Chami received 15 years for an offence of aggravated sexual intercourse without consent and 7 years for detention for advantage. However, the detention of Chami was worse than that effected by H, because Chami made threats with a weapon and made it possible for [Bilal Skaf] and another man to carry out a series of sexual assaults against Miss C in his car as he was driving. I consider that the sentences for these offences, committed by [the applicant and his brother], should be the same as for similar offences committed by [the applicant's brother] and H against Miss A and Miss B, ie 11 years and 3 months for aggravated sexual assault and 3 years and 9 months for detention for advantage.
12 The above remarks make it clear that his Honour approached the sentencing of the applicant for the offences committed by him on 30 August principally by reference to the detention offences and aggravated sexual assault offences committed by H and the applicant's brother on 10 August, having regard to the fact that they had pleaded guilty. It is significant, however, that his Honour also refers to the sentences imposed upon Chami for offences committed on 30 August, which were similar to the offences committed by the applicant. Chami was convicted after trial of one count of penile vaginal intercourse which occurred in the back seat of the red car at the industrial estate at Chullora and one count under s 90A, relating to the detention of Ms C in that car, including the production of what Ms C thought was a weapon in the course of the journey from Bankstown Trotting Club to Chullora. As his Honour noted, the objective gravity of the detention offence committed by Chami was greater than the objective gravity of the detention of Ms A and Ms B in Northcote Park for that reason.
13 It is appropriate then to turn to an examination of the offences committed by H and by the applicant's brother on 10 August. The facts in relation to the detention and sexual assault of Ms A and Ms B on 10 August at Northcote Park in Greenacre are set out at length in our judgement on the application for leave to appeal by H (H [2005] NSWCCA 282, par 12) Without repeating those facts in full, it is sufficient to note that H was sentenced in relation to two counts of detain for advantage, one each in respect of Ms A and Ms B, based upon the detention of each of those complainants within the park, over a period of some hours. In respect of each of those offences, H received a fixed term of three years and nine months' imprisonment. H was also sentenced in respect of three counts of aggravated sexual assault, only one of which was as a principal in the first degree (count 8). The Judge was asked to take into account two further offences on a Form 1 when sentencing H in respect of this offence. Those offences were two counts of common assault, one relating to Ms A and the other to Ms B. They related to the presence of H whilst each of the complainants was tackled to the ground by a co-offender. The sexual assault offence was constituted by H approaching Ms A and threatening to bash her if she did not give him a "head job". H threatened Ms A with a clenched fist, held the back of her head and grabbed her breasts. He forced her mouth onto his penis until he ejaculated on Ms A. H then walked away, saying "thanks for nothing you cheap slut". The offence was committed after Ms A had been forced to commit fellatio on three of the co-offenders and before she was forced to commit fellatio upon another co-offender. H received a sentence of eleven years and three months' imprisonment, with a non parole period of six years.
14 The applicant's brother was also sentenced for two counts of detention relating to the detention of Ms A and Ms B at Northcote Park. In respect of each offence, he received a term of three years and nine months' imprisonment. The applicant's brother was also sentenced for three counts of aggravated sexual intercourse without consent, two in respect of Ms A and one in respect of Ms B. However, only one of those counts was as a principal in the first degree. That was an act of forced fellatio committed on Ms A which followed the act of forced fellatio committed upon that complainant by H and another offender. When sentencing the applicant's brother on the offence committed as a principal, three further offences were taken into account on a Form 1. They were two charges of common assault and one charge of aggravated indecent assault. The aggravated indecent assault consisted of grabbing Ms A around the breasts while they were seated in the van between Chatswood and Greenacre. One common assault was committed as a principal in the second degree and the other common assault consisted of Ms A being tackled by the applicant's brother. The applicant's brother received a sentence of eleven years and three months, with a non parole period of seven years on this offence.
