481 P.3d 759
Idaho Ct. App.2020Background
- Idaho State Police trooper received two citizen reports of an intoxicated driver and located a matching vehicle, followed it ~1 mile observing swerving, crossing center/fog lines, and wide speed variation; trooper stopped the vehicle.
- On contact, driver Thla Hum Lian had glassy red eyes, denied drinking, and a passenger-side bag contained four unopened boxes of wine.
- Trooper heard a plastic bottle tip over, ordered occupants out, searched for open containers, found two half-full soda bottles, opened them, and detected alcohol.
- Trooper administered field sobriety tests, arrested Lian, and obtained two breath tests (.138 and .137); State charged Lian with felony DUI.
- District court treated the search as a Terry-stop incident search, suppressed evidence from the opened bottles (plain view inapplicable) and suppressed the field sobriety and BAC results as fruits of the poisonous tree, and dismissed the case.
- Court of Appeals reversed: it held the district court erred by failing to apply the automobile exception under a totality-of-the-circumstances probable-cause analysis and erred in suppressing the sobriety/BAC results.
Issues
| Issue | Plaintiff's Argument (State) | Defendant's Argument (Lian) | Held |
|---|---|---|---|
| Whether the automobile exception should have been applied to justify the vehicle search | District court should have analyzed automobile exception; warrantless search permissible if probable cause to search for open containers | Even under automobile exception, trooper lacked probable cause to search (no smell or visible open container) | Court: district court erred by declining automobile-exception analysis and must apply totality-of-the-circumstances test |
| Whether probable cause existed to search for an open container | Totality (citizen tips, matching vehicle, observed erratic driving, glassy eyes, false statement, unopened alcohol on scene, bottle tipping) gave fair probability of open container | No probable cause because officer neither smelled alcohol nor saw an open container before searching | Court: probable cause existed under the totality of circumstances; automobile exception justified the search |
| Whether field sobriety and BAC results were fruits of an unlawful search and properly suppressed | Even if search were unlawful, defendant must show "but-for" causal nexus; trooper had reasonable suspicion and would have conducted tests regardless | Discovery of open containers prompted and tainted the decision to administer tests, so results must be suppressed | Court: district court misallocated burdens and erred—Lian failed to show causal nexus; tests admissible |
