Mr. G. was referred to our office by his father a retired police officer. Mr. G. had been charged with impaired/.08 offences following an accident on his motorcycle. The collision was a serious one that required the attendance of emergency personnel. Following an examination by EMS the officers brought our client to the police station where breath sample readings exceeded 200 mg/%. After reviewing the evidence, it became apparent that no witnesses would be capable of establishing the time of driving, an essential prerequisite for admissibility of the Certificate of Analyst. The matter proceeded to trial where the Crown was put on notice of this fatal flaw. As the case was no longer salvageable the charges were withdrawn.
