Sections 135 and 137
24 Section 135 provides:
" 135 General discretion to exclude evidence
The court may refuse to admit evidence if its probative value is substantially outweighed by the danger that the evidence might:
(a) be unfairly prejudicial to a party, or
(b) be misleading or confusing, or
(c) cause or result in undue waste of time."
25 Section 137 provides:
" 137 Exclusion of prejudicial evidence in criminal proceedings
In a criminal proceeding, the court must refuse to admit evidence adduced by the prosecutor if its probative value is outweighed by the danger of unfair prejudice to the defendant."
26 Both sections require the Court to consider the probative value of the evidence which the Crown now seeks to tender.
27 Part 1 of the Dictionary to the Act defines "probative value" in these terms:
"Probative value of evidence means the extent to which the evidence could rationally affect the assessment of the probability of the existence of a fact in issue."
28 The evidence give by Shannon Styman at the earlier trial is evidence that goes directly to the involvement of the accused in the events that occurred at the home of the deceased on the occasion that her home was invaded, the robbery occurred and the deceased was left bound and gagged. In short, Shannon Styman's evidence previously given was to the effect that the three men went to the house together after the accused told him of a previous unsuccessful attempt that they had made to break into the home of the deceased. According to Shannon Styman, when the three men went to the house, entry was gained through the back door when the accused Peter Taber used a sawn-down key to open that door. His evidence was that Peter Taber told him his part would be to restrain the deceased whilst Peter Taber and Ian Styman found the money in the house. His evidence was that the three men wore gloves when they entered the house, that Peter Taber took some "ladies undies" off the clothesline and that these were used when gagging the deceased. He gave evidence describing how the three men participated in gagging and binding the deceased and he said that whilst he held her down on the bed, the accused now before the Court made a search. He gave evidence that one of the cable ties on the deceased's hand was too tight and he called Ian Styman back into the bedroom and one of the cable ties was cut off, being replaced by duct tape. He said he saw Ian Styman find a bag, a black purse and a brown paper bag that contained money. The money having been discovered, the men left the house leaving the deceased bound and gagged on the bed in her bedroom.
29 I have briefly summarised the previous evidence Shannon Styman gave on issues central to the Crown case against the present accused.
30 There can be no question as to the relevance of the evidence now sought to be introduced. Plainly, that evidence, if believed, could rationally affect the assessment of the probability of the existence of the relevant facts the evidence addresses.
31 Ultimately, it is a question of fact for the jury to determine what evidence it accepts and what evidence it rejects. In R v Carusi (1997) 92 A Crim R 52 Hunt CJ at CL, with whom the other members of the court agreed, expressed the opinion that it was not for the judge in assessing the probative value of evidence to determine whether the jury should or should not accept it. His Honour said in Carusi (at pp 65-66):
"It was for the jury, and not for the trial judge, to determine the factual issues at the trial. Applying the ordinary tests, there was clearly a case to go to the jury based upon the evidence in chief of Mrs McHugh which (if that evidence were accepted) was a strong one, and it was for the jury to determine which parts of her evidence they accepted and which parts they rejected (Rothery (1925) 25 SR (NSW) 451 at 461; Jayasena [1970] AC 618 at 624; Haw Tua Tau v Public Prosecutor [1982] AC 136 at 150-151; Towers (1984) 14 A Crim R 12 at 15; R (at 81; 410-411); Doney (at 214-215; 162)). The power of the trial judge to exclude evidence in accordance with the Christie discretion does not permit the judge, in assessing what its probative value is, to determine whether the jury should or should not accept the evidence of the witness upon which the Crown case depends. The trial judge can only exclude the evidence of such a witness where, taken at its highest, its probative value is outweighed by its prejudicial effect; whereas this Court may use its supervisory powers to set aside a verdict where, the issue having been left to the jury, this Court is satisfied - on the whole of the evidence - that the jury ought nevertheless have had a reasonable doubt (M (1994) 181 CLR 487 at 492-495; 76 A Crim R 213; McKnoulty (1995) 77 A Crim R 333 at 338-339)."
