R v Decuzzi

R. v. Decuzzi

2018 ONCJ 254
Ontario Court of Justice — Justice of the Peace Kenneth W. Dechert | April 13, 2018

Background

On February 9, 2017, Antonio Decuzzi was driving his grey Lexus SUV westbound on the QEW near Bronte Road when Police Constable Jonathan Cannon spotted him from two lanes away. Cannon was in lane 2, Decuzzi in lane 4 (the rightmost lane), traveling at highway speeds in moderately heavy traffic. For about 3-4 seconds, Cannon observed Decuzzi holding a black object in his right hand "slightly towards the centre of the vehicle, just below eye level." The officer identified it as a smartphone and pulled Decuzzi over.

Decuzzi was charged under section 78.1(1) of the Highway Traffic Act for driving while holding a hand-held wireless communication device. At trial, the only evidence was Cannon's testimony — no physical device was produced, as it was "out of plain sight" when the officer approached the vehicle after the stop.

Issues

1. Whether the prosecution proved beyond a reasonable doubt that the black object was a cell phone rather than another device
2. What weight should be given to a police officer's lay opinion identification of a device

The Identification Problem

The entire case hinged on Constable Cannon's ability to identify the black object as a cell phone. Under cross-examination, the officer's certainty cracked. He acknowledged that iPods and iPhones are "visually very similar" and "both essentially the same." When pressed whether the object could have been an iPod, he became equivocal: "I don't know that it was an i-pod or an i-phone" and "it appeared to be a phone."

Justice Dechert applied the legal principles from R. v. Graat and R. v. Cuming, noting that while lay opinion evidence about identification is admissible, there must be some evidential basis for the opinion before it can carry significant weight. The officer's observations were made from 20-25 feet away, across one lane of traffic, through two windows, while both vehicles traveled at highway speed — hardly optimal conditions for precise identification.

Crucially, the court referenced R. v. Mina, where Justice Allen quashed a similar conviction because the officer could only say the device "appeared to be" a cell phone. When an officer's identification is equivocal rather than certain, it substantially reduces the weight of their opinion evidence.

Key Takeaway

Police opinion evidence about device identification must be unequivocal and based on sufficient observation to prove guilt beyond a reasonable doubt.

If the prosecution can't distinguish between similar-looking devices or the officer expresses uncertainty during cross-examination, that creates reasonable doubt. The standard is "much closer to absolute certainty than to proof on a balance of probabilities" — and "probably a cell phone" isn't enough for a conviction.
