"In MacKenzie v The Queen, Gaudron, Gummow and Kirby JJ stated a number of general propositions concerning the significance that may properly be attached to what is sometimes referred to as factual inconsistency between verdicts. In that respect, it is to be noted that, where an accused is charged with multiple offences, differences between the verdicts may not, in truth, involve inconsistencies even of a factual kind. In the present case, if there had been a verdict of guilty on count 2 and not guilty on count 3, where the charges were supported by substantially the same evidence, then there would have been factual, even though not technical or legal, inconsistency. However the evidence in support of counts 7 and 8 was materially different from the evidence in relation to counts 1-6 and count 9. The complainant was, to a significant extent, supported by MA.
Since the ultimate question concerns the reasonableness of the jury's decision, the significance of verdicts of not guilty on some counts in an indictment must necessarily be considered in the light of the facts and circumstances of the particular case. Furthermore, it must be considered in the context of the system within which juries function and of their role in that system. A number of features of that context were emphasised in MacKenzie. They include the following. First, as in the present case, where an indictment contains multiple counts, the jury will ordinarily be directed to give separate consideration to each count. This will often be accompanied by a specific instruction that the evidence of a witness may be accepted in whole or in part. Secondly, emphasis will invariably be placed upon the onus of proof borne by the prosecution. In jurisdictions where unanimity is required, such as New South Wales, every juror must be satisfied beyond reasonable doubt of every element in the offence. In the case of sexual offences, of which there may be no objective evidence, some, or all, of the members of a jury may require some supporting evidence before they are satisfied beyond reasonable doubt on the word of a complainant. This may not be unreasonable. It does not necessarily involve a rejection of the complainant's evidence. A juror might consider it more probable than not that a complainant is telling the truth but require something additional before reaching a conclusion beyond reasonable doubt. The criminal trial procedure is designed to reinforce, in jurors, a sense of the seriousness of their task, and of the heavy burden of proof undertaken by the prosecution. A verdict of not guilty does not necessarily imply that a complainant has been disbelieved, or a want of confidence in the complainant. It may simply reflect a cautious approach to the discharge of a heavy responsibility. In addition to want of supporting evidence, other factors that might cause a jury to draw back from reaching a conclusion beyond reasonable doubt in relation to some aspects of a complainant's evidence might be that the complainant has shown some uncertainty as to matters of detail, or has been shown to have a faulty recollection of some matters, or has been shown otherwise to be more reliable about some parts of his or her evidence than about others. Thirdly, there is the consideration stated by King CJ in R v Kirkman, and referred to in later cases: it may appear to a jury, that, although a number of offences have been alleged, justice is met by convicting an accused of some only. And there may be an interaction between this consideration and the two matters earlier discussed.
It appears from the review of decisions of trial judges and intermediate appellate courts undertaken in Markuleski that some judges have taken Jones as authority for the proposition that where multiple offences are alleged involving the one complainant, then verdicts of not guilty on some counts necessarily reflect a view that the complainant was untruthful or unreliable, and that an appellate court should consider the reasonableness of guilty verdicts on the basis that the complainant is a person of damaged credibility. That view is erroneous. It overlooks the attention to factual detail in the reasoning of Jones. It also overlooks the principles stated in MacKenzie, which were not qualified in Jones, and the considerations mentioned in the preceding paragraph in these reasons. Jones is not to be understood as establishing a set of legal propositions, separate or different from the test formulated in M, which must be applied in deciding whether a conviction on one or more counts of sexual offences, when the accused was acquitted on other counts, is unreasonable, or cannot be supported, having regard to the evidence.
The test established by s 6(1) of the Criminal Appeal Act is unreasonableness, not inconsistency. In the present case, there is an obvious explanation of the differences between the verdicts on the various counts in the indictment.
