Utah Supreme Court
Can Utah classify measurable substance offenses as more serious than DUI offenses? State v. Ainsworth Explained
Summary
Thomas Ainsworth was convicted of three second degree felonies for causing death and injury while driving with methamphetamine in his system. The court of appeals vacated his convictions, finding the measurable substance statute unconstitutional under the Uniform Operation of Laws Clause because it punished less culpable conduct more harshly than DUI offenses. The Utah Supreme Court reversed, holding the statutes are constitutional because they require different elements of proof.

Analysis
In State v. Ainsworth, the Utah Supreme Court addressed a significant constitutional challenge to Utah’s drunk driving statutes, ultimately upholding the legislature’s authority to classify certain drug-related driving offenses more severely than traditional DUI charges.
Background and Facts
On Christmas Eve 2011, Thomas Ainsworth drove his vehicle over a median and crashed head-on into another car while methamphetamine was in his system. The collision killed an 18-month-old child and seriously injured both parents. Ainsworth was charged with three second degree felonies under Utah’s measurable substance provisions, which criminalize causing death or injury while driving with any measurable amount of a Schedule I or II controlled substance in one’s body. Ainsworth challenged these charges, arguing he should have been charged under the less severe DUI provisions as third degree felonies.
Key Legal Issues
The central issue was whether Utah’s Uniform Operation of Laws Clause was violated by classifying measurable substance offenses as second degree felonies while DUI offenses requiring proof of actual impairment are classified as third degree felonies. Ainsworth argued it was irrational to punish someone with “any measurable amount” of a controlled substance more harshly than someone proven to be actually impaired.
Court’s Analysis and Holding
The Utah Supreme Court rejected this constitutional challenge, clarifying that the Shondel doctrine does not apply because the two statutory schemes are not wholly duplicative. While DUI provisions require proof of impairment “to a degree that renders the person incapable of safely operating a vehicle,” the measurable substance provisions require proof that the substance is specifically a Schedule I or II controlled substance. The court found this distinction provided a rational basis for the different penalty classifications, noting that Schedule I and II drugs have greater potential for abuse and dependence.
Practice Implications
This decision significantly impacts criminal defense practice in Utah. Practitioners must understand that prosecutors retain discretion in choosing between DUI and measurable substance charges when both may apply. The ruling also reinforces that constitutional challenges to penalty classifications require showing that statutes are truly duplicative in their elements, not merely similar in their underlying conduct. Finally, the court’s affirmance of consecutive sentencing demonstrates the broad discretion trial courts maintain in sentencing decisions.

Case Number
No. 20160173
Date Decided

Outcome
Affirmed in part and Reversed in part
Holding
The classification of measurable substance offenses as second degree felonies does not violate the Uniform Operation of Laws Clause because these offenses require proof that the controlled substance is a Schedule I or II drug, making them distinct from DUI offenses.
Standard of Review
Correctness for the constitutional challenge under the Uniform Operation of Laws Clause; abuse of discretion for consecutive sentencing decisions
Practice Tip
When challenging prosecutorial charging decisions between similar offenses, ensure the statutes are wholly duplicative in their elements, as the Shondel doctrine only applies when two statutes require proof of identical elements.
