The respondent was convicted of failing to stop at a red light based on evidence from a red light camera system.
The justice of the peace refused the respondent's request to subpoena the provincial offences officer who issued the ticket.
On appeal, the judge ordered a new trial, holding that such requests should generally be granted.
The municipality appealed.
The Court of Appeal held that the appeal judge applied too liberal a standard; the defence must establish a reasonable and legitimate ground to question the officer.
However, the Court found the photographic evidence inadmissible because the required date, time, and location information was in an unexplained code, failing to comply with the regulation.
The appeal was allowed, but an acquittal was entered.
