3.—(1) On the hearing of an appeal against conviction of an offence the Court may—

(a) affirm the conviction (and may do so, notwithstanding that it is of opinion that a point raised in the appeal might be decided in favour of the appellant, if it considers that no miscarriage of justice has actually occurred), or

(b) quash the conviction and make no further order, or

(c) quash the conviction and order the applicant to be re-tried for the offence, or

(d) quash the conviction and, if it appears to the Court that the appellant could have been found guilty of some other offence and that the jury must have been satisfied of facts which proved him guilty of the other offence—

(i) substitute for the verdict a verdict of guilty of the other offence, and

(ii) impose such sentence in substitution for the sentence imposed at the trial as may be authorised by law for the other offence, not being a sentence of greater severity.

(2) On the hearing of an appeal against sentence for an offence the Court may quash the sentence and in place of it impose such sentence or make such order as it considers appropriate, being a sentence or order which could have been imposed on the convicted person for the offence at the court of trial.

(3) The Court, on the hearing of an appeal or, as the case may be, of an application for leave to appeal, against a conviction or sentence may—

(a) where the appeal is based on new or additional evidence, direct the Commissioner of the Garda Síochána to have such inquiries carried out as the Court considers necessary or expedient for the purpose of determining whether further evidence ought to be adduced;

(b) order the production of any document, exhibit or other thing connected with the proceedings;

(c) order any person who would have been a compellable witness in the proceedings from which the appeal lies to attend for examination and be examined before the Court, whether or not he was called in those proceedings;

(d) receive the evidence, if tendered, of any witness;

(e) generally make such order as may be necessary for the purpose of doing justice in the case before the Court.

(4) For the purposes of this section, the Court may order the examination of any witness whose attendance might be required under this section to be conducted, in a manner provided by rules of court, before any judge or officer of the Court or other person appointed by the Court for the purpose, and allow the admission of any depositions so taken as evidence before the Court.

(5) The reference in subsection (1) (d) to a jury shall, where the trial was before a court sitting without a jury, be construed as a reference to that court.

(6) Section 32 of the Courts of Justice Act, 1924, is hereby amended by the addition after “pending the determination of his appeal” of “or application for leave to appeal”.

(7) A legal aid certificate which was granted in relation to the trial of an accused person who has been ordered by the Court under this section to be re-tried shall have effect as if it had been granted also in relation to his re-trial.

(8) The references in section 44 (2) of the Offences Against the State Act, 1939, to section 34 of the Criminal Justice Act, 1924, and section 5 of the Criminal Justice Act, 1928, shall be construed as references to this section.
