THE OFFENDER'S SUBJECTIVE CASE
32The offender is 33 years of age. She has two children from a previous relationship, who are now aged 12 and 11 respectively. The offender's eldest daughter has what have been described as "multiple neurological challenges" and is currently under the care of a paediatrician. Her youngest daughter suffers a learning disability.
33According to the statements made by the offender to the author of the pre-sentence report, Comber introduced her to illicit drugs in 2007/2008, as a consequence of which she became addicted to amphetamines and cannabis. According to information provided by the offender and which is recorded in the pre-sentence report, she abstained from drug taking some three years ago. That was confirmed by her mother who gave evidence before me on sentence, and I am satisfied that this is the case.
34The offence was not part of any planned or organised criminal activity. That is a mitigating factor pursuant to s. 21A(3)(b) of the Crimes (Sentencing Procedure) Act 1999 ("the Sentencing Act").
35The offender has no record of previous convictions. That is a mitigating factor pursuant to s. 21A(3)(e). However, counsel for the offender went further, and submitted that the offender was a person of good character within the meaning of s. 21A(3)(f) of the Sentencing Act. Evidence of an absence of previous convictions, combined with other evidence, is capable of amounting to material that might support a finding that the offender was otherwise a person of good character. That is a matter which must be established on the balance of probabilities (see Aoun v R [2007] NSWCCA 292 per Hodgson JA (with whom Hislop and Latham JJ agreed) at [23]-[24]). In the present case, I have heard sworn evidence from the offender's mother, which was not the subject of any real challenge by the Crown. Although that evidence was limited, I am satisfied on the balance of probabilities that the offender was a person of good character within the meaning of s. 21A(3)(f) of the Sentencing Act.
36Counsel submitted that I should find that the offender has good prospects of rehabilitation and is unlikely to re-offend. The evidence which might support that finding is limited to say the least. The author of the pre-sentence report concluded by expressing the view that the offender was suitable for a low to medium level of intervention which, he said, was "commensurate with the assessed risk". I assume that this refers to the risk of re-offending, however the nature and extent of the assessed risk was not otherwise identified.
37In these circumstances I am not able to reach any conclusion regarding the risk of re-offending, or the offender's prospects of rehabilitation.
38Finally, at least in terms of the factors set out in s. 21A(3), I have had regard to the fact that the offender pleaded guilty, although it must be noted that the plea came at a late stage, the offender having been committed for trial in late 2011 on the charge of being an accessory after the fact to the murder of the deceased. I was also asked to have regard to the fact that the offence is one which was capable of being dealt with summarily by a Magistrate (as to which see generally R v Palmer [2005] NSWCCA 349 at [15] per Hall J (Grove J and Smart AJ agreeing). In view of the conclusion I have reached, I need not give any further consideration to this issue.
39Leaving aside the statutory mitigating factors, the submissions on behalf of the offender concentrated upon two particular matters.
40The first was the fact that the offender is the sole carer of two of her daughters, both of whom have the difficulties to which I previously referred. In this regard the offender's mother gave evidence, which I accept, that she is required to assist the offender from time to time in the care of her children. However as a general principle, hardship to the dependants of an offender is an unavoidable consequence of a custodial sentence and is not a mitigating consideration unless a conclusion can be reached that such hardship is properly regarded as exceptional (see R v Edwards (1996) 90 A Crim R 510). Counsel for the offender ultimately accepted that the circumstances of the present case did not fall into the exceptional category.
41The second matter, upon which significant emphasis was placed, was what was described in the written submissions as the offender's "mental state". In this respect, the following was stated in the pre-sentence report:
"Ms Weston's Doctor confirmed that she was diagnosed with a learning disability at age 16 years and is intellectually impaired with a low IQ. He advised that she had an equivalent mental age of 11 years when she was 16 years old. The Doctor advised that as a child she exhibited behavioural problems due to her poor cognitions and lack of coping skills. Despite these difficulties the Doctor confirmed that the offender knows the difference between right and wrong. In addition, he confirmed that Ms Weston was prescribed anti-depressants in January 2010; however the Doctor advised that the offender ceased taking the medication some months later without prior consultation".
