The appellant was charged with robbery and using a firearm.
During the preliminary inquiry, the appellant re-elected to be tried by a magistrate.
The magistrate granted the motion, took a plea, and continued the proceedings as a trial.
However, the evidence adduced prior to the re-election was inadvertently not read into the trial record.
The Supreme Court of Canada held that an accused can only be convicted on evidence legally adduced before the trier of fact during the trial.
Since the preliminary inquiry evidence was not read into the record, the conviction could not stand.
The appeal was allowed and a new trial ordered.
