In prosecutions under s10 of the Copper Control Act (or similar possession offences), the State must prove beyond reasonable doubt not only possession of copper, but also that there was reasonable suspicion that the copper had been stolen, and that the accused failed to give a satisfactory account of possession. The burden of proof remains entirely with the State; the accused bears no onus to prove the truth of any explanation given. An inference of guilt can only be drawn from proved facts that exclusively point to the guilt of the accused. Mere suspicion, without supporting evidence, is insufficient to establish that copper was stolen. Where an accused provides an explanation for possession (even if improbable), and that explanation is corroborated or not rebutted by State evidence, and no investigation is conducted to disprove it, the accused is entitled to acquittal if there is any reasonable possibility the explanation is true. A conviction based solely on an admission of knowledge of possession and intent to sell, without proof that the items were stolen, fails to establish all essential elements of the offence and is not in accordance with real and substantial justice.
