297When leave to appeal may be given

297 When leave to appeal may be given (1) Subject to subsection (2), the Court of Appeal may give leave to appeal against an interlocutory decision only if the court is satisfied that it is in the interests of justice to do so, having regard to— (a) the extent of any disruption or delay to the trial process that may arise if leave is given; and (b) whether the determination of the appeal against the interlocutory decision may— (i) render the trial unnecessary; or (ii) substantially reduce the time required for the trial; or (iii) resolve an issue of law, evidence or procedure that is necessary for the proper conduct of the trial; or (iv) reduce the likelihood of a successful appeal against conviction in the event that the accused is convicted at trial; and (c) any other matter that the court considers relevant. (2) The Court of Appeal must not give leave to appeal after the trial has commenced, unless the reasons for doing so clearly outweigh any disruption to the trial. (3) If the Court of Appeal refuses leave to appeal under this section, the refusal does not preclude any other appeal on the issue that was the subject of the proposed appeal.