15 In so far as the applicant relies upon comparisons between the objective gravity of the offences committed by the other offenders on 30 August, in particular those offences committed on Ms C at other locations, including Bankstown Trotting Club and Chullora, and the asserted lesser objective gravity of the offences committed on 30 August by the applicant, we regard those comparisons of dubious value for the purposes of this appeal. Simply put, that was not the basis upon which the Judge approached the sentencing of the applicant.
16 We have observed in the course of our reasons on the appeals by the applicant's co-offenders, that his Honour adopted a starting point of fifteen years' imprisonment (before the application of the discount for a plea of guilty) for offences of aggravated sexual assault, without differentiating between penile-vaginal intercourse and fellatio. There is nothing inherently wrong with that approach: R v Andrews [2001] NSWCCA 428. What was required was a determination in each case as to where the various acts of sexual intercourse lay in the spectrum of offences falling within the definition of sexual intercourse: Ibbs v the Queen (1987) 163 CLR 447. The circumstances of an act of fellatio may place it in a position on that spectrum consistent with an act of penile-vaginal intercourse. For example, where the complainant's head is forced and held onto the offender's penis to the point of ejaculation into the complainant's mouth, while threats and insults are uttered, in the company of a number of other offenders who are waiting their turn, little may objectively differentiate such an offence from an act of penile-vaginal intercourse, absent overt threats where the offender wears a condom. We are not persuaded, for that reason, that his Honour necessarily fell into error by having regard to the offences committed by the applicant's brother and H on 10 August 2000, when determining the sentence to be imposed on the applicant for an offence committed on 30 August for an aggravated sexual assault offence of a different nature.
17 Nor are we persuaded that his Honour erred in referring to the offences committed by H and the applicant's brother on 10 August, in so far as those offences were committed against complainants other than Ms C. His Honour adopted the correct approach in fixing a sentence for individual offences which reflected the objective gravity of the conduct involved in those offences and thereafter reflected the totality of the criminality represented by sexual assaults on separate complainants by the partial accumulation of those sentences.
18 A further alleged source of disparity arises from the sentence imposed on the applicant's brother for the aggravated sexual assault on 10 August, committed as a principal in the first degree, after taking into account three further offences, pursuant to s 33 of the Crimes (Sentencing Procedure) Act 1999 (the Sentencing Procedure Act). It was submitted that the applicant must entertain a legitimate sense of grievance, in that he received an identical sentence for an offence unaffected by the requirements of s 33 of the Sentencing Procedure Act. As we have noted elsewhere, the reflection of further offences in a sentence for a primary offence lies in the weight to be accorded to personal deterrence and retribution: Attorney General's application under s 37 of the Crimes (Sentencing Procedure) Act 1999 (No. 1 of 2002) [2002] NSW CCA 518. It has not been doubted since R v Barton (2001) NSW CCA 63 that the application of s 33 of the Sentencing Procedure Act generally results in a longer sentence or greater penalty than would have been the case if a judge was sentencing only for the primary offence. The same potential disparity arises from a comparison with the sentence imposed upon H in respect of count 8 of the indictment presented against him, to which he pleaded guilty. The sentence imposed upon him was also imposed after taking into account two further offences on a Form 1, albeit they were not as objectively serious as the Form 1 offences committed by the applicant's brother.
19 The Crown's submission is that no disparity arises because his Honour took the offences on the Form 1 into consideration in respect of the applicant's brother and H, but did not see the need to increase the sentence for the primary offence in each case, beyond that which was considered appropriate to the criminality of the primary offence standing alone. Such an approach is within the exercise of the sentencing discretion where the total period of imprisonment "best meets the situation": Attorney General's application under s 37.
20 In order to resolve this issue, it is instructive to consider the sentence imposed upon Chami for the aggravated sexual assault offence committed against Ms C on 30 August. Given that a sentence of fifteen years' imprisonment was imposed following conviction after trial where no question of Form 1 offences arose, it is apparent that the Crown's submission as to the approach adopted by his Honour when sentencing H and the applicant's brother must be accepted. Accordingly, we are not persuaded that the applicant has a legitimate sense of grievance which calls for the intervention of this Court.