32 It is to be observed that in Carusi the court was concerned with the common law Christie discretion whereby the trial judge could exclude evidence where its prejudice to the accused outweighed its probative value.
33 In Li v The Queen (2003) 139 A Crim R 281 the Court of Criminal Appeal acknowledged the role of the jury in assessing evidence when considering whether error had occurred in allowing evidence notwithstanding s 137 of the Evidence Act. A number of factors were advanced in that case, said to affect the reliability of opinion evidence from an "ad hoc" expert. Those matters were regarded by the court as matters for the jury (see p 288 [45]-[46]; see also p 292 [77]-[78] where the like approach was taken concerning the evidence of another witness).
34 Conflicting views have been expressed by McHugh J in Papakosmas v The Queen (1999) 196 CLR 297 and by Gaudron J in Adam v The Queen (2001) 207 CLR 96 as to the appropriate approach in the consideration of "probative value" for the purposes of ss 135 and 137.
35 In Papakosmas McHugh J said (at 323 [86]):
"Probative value is defined in the Dictionary of the Act as being 'the extent to which the evidence could rationally affect the assessment of the probability of the existence of a fact in issue'. That assessment, of course, would necessarily involve considerations of reliability. 'Probative value' is an important consideration in the exercise of the powers conferred by ss 135 and 137. An assessment of probative value, however, must always depend on the circumstances of the particular case at hand."
36 In Adam v The Queen, Gaudron J said (at p 115 [60]):
"The omission from the dictionary definition of 'probative value' of the assumption that the evidence will be accepted is, in my opinion, of no significance. As a practical matter, evidence can rationally affect the assessment of the probability of a fact in issue only if it is accepted. Accordingly, the assumption that it will be accepted must be read into the dictionary definition."
37 Evidence could rationally affect the assessment of the probability of the existence of a fact in issue only if it was accepted, and whether or not evidence is accepted is essentially a jury issue. However, it seems to me that there may be occasions in which a judge, when required to consider the application of s 137, may regard evidence sought to be introduced as incredible and for this reason such as ought not to be introduced: see as to this R v Cook [2004] NSWCCA 52.
38 On his own version of events, Shannon Styman was an accomplice and the jury would have to be given the customary warning that his evidence may be unreliable in the event that it is introduced. There is the further feature that he refused to give evidence at this trial and the jury had the opportunity of seeing him in Court in the course of this trial. They had the opportunity of observing him and his apparent contempt of Court whilst he was within the Court. That behaviour could be expected to have had an adverse effect on the jury's assessment of Shannon Styman.
39 On the other hand, there is circumstantial evidence which lends support to Shannon Styman's version of events.
40 There is the evidence of Mr Peake that he journeyed with the accused whilst they undertook what the jury could conclude was a recognizance exercise concerning 23 Spies Avenue. There was his further evidence that he saw them using ties of the type used to tie up the deceased when Mr Peake joined them in the room where, according to him, the accused were so engaged at the home of Mr Taber Snr.
41 Then there is the evidence concerning the financial position of each of the accused prior to the deceased being robbed. There is a significant body of evidence from which the jury could conclude that both men were extremely short of ready funds prior to the robbery. This is to be contrasted with the position after the robbery and there is evidence that each accused had significant resources of ready cash on 7 January 2001. There is evidence upon which the jury can conclude that the robbery took place early on that morning and it was later on that morning that both accused travelled to Sydney and used cash, including old notes no longer in circulation, to purchase motor vehicles. There is evidence from a number of sources that the deceased had a supply of old $100 notes.
42 There is evidence also that Leonie Ravell, with whom the accused Peter Taber was living, went on a shopping spree on and after 7 January 2001, buying white goods for the house and personal items for herself. She was observed to have a large number of banknotes in her wallet, such as prevented it from closing.
