Constable Wong appealed a finding of misconduct and a penalty of a one-day suspension without pay for making an unlawful arrest during the G20 Summit.
The public complainant also appealed the penalty, arguing it was inadequate.
The Ontario Civilian Police Commission found that the Hearing Officer erred in law regarding the burden of proof and the essential elements of the misconduct charge.
However, the Commission exercised its power to substitute its own decision, finding that the evidence supported the misconduct charge on a balance of probabilities.
The Commission upheld the one-day suspension penalty as reasonable.
