R v Giacomelli

R. v. Giacomelli

[2008] O.J. No. 5701
Ontario Court of Justice — C.P. Mutuma J.P. | October 6, 2008

Background

On New Year's Day 2007 at 11:39 a.m., Fabrizio Giacomelli was allegedly caught speeding on Bay Avenue in Toronto. The officer clocked him doing 87 km/h in a 50 km/h zone using laser equipment — a significant violation of 37 km/h over the limit under section 128 of the Highway Traffic Act.

The officer testified that he was properly trained on the laser device, had tested it before and after use according to manufacturer specifications, and regularly worked that same location. The prosecution seemed to have a solid case with clear evidence of excessive speeding.

Issues

1. Whether the laser evidence was reliable and properly obtained
2. Whether inconsistencies in the officer's testimony undermined the Crown's case

The Cross-Examination Strategy

Rather than attacking the reliability of the laser itself, Giacomelli's agent focused on the officer's training process and note-taking practices. During cross-examination, the agent exposed "areas that were rather inconsistent" in the officer's testimony. The court noted problems with information "not included in the notes but provided through the use of the memory by the officer."

Justice Mutuma found the officer credible regarding his general work practices and daily operations of the laser equipment. There was no dispute about the actual speed reading of 87 km/h. However, the inconsistencies that emerged during cross-examination about the officer's notes and memory were significant enough to undermine the prosecution's case entirely.

Key Takeaway

Even rock-solid technical evidence can be defeated if the officer's testimony contains inconsistencies during cross-examination.

This case shows that challenging an officer's note-taking practices and memory can be an effective defence strategy, even when the underlying technical evidence appears strong. Preparation for cross-examination on these procedural details can create reasonable doubt.
