Can defendants challenge evidence they introduced during cross-examination? State v. Harper Explained

In State v. Harper, the Utah Court of Appeals addressed several appellate issues arising from a conviction for aggravated sexual abuse of a child, including whether defendants can challenge evidence they themselves elicited during cross-examination.

Background and Facts

Harper was convicted of two counts of aggravated sexual abuse based on allegations that he digitally penetrated an eleven-year-old victim during an overnight stay at her home. During cross-examination of a witness, defense counsel asked questions about Harper’s character for honesty, which elicited unexpected and prejudicial testimony about prior allegations against Harper. The State then used redirect examination to rehabilitate the witness’s credibility regarding the victim’s truthfulness.

Key Legal Issues

The court addressed multiple issues: whether jury instructions misstated the law, whether the State improperly introduced character evidence on redirect examination, whether the trial court erred in denying a tender years instruction, and whether defense counsel provided ineffective assistance by failing to seek curative measures after eliciting harmful testimony.

Court’s Analysis and Holding

The court applied the invited error doctrine to preclude review of jury instruction challenges where defense counsel affirmatively stated no objections. Regarding the character evidence, the court held that Harper “opened the door” to the State’s redirect examination by first questioning the witness’s belief in the victim’s credibility. The court explained that parties cannot challenge evidence they themselves introduce, and the State was entitled to minimize the effect of evidence Harper had elicited.

On the ineffective assistance claim, the court found that counsel’s decision not to seek curative measures after eliciting harmful testimony could constitute sound trial strategy, as drawing additional attention to prejudicial evidence might worsen the situation.

Practice Implications

This decision reinforces the “opened door” doctrine and demonstrates the risks of cross-examination without careful preparation. Practitioners must anticipate potential responses and consider whether questions might invite harmful redirect examination. The ruling also shows how strategic decisions by counsel receive deference under Strickland analysis, even when the results are unfavorable.
