The three accused were charged with robbery with a firearm and related offences.
At their jury trial, the sole Crown witness claimed complete memory loss.
The Crown sought to introduce her preliminary hearing transcript.
The trial judge ruled the transcript admissible but subject to strong Vetrovec warnings.
Recognizing the severe prejudice to the defence, who had elected a jury trial expecting to cross-examine the witness, the judge allowed the accused to re-elect a judge-alone trial, finding the Crown's refusal to consent to the re-election was an abuse of process.
Sitting as a judge alone, the trial judge found the witness's uncorroborated evidence insufficient and acquitted all accused.
