The Crown case at the Trial
3 The Crown case at the trial was that the appellant had knowingly taken part in the supply of not less than a large commercial quantity of methylamphetamine by knowingly taking part in acquisitions of quantities of the drug, totalling more than the large commercial quantity of one kilogram, by her de facto husband Brett Harrison from a man named Richard Walsh and Walsh's de facto wife Melinda Love, which were then used by Harrison in making supplies to his customers. An alternative Crown case, in the event of the Crown being unable to prove that the appellant had knowingly taken part in the supply of not less than a large commercial quantity of the drug, was that the appellant had knowingly taken part in the supply of some lesser quantity of the drug.
4 The principal Crown witness at the trial was Melinda Love, who had been granted immunity from prosecution by the Attorney-General.
5 Ms Love gave evidence of contacts between herself and Harrison and the appellant in connection with the supply of drugs. On the first occasion on which she had gone to Harrison's and the appellant's house to supply Harrison with drugs the appellant had been present. Subsequently, Ms Love had received telephone calls from the appellant, as well as from Harrison, which Ms Love said were disguised requests to be supplied with drugs. On some occasions the appellant had come to Ms Love's house and collected drugs. On some occasions when Ms Love had delivered drugs to Harrison and the appellant's house, she had given the drugs to the appellant.
6 Ms Love also gave evidence that drugs were supplied to Harrison on credit and that she had had some face to face conversations with Harrison about receiving payment, at which the appellant had usually been present. Ms Love had usually received payment for supplies of drugs from Harrison but on some occasions she had received payment from the appellant.
7 Ms Love said that on one occasion she had supplied drugs directly to a woman named Kim Rolla, who was usually a customer of Harrison. Ms Love said that she had gone to Harrison and the appellant's house and had had a conversation with both of them, in which she had asked whether it was all right, if, on this one occasion, she supplied drugs directly to Ms Rolla.
8 Ms Love gave evidence that on one occasion she had picked up a pound of amphetamine which was being supplied to Walsh but which had been delivered to Harrison and the appellant's house. Both Harrison and the appellant had been present in the house when Ms Love picked up the pound of amphetamine.
9 A number of telephone conversations to which Ms Love and the appellant or Harrison or both of them had been parties had been lawfully intercepted and recorded and recordings of the conversations were admitted into evidence. In these conversations there were no explicit references to drugs. However, Ms Love gave evidence in which she said that some of what was said in the telephone conversations contained disguised references to drugs, including the appellant saying that she was going to come to Ms Love's house to pick up drugs, that she had money with which to pay for drugs which had previously been supplied and that Harrison would be coming to Ms Love's house to pick up drugs and the appellant asking Ms Love when Ms Love would be making a delivery of drugs.
10 Fairly brief evidence was also given in the Crown case by a man named Paul Chapman and his wife Anne Chapman. When Mr Chapman had been sentenced for a number of criminal offences, he had received a discount because of the assistance he had provided to law enforcement authorities, including information about the drug dealing activities of Walsh and Ms Love. Mrs Chapman had been granted an immunity from prosecution.
11 Mr Chapman gave evidence that he had made deliveries of drugs on behalf of Richard Walsh, including deliveries to Harrison. The appellant had been present when he had made most of the deliveries to Harrison.
12 Mrs Chapman gave evidence that she had been employed as a cleaner at Walsh and Love's house, that she had become trusted by them and that she had observed drug transactions taking place at the house. Mrs Chapman said that Harrison had come to the house a number of times and when he had left the house he had been carrying a package of drugs. Mrs Chapman gave evidence that on one occasion she had gone to Harrison and the appellant's house. At the house she had seen the appellant and Ms Love sitting together at a table, with a package on the table of the kind which Ms Love used for packaging drugs.
