That qualification has remained a part of the relevant section ever since.
55 "Public street" had been defined by the Motor Vehicles (Third Party Insurance) Act 1942 itself to have same meaning as that provided by the Motor Traffic Act 1909. The Motor Traffic Act 1909, which was the first specific motor traffic legislation enacted in New South Wales, in turn adopted the same definition of "public street" as its earlier predecessor, the Metropolitan Traffic Act 1900 (Act No 8, 1900). Section 4 of the latter stated that "'public street' means street, road, lane, thoroughfare, or place, open to or used by the public" [emphasis added]. The Metropolitan Traffic Act was the first step, as the Second Reading Speech in the Legislative Assembly makes plain, towards centralised general regulation of vehicles, drivers and other users of roads under the control of the Metropolitan Police force. Precipitating it was concern for public safety due to the growing congestion of streets in the metropolitan area.
56 Prior to enactment of the Metropolitan Traffic Act in 1900 regulation of traffic had been variously the province of: (i) the Metropolitan Transit Board (with responsibility for public vehicles such as taxicabs for hire: Public Vehicles Act 1899, and (ii) municipal councils (with responsibility for local traffic on roads within their boundaries other than main roads of the colony): Municipalities Act 1897 Pt XIV, Div 1; Sydney Corporation Act 1879, Pt V). That legislative regime was somewhat piecemeal and unsatisfactory. The earlier statutes did not use the words "a place open to or used by the public". The fullest definition was provided in the Municipalities Act 1897, which comprehended a formal legal user or enjoyment in favour of the public; s175. However, that definition was not carried over into the new statute.
57 Under the mandatory third-party insurance scheme in its various guises, it is unlawful for an uninsured vehicle to be used upon a public street or road. This effectively cast an obligation on persons who intended to use a vehicle on such a road to obtain insurance. Since it was to be assumed that persons will generally act lawfully, the legislation is beneficial in the sense that it gives people an expectation that, if they are injured by a vehicle on a public street, they will not be out-of-pocket and will be able to access a compulsory insurer for a remedy. Conversely, that expectation would be unfounded in the case of people using places which are not roads in that sense. Such users simply could not be confident that the vehicles they encountered were being used unlawfully if not registered and insured. To use the example referred to in the Minister's Second Reading Speech, a person walking through the paddocks of a private farm simply cannot know that any vehicle he or she encounters is required to be insured. It would not accord with the purpose of the legislation to make the nominal defendant liable for accidents occurring in such circumstances. Although the meaning of road cannot depend upon the subjective question of whether a person using a place would expect to encounter insured vehicles, this feature of the legislation should be borne in mind when considering whether any particular place is a public street or road under the scheme.
58 It is still the case that it is an offence to use an uninsured motor vehicle on a road: s8 MAC Act. It is still the case that it is an offence to use an unregistered motor vehicle on a road: s18 Road Transport (Vehicle Registration) Act 1997. It is still also the case that a vehicle is only eligible to be registered if the requirements of applicable third party insurance legislation has been complied with in respect of the vehicle: Part 2 Div 2, Road Transport (Vehicle Registration) Act 1997; clause 7, Road Transport (Vehicle Registration) Regulation 1998. This combination of provisions provides both the carrot and the stick that make the compulsory third party insurance scheme workable. In order lawfully to drive on public roads, a motorist must obtain registration and insurance. Corresponding to this, the liability of the nominal defendant with respect to uninsured motor vehicles only extends to liability in respect of motor vehicles, used on roads, as defined, which (a) are exempt from registration, or (b) which should have been (and are substantially capable of being) registered: s33(5) MAC Act. In this way, the liability of the nominal defendant vindicates the assumption of the injured claimant that the vehicle was being lawfully used.
59 In one important respect, the liability of the nominal defendant is narrower than that of other third-party insurers. That is illustrated by Nominal Defendant v Merritt (1988) 48 SASR 278 per Jacobs J at 283 dealing with legislation of a similar ambit. For the nominal defendant to be liable, the accident itself must have occurred on a road. By contrast, the terms of the current third-party policy, prescribed by s10 MAC Act (cf s9, Sch 1 MA Act), expressly provide that no significance attaches to where the accident occurred. The policy must simply insure, in the case of vehicles not subject to an unregistered vehicle permit, in respect of "death or injury to a person caused by the fault of the owner or driver of the vehicle … in the use or operation of the vehicle in any part of the Commonwealth (whether or not on a road)": s10(1)(a) [emphasis added]. It would appear that the words in parenthesis were included by way of emphasis. This policy without them would have had the same effect, given the earlier broad and unqualified reference to "any part of the Commonwealth". The words in parenthesis did not appear in the earlier Motor Vehicles (Third Party Insurance) Act 1942, as amended, when prescribing the policy that was required to be issued by the Government Insurance Office. However, the ambit of that policy was substantially the same.
60 Thus the legislature determined to extend the beneficial impact of the mandatory third-party insurance scheme beyond covering accidents occurring within the ambit of the statutory obligation to obtain insurance. The liability of the nominal defendant is, however, otherwise strictly co-ordinate with the obligation to obtain insurance. This is appropriate as it is the insurer of last resort which, upon the earlier analysis, is required to do no more than vindicate the assumption of members of the public that others are behaving lawfully.
61 One question raised squarely by this case is how much narrower the nominal defendant's liability should be. If the expression "open to or used by the public" were given a broad interpretation, the gap between the nominal defendant's liability and the liability of other insurers would be minimised. But error lies in narrowing the gap too far, by recourse to a purposive interpretation directed exclusively to protecting those injured by motor vehicles wherever an accident may befall. So to do renders the qualifying words "open to or used by the public" meaningless. There must be a difference between a "place open to or used by the public" and merely a "place". If the legislature had wanted to make the nominal defendant's liability co-extensive in that way with that of ordinary insurers under the scheme, it could have said so plainly. But that would be to make it do more than fill the perceived lacuna which the amendment in the Motor Traffic (Amendment) Act 1951 (No 59, 1951) was expressly enacted to fulfil. Though a question of fact and degree, there must be a point where a person who is injured by a motor vehicle is unable to take comfort from the ready accessibility of insurance, under a discrimen based on the public nature or character of the road.
62 In the light of this, it is helpful to consider in summary form various classes of injuries and their consequences under the legislation:
(a) A person injured by an insured motor vehicle, whether on a "road" or not, will primarily have recourse against the third-party insurer: cf Pt 4.2, s72(2)(a) MAC Act;
(b) (i) A person injured by an uninsured motor vehicle, which is exempt from registration or should have been and is substantially capable of being registered, where the injury occurs on a "road", will have recourse primarily against a third-party insurer, in the form of the nominal defendant.
(ii) The nominal defendant can then seek to recover amounts paid out by it as a debt from the owner and/or driver.
(iii) The nominal defendant will be unable to recover if the motor vehicle was not required to be registered, was exempt from registration or was not required to be insured: cf ss 33, 39, 72(2)(a) MAC Act;
(c) A person injured by an uninsured motor vehicle, not on a "road", will have recourse only against the owner or driver of the vehicle: cf s72(2)(b) MAC Act.
