Part 5 Miscellaneous provisions
Article 34
(1) An accused shall not call an expert witness or adduce expert evidence unless leave to do so has been granted under this section.
(2) Where the defence intends to call an expert witness or adduce expert evidence, whether or not in response to such evidence presented by the prosecution, notice of the intention shall be given to the prosecution at least 10 days prior to the scheduled date of the start of the trial.
(3) A notice under subsection (2) shall be in writing and shall include—
(a) the name and address of the expert witness, and
(b) any report prepared by the expert witness concerning a matter relevant to the case, including details of any analysis carried out by or on behalf of, or relied upon by, the expert witness, or a summary of the findings of the expert witness.
(4) The court may grant leave to call an expert witness or adduce expert evidence even if no report or summary of the findings are included as required by subsection (3)(b), if the court is satisfied that the accused took all reasonable steps to secure the report or summary before giving the notice.
(5) The court shall grant leave under this section to call an expert witness or adduce expert evidence, on application by the defence, if it is satisfied that the expert evidence to be adduced satisfies the requirements of any enactment or rule of law relating to evidence and that—
(a) subsections (2) and (3) have been complied with,
(b) where notice was not given at least 10 days prior to the scheduled date of the start of the trial, it would not, in all the circumstances of the case, have been reasonably possible for the defence to have done so, or
(c) where the prosecution has adduced expert evidence, a matter arose from that expert’s testimony that was not reasonably possible for the defence to have anticipated and it would be in the interests of justice for that matter to be further examined in order to establish its relevance to the case.
(6) The prosecution shall be heard in an application under subsection (4) or (5).
(7) A notice required by this section to be given to the prosecution may be given by delivering it to the prosecutor, or by leaving it at his or her office or by sending it by registered post to his or her office.
(8) Where the court grants leave under this section, the prosecution shall be given a reasonable opportunity to consider the report or summary before the expert witness gives the evidence or the evidence is otherwise adduced.
(9) In this section—
“expert evidence” means evidence of fact or opinion given by an expert witness, and
“expert witness” means a person who appears to the court to possess the appropriate qualifications or experience about the matter to which the witness's evidence relates.
1. Before testifying, each witness shall, in accordance with the Rules of Procedure and Evidence, give an undertaking as to the truthfulness of the evidence to be given by that witness.
2. The testimony of a witness at trial shall be given in person, except to the extent provided by the measures set forth in article 68 or in the Rules of Procedure and Evidence. The Court may also permit the giving of viva voce (oral) or recorded testimony of a witness by means of video or audio technology, as well as the introduction of documents or written transcripts, subject to this Statute and in accordance with the Rules of Procedure and Evidence. These measures shall not be prejudicial to or inconsistent with the rights of the accused.
3. The parties may submit evidence relevant to the case, in accordance with article 64. The Court shall have the authority to request the submission of all evidence that it considers necessary for the determination of the truth.
4. The Court may rule on the relevance or admissibility of any evidence, taking into account, inter alia, the probative value of the evidence and any prejudice that such evidence may cause to a fair trial or to a fair evaluation of the testimony of a witness, in accordance with the Rules of Procedure and Evidence.
5. The Court shall respect and observe privileges on confidentiality as provided for in the Rules of Procedure and Evidence.
6. The Court shall not require proof of facts of common knowledge but may take judicial notice of them.
7. Evidence obtained by means of a violation of this Statute or internationally recognized human rights shall not be admissible if:
(a) The violation casts substantial doubt on the reliability of the evidence; or
(b) The admission of the evidence would be antithetical to and would seriously damage the integrity of the proceedings.
8. When deciding on the relevance or admissibility of evidence collected by a State, the Court shall not rule on the application of the State's national law.
