U.S. v. Byrd, 60 M.J. 4

Core Criminal Law Subjects: Evidence: Opinion Testimony

1. this case concerns whether MRE 701 allows a lay witness to interpret what appellant meant when he wrote certain passages in letters to the witness; we agree with the well-established federal civilian rule that this kind of lay opinion testimony is, with certain limited exceptions, impermissible
2. MRE 701 establishes a two-part test for admissibility of lay opinion: (1) the opinion must be rationally based on the witness’s perception; and (2) the opinion must be helpful to the determination of a fact in issue
3. the general rule in federal civilian courts is that lay witnesses are normally not permitted to testify about their subjective interpretations or conclusions as to what has been said; such lay interpretations are admissible only if rationally based on perception of a witness and helpful either to an understanding of the testimony of the witness on the stand or to the determination of a fact in issue; for example, a lay witness may be permitted to interpret coded or code-like conversations; in order to allow lay opinion testimony interpreting a facially coherent conversation, the government would have to establish a foundation that called into question the apparent coherence of the conversation so that it no longer seemed clear, coherent, or legitimate
4. this Court agrees with the general prohibition of lay opinion testimony interpreting facially coherent communications; where terms are capable of being understood by the layman, and where the jury is capable of interpreting the language or slang involved, lay witness opinion testimony is improper, as is the lay witness’s conclusion or interpretation of the conversation
5. for a lay opinion interpreting another person’s meaning to be admissible, the proponent must establish that the witness has some special basis for determining the speaker’s true meaning; once that foundation is laid, the witness may clarify conversations that are abbreviated, composed of unfinished sentences and punctuated with ambiguous references to events that were clear only to the conversation participants, or which include code or code-like language; when such permissible testimony is presented, the accuracy of those perceptions is a question for the members
6. a witness’s opinions concerning appellant’s meaning in passages in his letters that were facially coherent were inadmissible; a witness’s opinions concerning appellant’s meaning when he wrote certain ambiguous statements were also inadmissible because they were unaccompanied by any particularized demonstration that the witness had a basis for determining appellant’s true meaning; it was not enough to show that the witness was familiar with appellant’s handwriting and had corresponded with him in the past; as the proponent of this testimony, the Government was required to demonstrate that the witness had some basis for knowing appellant’s intended meaning for the particular phrases that the witness purported to interpret; a witness’s testimony providing background information concerning references in the letters to other events was admissible; and a witness’s testimony concerning appellant’s remarks in earlier conversations was admissible as an account of admissions by a party opponent under MRE 801(d)(2)

Trial Stages: Appeals: Harmless / Prejudicial Error

1. we evaluate prejudice from an erroneous evidentiary ruling by weighing (1) the strength of the Government’s case, (2) the strength of the defense case, (3) the materiality of the evidence in question, and (4) the quality of the evidence in question; the burden of demonstrating harmlessness rests with the Government
2. although the military judge improperly allowed a lay witness to offer her opinion about appellant’s meaning in various passages of letters he wrote to her, this Court finds the error to be harmless where the inadmissible testimony was of limited materiality and insignificant

Trial Stages: Appeals: Standards of Review, Burdens, etc.

1. like other evidentiary rulings, a military judge’s application of MRE 701 is reviewed for an abuse of discretion; a trial judge’s ruling is entitled to due deference; this Court will reverse for an abuse of discretion only if the military judge’s findings of fact are clearly erroneous or if his decision is influenced by an erroneous view of the law
