Evidence Bill (1)

The exercise of judgment is fundamental to the application of the rules of evidence. There are 4 areas in which judgment is critical:

 The decision whether to exercise the discretion to exclude evidence on public policy grounds. The focus here is on unreliable confessions, statements obtained by oppression, and other kinds of improperly obtained evidence.

 The decision whether to admit evidence that would otherwise be inadmissible, where its probative value outweighs the risk of illegitimate prejudice to the accused. Evidence of bad character is the prime example of evidence of this kind.

 Decisions that have to be made concerning the requirements of fairness. The choice is between excluding the evidence and admitting it with a warning to the jury about its dangers. Examples are evidence that is of questionable reliability, delayed complaints of sexual misconduct, evidence of children, identification evidence, and evidence that the accused has told lies.

 Decisions that have to be made with a view to avoiding a substantial miscarriage of justice. Usually an appellate court will be in a position to have a better perspective on this than will the trial judge, but nevertheless a trial judge will bear this requirement in mind throughout the trial. The need here is to avoid two kinds of errors: errors through which the accused improperly loses a chance of acquittal that should have been reasonably open, and errors which cause the jury to misapply the law to the facts.

I will consider, in separate blog entries, how each of these areas of judicial judgment are to operate under the Evidence Bill, which was introduced into Parliament this month. Today I begin with …

The Public Policy Decisions

The Bill sets out three rules: the unreliable statement rule (Clause 24), the oppression rule (cl 25) and the improperly obtained evidence rule (cl 26). The first two require the judge to evaluate the evidence on the relevant issue against the standard of either (cl 24(2)) the balance of probabilities, or (cl 25(2)) beyond reasonable doubt. The third, however, involves both judgment against a standard (the balance of probabilities: cl 26(2)(a)) and a balancing exercise to determine whether exclusion is proportionate to the impropriety: cl 26(2)(b).

24 Exclusion of unreliable statements

(1) This section applies to a criminal proceeding in which the prosecution offers or proposes to offer a statement of a defendant if---
(a) the defendant or a co-defendant against whom the statement is offered raises, on the basis of an evidential foundation, the issue of the reliability of the statement and informs the Judge and the prosecution of the grounds for raising the issue; or

(b) the Judge raises the issue of the reliability of the statement and informs the prosecution of the grounds for raising the issue.

(2) The Judge must exclude the statement unless satisfied on the balance of probabilities---

(a) that the circumstances in which the statement was made were not likely to have adversely affected its reliability; or

(b) that the statement is true.

(3) However, subsection (2) does not have effect to exclude a statement made by a defendant if the statement is offered only as evidence of the physical, mental, or psychological condition of the defendant at the time the statement was made or as evidence of whether the statement was made.

(4) Without limiting the matters that a Judge may take into account for the purpose of applying subsection (2)(a), the Judge must, in each case, take into account any of the following matters that are relevant to the case:

(a) any pertinent physical, mental, or psychological condition of the defendant when the statement was made (whether apparent or not); and

(b) any pertinent characteristics of the defendant including any mental, intellectual, or physical disability to which the defendant is subject (whether apparent or not); and

(c) the nature of any questions put to the defendant and the manner and circumstances in which they were put; and

(d) the nature of any threat, promise, or representation made to the defendant or any other person.


25 Exclusion of statements influenced by oppression

(1) This section applies to a criminal proceeding in which the prosecution offers or proposes to offer a statement of a defendant if---

(a) the defendant or a co-defendant against whom the statement is offered raises, on the basis of an evidential foundation, the issue of whether the statement was influenced by oppression and informs the Judge and the prosecution of the grounds for raising the issue; or

(b) the Judge raises the issue of whether the statement was influenced by oppression and informs the prosecution of the grounds for raising the issue.

(2) The Judge must exclude the statement unless satisfied beyond reasonable doubt that the statement was not influenced by oppression.

(3) For the purpose of applying this section, it is irrelevant whether or not the statement is true.

(4) Without limiting the matters that a Judge may take into account for the purpose of applying subsection (2), the Judge must, in each case, take into account any of the following matters that are relevant to the case:

(a) any pertinent physical, mental, or psychological condition of the defendant when the statement was made (whether apparent or not); and

(b) any pertinent characteristics of the defendant including any mental, intellectual, or physical disability to which the defendant is subject (whether apparent or not); and

(c) the nature of any questions put to the defendant and the manner and circumstances in which they were put; and

(d) the nature of any threat, promise, or representation made to the defendant or any other person.

(5) In this section, oppression means---

(a) oppressive, violent, inhuman, or degrading conduct towards, or treatment of, the defendant or another person; or

(b) a threat of conduct or treatment of that kind.


