Colo.2021Background
- In Feb. 2015 Clarence Mosely was ejected from a strip club after a confrontation; later, a fight in the parking lot culminated in Mosely stabbing T.K.
- Mosely was charged with first-degree assault, felony menacing, and crime-of-violence enhancers; he asserted self-defense at trial.
- Jury was instructed that self-defense consists of four components (two substantive conditions and two exceptions) and that the People must disprove at least one component beyond a reasonable doubt for the defense to fail.
- During deliberations jurors asked whether they had to unanimously agree on which component was disproved; the trial court said they must unanimously find self-defense disproven but need not agree on the specific component.
- Jury convicted Mosely (lesser included second-degree assault and felony menacing); the court of appeals reversed the felony menacing conviction for lack of unanimity on the specific self‑defense component.
- The Colorado Supreme Court granted certiorari and reversed the court of appeals, holding unanimity on the specific reason self‑defense was disproven is not required so long as the jury unanimously agrees the defense was disproven beyond a reasonable doubt.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether due process requires jurors to unanimously agree on which specific component/exception of self‑defense the prosecution disproved beyond a reasonable doubt | People: unanimity as to verdict suffices; no separate unanimity requirement for which component was disproved | Mosely: jurors must unanimously identify which component/exception was disproven because components are factual elements | Court: No. Jury need only unanimously agree self‑defense was disproven; unanimity as to the specific means is not required |
| Whether the trial court’s supplemental clarification (that jurors need not agree on which condition was disproven) conflicted with general unanimity instruction | People: clarification was consistent and necessary to resolve juror confusion | Mosely: supplemental instruction contradicted "all parts" unanimity instruction | Court: Supplemental instruction properly clarified jury obligation and did not violate due process |
| Whether mutually exclusive exceptions (provocation vs initial aggressor) require unanimous finding on which exception applies | People: even if mutually exclusive, jurors can reasonably disagree on alternative means; only unanimous overall finding that self‑defense failed is required | Mosely: mutually exclusive exceptions mean jurors must agree which exception applies | Court: Not necessary to decide exclusivity; regardless, disagreement on alternative theories does not defeat a unanimous guilty verdict so long as all jurors agree the defense failed |
