The defence under s 81(1)(b) of the Fair Trading Act 1987 (WA) focuses on the capacity of the director to prevent the offence by reasonable diligence, not on whether the director actually took reasonable precautions. The precautions and diligence must be directed at the avoidance of the specific offence, not merely at the general conduct of the business. Where a director is the architect of a scheme inherently fraught with the risk of misrepresentation and provides agents with false information, reliance on the agents' general training and experience will not establish the defence.
