The respondent pleaded guilty to unlawful confinement shortly before his trial.
His co-accused was subsequently acquitted of the same charge by a jury.
The respondent appealed to withdraw his guilty plea based on the co-accused's acquittal.
The Court of Appeal allowed the appeal and substituted an acquittal, finding the respondent could not have aided and abetted an offence that was not committed.
The Supreme Court of Canada allowed the Crown's appeal and reinstated the conviction, holding that the facts supported the respondent's conviction as a principal, and the acquittal of a co-accused is only conclusive between the Crown and that co-accused.
