Must Utah courts instruct juries on the State's burden to disprove affirmative defenses? State v. Sellers Explained

In State v. Sellers, the Utah Court of Appeals addressed a critical jury instruction issue that highlights the importance of properly allocating the burden of proof for affirmative defenses. This case serves as an essential reminder for Utah practitioners about the counter-intuitive nature of burden allocation in criminal defense cases.

Background and Facts

Justin Sellers was charged with aggravated sexual abuse of a child after allegedly touching a thirteen-year-old’s genitalia while heavily intoxicated. Sellers had consumed significant amounts of alcohol at a party, passed out multiple times during the evening, and a partially empty pint of vodka was found in the victim’s room. The case involved proving both general intent to touch and specific intent to cause pain or arouse sexual desires under Utah Code Ann. § 76-5-404.1.

Key Legal Issues

The central issue was whether the trial court’s voluntary intoxication instruction properly informed the jury about the burden of proof. While the instruction explained that voluntary intoxication could negate the specific intent element, it failed to specify that the State bore the burden of disproving this affirmative defense beyond a reasonable doubt. Sellers also raised claims regarding evidentiary issues and ineffective assistance of counsel.

Court’s Analysis and Holding

The court found that while Sellers had invited the instructional error by proposing a similarly defective instruction, this did not preclude review for ineffective assistance of counsel. The court emphasized that Utah’s long-standing law requires the State to disprove affirmative defenses beyond a reasonable doubt, and this “counter-intuitive” burden allocation must be made plain to juries. Defense counsel’s failure to object to the incomplete instruction constituted deficient performance with no legitimate tactical explanation. The error created a reasonable probability of a different outcome, satisfying the prejudice prong under Strickland.

Practice Implications

This decision reinforces that Utah practitioners must be vigilant about burden of proof instructions for affirmative defenses. The court noted that juries naturally assume defendants bear the burden of proving their own defenses, making explicit instruction essential. The opinion also provides guidance on evidentiary issues likely to recur at retrial, including limitations on lay opinion testimony about intoxication and the admissibility of interrogation statements about witness credibility. Practitioners should ensure that proposed jury instructions clearly allocate the burden to the State for disproving affirmative defenses.
