Digested under 12 topics

Military Justice Personnel: Military Judge: Discretion

  1. a military judge is given broad discretion to impose reasonable limitations on cross-examination
  2. MRE 611(b) authorizes cross-examination into matters affecting the credibility of the witness; when appellant elected to testify, he placed his credibility at issue and the government’s cross-examination as to the statements he had made to a sexual assault nurse examiner was designed to explore that credibility; as such, the government could properly test appellant’s credibility on cross-examination; when appellant then testified on cross-examination as to what he had told the nurse during the sexual assault examination, his credibility remained at issue, and his testimony was opened to impeachment by contradiction by having the nurse testify to the contrary; although appellant’s statements were unwarned, MRE 304(b)(1) [now MRE 304(e)(1)] specifically provides for the use of unwarned statements for purposes of impeachment by contradiction; therefore, the military judge did not abuse her discretion in overruling the defense objection that the government’s cross-examination exceeded the scope of direct examination and by subsequently allowing impeachment by contradiction
  3. in this case, reviewing the evidence in the light most favorable to the government, the military judge did not abuse her discretion in finding that appellant’s consent to a sexual assault evaluation was voluntary; while appellant may have believed that his liberty was restricted to some degree and while he did ask whether he should get an attorney, those factors are not sufficient to invalidate his consent; once appellant arrived at the clinic, he was told several times that his decision to consent to the exam was voluntary and that he could refuse; and the consent form that he reviewed and signed clearly reiterated those rights

  2. when an accused takes the stand, the privilege against self-incrimination is waived; an accused is not required to testify in his defense and his failure to do so may not be the basis for any inference against him; but where he does elect to testify, his credibility may be impeached like that of other witnesses; hence, though he may not be cross-examined as to his general character, he may be so examined as to his credibility
  3. MRE 611(b) authorizes cross-examination into matters affecting the credibility of the witness; when appellant elected to testify, he placed his credibility at issue and the government’s cross-examination as to the statements he had made to a sexual assault nurse examiner was designed to explore that credibility; as such, the government could properly test appellant’s credibility on cross-examination; when appellant then testified on cross-examination as to what he had told the nurse during the sexual assault examination, his credibility remained at issue, and his testimony was opened to impeachment by contradiction by having the nurse testify to the contrary; although appellant’s statements were unwarned, MRE 304(b)(1) [now MRE 304(e)(1)] specifically provides for the use of unwarned statements for purposes of impeachment by contradiction; therefore, the military judge did not abuse her discretion in overruling the defense objection that the government’s cross-examination exceeded the scope of direct examination and by subsequently allowing impeachment by contradiction

  2. to determine whether a consent was voluntary, the following six nonexclusive factors set forth in US v. Wallace, 66 MJ 5 (CAAF 2008) may be examined: the degree to which liberty was restricted, the presence of coercion, a suspect’s awareness of the right to refuse based on inferences of the suspect’s age, intelligence, and other factors, the suspect’s mental state at the time, consultation, or lack thereof, with counsel, and the coercive effects of any prior violations of the suspect’s rights
  3. although access to counsel is relevant to the analysis of whether a consent to a search is voluntary, there is no right to have an attorney before consent is granted
  4. in this case, reviewing the evidence in the light most favorable to the government, the military judge did not abuse her discretion in finding that appellant’s consent to a sexual assault evaluation was voluntary; while appellant may have believed that his liberty was restricted to some degree and while he did ask whether he should get an attorney, those factors are not sufficient to invalidate his consent; once appellant arrived at the clinic, he was told several times that his decision to consent to the exam was voluntary and that he could refuse; and the consent form that he reviewed and signed clearly reiterated those rights
