Federal Rules of Evidence (2015)
Rule 608. A Witness's Character for Truthfulness or Untruthfulness
(a) Reputation or Opinion Evidence. A witness's credibility may be attacked or supported by testimony about the witness's reputation for having a character for truthfulness or untruthfulness, or by testimony in the form of an opinion about that character. But evidence of truthful character is admissible only after the witness's character for truthfulness has been attacked.
(b) Specific Instances of Conduct.
Except for a criminal conviction under
Rule 609. Extrinsic evidence is not admissible to prove specific instances of a witness's conduct in order to attack or support the witness's character for truthfulness. But the court may, on cross-examination, allow them to be inquired into if they are probative of the character for truthfulness or untruthfulness of: (1) the witness; or (2) another witness whose character the witness being cross-examined has testified about.
By testifying on another matter, a witness does not waive any privilege against self-incrimination for testimony that relates only to the witness's character for truthfulness.
Rule 701. Opinion Testimony by Lay Witnesses
If a witness is not testifying as an expert, testimony in the form of an opinion is limited to one that is:
(a) rationally based on the witness's perception;
(b) helpful to clearly understanding the witness's testimony or to determining a fact in issue; and
(c) not based on scientific, technical, or other specialized knowledge within the scope of Rule 702.
Rule 702. Testimony by Expert Witnesses
A witness who is qualified as an expert by knowledge, skill, experience, training, or education may testify in the form of an opinion or otherwise if:
(a) the expert's scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue;
(b) the testimony is based on sufficient facts or data;
(c) the testimony is the product of reliable principles and methods; and
(d) the expert has reliably applied the principles and methods to the facts of the case.
Rule 703. Bases of an Expert's Opinion Testimony
An expert may base an opinion on facts or data in the case that the expert has been made aware of or personally observed. If experts in the particular field would reasonably rely on those kinds of facts or data in forming an opinion on the subject, they need not be admissible for the opinion to be admitted. But if the facts or data would otherwise be inadmissible, the proponent of the opinion may disclose them to the jury only if their probative value in helping the jury evaluate the opinion substantially outweighs their prejudicial effect.

Article 106 Video record evidence
(1) Without limiting section 105(1)(a)(iii), in a criminal proceeding, the video record evidence of a witness that is to be offered as an alternative way of giving evidence at the trial must, if a video record of that witness's evidence was filed as a formal statement under the Criminal Procedure Act 2011 or the witness gave oral evidence by way of a video record in accordance with an oral evidence order made under that Act, include that video record.
(2) A video record offered by the prosecution as an alternative way of giving evidence must be recorded and dealt with in compliance with any regulations made under this Act.
(3) A video record that is to be offered by the prosecution as an alternative way of giving evidence must be offered for viewing by a defendant or his or her lawyer before it is offered in evidence (including prior to any pre-trial consideration of admissibility), unless the Judge directs otherwise.
(4) A copy of a video record that is to be offered by the prosecution as an alternative way of giving evidence must be given to a defendant's lawyer unless subsection (4A) applies, or, if subsection (4A) does not apply, the Judge directs otherwise.
(4A) Subject to subsections (4B) and (4C), a defendant's lawyer is not entitled to be given a copy of a video record under subsection (4) of-
(a) any child complainant; or

(4B) On the application of a defendant, a Judge may order that a copy of a video record or a part of a video record to which subsection (4A) applies be given to the defendant's lawyer before it is offered in evidence.
(4C) When considering an application under subsection (4B), the Judge must have regard to-
(a) whether the interests of justice require departure from the usual procedure under subsection (4A) in the particular case; and
(b) the nature of the evidence contained on the video record; and
(c) the ability of the defendant or his or her lawyer to view the video record under subsection (3) and to otherwise access the content of the video record, including by way of a transcript of the video record.
(5) All parties must be given the opportunity to make submissions about the admissibility of all or any part of a video record that is to be offered as an alternative way of giving evidence.

(7) The Judge may order to be excised from a video record offered as evidence any material that, if the evidence were given in the ordinary way, would or could be excluded in accordance with this Act.
(8) The Judge may admit a video record that is recorded and offered as evidence substantially in accordance with the terms of any direction under this subpart and the terms of regulations referred to in subsection (2), despite a failure to observe strictly all of those terms.
(9) To avoid doubt, subsections (3) to (4C) do not apply to any lawyer representing the Crown who may be given a copy of a video record (which may or may not be offered as an alternative way of giving evidence) at any time for the purpose of providing legal advice to the Police before a charging document is filed and for conducting the prosecution once proceedings have commenced.
