(c) who is registered as a general insurer under the Commonwealth Insurance Act 1973."
9 Act No 51 of 2005 substituted "authorised" for "registered" to reflect changes in the Commonwealth Act. It was not suggested that this change was material.
10 The relevant insurers were not registered or authorised as general insurers under the Commonwealth Act and it was common ground that they were not insurers or general insurers as defined in s 247.
11 Section 6 of the Interpretation Act (NSW) 1987 relevantly provides that definitions in an Act "apply to the construction of the Act … except in so far as the context or subject-matter otherwise indicates or requires."
12 The principal submission of Mr Williams SC for the Commissioner was that a contrary intention, excluding the defined meaning of insurer, was disclosed by the text of ss 236(1) and (2), understood in the light of the structure and history of the legislation imposing insurance duty. These matters justified a wider meaning of the words "premium" and "insurer" in s 236 which would bring within the tax base premiums paid to insurers who were not registered or authorised under the Commonwealth Act.
13 Mr Williams relied on the scheme of the corresponding provisions in the Stamp Duties Act 1920, as amended, which were repealed and replaced by the Act. Section 88D(1) of the repealed Act, which broadly corresponds with s236 of the current Act, provided:
"(1) A person (other than a registered person) who obtains, effects or renews any insurance in New South Wales or elsewhere as an insured person with a person who is not a registered person … must, within 21 days after the end of the month in which the premium relating to the insurance is paid … lodge with the Chief Commissioner a return in the approved form containing such particulars and information as to the premium and the insurance as the Chief Commissioner may require."
14 The duty was payable on the lodgement of the return (s 88D(3)).
15 The repealed Act did not contain definitions of insurance or insurer, but defined premium widely in s 86(1) as meaning:
"… the total amount paid in New South Wales or elsewhere to an insurer in respect of insurance effected in New South Wales or elsewhere by the insurer without any deduction …"
16 If s 88D(1) had remained in force it would have supported the assessments under review. In terms of that section Qantas was an insured person which had effected or renewed insurance with a person who was not registered under the Stamp Duties Act.
17 Mr Williams submitted that the Act did not disclose an intention to narrow the tax base and the word "insurer" in s 236(2) was not limited by the definition to insurers registered or authorised under the Commonwealth Act. If the definition was not incorporated into s 236, and insurer had its ordinary meaning, the assessments would be correct.
18 The relevant Parliamentary material does not disclose an intention of narrowing the tax base for this duty.
19 The context to which reference should be made in interpreting a statute includes the existing state of the law when the Act was passed. In CIC Insurance Ltd v Bankstown Football Club Ltd (1997) 187 CLR 384, 408 the plurality said:
"… the modern approach to statutory interpretation (a) insists that the context be considered in the first instance, not merely at some later stage when ambiguity may be thought to arise and (b) uses context in its widest sense to include such things as the existing state of the law and the mischief which … one may discern the statute was intended to remedy. Instances of general words in a statute being so constrained by their context are numerous … if the apparently plain words of a provision are read in the light of the mischief which the statute was designed to overcome and of the objects of the legislation, they may wear a very different appearance. Further, inconvenience or improbability of result may assist the Court in preferring to the literal meaning an alternative construction which, by the steps identified above, is reasonably open and more closely conforms to the legislative intent."
20 See also Newcastle City Council v GIO General Ltd (1997) 191 CLR 85, 112; Network Ten Pty Ltd v TCN Channel Nine Pty Ltd (2004) 218 CLR 273, 280-1. In the former McHugh J said:
" a court is permitted to have regard to the words used … in their legal and historical context and, in appropriate cases, to give them a meaning that will give effect to any purpose of the legislation that can be deduced from that context. The context includes … the provision's legislative history."
21 The Parliamentary material is not of great assistance. The second reading speech of the Minister who moved the Bill in the Legislative Assembly said (Hansard 12 November 1997 page 1612):
"The primary purpose of the bill is to replace the current Stamp Duties Act with simple, clear and equitable legislation drafted in contemporary language and modern style."
22 It was not suggested that the relevant statutory context extended beyond Ch 8 which imposes insurance duty, and the relevant definitions in the Dictionary.
23 The critical difference between s 88D(1) of the former Act, and s 236(1) and (2) of the relevant Act, is that in the former insurer was not defined and had its ordinary meaning whereas at the relevant times the Act had a definition which limited its ordinary meaning
24 The Commissioner's argument requires "insurer" in the definition of premium and "insurer" in s 236(2) to be given its ordinary meaning, without the restriction introduced by the definition in s 247(2)(c).
25 Section 235 made the general insurer liable for the duty unless s 236 applied. It imposed liability for payment of the duty on every general insurer whether or not it was registered under the Act.
