(1) The line of authority exemplified by Bartolacci and Kwong was wrong in that it determined that there is power within the section to vary a contract which does not itself provide for the performance of work. That is, where a contract is found to be a collateral contract within the meaning of s 105, that collateral contract itself must provide for the performance of work if that contract is going to be capable of variation under s 106. The reality of the circumstances before the court involved the sale of a continuing business. The employees of such a business, as a fundamental part of the asset being sold, must necessarily be contemplated in the sale of business agreement. The sale of business contract will, for this reason, contain provisions that "have an employment flavour". However, the question which must be asked is, 'under which contract is the work performed'. Mr Graves contended that in these circumstances, the relevant agreement providing for the performance of work was the service agreement. It was "tortuous in the extreme" to permit attack on the sale of business agreement as, on his submission, it was beyond the competence of the section.
(2) Whilst the definition within s 105 plainly contemplates that an 'arrangement' whereby a person performs work in an industry will fall within the purview of s 106, the line of authority, typified by Kwong, is wrong in that it considers such an arrangement can consist of a series of contracts which includes one specifically for the performance of work in an industry. In this case, the work of the first respondent was being performed not pursuant to the broad arrangements involving the sale of the business, but specifically pursuant to the terms of the service agreement only. In these circumstances it is wrong to look to some broader notion of an "arrangement".
(3) In a practical sense it was conceded that the two contracts were connected. Further, it was conceded that there was nothing which would prevent more than one contract leading to the performance of work. However, when looking at the arrangements in relation to the operation of the section, there was no "necessary connection, condition or link" as was identified by Hungerford J in Bartolacci, leading to the performance of work in an industry. Here, as in Kwong, there was a work contract, and other separate contracts which did not directly provide for the performance of work. For the Court to adopt some other approach was an "absurdity" and amounted to a circumvention by the Commission of the authority of the Court of Appeal in Production Spray Painting. The impugned line of authority, in so far as it permits contracts to be varied which do not provide directly for the performance of work in an industry, is contrary to the authority of Production Spray Painting and therefore wrong.
32 Mr Kite SC, who appeared with Mr J Keasing of counsel for the respondents, submitted that leave should be refused, as the impugned decision was of an interlocutory nature and involved the application of well established and well understood principles. In short, there was no error of principle warranting the granting of leave to appeal: Dun and Bradstreet (Australia) Pty Ltd v Robbie (1999) 91 IR 150 at 151.
33 Senior counsel submitted that the appellant adopted the wrong construction of the section when asking whether each component of an "arrangement" itself led directly to the performance of work in a relevant industry: Custom Credit Corporation Ltd v Goldsmith [1976] AR (NSW) 98 at 131, Smith v Craig Mostyn & Co Pty Limited (1984) 2 NSWLR 393 at 399C, Bartolacci v Permanent Custodians Limited (1992) 44 IR 388 at 394 - 395, and Kwong v Stone Microsystems (Aust) Pty Ltd (1996) 82 IR 255 at 309 - 310. Both collectively, as constituting an "arrangement", and individually, the sale of business agreement and the service agreement led to the performance of work in an industry and were therefore a "contract" as contemplated by s 105.
34 On Mr Kite's submission, for the two agreements to constitute an "arrangement" as contemplated by s 105, there needed to be a sufficient connection between the various contracts which led to the performance of work: Kwong v Stone Microsystems. Such a connection was manifestly clear, having regard to clause 22 of the sale of business agreement. Further, when one has regard to the clauses of the service agreement under the heading "Background", the intentions of the parties to these transactions was abundantly clear. The two agreements were, it was submitted, on their face, inextricably linked. Whilst each was an enforceable contract in its own right, they each formed part of an arrangement whereby E World would be sold as an ongoing business.
35 Such a construction is supported by the nature of the payments for goodwill on an ongoing basis, calculated as they were by reference to business performance. The transactions relevant to this case were not a mere "straight out sale" as in the case of Production Spray Painting. On Mr Kite's submission, the appellant's challenge to the relevant line of authority was premature - leave to appeal should be refused.
Consideration
36 Appeals to the Full Bench of this Commission are not of right but require the grant of leave: s 188(1). The principles surrounding the granting of leave are well settled: see De Simone Consulting Pty Ltd v Ison [2000] NSWIRComm 269 referring to Knowles v Anglican Church Property Trust (No.2) (1999) 95 IR 380. It is also well settled that leave will not lightly be granted. Further, interlocutory appeals in this Court and in courts of general jurisdiction, are to be discouraged: Re Social & Community Welfare Services (State) Award and Other Awards (1984) 9 IR 305; Parramatta City Council v Health and Building Surveyors Association (NSW) (1988) 26 IR 398 at 401 - 402; Re Laundry Employees (State) Award (No 2) (1993) 49 IR 91 at 103; Chamber of Manufactures of New South Wales v Australian Chamber of Manufactures, New South Wales Branch (1994) 56 IR 307 at 310 - 311; Caltex Petroleum Pty Limited v Harmer (1999) 92 IR 264; Bell v Macquarie Bank Limited (No 4) (1999) 93 IR 191; Metrocall Inc v Electronic Tracking Systems Pty Limited (No 2) (2000) 102 IR 309; Integral Energy v Allen (2001) 107 IR 456; Ridge Consolidated Pty Ltd v WorkCover Authority of New South Wales (Inspector Mauger) (2000) 100 IR 156, and more recently in National Australia Bank Ltd v Cassino [2002] NSWIRComm 241. As was stated by the Full Bench in Integral Energy v Allen :
[13] In Caltex Petroleum Pty Limited v Harmer (1999) 92 IR 264 the Full Bench (Wright J, President, Walton J, Vice-President and Hungerford J) observed that "[t]he predecessors of this Court and Commission, in line with the approach of the ordinary courts, have generally deprecated and discouraged such interlocutory appeals." Leave will rarely be granted if the interlocutory decision is of a procedural nature: Metrocall Inc v Electronic Tracking Systems Pty Limited (No 2) (2000) 102 IR 309. Moreover, the raising of a jurisdictional issue does not, of itself, establish a basis for the grant of leave: Knowles v Anglican Church Property Trust (No 2) (1999) 95 IR 380 at 381.
