4 His Honour began his consideration by having regard to the relevant provisions of the Act, including the objects of the Act and the context in which s 17 operates (at pars [9] - [21]). After finding that that there was "clear … evidence that the defendant retained some control over the truck while it was within the premises of Tibby Rose Auto", his Honour considered the requirement that the truck be "plant" within the meaning of s 17(1)(b) in the following terms:
26 The next element is the requirement that the truck and its equipment or, perhaps, the truck or its equipment, be plant within s 17(1)(b). It was in this area that the greatest controversy arose between the parties. Put simply, the prosecution submitted that the truck was plant and that it had been provided by the defendant for both use and operation of employees of Tibby Rose Auto during the course of performing their work. Accordingly, it fell within s 17(1)(b). The defendant submitted that the truck was not plant and, in addition, even if it had been plant it had not been provided for the use or operation of persons at work in the sense that it was not used by them as part of their plant to be used or operated in connection with carrying out their work.
27 The defendant relied on a discussion of the meaning of the word "plant" in the context of s 18 of the Act in a judgment which I gave in WorkCover Authority of New South Wales (Insp Gilbert) v R & D Panelform Pty Ltd (1997) NSWIRComm 189 (unrep 19 December 1997). In the course of that judgment I said in part:
"The word 'plant' is defined in s 4 of the Act in an inclusive manner as follows:
'plant' includes any machinery, equipment and appliance;
The inclusive nature of the definition of plant in s.4 compels an examination of the ordinary meaning of the word "plant". A useful description of this word is given by Lord Diplock in the House of Lords in Haigh v Ireland (Charles W) Ltd (1973) 3 All ER 1137. His Lordship said (at 1147-8)
'In the context of an Act which deals with what goes on in factories, 'plant' is an ordinary English word in common usage whose meaning is well understood. To quote the Shorter Oxford English Dictionary it means 'The fixtures, implements, and apparatus used in carrying on any industrial process'. As such it is to be distinguished from the products of the process or the objects on which the process is carried out. Save in its restriction to 'industrial' processes, which is appropriate to an Act in which the definition of 'factory' is confined to premises in which processes which would ordinarily be called 'industrial' are carried on, this definition is substantially the same as that stated by Lindley LJ in Yarmouth v France (1887) 19 QBD 647 at 658:
' . . . in its ordinary sense [he said], it includes whatever apparatus is used by a business man for carrying on his business, - not his stock-in-trade which he buys or makes for sale; but all goods and chattels, fixed or moveable, live or dead, which he keeps for permanent employment in his business . . .'
It was this ordinary meaning which he ascribed to the word 'plant' as used in the Employers' Liability Act 1880, in a context in which it was not confined to plant of employers whose business consisted of carrying on industrial processes. The marked preference which courts habitually show for citing judicial in preference to lexicographers' definitions of ordinary English words, even when they are not legal terms of art, has led to the acceptance of Lindley LJ's definition as being the meaning of the word 'plant' where it has been used without any express statutory definition in a variety of enactments, particularly those dealing with taxation of industrial enterprises.
It is a definition of a physical object by reference to the use to which it is being put. Where, as in the Factories Act 1961, all references to 'plant' are to plant within a factory in which an industrial process is carried on, the only relevant use, in my opinion, is that to which the physical object is being put in that factory. If it is there as part of the apparatus for use in carrying on the industrial process undertaken on those premises, it is 'plant' within the meaning of the Act even though it may be temporarily out of use or in the course of installation, repair or removal. If it is there for the purpose of being subjected to that industrial process it is an 'article' as that term is used in the definition in s.175 to describe the physical objects on which are carried out those industrial processes which qualify the premises where they are undertaken as a 'factory' within the meaning of the Act; it is not 'plant', whatever may be the use to which it has been previously put or may be subsequently put elsewhere.'
The above extract emphasises that it is necessary to have regard to the context in which the word occurs in order to establish its correct meaning. It is for this reason that I shall refrain from considering the many taxation cases dealing with the meaning of that word because in most cases the courts there were considering the meaning of plant in the context of plant used for the purpose of gaining assessable income. This has led in many cases to a discussion as to whether a building might be plant. Another example is provided by the well known case of Yarmouth v France (1887) 19 QBD 647 in which it was held that a horse which had injured an employee was plant used in the business of the defendant."
28 The 2nd Ed of the Macquarie Dictionary defines plant, relevantly, as: "the equipment, including the fixtures, machinery, tools, etc, and often the buildings, necessary to carry on any industrial business: a manufacturing plant.... the complete equipment or apparatus for a particular mechanical process or operation: the power plant of a factory".
29 The sense in which "plant" was discussed in the authorities referred to above and in the Macquarie Dictionary definition indicates that the word is descriptive of items that are intended to be used or operated in the course of carrying on activities, inferentially being activities of a business nature or something analogous to a business nature. The word in this sense conveys a meaning more indicative of something which is used or operated to enable work to be carried out.
