323 P.3d 306
Or. Ct. App.2014Background
- At 2:23 p.m., deputy observed defendant apparently intoxicated at a campground; defendant gave varying accounts of how long he’d been there and how much he drank.
- Deputy arrested defendant and a breath test at 4:03 p.m. showed a .17% BAC.
- At trial defendant testified he drank "four or five beers" plus shots at the campground; state recalled the deputy to rebut with testimony about alcohol absorption/elimination and how much alcohol would be required to reach .17% BAC.
- Defendant objected at trial that the testimony was scientific and lacked foundational support and that the deputy was not qualified to give such expert testimony; the trial court admitted the testimony.
- Jury convicted; defendant appealed arguing the testimony was scientific, required a scientific foundation, and the deputy lacked expert qualifications.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether deputy's testimony about absorption/elimination and retrograde extrapolation was scientific evidence requiring a special foundation | State: testimony is permissible lay/expert hybrid based on officer experience and training | Defendant: testimony was scientific (retrograde extrapolation/Widmark-type calculations) and required a scientific foundation | Held: Testimony was scientific and required a proper foundational showing |
| Whether the deputy was qualified as an expert to opine on absorption/elimination rates and perform retrograde calculations | State: deputy’s training (NHTSA), experience, and DUII investigations suffice | Defendant: deputy lacked requisite scientific training/education to perform formulaic, technical extrapolations | Held: Deputy was not qualified as an expert; record did not show sufficient expertise |
| Whether defendant preserved the evidentiary and qualification objections for appeal | State: objections not sufficiently specific to preserve | Defendant: trial objections (foundation/correlation/qualification) were sufficient | Held: Objections preserved; trial court understood the claims |
| Whether any error admitting the testimony was harmless | State: any error harmless given other evidence of intoxication | Defendant: testimony was key impeachment evidence undermining his trial account | Held: Error not harmless because testimony likely influenced jury verdict |
Key Cases Cited
- State v. Whitmore, 257 Or. App. 664 (trial court must require scientific validity foundation for retrograde extrapolation testimony)
- State v. Rambo, 250 Or. App. 186 (distinguishing lay opinion from scientific testimony about intoxication)
- State v. O'Key, 321 Or. 285 (scientific evidence requires showing that methods are scientifically valid)
- State v. Dunning, 245 Or. App. 582 (witness must qualify as an expert to offer scientific opinions)
- State v. Rogers, 330 Or. 282 (assessment of particular qualifications required under OEC 702)
Outcome: Reversed and remanded for proceedings consistent with opinion; deputy’s retrograde/extrapolation testimony was scientific, lacked proper foundation, and deputy was not shown to be qualified as an expert.
