Mitchell v. State
301 Ga. 563
| Ga. | 2017Background
- Mitchell stopped after an officer observed lane deviation; officer detected strong odor of alcohol, slurred speech, bloodshot/glassy eyes, and difficulty with his license. Mitchell initially refused to exit vehicle and to perform field sobriety tests.
- A second officer told Mitchell he could either get out voluntarily or be removed; Mitchell exited, swayed and leaned on the car, then initially refused tests but ultimately agreed after the officer told him he would be arrested if he did not submit.
- Officers administered HGN, walk-and-turn, and Romberg-style balance/time-estimation tests; officer reported maximum clues on HGN and walk-and-turn, and that Mitchell exceeded the Romberg time window and exhibited swaying and eyelid tremors.
- Mitchell moved to suppress field sobriety results and in limine to exclude their admission; he also challenged OCGA § 24-7-707 (expert testimony rules) on equal protection and separation-of-powers grounds.
- At the suppression hearing officers testified and dashcam video was played; trial court denied motions and certified the order for immediate appellate review.
Issues
| Issue | Mitchell's Argument | State's Argument | Held |
|---|---|---|---|
| Whether Romberg test is a "scientific" test requiring Harper foundation | Romberg involves non-obvious scientific principles (internal clock, eyelid tremors) and requires validation under Harper | Romberg is a lay-observable balance/dexterity test not subject to Harper | Court: Romberg requires Harper foundation; trial court erred by not applying Harper analysis |
| Whether Miranda warnings were required before officer threatened arrest to compel tests | Officer’s threat to arrest made Mitchell effectively in custody, so Miranda required and failure to give warnings should suppress tests | Officer’s statements left open the possibility of temporary detention; a reasonable person wouldn’t have felt under arrest | Court: No Miranda violation; reasonable person would not have believed detention was non-temporary; suppression denial affirmed |
| Whether refusal to submit to field sobriety tests is a Fourth Amendment "search" whose refusal cannot be used against defendant | Refusal to submit is analogous to refusal to consent to warrantless property search (Mackey) and should be protected | Field sobriety tests are non-search exemplars (like handwriting/voice); refusal is not protected in same way | Court: Field sobriety tests are not Fourth Amendment searches; trial court properly allowed evidence of refusal |
| Whether OCGA § 24-7-707 violates equal protection or separation of powers | Statute treats criminal expert testimony differently from civil; violates equal protection/separation of powers | Precedent upholds statutory evidentiary rules; statute is constitutional and within legislative authority | Court: Statute constitutional under precedent (declined to overrule Mason); challenges rejected |
