Narrative Opinion Summary
In this appellate case, the defendant contested a conviction for speeding under General Statutes 14-219 (a), arguing that the trial court erroneously admitted a document purporting to be a frequency calibration record for the radar device used to measure his speed. The defendant was stopped by state police on Route 2, with radar evidence corroborated by tuning fork tests that confirmed the device's accuracy. The court presumed that public officers, including the state police and commissioner, performed their duties properly unless proven otherwise. A contested letter from the Automatic Signal Division was admitted as a business entry under General Statutes 52-180, though its impact was determined to be non-prejudicial. The court emphasized that the appellant bears the burden of proving harmful error, which was not demonstrated given the corroborative evidence of the radar’s accuracy. Consequently, the court upheld the original conviction, concluding that the admission of the calibration document did not constitute a reversible error. Judges DiCenzo and Jacobs concurred with the decision, affirming the trial court's judgment.
