Defendant appeals a judgment of conviction for sexual abuse in the first degree, ORS 163.427, and sodomy in the first degree, ORS 163.405, relating to his four-year-old stepdaughter. On appeal, defendant contends that the trial court plainly erred by failing to sua sponte strike two pieces of testimony as impermissible vouching. He further contends that the trial court plainly erred in failing to recuse itself for bias. We affirm.
Defendant acknowledges that he did not preserve any of his claims of error. We may review an unpreserved claim of error if it is “plain,” that is, if the error is (1) “one of law”; (2) “obvious, not reasonably in dispute”; and (3) “appears on the face of the record, so that we need not go outside the record to identify the error or choose between competing inferences, and the facts constituting the error are irrefutable.” State v. Corkill, 262 Or. App. 543, 551, 325 P.3d 796, rev. den., 355 Or. 751, 331 P.3d 1010 (2014) (internal quotation marks omitted).
Defendant first assigns error to the trial courts failure to sua sponte strike testimony from a Department of Human Services (DHS) child protective services worker who testified about her interview with defendants stepdaughter. The DHS worker described the “protocol” that DHS uses when interviewing a child to “gauge whether or not they have an understanding of * * * the difference between a truth and a lie.” After the DHS worker provided an example of that “protocol” involving the child witness truthfully identifying the color of a pen, the following exchange occurred:
“[Prosecutor]: Okay. And did she say she would only talk about true things with you in that interview?
“[Witness]: Yes, she did.
“[Prosecutor]: Okay. And what did [she] tell you when you spoke with her?”
The DHS worker next testified that the child disclosed sexual abuse.
Defendant contends that the DHS workers testimony constituted impermissible vouching because it was “tantamount” to a comment on the child witnesss credibility. See, e.g., State v. Beauvais, 357 Or. 524, 543, 354 P.3d 680 (2015) (“A direct comment on the credibility of a witness or a statement that is ‘tantamount’ to stating that another witness is truthful is not admissible[.]”). However, commenting on the competency—as opposed to the credibility—of a child witness is not impermissible vouching. See id. at 545, 354 P.3d 680 (“Expert testimony that provides jurors with useful information in making their own credibility assessment ordinarily is admissible[.]”).
In Smith v. Franke, we evaluated a police officers testimony about the “protocol” involved when interviewing a child, including the practice of asking the child to truthfully describe the color of an object to “demonstrate[ ] to [the officers] satisfaction that she knew what it was to tell the truth and what it was to tell a lie.” 266 Or. App. 473, 476, 337 P.3d 986 (2014), rev. den., 356 Or. 689, 344 P.3d 1111 (2015). We concluded that the testimony did not amount to impermissible vouching because the officer did not comment on whether she believed that the child was telling the truth, but rather spoke only to the competency of the child to differentiate a true statement from a lie. Specifically, “[t]estimony that a child demonstrated knowledge of the difference between the truth and a lie does not amount to testimony that the child did not lie, nor does it otherwise pass on the credibility of that child either directly or indirectly.” Id. at 479-80, 337 P.3d 986.
In light of the similarities between the DHS workers testimony in this case and that of the officer in Smith, it is far from “obvious” that the testimony constituted a direct statement on the stepdaughters credibility such that the trial court should have struck it sua sponte. See Corkill, 262 Or. App. at 552, 325 P.3d 796 (recognizing that cases where a trial court should have sua sponte excluded testimony as impermissible vouching typically involve “true ‘vouching’ ” evidence, that is, a “witnesss testimony that he or she believes that another witness is or is not credible, which a party offers to bolster or undermine the veracity of that other witness”).
Defendant next assigns error to the trial courts failure to strike testimony from a child counselor who testified that the childs statements were internally consistent and that the counselor had advised the child to tell the truth in court. As with the DHS workers testimony, however, the counselors testimony did not involve true vouching—that is, a witness commenting on the credibility of other witnesses. It is not “obvious” that a witnesss observation as to the consistency of the content of the childs statements is a comment on the childs credibility. As far as advising the child to tell the truth, the counselor again did not assert that she believed that the child was truthful, rather that, much like any witness in a courtroom who takes an oath, the child was advised to tell the truth. Nothing about the counselors testimony was true vouching such that the trial court was required to strike it sua sponte.
Defendants final assignment of error challenges the trial courts failure to sua sponte recuse itself based on its personal knowledge of defendant. However, defendant does not identify any personal knowledge beyond knowledge gained through presiding over other court matters involving defendant, nor does defendant cite any cases in which a trial court was required to sua sponte recuse itself based on similar circumstances. The trial court did not plainly err in declining to recuse itself.
Affirmed.
