(1)  On an appeal the Court shall allow the appeal if it is of opinion that the verdict of the jury should be set aside on the ground that it is unreasonable, or cannot be supported having regard to the evidence, or that the judgment or order of the court of trial should be set aside on the ground of the wrong decision of any question of law, or that on any ground whatsoever there was a miscarriage of justice, and in any other case shall dismiss the appeal.

(2)  The Court may, notwithstanding that it is of the opinion that the point raised by the appeal might be decided in favour of the appellant, dismiss the appeal if it considers that no substantial miscarriage of justice has actually occurred.

(3)  Subject to the special provisions of this chapter, the Court shall, if it allows an appeal against conviction, quash the conviction and direct a judgment and verdict of acquittal to be entered.

(4)  On an appeal against a sentence, the Court, if it is of opinion that some other sentence, whether more or less severe, is warranted in law and should have been passed, shall quash the sentence and pass such other sentence in substitution therefor, and in any other case shall dismiss the appeal.

(4A)  The Court, on hearing an appeal against a sentence passed on a person for an offence (whether the appeal was brought, made or lodged by the person or by the prosecutor), may take into account any matter relevant to the sentence that has occurred between when the court of trial dealt with the person and when the appeal is heard.

(4B)  Despite subsection (4A) , the Court, in passing another sentence under subsection (4) , must not take into account the element of double jeopardy involved in the person being sentenced again, in order to pass a less severe sentence than the Court would otherwise consider appropriate.

(4C)  Despite subsection (4) , on an appeal against a sentence the Court may, if it thinks that it is appropriate and in the interests of justice to do so, quash the sentence passed at the trial and remit the matter to the court of trial.

(4D)  If the Court quashes a sentence passed at a trial and remits the matter to the court of trial under subsection (4C)  –

(a) it may give any directions that it thinks fit concerning the manner and scope of the further hearing of the matter by the court of trial, including a direction as to whether that hearing is to be conducted by the same judge as, or a different judge to, the judge that passed the sentence; and

(b) the court of trial must hear and determine the matter in accordance with the law and any such directions; and

(c) the court of trial may take into account any matter relevant to sentencing that has occurred between when the court of trial passed the quashed sentence and when the court of trial decides the remitted matter; and

(d) despite paragraph (c) , the court of trial must not take into account the element of double jeopardy involved in the person being sentenced again, so as to pass a less severe sentence than the court of trial would otherwise consider appropriate.

(5)  If the Court allows an appeal against an order arresting judgment or against an acquittal, it may make any of the following orders which may be applicable:

(a) that judgment be pronounced upon the offender;

(b) that a conviction be entered against the offender;

(c) that a venire de novo or new trial shall be had in such manner as the Court may direct;

(d) that the offender shall appear at such time and place as the Court may direct to receive judgment –

and any justice may thereupon issue his warrant for the arrest of the offender.

(6)  Any offender so arrested may be admitted to bail by order of the Court or a judge.

(7)  The Court may dismiss an appeal at any time, either on its own motion or on the application of either party to the appeal, if it is satisfied that –

(a) the appellant has failed to take all reasonable steps to prosecute the appeal; and

(b) it is necessary or expedient in the interests of justice to do so.