42In addition, counsel for the offender tendered a report of Dr Lynette Arnoldus-Lewis, psychologist. Ms Arnoldus-Lewis spoke with the offender on two occasions, each for a period of one hour. She administered no psychometric testing to assist her in making assessment of the offender's psychological state, IQ, or functional incapacities, stating that she had adopted "a qualitative approach" which was said to be based upon (inter alia) "interviews and data generated from sessions". I assume that amongst the interviews which were used in this way where the two interviews with the offender.
43I have read the report of Ms Arnoldus-Lewis carefully. It has provided me with little or no assistance in assessing the offender's subjective circumstances generally, or determining her mental state in particular.
44It is evident that Ms Arnoldus-Lewis had difficulty in obtaining any cogent information from the offender. Indeed, she specifically commented upon the fact that it was "difficult or near impossible to facilitate a consistent meaningful response from (the offender), no matter what topic". As I have observed, Ms Arnoldus-Lewis chose to approach her assessment by relying upon (inter alia) the content of her interview with the offender. In circumstances where such difficulties were experienced in obtaining any meaningful response from the offender, it must be said that the approach which was adopted to the preparation of the report, to the extent that it relied partly upon the content of an interview with the offender, may not have been the best one.
45Further, and bearing in mind the purpose for which it was tendered, the report is completely bereft of any diagnosis as to the offender's mental state. The closest it reaches in that regard is the passage which records the following:
"....I conferred with her life-long (since birth) GP, Dr Aldo Castanga, on 18 July 2012. Dr Castanga confirmed that Ms Weston was intellectually or developmentally impaired with a low IQ which was more than likely congenital, as there was a family history of varying degrees of intellectual impairment or developmental delay, including her mother, and two young daughters."
46It is apparent that the offender's General Practitioner, to whom both Ms Arnoldus-Lewis and the author of the pre-sentence report spoke, has treated the offender for a period in excess of 30 years. In addition, the pre-sentence report records the fact that the author spoke to a person described as the offender's psychologist (which I construe to be a reference to a treating psychologist, and someone other than Ms Arnoldus-Lewis).
47I am at a loss to understand why I have not been provided with a report from one or the other (or both) of these practitioners. Instead, I have been provided with a report produced as a result of two short consultations conducted for medico legal purposes which reaches no definitive conclusion, arrives at no identifiable diagnosis, and contains an observation that the offender "does not have the mental, social or moral capacity to accept responsibility for her involvement in the aforementioned criminal act", an observation which counsel conceded was somewhat inconsistent with the offender's plea of guilty.
48In circumstances where there has been considerable focus in the submissions upon the offender's "mental state", and the extent to which that condition should be taken into account on sentence, I regard the state of the evidence as most unsatisfactory.
49Counsel described the offender's relevant mental state as being an "intellectual or developmental disability with a low IQ and a reading age of 11 years when 16 years". He conceded that according to information obtained by the author of the pre-sentence report from the offender's General Practitioner, the offender was a person who "does understand the difference between right and wrong". Nevertheless, he submitted that in all of the circumstances, the offender's mental state was such that she was not an appropriate vehicle for general deterrence.
50There is no doubt that the presence of a substantial and chronic mental illness is relevant to a determination of whether the case is one which calls for a particular measure of general or specific deterrence (see R v Sharrouf [2009] NSWSC 1002 per Whealy J at [61] and the authorities cited therein).
51However, the difficulty in the present case is that the evidence falls substantially short of establishing that the offender has any significant mental disorder or abnormality. The pre-sentence report makes reference, on the basis of information provided by the offender's General Practitioner, to an "intellectual impairment". It also refers to the fact that the offender was prescribed anti-depressant medication in 2010, but ceased taking that medication shortly after it was prescribed for her. The latter reference may tend to indicate that the offender was diagnosed with depression at some point, but the present position is simply not known. This issue, along with many others, would seemingly have been capable of resolution had the appropriate evidence been placed before the court.
52I am satisfied that the offender suffers from some form of intellectual impairment. The evidence does not enable me to determine the nature of that impairment, nor its extent. Whilst I have taken it into account as part of the offender's subjective circumstances, I am not satisfied that the offender's mental state is such that normal principles of general deterrence should not apply.
