22.1 In an appeal against conviction, a prosecutor’s duty is to assist the court to achieve a just and proper disposal of the appeal. It requires the prosecutor to readily and promptly seek to remedy any error or injustice and with equal commitment seek to support a correct and proper decision of the trial court.
22.2 If an appellant is unrepresented, a prosecutor should examine the case to see if any unidentified ground of appeal might also be available.
22.3 Ordinarily a prosecutor will seek to have the conviction upheld; but if it becomes apparent that there is a proper basis for conceding an appeal, that should be explained to the court. Such a concession should be made with the consent of the Director of Public Prosecutions in appropriate cases.

22.11 Section 84 of the District Court Ordinance, Cap 336 and section 105 of the Magistrates Ordinance, Cap 227 enable the Secretary for Justice to appeal to the Court of Appeal and the Court of First Instance respectively by way of Case Stated from a decision of the trial judge or magistrate. This is an exceptional course and will only be undertaken when the determination or verdict or order of acquittal was erroneous in point of law.
