4 The amount of the heroin involved was 2,103.5 grams. On analysis, the substance was found to contain 893 grams of pure heroin. The sale initiated was for six blocks of heroin, each weighing 12.5 ounces at $51,000 per block. It was estimated the heroin had a street value of $2.1 million, but the sentencing judge accepted that as a vague estimate.
5 In the appeal of Pham, Wood CJ at CL, summarised the facts as follows:
"3. The offences were detected during a targeted NCA operation, and involved a somewhat sophisticated and well organised criminal venture on the part of those involved. It is common ground that the offender occupying the highest rung in the distribution chain was a person Cuong, known by the honorific 'Uncle'. It was he who initially held the drugs, and it was from him that the others took instructions. However, both the applicant and a co-offender, Nguyen, were significantly involved in the operation, being persons described by his Honour as 'secondary principals'. This was a term of somewhat uncertain meaning and of dubious value. However, it can be taken to mean that these two offenders were the persons entrusted with authority to arrange the sale of drugs and to effect their delivery once a sale had been negotiated.
