R v Koumoudouros

R. v. Koumoudouros

[2005] O.J. No. 5055
Ontario Court of Justice — B. Zabel J. | May 17, 2005

Background

Branita Koumoudouros was charged with speeding under the Highway Traffic Act. The police officer used the speedometer in his own patrol vehicle to pace her speed — a method where the officer follows behind and matches the defendant's speed using his cruiser's speedometer as the measuring device. At trial, the officer testified that his speedometer was "certified and calibrated" but couldn't provide any details about who did the certification, when it was done, or any documentation proving it.

The defence lawyer, represented by agent Frank Alfano, cross-examined the officer extensively on this point. The officer admitted he didn't know who certified the speedometer, couldn't say when it was calibrated, didn't know how old the vehicle was, and had no certificate or documentation — just that he was "told it's a certified calibrated speedometer" and had "no reason to doubt that information." Despite this cross-examination revealing these gaps, the justice of the peace convicted Koumoudouros, stating she had "no reason to doubt" the officer's belief that the speedometer was working properly.

Issues

1. Whether the officer's unsupported testimony that the speedometer was "certified and calibrated" was sufficient proof beyond a reasonable doubt
2. Whether the justice of the peace erred in law by ignoring the reasonable doubt established through cross-examination

The Speedometer Certification Problem

This case hinges on a fundamental evidentiary principle: the prosecution must prove every element of their case beyond a reasonable doubt. When police use speedometers for pacing, they need to establish that the device is accurate. The Crown argued that speedometers are presumed accurate unless there's evidence to the contrary, relying on cases like Bland.

However, Justice Zabel found this case distinguishable from Bland. In Bland, there was actually a certificate showing the speedometer had been tested against radar equipment, with documentation of when it was done and how many kilometres the vehicle had travelled since calibration. Here, there was literally nothing — no certificate, no testing records, no knowledge of when any calibration might have occurred.

The court emphasized that once the defence cross-examined the officer and exposed these fundamental gaps in his knowledge, a reasonable doubt was established. The officer couldn't answer basic questions: Who certified it? When? Where's the certificate? How long ago? The justice of the peace erred in law by simply accepting the officer's bare assertion and ignoring the doubt created by cross-examination.

Key Takeaway

Effective cross-examination can expose fatal weaknesses in seemingly routine police evidence.

When facing speedometer pacing cases, defendants should probe the officer's knowledge about calibration and certification. If the officer can't provide specifics about when, how, or by whom the speedometer was certified, this may establish reasonable doubt about the accuracy of the speed measurement, even without calling defence evidence.
