During the course of argument, his Honour said that that basis was "most logically consistent" with the jury's acquittal on the importation charge and conviction on the possession charge. We cannot agree. As his Honour told the jury before consideration of the importation charge, "... there needs to be knowledge that there was an imported drug in the container" and, he went on, "some conduct in relation to it with that knowledge". Importantly, on the importation charge, in contrast to the possession charge, the prosecution could not rely on a statutory presumption that the drug was known to be imported but had to prove that knowledge: see subsection 233B(1A) and compare subsections 233B(1)(c) and (d) of the Customs Act 1901 (Cwlth). The jury might have been convinced that Marshall and Lansdowne knew that the drug was in the container when they took possession of it at Rocklea, but acquitted them on the importation charge because they were not convinced that they knew that the drug was imported.
