Background
Dylan River Lossing drove while intoxicated, crashed, and killed another driver. He pleaded no contest to gross vehicular manslaughter while intoxicated and two injury-DUI counts, with great-bodily-injury enhancements. The trial court imposed four years for manslaughter, stayed punishment on the DUI counts, and imposed enhancement terms.
The DUI convictions’ classification as violent felonies limited Lossing’s ability to earn custody credits. He argued that injury DUI under Vehicle Code section 23153 was a lesser included offense of gross vehicular manslaughter under Penal Code section 191.5 and therefore had to be dismissed. Division Six had previously accepted that position when the offenses involved the same victim, but other courts disagreed.
The Court’s Holding
The Second District affirmed and overruled its earlier approach. Under California’s statutory-elements test, one crime is necessarily included in another only when the greater offense cannot be committed without committing the lesser. Gross vehicular manslaughter while intoxicated can rest on predicate intoxication offenses other than injury DUI, so section 23153 is not necessarily included.
The court rejected a case-specific focus on the charged predicate or shared victim because that resembles the accusatory-pleading test, which California does not use to determine whether multiple convictions are permitted. Concerns about harsher collateral consequences or the absence of another lesser offense cannot change the elements analysis. Multiple convictions may stand, although Penal Code section 654 can still prohibit multiple punishment for the same act.
Key Takeaways
- Injury DUI is not a lesser included offense of gross vehicular manslaughter while intoxicated.
- Courts compare statutory elements in the abstract, not the particular charging theory or facts.
- A disjunctive statute with alternative predicate offenses defeats necessary inclusion when some alternatives omit elements of the claimed lesser offense.
- Multiple convictions and multiple punishments are separate questions; section 654 may stay punishment without requiring dismissal.
- Collateral effects such as custody-credit limits do not alter the lesser-included-offense test.
Why It Matters
The decision resolves an intra-state split and permits prosecutors to retain injury-DUI convictions alongside vehicular-manslaughter convictions arising from the same fatal crash. Those additional convictions can carry consequences even when their sentences are stayed, including violent-felony classifications and reduced worktime credits.
Defense counsel should distinguish challenges to conviction from challenges to punishment and advise clients about collateral effects before a plea. Prosecutors and trial courts should identify the precise statutory predicates and ensure section 654 stays are correctly imposed. The court’s strict elements-based methodology may also affect lesser-included arguments involving other crimes written with alternative predicate acts.
