16 Furthermore it is submitted that when regard is had to the only other cases to come before the Court of Appeal, the sentence imposed on count 1 can be seen to be manifestly excessive. Indeed it is submitted that this case involves the harshest sentence yet imposed for this offence. In this regard it should be observed that the offence of trafficking in a large commercial quantity came into operation on 1 January 2002.[1] The first case considered by the Court of Appeal would appear to be R v S[2]. In that case 'S' had been sentenced to a term of imprisonment of six years with a non-parole period of three years and nine months for trafficking in a large commercial quantity of cannabis. 'S' was the caretaker of 140 fully grown plants which yielded 1.5 tonnes in their green state and which, when dried, would have yielded at least 168.7 kilograms. A significant factor in the case of 'S' was the fact that a substantial reduction of his sentence was made by reason of his willingness to provide critical assistance to the prosecuting authorities. Furthermore, 'S' was not the owner of the crop, nor would he have benefited financially from its sale. His appeal on the grounds of manifest excess was dismissed. In R v Sibic and Sibic[3] two brothers were sentenced on a count of trafficking in a large commercial quantity of cannabis. One of them was sentenced to nine years' imprisonment with a non-parole period of five years and eight months and the other was sentenced to nine years' imprisonment with a non-parole period of six years. At the time of arrest there were 2,100 plants growing. The trafficking had been conducted over a period of two years and four months. In addition to the crop, bags and other containers containing more than 204 kilograms of cannabis were found in a property occupied by the appellants. In the case of one brother, who suffered from brain damage and bipolar disorder and who at the time of sentence was wheelchair bound by reason of spinal lesions, the court reduced his sentence to a term of imprisonment of eight years with a non-parole period of four years. The other brother was re-sentenced to a head sentence of nine years' imprisonment with a non-parole period of five years. In R v Duncan[4] the applicant had been convicted on one count of trafficking in a large commercial quantity of MDMA. On that count he was sentenced to a term of imprisonment of eight years with a fine of $3,500. By reason of conviction on other counts of trafficking and possession, his total effective sentence was eight years and ten months with a minimum term of four years and five months before being eligible for parole. An argument that the sentence imposed was manifestly excessive was rejected. In R v D'Aloia[5] the applicant, who operated at a higher level in the distribution chain than his co-offender Duncan, was sentenced to nine years' imprisonment on the count of trafficking in a large commercial quantity of MDMA. This sentence was described by Nettle JA, with whom Vincent JA and King AJA agreed as being 'well within the range'.[6] Although there are distinctly different factual differences between the cases referred to and the case now before us it does appear that the contention that the sentence imposed in the present case is higher than any other case dealt with previously by the Court of Appeal is correct.
