* **s 135:**
* ****not unfairly prejudicial because damage the case of the party or support case of opponent [**Ainsworth**].
* real risk that the evidence will be _misused by the jury_ in some unfair way" [**BD** consistent with ALRC].
* procedural considerations such as innability to XX.
* steps can be taken to limit prejudice [**Calleja**].
* incorrectly assessing the weight of the evidence [**Sing Bal**] and ambiguous requiring speculation [**GAR**].
* "waste of time" if added complexity without assisting resolution of the facts in issue and may be that already admitted [**Drumbo**].
* in criminal proceedings as part of this consideration must have regard to in criminal proceedings have to have regard to onus and standard of proof.
* **s 136:**
* may be reduced by some other action such as by directions to the jury or reasoning process to be appplied in respect of evidence.
* s 136 might properly be applied to prevent use of the opinion "to prove the existence of a fact about the existence of which the opinion was expressed".
* judge can direct that certain evidence can be used to "collaborate" other evidence [**Galvin**].
* **s 137:**
* no requirement that value be "substantially" outweighed compared to s 135.
* balancing process.
* no residual discretion - the evidence must be rejected [**GK**].
* assessment of PV must be made in conjunction with all the other evidence to be adduced in the proceeding [**IMM**] [i.e. context and not isolation], as maybe already admitted from another source = PV low.
* must "substantially" outweigh - another way of saying that the onus is on the party seeking exclusion and that exclusion will only be justified in a clear case or “there must be compelling circumstances for the exclusion” [**La Trobe Capital**].
* exercise in s 135 is weighted against exclusion and in favour of admission compared to s 137. In criminal proceedings would rely on s 137, because of lower threshold and does not leave the court with a residual discretion [**Blick**].
* **in assessing PV**:
* prior to **IMM** point of difference between **Shamouil** and **Dupas** is that the VSCA held that a trial judge could take into account the reliability of the evidence in assessing its probative value.
* must take into account the use that the party adducing the evidence seeks to make of the evidence. Must be in relation to that use notwithstanding of another potential use of it. Risk that the evidence might be used (albeit impermissibly) in that second way may bear on the assessment of danger of unfair prejudice.
* if for more than one purpose, do not look at each purpose in isolation [**Davies**].
* **example** of a situation where the power may be utilised is where the prosecution tenders gruesome photographs of the deceased in a murder trial, where a pathologist has already described the injuries and there is little forensic assistance to be derived from the photographs. Thus, may have to adjourn or edit or direct the jury.
* enquiry for the purposes of _s 55_ is _whether the evidence is capable of the effect_ described at all. but enquiry for the purposes of determining PV o is as to _the extent of that possible effect_ [**IMM**]. Neither s 55 or s 56 requires that evidence be probative to a particular degree for it to be admissible.
* must proceed on the assumption that the evidence "is accepted" (and thus is to be regarded as both credible and reliable) [**IMM**]. The credibility or reliability of evidence cannot be considered when assessing probative value, but evidence taken at its highest can still be “weak” and “unconvincing”. Does not require that the matter thereby "evidenced" must also be assumed to be accepted, as “circumstances surrounding the evidence may indicate that its highest level is not very high at all.” evidence which is “inherently incredible or fanciful or preposterous” would not appear to meet the threshold requirement of relevance.
* in **DSJ** he court may have regard to any alternative explanation to that advanced by the prosecution if it arises on the evidence. Also, see **XY** which is consistent with DSJ and inconsistent with **Sood.** **Burton** held that **Sood** was still good law [i.e. court assessing the probative value of evidence for the purposes of this provision is _required to assume that the inference(s) sought to be drawn by the prosecution will be drawn, without any availability of any competing inference_]. **IMM** at [45] suggests that determination of the probative value of circumstantial evidence does not require competing inferences to be ignored by the judge. In a **Restricted Judgement Burton** reaffirmed. - "it was no part of the trial judge's function in assessing probative value under s 137 to have regard to competing explanations for the respondent's conduct, other than that upon which the Crown relied". In **Bauer** the only sense in which competing inferences are of significance in the assessment of the probative value of evidence is in the determination of whether the evidence could rationally affect the assessment of the probability of the existence of a fact in issue.
