Summary

Dustin Bird was charged with failure to respond to an officer’s signal to stop after he continued driving briefly after police activated their lights. The trial court denied defense counsel’s request for a jury instruction defining the mental state required for conviction. The Utah Court of Appeals reversed, finding the trial court should have instructed the jury on the mens rea elements.

Analysis

The Utah Supreme Court’s decision in State v. Bird provides important guidance for criminal practitioners regarding when trial courts must instruct juries on mens rea requirements, even for traffic offenses that use common terminology.

Background and Facts

Dustin Bird was charged with failure to respond to an officer’s signal to stop under Utah Code section 41-6a-210 after he continued driving briefly when police activated their emergency lights. Defense counsel requested a jury instruction defining the mental state required for conviction, but the trial court denied the request. The court gave only an elements instruction that tracked the statutory language requiring that the defendant “received a visible or audible signal from a peace officer” and “did attempt to flee or elude a peace officer.” The prosecution argued the jury did not need to “look into the defendant’s mind” to determine culpability.

Key Legal Issues

The central issue was whether the trial court erred by refusing to instruct the jury on the mental state requirements for the failure to respond charge. The Court also addressed whether the Utah Court of Appeals erred by not providing guidance on remand regarding the proper jury instruction.

Court’s Analysis and Holding

The Utah Supreme Court affirmed the Court of Appeals’ reversal, holding that the trial court erred by not providing a mens rea instruction. The Court explained that the statutory terms “receive” and “attempt” incorporate mental state requirements that are not automatically obvious to lay jurors. While “receive” implies knowledge of the officer’s signal, and “attempt to flee or elude” requires intentional conduct, juries need explicit instruction on these mens rea implications. The Court distinguished between common dictionary definitions and legal meanings, noting that “attempt” in criminal law requires more than mere effort—it requires a conscious decision with specific purposeful action.

Practice Implications

Defense attorneys should always request specific mens rea jury instructions for criminal charges, particularly when statutes use terms like “receive,” “attempt,” “intend,” or other words that imply mental states. Even if such terms have common meanings, their legal significance as essential elements must be explained to juries. The decision reinforces that failing to instruct on required mental states constitutes reversible error when mens rea is an element of the offense.
