14 In Kingsmede I stated, relevantly:
"9 It is first necessary to ensure that this is the appropriate time at which to deal with this interlocutory application. There is a long line of authority established at Full Bench level in this court and its predecessors to the effect that the respondents are required to establish that the claims made in the summons are so obviously untenable that they could not succeed, or are so manifestly faulty as not to admit of argument. This line of authority, which is exemplified by cases such as Nagle v Tilburg (1995) 51 IR 8, relies in turn on observations by Barwick CJ made in the High Court of Australia in General Steel Industries Inc v Commissioner for Railways (NSW) (1964) 112 CLR 125 at 128-129. This line of authority and the principles established are now so well-known in this court that it is not necessary that I deal with them any further.
10 Consistent with this line of authority I take the view that it will only be in exceptional cases that a court should consider a strike-out application going to jurisdiction before all of the relevant factual material has not only been filed but has also been subjected to forensic examination during the litigation process. It is the determination of this particular issue which in the context of these proceedings has given me the greater concern.
11. During the course of the hearing of the motion the applicant indicated through counsel that he did not intend filing any further affidavit material in chief, in addition to that which had already been filed in the proceedings. This affidavit material is directed solely to the lease arrangement including an ancillary arrangement dealing with car-parking space.
…
13. Whilst I have some doubt as to whether it is appropriate to deal with this matter at this interlocutory stage, on balance I am prepared to do so having regard to the manner in which the summons has been framed, the fact that all of the evidence in chief in support of the applicant's claim has been filed, and because of the view I take as to the substantive argument raised by the respondents. For these reasons I shall proceed to deal with the motion on its merits.
14. The application of s 106 of the Act to a commercial lease of premises has recently been the subject of consideration in the New South Wales Court of Appeal and by a Full Bench of this court.
15. In Mitchforce v Industrial Relations Commission [2003] NSWCA 151 Spigelman CJ considered a lease agreement of premises which were to be used for the specific purpose of a hotel. That agreement contained a number of provisions similar to the obligations imposed on the lessor and lessee in these proceedings, including provisions which his Honour described as contemplating the conduct of physical activity on the premises. These included on the part of the lessee: a covenant to repair and maintain the premises; to make good any breakages, defects or damage caused by lack of care; to repair and replace broken glass and damaged or broken services; to maintain the premises with particular reference to gutters, drains and pipes and the like; to paint the premises; and to make certain alteration and repairs other than structural repairs required by statute.
16. After considering relevant authorities Spigelman CJ concluded that although that lease agreement contemplated that work would be undertaken, in order to come within the definition of a contract for the purposes of s 106 of the Act it was necessary to find that the performance of work was a "purpose" of the lease agreement and that the agreement led "directly" to the performance of work in an industry. His Honour stated that the purpose of the agreement was to provide premises for the purpose of conducting a business, but the business was to be conducted by the lessee on the lessee's own account. His Honour emphasised that there was no express term which obliged the lessee to conduct the business. Mason P agreed generally with this reasoning of the Chief Justice. (I add for completeness that Handley JA dissented.)
17. The same lease document was also considered by a Full Bench of this court in Mitchforce Pty Ltd v Starkey (No 2) [2003] NSWIRComm 458. In a joint judgment, Wright J, President and Walton J, Vice President agreed with the reasoning of the Chief Justice which I have summarised above.
18. In my opinion the factual matrix which formed the basis of the Mitchforce litigation is relevantly indistinguishable from the factual circumstances which surround and apply to the lease agreement in these proceedings. A commercial lease of this kind, absent any positive requirement that work be actually undertaken so that the carrying out of work in an industry can be characterised as a purpose of the agreement, will not fall within the definition of a contract for the purpose of the s 105 definition so as to attract the jurisdiction of this court under s 106.
19. There are a number of decisions of this court, both at first instance and on appeal, which deal with commercial leases of premises, but which are distinguishable in a factual sense from the circumstances of these particular proceedings. Those decisions are dealt with in the judgment of the Chief Justice and in the joint judgment of the President and Vice President of this court in the Mitchforce litigation. It is not necessary that I traverse these judgments in any detail. They have been considered at appellate level in Mitchforce and relevantly distinguished. I merely observe that the factual circumstances in those decisions may also be relevantly distinguished from the factual circumstances which apply in the context of these proceedings."
