"Now, in order to prove that offence the Crown must prove a number of obviously constituent elements. First it must prove that an importation occurred. Second, it must prove that what was imported was cannabis. It must prove that cannabis is a prohibited import. It must prove that the quantity of cannabis was not less than a trafficable quantity. And fifthly and finally it must prove that the accused was knowingly concerned in the importation. The third and fourth elements may be easily disposed of. As a matter of law I tell you that cannabis is a prohibited import and that a trafficable quantity consists of 100 grams. That is the law, and I tell you that that is the position. It is the Crown case that a considerable quantity, far more than the defined trafficable quantity, was imported in the crate. It alleges 9.2 kilograms was imported by air. There was no argument or issue raised about the quantity, nor that what was imported was cannabis. And no one suggests that less than a trafficable quantity of cannabis was imported. So, this element also is established or may be taken to be established. Importation occurs when an aeroplane from overseas lands and unloads its cargo at an airport. At that stage the goods have come into the country, which is the ordinary meaning of the word 'import'. However, the act of importation is not complete until the goods have been cleared by customs and quarantine, if applicable, and released for delivery. In this case the act of importation was complete when a female who signed the cartage advice in the name of Lori Van-Dore, took delivery of the crate, and drove out of the bonded warehouse of Hellman Worldwide Logistics in Lambeck Drive, Tullamarine. That is when the importation is complete. However, the expression 'knowingly concerned' is not restricted to the bare act of importation. For the purpose of this Act the words 'knowingly concerned' mean criminally involved in. In order to be criminally involved in or knowingly concerned in, two things are necessary. First, an act or acts of the accused which are related to the importation of the goods. There must be a connection between the accused's act or acts and the importation of the goods. Such an act or acts might occur before the actual importation, such as arranging the shipment of goods or even buying the goods with the intention to import them. Or it might occur after the goods have been unloaded from the aeroplane, such as attempting to clear them through customs, or driving them from a bonded warehouse after customs clearance. But the act or acts must be connected to the importation. Acts wholly referable to a later disposition of the goods, such as prior to [sic] selling the cannabis in Melbourne or Sydney, are not acts concerned in the importation of the goods. Merely being in possession of the cannabis after its importation is complete, and having done no acts in connection with its importation, is not to be concerned with the importation. Second, the accused must have a criminal intent, a state of mind which the law calls a mens rea, a guilty mind. In this case the guilty mind of the accused is constituted by a knowledge that the goods consist of a prohibited import of a particular character, namely a narcotic substance, and an intention that such an importation shall occur. In other words, knowingly involves a concept of design on the part of the accused. It involves the accused having actual knowledge of a plan to import cannabis into Australia and an intention that such importation take place. It is not enough for an accused to be simply aware that something is going on. Nor is it enough for the accused merely to know what Mwajinka intended. That is not being involved in or concerned in the importation of cannabis. There is, in such a case, no intention present that the importation shall take place. The evidence of such an intention will usually be inferred from a proven connection between the accused and the act or acts of the importation. When the criminal law speaks of knowledge it normally means belief. Suspicion is not enough. Certainty can rarely exist. Guilty knowledge is the state of mind of one who entertains a guilty belief. In this case the belief must be connected to the thing forbidden by law, namely the prohibition of the importation of narcotic substances. And finally, the act or acts of the involvement with the importation must be done with an intention to further the unlawful purpose of bringing in a prohibited import into the country."