* contamination, concoction or collusion goes only to the credibility and reliability of evidence and, therefore, is an assessment which must be left to the jury [**Bauer**], unless not rationally open for jury to accept the evidnece.
* **"danger of unfair prejuice":**
* "prejudicial effect" in s 101, "unfairly prejudicial" in s 135 and "unfair prejudice" in s 137, each conveys essentially the same idea of harm to the interests of the accused by reason of a risk that the jury will use the evidence improperly in some unfair way [**Bauer**]
* **considering unfair prejudice:**
* ****consider as a whole and not in isolation [**Aytugrul**].
* procedural considerations such as inability to XX [**Bauer**]
* danger of giving too much weight [**Dickman** and **Ngo**].
* scientific evidence because of a danger that the evidence will be misleading or confusing **Aytugrul**] and may not be cured by directions [**Wise**].
* **s 138:**
* balance of the competing public interests.
* in a criminal proceeding in which the prosecution seeks to adduce evidence that has been improperly or illegally obtained the more focussed public interests identified in **Bunning v Cross** remain apt [**Kadir**] [i.e. convicting wrongdoers vs curial approval, or even encouragement, to the unlawful conduct of those whose task it is to enforce the law].
* balancing test must be applied in respect of each item of improperly obtained evidence.
* conduct need not necessarily be wilful or committed in bad faith or as an abuse of power". It need not be "deliberate or reckless" [**Carr**].
* for the courts themselves to determine whether methods used to obtain evidence are "proper" or "improper" [**Ridgeway**].
Parker refered to definition of Oxford English Dictionary.
* **approach** as per **Robison:**
* ****identify minimum standard viewed by society from those with power [i.e. minimu standsrds of acceptable police conduct].
* contravention must not be "minor", but "quite inconsistent with" or "clearly inconsistent with".
* standard for private individuals is less clear [**Kadir**].
* failure to comply with s 132 obligation will suffice [**LGM**].
* evidence may possess high PV in a case in which other equally probative evidence is available to the prosecution [**Kadir**], however, if that evidence is exluded then PV increases.
* in criminal, the more serious the offence, the more likely that the public interest requires admission [**Dalley**].
* chain of causation must be shown between the impropriety or contravention and the obtaining of the evidence [**Cornwell**] it is a "but for" test of causation [**Restricted Judgment**]
* s 138(3) are overlapping, and that it is not wrong to look at them together and should not be considered in isolation [**Kadir**].
* for "desirability of admitting evidence" [see **Kadir**].
* the greater the PV the greater the public interest in its admission [**Camilleri**].
* Prejudice" to a defendant arising simply from the fact evidence tends to prove guilt would not in any way support exclusion of the evidence [**Camilleri**]
* "deliberate" impropriety or requires knowledge or awareness that the conduct involved is improper or unlawful [**Marijancevic**].
* where an officer is likely to be dealt with in another forum for his or her misconduct, the need to exclude evidence as a deterrent is reduced" [**Kadir**].
* in a case where action is taken urgently in order to preserve evidence from loss or destruction, it is possible that factor (h) would weigh in favour of admission, notwithstanding that the action involved deliberate impropriety or illegality [**Kadir**].
* onus is on the party seeking exclusion to demonstrate that it was unlawfully obtained If that onus is met, it is for the party seeking admission of the evidence to satisfy the court that the desirability of admitting such evidence outweighs the undesirability of admitting it, given the way in which it was obtained [**Parker**].
* see **Em** with respect to admissions and compare **Helmhout**.
* **s 139:**
* specified belief and not a suspicion of commission of offence [**Pearce**].
* must be "questioning" and both s 139(1)(b) and s 139(2)(a) require that the questioning have been "conducted by an investigating official".
* questioning need not be "in connection with the investigation of the commission or possible commission of an offence".
* aimed at formal or informal interrogation of a suspect by a police officer for the purpose of the officer obtaining information, whether or not at the time of the interrogation the suspect was formally under arrest [**Naa**].
* critical issue is whether the caution was communicated to the arrested person in a way which ensured that he or she understood the matters contained in the caution [Deng]. If that is not established, there is likely to be non-compliance with s 139(3), however, not if the caution could not reasonably have been expected to be perceived that the suspect did not understand the caution.
