[3] The appellant was employed by the complainant company as a security officer, sometimes delivering and picking up cash in an armoured vehicle with others. A bag called a replenishment bag containing $40,000 in cash was kept in the complainant company's armoured vehicle so that security could replenish empty automatic teller machines. The bag was locked by a zip with a metal catch covered with a numbered plastic seal which could be used once only. After the $40,000 was placed in the bag, the bag was zipped and secured with the metal catch and plastic seal and the bag could not be reopened without breaking the plastic seal. When an automatic teller machine was replenished, a security officer would break the seal, remove the money and refill the ATM. This procedure would be noted, recorded and observed by another officer. The bag would then be taken back to the complainant company and the responsible person would note the funds used and check this against the money in the bag. The amount in the bag would again be made up to $40,000, placed in the replenishment bag, the zip covered with a new numbered plastic seal, and the bag returned to the armoured vehicle. The only time a check was made on the contents of the bag was when an automatic teller machine was to be filled with cash from it. The bag would often remain in secure custody in the armoured van with the seal intact throughout an entire shift. At the end of the shift the bag was taken to the complainant company's dispatcher where the seal was checked by a security officer to ensure it was still intact; the bag was then secured in a vault until taken out on another shift. Weeks could pass without the bag being opened and its contents checked; if the seal appeared to be in tact when checked at the end of each shift, it was assumed that the $40,000 was still in the bag. The system only provided for checking the contents if the bag had been opened to replenish an ATM or if the seal did not appear to be intact.
