry room dryer; Belcourt found her, dragged her back by the hair, and threatened her life.
The State charged Belcourt with strangulation of a partner or family member, unlawful restraint, assault on a peace officer, and resisting arrest. Before trial, Belcourt moved to introduce evidence of R.A.’s alleged activity on two adult websites — Fansly (a subscription adult-content platform) and FetLife (a social network oriented toward BDSM interests) — to support his defense that he grabbed R.A.’s throat to sexually arouse her, not to impede her breathing, and therefore lacked the mental state required by the strangulation statute. Notably, strangulation did not appear as a listed interest in the proffered exhibits from those accounts.
The District Court denied the motion in limine under Mont. R. Evid. 403, finding the internet history evidence minimally probative because it showed no interest in strangulation specifically, while posing a substantial risk of unfair prejudice to R.A. and confusion of the issues. The court permitted Belcourt to cross-examine R.A. on whether she had ever communicated to him an interest in strangulation or previously consented to or shown arousal during strangulation. A jury convicted Belcourt on the strangulation, unlawful restraint, and resisting arrest charges, and the court imposed a five-year state prison sentence plus two six-month county detention terms. Belcourt appealed.
The Court’s Holding
The Montana Supreme Court unanimously affirmed, holding that the District Court did not abuse its discretion when it excluded evidence of R.A.’s internet history under Rule 403. The Court reasoned that because Belcourt’s defense theory was that he strangled R.A. to arouse her — not to impede her breathing — only evidence bearing on his knowledge that R.A. had an interest in strangulation was relevant. R.A.’s alleged interest in collars, restraints, submission, and other BDSM acts had no tendency to make it more probable that Belcourt knew she consented to strangulation specifically, and the proffered exhibits did not even list strangulation as an interest.
The Court further rejected Belcourt’s Confrontation Clause challenge. While the Sixth Amendment and the Montana Constitution guarantee a defendant the right to cross-examine adverse witnesses, that right extends only to an opportunity for effective cross-examination, not to cross-examination in whatever form or to whatever extent the defense wishes. The District Court preserved that opportunity by expressly permitting Belcourt to question R.A. about any prior communication or manifestation of consent to strangulation. Because Belcourt was not denied a meaningful chance to present his defense, no constitutional violation occurred.
The Court also rejected Belcourt’s claim of structural error. Structural error is reserved for fundamental defects that undermine the trial framework itself; an evidentiary ruling under Rules 401 and 403 that leaves the core defense theory available for development does not qualify. The Court also declined Belcourt’s implicit equivalence between a legislatively designated felony and consensual, nonconventional sex acts, calling the comparison legally and factually inapt.
Key Takeaways
- Under Mont. R. Evid. 403, a victim’s general interest in unconventional sex acts is not relevant to a strangulation charge when the proffered evidence does not establish the defendant’s knowledge that the victim specifically consented to strangulation.
- The Confrontation Clause guarantees an opportunity for effective cross-examination, not unlimited cross-examination; a court may confine questioning to matters genuinely relevant to the defendant’s theory without violating the Sixth Amendment.
- A trial court’s targeted evidentiary limitation that still preserves the defendant’s ability to pursue the core defense theory does not constitute structural error.
- Courts may properly consider that evidence introduced to negate mental state risks placing the victim on trial for her private sexual interests where those interests are not directly tied to the charged conduct.
Why It Matters
This decision clarifies how Montana courts should evaluate attempts to introduce a victim’s sexual history or online activity in non-sex-offense prosecutions — a context where the Rape Shield Statute does not apply by its terms. The Court confirms that Rule 403’s balancing test performs essentially the same gatekeeping function in such cases, and that the relevant inquiry is tightly scoped: only evidence tied to the defendant’s actual knowledge of the victim’s consent to the specific act charged clears the relevance bar.
For practitioners, the case illustrates that defendants cannot bootstrap general evidence of a victim’s sexual interests into a consent or mental-state defense without a concrete link to the conduct at issue. It also signals that equating a felony act of domestic violence with consensual activity will receive no traction as an evidentiary or rhetorical argument before the Montana Supreme Court.
