The court made observations on the doctrine of strict liability in criminal law, noting that even in jurisdictions that recognize strict liability for public welfare offences (such as public health legislation, safety regulations, contamination prevention, motor carriage regulations), courts are generally reluctant to imply that the legislature intended strict liability because it is directly contrary to the basic principle that there should be no liability without fault. The court referenced academic criticism by Burchell and Hunt expressing doubt whether strict liability can be justified in terms of social and legal policy. The court also observed that even where strict liability is imposed, liability remains dependent on proof of the actus reus (the voluntary and unlawful act), and defenses that exclude unlawfulness (such as necessity, impossibility, or authority) remain available to the accused, making liability 'strict' rather than 'absolute'.
