114 N.E.3d 594
Oh. Ct. App. 4th Dist. Scioto2018Background
- Juvenile Z.E.N. was charged as a juvenile traffic offender for driving 70 mph in a 50 mph zone in Scioto County, Ohio.
- At the bench trial, Trooper Johnson testified he visually observed the speeding and confirmed it with an LTI 20-20 laser unit; he said the unit was calibrated and he was trained.
- The State introduced no expert testimony establishing the LTI 20-20's scientific reliability, nor did the trial court take judicial notice of the device's reliability; Z.E.N. did not object at trial but her counsel argued lack of foundation in closing.
- The trial court found Z.E.N. a juvenile traffic offender based on the trooper’s testimony and the laser reading and entered adjudication and costs.
- On appeal the court considered (1) whether laser-device evidence without proof of scientific reliability suffices to support a speeding adjudication, and (2) whether the trooper’s unaided visual estimation could independently support conviction given statutory limits.
Issues
| Issue | Plaintiff's Argument (State) | Defendant's Argument (Z.E.N.) | Held |
|---|---|---|---|
| Sufficiency of laser evidence | Trooper testified to calibration and training; laser reading supports speed | State failed to introduce evidence of the LTI 20-20’s scientific reliability | Reversed: laser reading without proof of scientific reliability (expert testimony or judicial notice) did not supply sufficient evidence |
| Waiver/plain error | No timely objection at trial; error waived | Lack of foundation is plain error affecting sufficiency and may be raised on appeal | Plain error: failure to prove scientific reliability implicated sufficiency despite no contemporaneous objection |
| Reliance on officer’s visual estimate | Trooper also visually estimated the car was well over limit | Visual estimate can be sufficient per Barberton if officer trained/experienced | Rejected: R.C. 4511.091(C)(1) now bars convictions based solely on unaided visual estimates for R.C. 4511.21(D) offenses; visual estimate could not save the conviction here |
| Harmless error | Any error harmless because of visual observation | Lack of lawful independent basis (laser unreliable, visual estimate precluded) made error prejudicial | Not harmless: conviction reversed and defendant to be discharged |
