Beachwood v. Joyner, 2012 Ohio 5884

Joyner was charged with speeding in a 35 mph zone in Beachwood under B.C.O. 434.03(b)(3) after a police radar reading of 57 mph.
Officer Lieb used a Kustom Pro-1000 moving radar while pursuing Joyner, and testified the device emitted an audible tone when speed exceeded 55 mph.
Joyner challenged the sufficiency of the evidence, arguing no expert testimony established the radar’s reliability or the officer’s certification.
The trial court found Joyner guilty and fined her $44 plus costs, relying on the radar reading and officer testimony.
Joyner appealed, contending the court improperly admitted radar evidence without expert proof and that visual estimation alone is inadequate post Jenney and RC 4511.091(C).
The appellate court reversed and remanded, holding the radar reading was inadmissible without expert testimony and that visual estimation alone could not sustain the conviction.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Radar reliability without expert testimony	Joyner argues the radar’s accuracy was not proven.	City contends judicial notice suffices for reliability.	Judicial notice insufficient; radar reliability requires expert testimony.
Admission of radar reading	Joyner asserts radar reading should have been excluded.	City maintains the reading was admissible evidence.	Radar reading improperly admitted without expert foundation.
Sufficiency of evidence without radar	Joyner contends evidence fails without radar reliability.	City relies on radar and officer testimony to prove speed.	No sufficient evidence to convict without reliable radar proof.
Officer’s visual estimation post Jenney and RC 4511.091(C)	Joyner argues visual estimation alone is insufficient post-law changes.	City argues visual estimation can sustain conviction with proper training.	Visual estimation alone is insufficient; statute prohibits unaided estimates for speeding convictions.
Certification of the officer to use radar	Joyner challenges lack of certification documentation.	City contends certification was shown through testimony.	Certification proof insufficient; requires proper evidentiary foundation.
