12 The Commissioner's argument, shortly stated, was that s 178(1) does not prescribe that a premium is "paid" for the purposes of s 179 only if the events contained in s 178(1) and (2) occur. According to the Commissioner, s 178 ensures that the insurer's liability under s 180 to pay the duty arises only at a time when the receipt of the premium is within the knowledge of the insurer. The Commissioner submitted that this construction was consistent with the intention of Part 2 of Chapter 8 to impose duty on FSLs, whether paid by the insurer or by an insured directly to the fire authorities. It was also argued that this construction is consistent with, and gives effect, to s 177(2) of the Act which encapsulates the position under the CFA Act and the MFB Act that an insured has the liability to pay the FSL in given circumstances. It was submitted that if Shell's argument was correct, s 177(2) would otherwise be ineffectual in relation to an insured, because it would mean that the FSL would only be subject to duty if it was received by the insurer. Thus it would have no operation where the insured owes the liability directly to the fire authorities. Finally, it was argued that the trigger for payment of the duty on the FSL is the payment of the premium to which the FSL relates.
