A 10-year analysis of how outcomes from Utah House Bill 348 evolved in practice, highlighting what changed, what persisted, and what shaped long-term results.

What happened after Utah’s 2015 justice system law was enacted? This report, developed with generous support from Arnold Ventures, examines how outcomes from Utah House Bill 348 changed over the following decade, drawing from ten years of data on incarceration, supervision, treatment access, and system capacity. The analysis finds that some impacts—such as sustained reductions in incarceration for drug possession and recent declines in probation and parole revocations—persisted over time, while others diminished as population growth, behavioral health needs, and later policy and practice changes reshaped the system. Overall, the findings show that long-term results depended less on the law itself and more on how policies were implemented, resourced, and adapted within an evolving justice system.
