40Sentence Ground 1 suffers from the same deficiencies as Conviction Ground 1, upon which it is based. A contested hearing proceeded before Patten AJ to permit findings of fact to be made on sentence. The Applicant was represented by most experienced senior counsel at that hearing.
41The concept of joint criminal enterprise was only pertinent on sentence to the extent that the Crown asserted that the Applicant and the Applicant's father were motivated by financial gain in killing the victim. The Applicant denied this and asserted that the killing of the victim resulted from the past mental and physical abuse of the Applicant, including serious sexual assault, and the Applicant's lingering hatred of her grandfather which prompted the killing. Patten AJ was alive to this controversy at the sentencing hearing.
42Having outlined the evidence bearing on the Applicant's motive, his Honour expressed the following conclusion (ROS14):
"Having heard and seen the offender give evidence on several occasions I regard him as a man of no or very little credibility. I do not believe his claims that his grandfather either sexually assaulted him or was physically violent except to the extent of mild pushes or shoves. I accept, however, that there were occasions when his grandfather probably verbally abused him and this may have upset him and given rise to feelings of anger.
Although it seems improbable I cannot exclude the possibility that there is a reasonable hypothesis that feelings of ill will towards his grandfather persisted until 29 April 2005 and motivated the murder. It follows that I am not satisfied beyond reasonable doubt that the murder was entirely motivated by the prospect of financial gain."
43The Applicant's Sentence Ground 2 complains with respect to this finding of fact made by Patten AJ. This Court is a court of error. The jurisdiction of the Court to interfere with a factual finding on sentence is exercisable only where the Applicant demonstrates an error of principle, or some other mistake of fact or law or that the finding was not open: Aoun v R [2011] NSWCCA 284 at [3]-[9], [33]-[35].
44The sentencing Judge did not make a finding adverse to the Applicant as sought by the Crown with respect to motive. Nor, however, did the sentencing Judge make a finding in the favourable terms sought by senior counsel for the Applicant. In reaching the conclusions which he did, Patten AJ had regard to the totality of the evidence, including the oral evidence of the Applicant, which his Honour approached with very considerable reservations.
45It is noteworthy that Kirby J, when later sentencing the Applicant's father, made the following findings concerning the Applicant (R v Clark (No. 3) at [12]-[13]):
"[12] Ben Clark said that when he shot Dick Clark he was acting alone and out of fear. He explained that there had been a number of incidents five years earlier when he was working for Dick Clark. They took place during two weeks when he was at Dick Clark's workshop at Granville in late 2000, or early 2001. His grandfather had repeatedly assaulted him sexually. Eventually, he had anally raped him. He was, at the time, some months short of 17 years old. The assaults were perpetrated in various locations throughout the workshop. The rape occurred in a small and cluttered room towards the rear of the workshop. His wrists had been bound to a shelf whilst he was raped. The jury was instructed that if they believed there was a reasonable possibility that Ben was sexually assaulted by Dick Clark, such that he had his own reasons for disliking his grandfather and may possibly have acted alone, they must acquit Michael Clark. The jury, by their verdict, clearly rejected Ben Clark's evidence, which was unsurprising. His evidence, in its presentation and detail, was completely implausible.
[13] What, then, was the motive of Ben Clark? There was some evidence of ill-feeling between Dick Clark and Ben, arising out of the short time that Ben had spent working in his grandfather's workshop and showroom in 2000 or 2001. Patten AJ, when sentencing Ben Clark, accepted that Dick Clark probably abused Ben verbally because he regarded him as lazy. He may even have mildly pushed him or shoved him to get him moving. Patten AJ could not exclude the possibility that some ill-feeling persisted, and provided part of Ben Clark's motivation. I share that view."
46Having considered the submissions advanced by the Applicant to this Court, it has not been demonstrated that the factual findings made by Patten AJ were not reasonably open to him. Sentence Ground 2 ought be rejected.
47With respect to Sentence Ground 3, I am entirely unpersuaded that any error has been demonstrated concerning the listening device evidence, let alone an error which impacted adversely to the Applicant on sentence. I have considered this topic above at [34]-[36]. I would reject that ground of appeal.
48In support of the sentence appeal, the Applicant sought to rely upon her transgender status within the prison system since September 2011. Some documentary evidence was adduced concerning management of transgender prisoners in the custodial setting. The Applicant acknowledged that this issue could only be relevant if the Court found error and was otherwise proceeding to resentence the Applicant (T8-9, 27 April 2012).
49As no error has been demonstrated, this Court is not proceeding to resentence the Applicant. As the transgender status issue arose only in September 2011, long after the Applicant was sentenced, it is not a matter which can appropriately be ventilated on appeal to this Court: Norrie v R [2008] NSWCCA 185 at [13]-[24]. To the extent that this Court has accepted that post-sentence events may be relied upon in exceptional circumstances, I do not consider that the present case may be so classified: Springer v R [2007] NSWCCA 289; 177 A Crim R 13 at 15-16 [3], 20-22 [25]-[32].
50As the Applicant is unrepresented, I have considered the quantum of the sentence imposed upon her in the circumstances of this offence. I detect no error on the part of the sentencing Judge in the determination of sentence. His Honour took into account the Applicant's plea of guilty, the finding as to motive (which was not unfavourable to the Applicant), her subjective circumstances, and made a finding of special circumstances leading to the imposition of a non-parole period of 14 years with a balance of term of six years. Having regard to the Applicant's crime, no error has been demonstrated in the imposition of this sentence.
51I observe that Kirby J later sentenced the Applicant's father to a total term of 30 years' imprisonment with a non-parole period of 24 years, after considering submissions relating to proportionality of sentences for the Applicant and the Applicant's father: R v Clark (No. 3) at [38]-[39].
52In my view, the grounds of appeal against sentence are sufficiently unmeritorious that leave to appeal against sentence ought be refused.
53I propose the following orders:
(a) leave to appeal against conviction refused;
(b) leave to appeal against sentence refused.
54GARLING J: I agree with Johnson J.
