12 The court was referred to a number of decided cases said to be of some relevance on the appropriate level of sentence. Particular reference may be made to R v Chan[3]. Chan was convicted of trafficking in a variety of drugs, principally LSD (a Schedule 1 drug) and various amphetamine related drugs (Schedule 2 drugs). Over a period of a few months there were four sales of LSD to an undercover agent involving 500 tabs (which exceeded the Schedule 3 quantity by 11 times). There was also a sale of amphetamine type drugs involving 500 tabs. $14,030.00 was paid for the above drugs. Another $33,300.00 was paid for powder containing over 51 grams of methyl amphetamine (pure) in nine transactions and a further 2.537 grams of amphetamine (pure). There was a further supply of an "ounce" of something that was falsely described as cocaine. Profits totalling $13,000.00 were expected from these transactions. Chan's admissions of other dealings were more extensive and explicit than those of the applicant including that he had previously been selling as much as 10 ounces a week of "speed" at a profit of $600.00 per ounce, that he currently dealt in between two and four ounces of "speed" weekly and that in relation to LSD he was used to ordering 50 tabs at a time. It was established that Chan was "a significant link in the chain of drug distribution before he met the agent. It was also known that the respondent trafficked with others, although not to the same extent, while supplying the agent[4]". Chan was not a drug user, and engaged in these activities solely for personal gain. There was no suggestion of remorse. However he was given due benefit for his plea of guilty. On the Attorney-General's appeal Chan was sentenced to seven years imprisonment for trafficking. Account must be taken however of the court's observation that a sentence of 11 years imprisonment would have been appropriate but for 11 months spent in pre-sentence custody and but for the plea of guilty. It would seem that after allowance for the pre-sentence custody the sentence in Chan's case was seen as one of prima facie nine years, reduced to seven years by reason of the plea of guilty. When the circumstance of Chan's pre-sentence custody is taken into account, it can be seen as roughly equivalent to a sentence of nine years.
