State v. Delaney, 522 P.3d 855

Background

Defendant Anthony Delaney was charged in one indictment with six sex offenses arising from two separate incidents and victims (M: 2014; L: 2016).
Delaney moved to sever counts by victim under ORS 132.560(3), arguing joinder would cause substantial prejudice because the prosecutor warned M would testify she came forward after having “heard” Delaney harmed other women.
At the severance hearing the prosecutor “clarified” the victims’ motivations as generalized concern Delaney might harm others (including concern for a friend) rather than explicit testimony that M had heard he harmed other women; Delaney did not offer an alternative prejudice theory.
The trial court denied severance; at trial neither victim testified that she had heard Delaney harmed other women, and the jury convicted on all counts.
The Court of Appeals affirmed; the Oregon Supreme Court granted review to clarify the meaning and review standard for “substantial prejudice” under ORS 132.560(3).
The Supreme Court held that a movant must identify a case-specific theory of substantial prejudice (beyond the inherent risk from joinder), that whether prejudice exists is a legal question reviewed de novo, and that here the trial court did not err because the record permitted the court to infer the state would not offer the prejudicial testimony.

Issues

Issue	State's Argument	Delaney's Argument	Held
Review standard for whether joinder causes "substantial prejudice"	Miller and other precedent should not be overruled; the trial court’s decision is legal and reviewable for errors of law	Deference should apply (aligning with federal abuse-of-discretion approach)	Whether prejudice exists is a question of law reviewed de novo; relief choice remains discretionary to trial court.
What showing is required to win severance under ORS 132.560(3)	Movant must show case-specific substantial prejudice—aligning with federal principles—beyond the inherent risk of joinder	Any substantial detriment to defense from evidence of other acts (e.g., testimony that a victim came forward after hearing about other victims) suffices	Movant must articulate a case-specific theory of prejudice that goes beyond ordinary joinder risks.
Role of “simple and distinct” evidence	Simple and distinct evidence often mitigates prejudice and supports denying severance	Simple/distinct test cannot defeat severance where propensity-type evidence will unduly influence the jury	“Simple and distinct” is probative but not dispositive; some theories (e.g., jury treating one conviction as proof of others or admitting propensity evidence) can require severance even if evidence is simple and distinct.
Application to this record (prosecutor’s statements about M’s motivation)	The prosecutor’s clarification permitted the court to infer the state would not offer the specifically prejudicial testimony	The initial statement that M came forward because she’d "heard" Delaney harmed other women proved case-specific, substantial prejudice requiring severance	Trial court did not err: the record allowed the court to infer the State would not elicit the prejudicial testimony, and neither victim ultimately testified to having heard about other victims.