43 There is the evidence then of the discussion at 211 Old Southern Road about the lack of available money to finance the trip that had been planned to visit Queensland, and the discussion about seeking to borrow money from the deceased that was followed by the further discussion of which Donyelle Turner gave evidence. According to her, there was discussion that involved consideration of killing the deceased (T 291), although in cross examination Ms Turner said she did not take it seriously when Leonie had said, "We can always kill her."
44 There is the evidence that when the search warrant was executed at 211 Old Southern Road on 24 January 2001 black ties not dissimilar from those used to tie up the deceased were found as well as grey tape similar to that used in restraining the deceased. It is part of the Crown case that balls of scrunched up tape were found in the back of the accused Peter Taber's utility and it is the Crown case that blood was found on portion of this tape which matched the DNA profile of the deceased.
45 As against the accused Ian Styman, there is evidence that, according to his brother, Ian Styman approached him to inquire whether there was any way that John Styman, by reason of his volunteer position with the police force, could tamper with the DNA evidence if it came back positive. There is evidence from which the jury could conclude that it was Ian Styman that made the 000 call on the morning of 7 January 2001.
46 Further, the jury may well conclude that there was more than one offender involved in the commission of this crime. The way in which the deceased was bound and gagged is indicative of this. The accused were very close friends, and the evidence also indicates that Shannon Styman went where his uncle went. According to Leonie Ravell, both Stymans attended 211 Old Southern Road on the evening of 6 January 2003. She retired early and was asleep by about 8.30 pm. When she woke up it was obvious Peter Taber had not slept in their bed. He woke her early and they then set off with Ian and Shannon Styman to buy vehicles in Sydney.
47 Mr Peake's credibility is challenged and it may well be, of course, that there will be challenge to many of the links of the chain of circumstantial evidence as against each accused, but it seems to me the jury could regard circumstantial evidence which it can properly accept here as consistent with the evidence of Shannon Styman now sought to be introduced. The circumstantial evidence does not go to establishing that Shannon Styman's account of events was incorrect. Rather, it seems to me, the circumstantial evidence is substantially consistent with his version as to what occurred, and this is to be brought into account in considering the reliability of his version.
48 As I see it, the evidence sought to be introduced here could rationally affect the assessment of the probability of the existence of those relevant facts which Shannon Styman's testimony addresses. Hence, I am required to undertake the weighing process as expressed in Regina v Blick (2000) 101 A Crim R 326 at 332-333 [19]-[20]. There, Sheller JA said:
"[19] When an application is made by a defendant pursuant to s 137 to exclude evidence, the first thing the judge must undertake is the balancing process of its probative value against the danger of unfair prejudice to the defendant. It is probably correct to say that the product of that process is a judgment of the sort which, in terms of appellate review, is analogous to the exercise of a judicial discretion: see the cases referred to by Priestley JA in Moran v McMahon at 716 and following, particularly Lee Transport Co Limited v Watson (1940) 64 CLR 1 at 13 and Miller v Jennings (1954) 92 CLR 190 at 197. In the second of those cases, Dixon CJ and Kitto J, in an appeal against damages awarded by the trial judge, said of the sum awarded that it was 'reached after a very full and careful examination of the facts of the case and it represents an informed judgment upon a matter which must largely be one of opinion and must be governed to a not inconsiderable degree by an estimate formed of the witnesses and in particular the appellant'. Translated to the task set by s 137, a trial judge's estimate of how the probative value should be weighed against the danger of unfair prejudice will be one of opinion based on a variety of circumstances, the evidence, the particulars of the case and the judge's own trial experience. In that sense, the result can be described as analogous to a discretionary judgment: see Heydon, A Guide to the Evidence Acts (2nd ed, 1997), par 3.725.
[20] Even so, and with due respect, there seems to me to be a risk of error if a judge proceeds on the basis that he or she is being asked to exercise a discretion about whether or not otherwise admissible evidence should be rejected because of unfair prejudice to the defendant. The correct approach is to perform the weighing exercise mandated. If the probative value of the evidence adduced by the prosecutor is outweighed by the danger of unfair prejudice to the defendant, there is no residual discretion. The evidence must be rejected."
