Procedural Posture

Criminal / Conviction Appeal (court of Appeal)

  1. 1 Whether a forensic accountant employed by a regulatory body is disqualified from giving expert opinion evidence due to lack of independence or impartiality
  2. 2 Whether the Rowbotham prerequisites for state-funded counsel were met (refusal of legal aid, lack of means, essential for a fair trial)
  3. 3 Whether the evidence was sufficient to support a conviction for fraud over $5,000

Ratio Decidendi

An expert's prior connection to an investigation does not per se disqualify them; admissibility depends on context and usually impacts weight rather than admissibility, and here Deverteuil's factual tracing evidence was admissible while any limited opinion evidence was inconsequential; the Rowbotham application was properly dismissed because the appellant failed to demonstrate lack of means due to non-disclosure; the conviction was supported by overwhelming evidence of fraud and is upheld.

Court Disposition

Appeal dismissed; conviction upheld
