What happens when a plea affidavit contains ambiguous elements? State v. Lehi Explained

The Utah Court of Appeals in State v. Lehi addressed a critical issue that arises when plea affidavits contain ambiguities about which statutory elements apply to a defendant’s specific case. The decision underscores the importance of strict compliance with Rule 11 requirements, even when defendants may subjectively understand the charges against them.

Background and Facts

Edwin Lehi was charged with DUI with two prior convictions after being observed driving impaired at a convenience store. The investigating officer noted Lehi’s lack of balance, slurred speech, and strong alcohol odor, but Lehi refused breathalyzer testing. Lehi entered a plea agreement to plead guilty to DUI in exchange for dismissal of other charges and a ninety-day jail recommendation. However, his plea affidavit only referenced the blood alcohol concentration prong of the DUI statute, despite his refusal to submit to chemical testing.

Key Legal Issues

The central issue was whether the trial court ensured Lehi understood the nature and elements of the DUI charge under Rule 11(e)(4)(A). The DUI statute contains two alternative prongs: blood alcohol concentration of .08 or greater as shown by chemical testing, or being under the influence to a degree that renders one incapable of safely operating a vehicle. Since Lehi refused testing, he could only be convicted under the second prong.

Court’s Analysis and Holding

The court found that while the plea affidavit was properly incorporated into the record, it contained fatal ambiguities. The affidavit referenced only the blood alcohol concentration elements, which were inapplicable given Lehi’s refusal to submit to testing. Additionally, Lehi’s factual basis statement that he “had been drinking” and was “driving” was insufficient to establish the elements of DUI, as drinking and driving alone does not constitute the offense without proof of impairment or blood alcohol concentration.

Practice Implications

This decision reinforces that trial courts must clarify any ambiguities in plea affidavits during the plea colloquy. Courts cannot assume defendants understand which statutory prong applies to their case, even when dealing with repeat offenders. The ruling emphasizes that strict Rule 11 compliance requires addressing discrepancies between charging documents and plea affidavits to ensure defendants understand the specific elements under which they can be convicted.
