When does introducing a client's prior conviction constitute ineffective assistance of counsel? State v. Fowers Explained

In State v. Fowers, the Utah Court of Appeals addressed a critical question about ineffective assistance of counsel: when does a defense attorney’s decision to introduce evidence of a client’s prior conviction cross the line from strategy into deficient performance?

Background and facts

William Fowers was charged with two counts of criminal solicitation involving fifteen-year-old boys. The prosecution alleged that Fowers approached the boys near their alternative high school and solicited oral sex. Before trial, the State sought to introduce evidence of Fowers’s twenty-five-year-old conviction for sodomy on a child. The trial court excluded this evidence under Rule 403, finding it would be substantially more prejudicial than probative.

Despite this ruling, defense counsel later introduced the prior conviction during direct examination, stating: “Just because I know the State probably is going to bring it up, you’ve been to prison before?” This led to testimony about the sodomy conviction and Fowers’s bisexuality, which the prosecutor later used in closing arguments to suggest a connection between sexual orientation and criminal behavior.

Key legal issues

The central issue was whether defense counsel’s introduction of the excluded prior conviction evidence constituted ineffective assistance of counsel under the Strickland standard, requiring proof of both deficient performance and prejudice.

Court’s analysis and holding

The Court of Appeals found defense counsel’s performance deficient for two reasons. First, the defense had already obtained a favorable ruling excluding the evidence. Second, the court could “conceive of no sound tactical reason” for introducing evidence that a defendant charged with soliciting oral sex from boys had previously been convicted of a sex act with a minor. The court rejected the State’s argument that counsel had a strategic purpose, noting the transcript showed counsel’s misunderstanding about the court’s ruling rather than tactical advantage.

Regarding prejudice, the court emphasized this was a credibility contest with no corroborating physical evidence. The prior conviction evidence was particularly prejudicial because it suggested “a verdict on an improper, emotional basis.” The court concluded there was a reasonable probability of a more favorable outcome without this evidence.

Practice implications

This case demonstrates the critical importance of understanding evidentiary rulings before introducing potentially damaging evidence. Defense attorneys must carefully confirm whether prior convictions remain excluded when defendants testify, rather than operating on assumptions. The decision also highlights how the introduction of highly prejudicial evidence in credibility-based cases can constitute reversible error, particularly in sex offense prosecutions where such evidence carries exceptional prejudicial weight.
