Coincidence evidence and the Uniform Evidence Law
undamental to the concept of ‘fair trial’ is the balance to be struck by the
trial judge between allowing the Crown to prove its case with evidence of
F wrongdoing and a defendant’s right to have evidence excluded for
prejudice. The rules of evidence guide the trial judge in achieving that balance.
One such rule that governs the reception of evidence in those Australian jurisdic-
tions that have adopted the Australian Uniform Evidence Law (UEL) is the
coincidence rule. This rule applies to evidence that is used to prove that an
individual did an act or had a state of mind on the basis that it was improbable
that two or more similar events occurred coincidentally. Ordinarily, evidence of
this nature is inadmissible unless the ‘court thinks that the evidence will, either by
itself or having regard to other evidence adduced or to be adduced by the party
seeking to adduce the evidence, have significant probative value’.1
Prior to the introduction of the UEL in New South Wales in the form of the
Evidence Act 1995 (NSW), evidence of this type was regulated at common law as

intending to adduce such evidence give written notice of its intention to do so: s. 98(1)(a).

‘similar fact evidence’ or ‘propensity evidence’.2 The common law rules relating to
similar fact evidence continue to be applied in some non-UEL jurisdictions.3
Australian common law draws on the decisions of the House of Lords on this issue,
namely, Makin v Attorney-General for New South Wales,4 R v Boardman5 and DPP v P.6 In
DPP v P, Lord Mackay stated that ‘the essential feature of evidence which is to be
admitted is that its probative force in support of the allegation that an accused
person committed a crime is sufficiently great to make it just to admit the
evidence, notwithstanding that it is prejudicial to the accused in tending to show
that he was guilty of another crime’.7
Those rules were reiterated in the Australian context in Pfennig v The Queen in
which it was stated that probative value is to be balanced against prejudicial effect
and that ‘the evidence ought not to be admitted if the trial judge concludes that,
viewed in the context of the prosecution case, there is a reasonable view of it
which is consistent with innocence’.8 That rule is also subject to the qualification
that prior to getting that far, it must be established that the evidence is relevant.9
The common law rules continued to govern the admission of similar fact evidence
(which had long been a component of ‘bad character’)10 in England and Wales
until the introduction of the Criminal Justice Act 2003. That Act abolished the
common law rules in relation to evidence of bad character,11 and established a
statutory ‘gateway’ for the reception of such evidence.12 The Act was intended to
bring about a ‘sea change’ in the law.13 The common law took an exclusionary
approach, subject to the inclusionary exception where the probative value was
such that it outweighed the significant risk of unfair prejudice. The statutory
scheme established by the Act reverses this approach, so that provided bad

CASE NOTE
character is relevant to an important matter in issue between the defendant and
the prosecution, it is prima facie admissible.14 However, this presumption is
qualified by a provision requiring exclusion where reception of the evidence
would have an adverse impact on the fairness of the proceedings.15 In this respect,
the provisions of the UEL bear closer resemblance to the common law that they
replaced.16 The general position is that coincidence evidence is inadmissible,
although this is subject to an inclusionary exception for evidence that has ‘signif-
icant probative value’.17
Under the UEL, the first criterion for the admission of any evidence is that it must
be relevant,18 that is, it must be capable of ‘rationally affect[ing] (directly or
indirectly) the assessment of the probability of the existence of a fact in issue’.
Probative value is defined in the Dictionary in substantially identical terms,19
indicating that an assessment of probative value is a ‘question of relevance’.20 In
this respect, the UEL reflects the relevance requirements at common law,21 albeit
that whereas relevance is an absolute,22 probative value is assessed on a
continuum.23 In terms of the admission of evidence for a coincidence purpose
under s. 98, however, more is required than mere relevance. Whereas previously a
balancing exercise between probative force and prejudicial effect was required,
now, coincidence evidence is admissible if it has ‘significant probative value’.24
Prejudicial effect is still considered in relation to criminal proceedings by way of s.
101 of the Evidence Act 1995, insofar as the probative value of the evidence must
‘substantially outweigh’ the prejudicial effect, but there is now a degree of
separation between the two considerations. The UEL is silent on the question of
how significant probative value is to be determined. The position at common law
retains substantial relevance in this respect.25 For example, the similarity between
the events and the number of alleged instances will need to be considered in
