350 P.3d 344
Idaho Ct. App.2015Background
- Leroy S. Wilske was arrested after officers found him in a running vehicle with signs of impairment; breath test at the jail showed BAC well over the legal limit.
- During a post-arrest search, officers found marijuana and drug paraphernalia in the vehicle; Wilske admitted recent marijuana use but said the items belonged to a friend.
- Wilske was charged with felony DUI and two misdemeanors (possession of a controlled substance and possession of drug paraphernalia); the magistrate consolidated the separate filings and the State filed a single information alleging all three counts.
- Wilske moved to sever the misdemeanor possession counts from the DUI charge, arguing joinder would unfairly prejudice the jury (they might infer criminal disposition from the drug evidence).
- The district court denied severance, finding the offenses and proofs were separate and distinct and that a jury instruction to consider each count independently would mitigate prejudice.
- The jury convicted on all counts; on appeal the Court of Appeals affirmed, concluding the district court did not abuse its discretion in denying severance.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether joinder of DUI and misdemeanor possession charges was unfairly prejudicial under I.C.R. 14 | State: joinder proper; possession counts not so serious or inflammatory to cause prejudice and issues were narrow | Wilske: joinder would cause jurors to infer criminal propensity from marijuana possession and convict on DUI for that reason | Denied severance; no abuse of discretion—the offenses were separate/distinct and jury instruction mitigated prejudice |
