Yes, this season appears to be the one to address a number of lingering or ambiguous (or not so ambiguous) issues about Mil. R. Evid. 412. So, it seems apt that the last opinion for this season is out: United States v. Ellenbrock.
We granted review to determine whether the military judge erred in applying Military Rule of Evidence (M.R.E.) 412 to prevent Appellant from introducing evidence of the alleged victim’s first marital affair to show a motive to fabricate the accusation against Appellant. We hold that the evidence was constitutionally required, that the military judge abused her discretion by refusing to admit the evidence, and that it was not harmless beyond a reasonable doubt.
Appellant moved under M.R.E. 412 to introduce testimony that CL had engaged in a prior extramarital affair to support his theory that CL had a motive to lie about the consensual nature of the sex with him, which was to protect her marriage.
