At the hearing, counsel may use either "Justice", "Mr. Justice" or "Madam Justice," when addressing the members of the panel hearing the appeal. Counsel are asked to refrain from addressing the judges as "My Lord", "My Lady", "Your Lordship," or "Your Ladyship."
In writing, the Chief Justice is addressed as "The Right Honourable" and the other judges are addressed as "The Honourable Madame Justice" or as "The Honourable Mr. Justice".
