Judge HARDY delivered the opinion of the Court. The Government charged Appellant with two specifica- tions of sexual assault under Article 120, Uniform Code of Military Justice (UCMJ), 10 U.S.C. § 920. A general court- martial consisting of an eight-member panel with enlisted representation acquitted Appellant of the first specification but found Appellant guilty of the second specification. Based on information learned during a “hot wash” session1 with the senior panel member, Captain (Capt) Sierra, Ap- pellant’s military trial defense counsel came to believe that Appellant’s panel misunderstood how nonunanimous ver- dicts and hung juries work in the military justice system and erroneously thought that a minimum of six votes were required to convict or to acquit Appellant on each charge. Appellant’s defense counsel obtained an affidavit from Capt Sierra affirming this misunderstanding and further stating that the panel initially conducted several rounds of voting where three or more members voted to find Appel- lant not guilty of the second specification. The affidavit went on to state that if the members had properly under- stood the voting rules, Capt Sierra would have filled out the findings worksheet to reflect findings of not guilty for both specifications. After obtaining Capt Sierra’s affidavit, Appellant’s de- fense counsel filed a post-trial motion asking the military judge to correct the verdict pursuant to Rules for Court- Martial (R.C.M.) 922 and 1104. After receiving briefs from both parties and conducting a post-trial Article 39(a) hear- ing, 2 the military judge issued a written ruling declining to consider Capt Sierra’s affidavit and denying Appellant’s motion. The United States Navy-Marine Corps Court of

outside the presence of the members for specific purposes).

2 United States v. RosarioMartinez, No. 25-0102/MC Opinion of the Court

Criminal Appeals (NMCCA) affirmed. RosarioMartinez, 85 M.J. at 545. On appeal to this Court, we specified the following issue: Did the military judge err in finding the affidavit of the senior member to be incompetent evidence under MRE 606(b)(2)(C) and in denying Appel- lant’s motion for appropriate relief to correct an error in the findings worksheet? United States v. RosarioMartinez, 85 M.J. 463 (C.A.A.F. 2025) (order granting review). For the reasons set forth below, we hold that the mili- tary judge did not abuse his discretion when he declined to consider Capt Sierra’s affidavit after finding that it was not competent evidence. We therefore affirm the findings and sentence as affirmed by the NMCCA. I. Background The Government charged Appellant with two specifica- tions of sexual assault under Article 120, UCMJ, following the victim’s report that Appellant had assaulted her in her barracks room after the two had gone out drinking to- gether. The two specifications were pleaded in the alterna- tive based on contingencies of proof. The first specification was charged under the theory that Appellant performed a sexual act upon the victim when he knew or reasonably should have known that she was asleep. The second speci- fication was charged under the theory that Appellant per- formed a sexual act upon the victim without her consent. A. Appellant’s Court-Martial Appellant’s general court-martial consisted of eight members with enlisted representation. Following the presentation of evidence, the military judge instructed the members on voting, including the following: The concurrence of at least three-fourths of the members present when the vote is taken is re- quired for any finding of guilty. Since we have

eight members, that means six members must concur in any finding of guilty. If you have at least six votes of guilty of any offense, then that will result in a finding of guilty for that offense. If fewer than six members vote for a finding of guilty, then your ballot resulted in a finding of not guilty. You may reconsider any find- ing prior to its being announced in open court. However, after you vote, if any member expresses a desire to reconsider any finding, open the court and the president should announce only that a consideration of a finding has been proposed. (Emphasis added.) Neither party objected to the instruc- tions or requested any additional instructions. The military judge did not provide a written copy of the voting instruc- tions to the panel. The panel deliberated for two days. On two separate oc- casions, the members requested to reopen the court-mar- tial, but neither of these occasions concerned questions about the findings worksheet or the panel instruction on voting. After the panel reached a verdict, the military judge reviewed the findings worksheet and asked Capt Sierra to announce the panel’s findings. Capt Sierra stated that the court-martial found Appellant not guilty of the first speci- fication, but guilty of the second specification—sexual as- sault without consent—under Article 120, UCMJ. After Appellant elected to be sentenced by the military judge, the military judge excused the panel and instructed the mem- bers not to discuss their deliberations with anyone unless ordered to do so by a court. That same day, the military judge sentenced Appellant to a dishonorable discharge and eighteen months of confinement. B. Capt Sierra’s Affidavit In the days following trial, Appellant’s two defense counsel conducted a hot wash with Capt Sierra, the senior panel member, to receive feedback on their advocacy. Dur- ing the conversation, Capt Sierra asked how the military justice system handles hung juries. Appellant’s counsel ex- plained to Capt Sierra that hung juries do not exist in the

military, and that when fewer than three-quarters of the panel vote to convict, the result is an acquittal. Upon hear- ing this, Capt Sierra said “ ‘[w]ell, then we acquitted your client’ ” or words to that effect. Capt Sierra further told Ap- pellant’s counsel that the panel had conducted multiple votes in the absence of any vote to reconsider—several of which rendered fewer than six votes for guilty—before the panel finally reached six votes in favor of finding Appellant guilty of the second specification.