26 Improperly obtained evidence

(1) This section applies to a criminal proceeding in which the prosecution offers or proposes to offer evidence if---

(a) the defendant or a co-defendant against whom the evidence is offered raises, on the basis of an evidential foundation, the issue of whether the evidence was improperly obtained and informs the prosecution of the grounds for raising the issue; or

(b) the Judge raises the issue of whether the evidence was improperly obtained and informs the prosecution of the grounds for raising the issue.

(2) The Judge must---

(a) find, on the balance of probabilities, whether or not the evidence was improperly obtained; and

(b) if the Judge finds that the evidence has been improperly obtained, determine whether or not the exclusion of the evidence is proportionate to the impropriety by means of a balancing process that gives appropriate weight to the impropriety but also takes proper account of the need for an effective and credible system of justice.

(3) For the purposes of subsection (2), the court may, among any other matters, have regard to the following:

(a) the importance of any right breached by the impropriety and the seriousness of the intrusion on it:

(b) the nature of the impropriety, in particular, whether it was
deliberate, reckless, or done in bad faith:

(c) the nature and quality of the improperly obtained evidence, in
particular whether it is central to the case of the prosecution:

(d) the seriousness of the offence with which the defendant is charged:

(e) whether there were any other investigatory techniques not involving any breach of the rights that were known to be available but were not used:

(f) whether there are alternative remedies to exclusion of the evidence which can adequately provide redress to the defendant:

(g) whether the impropriety was necessary to avoid apprehended physical danger to the police or others:

(h) whether there was any urgency in obtaining the improperly obtained evidence.

(4) The Judge must exclude any improperly obtained evidence if, in
accordance with subsection (2), the Judge determines that its exclusion is proportionate to the impropriety.

(5) For the purposes of this section, evidence is improperly obtained if it is obtained---

(a) in consequence of a breach of any enactment or rule of law by a person to whom section 3 of the New Zealand Bill of Rights Act 1990 applies; or

(b) in consequence of a statement made by a defendant that is or would be inadmissible if it were offered in evidence by the prosecution; or

(c) unfairly.


Of interest here are the standards of proof specified for each decision. Clause 24 uses the balance of probabilities. The Law Commission has changed its stance: in the Evidence Code (NZLC R 55 vol 2) the corresponding clause, 27(2), used beyond reasonable doubt as the standard for excluding unreliability. Of course here “unreliability” is a shorthand way of referring to the question whether the circumstances in which the statement was obtained were likely to affect its reliability. This is distinct from the question of the actual reliability of the statement itself. There is therefore not the logical objection that otherwise would lie in the way of the criminal standard of proof applying (the objection would have been that if the statement was, beyond reasonable doubt, reliable, the ultimate issue would have been decided by the judge). Bearing in mind the point that the issue is the circumstances in which the evidence was obtained, the focus is on the propriety of the methods used to obtain it. The Bill does not insist on proof to the standard of beyond reasonable doubt that those who obtained the statement acted properly.

The criminal standard of proof is applied to the issue of absence of oppression in cl 25. This properly reflects the common law’s abhorrence of “third degree” interrogations.

The balance of probabilities is applied in cl 26 as a threshold that has to be met before the balancing exercise is undertaken. Unless the defence satisfies the judge on the balance of probabilities that there was impropriety in the obtaining of the evidence, there is no progression to the balancing exercise, and the evidence is not excluded on that ground. Use of the balance of probabilities here is a reflection of the commonly held view that any factual pre-conditions that have to be established before evidence is admissible need only be proved on the balance of probabilities. Early formulations of the now obsolete prima facie exclusion rule, that applied to evidence obtained in breach of the Bill of Rights, used the same standard of proof on the issue of whether there had been a breach. The prima facie exclusion rule was replaced in R v Shaheed [2002] 2 NZLR 377 (CA) by the balancing exercise which is reflected in cl 26(2)(b) and (3) of the Bill. Under Shaheed the balancing exercise was not expressly contingent on the satisfaction of any particular standard of proof applicable to the issue of whether there had been a breach of rights. In contrast, the Privy Council, in Mohammed v The State [1999] 2 AC 111, 123-124, held that where there is an issue of the breach of rights, the prosecution bears the burden of excluding such breach to the standard of beyond reasonable doubt, and that where the prosecution fails to achieve that, the balancing exercise must be undertaken (except where the breach is of the right to a fair trial, in which case the evidence is automatically excluded without balancing).

In these contexts, the standard of proof is an expression of how willing the court will be to look at the issue the defence seeks to raise. Oppression is, under the scheme in the Bill, the most eagerly examined. Unreliability and impropriety do not attract as much interest. The appropriateness of those thresholds for judicial interest is a matter over which people may well differ.
