39 Detective Sergeant Colin Stanbury was the last witness for the prosecution. It was his role to monitor the intercepted telephone conversations. Following the completion of his testimony and prior to counsel's addresses, Mr Traczyk revisited his objection to evidence of the four telephone conversations. He contended that on the evidence as it had been given, it was not open to the Crown to argue, nor for the jury to consider, that the four conversations were about a heroin transaction gone wrong. He said that the substance the subject of the previous transaction was said by the applicant to have gone "gooey" or "gluey", which Detective Sergeant Stanbury said was in all probability a reference to amphetamine and was unlikely to be a reference to heroin. He submitted further that the earlier transaction appeared to have involved Ivanov selling for $3800 an ounce, "gooey" or "gluey" drugs provided by Delovski, when, according to Stanbury's evidence, $3800 per ounce was the going price for amphetamines. Further, although in Detective Sergeant Stanbury's opinion, the references to imported cars were coded references to heroin, they could just as easily have been reference to amphetamines. Mr Traczyk submitted that in light of these considerations, it could now be seen that it was not open to the jury to use the earlier conversations as evidence of a previous transaction relating to heroin, and that being so, the evidence was not admissible, the prejudice was substantial and the jury should be discharged.
