Clause 7 then provides remedies where the tenant fails to do any work required under the clause, but makes no provision in a case of failure by the landlord.
24 There are difficulties with finding in cl 7.4 an express contractual basis for the obligation of the lessor to complete the construction of the premises. Further, and as a practical matter, the trial judge made no findings in relation to what works which were required under the interim occupation certificate were structural and what might qualify as work needed to make the property safe to use. The notice of contention did not identify any particular factual findings required in this Court and the matter was dealt with in a cursory fashion in written submissions (and indeed in oral argument), with the suggestion that "at least some of the outstanding works were needed to make the property safe" and without any concerted attempt to identify necessary works which might qualify as structural.
25 In terms of legal principle, both parties accepted the need to apply the principles stated by Mason J in Codelfa Construction Pty Ltd v State Rail Authority (NSW) (1982) 149 CLR 337. The Appellant argued that the implied obligation sought to be imposed upon it to complete the construction work might have been a reasonable term to imply, but it was not "necessary to do to give business efficacy to the contract": ibid at 346. The term may also be capable of clear expression, but its implication is not so obvious that it "goes without saying": ibid at 347.
26 Furthermore, the Appellant relied upon the established principle that it is "the business of the tenant, if he does not protect himself by an express warranty, to satisfy himself that the premises are fit for the purpose for which he wants to use them": Edler v Auerbach [1950] 1 KB 359 at 374 (Devlin J). As Lord Millett explained in Southwark London Borough Council v Tanner [2001] 1 AC 1 at 17-18:
"In the absence of statutory intervention, the parties are free to let and take a lease of poorly constructed premises and to allocate the cost of putting them in order between themselves as they see fit. The principle applies whether the complaint relates to the state and condition of the demised premises themselves or, as in the cases cited, of other parts of the building in which the demised premises are located. … The tenants accordingly accept that, in the absence of a statutory or contractual obligation to such effect, they cannot compel their landlords to install sound insulation."
27 The Appellant sought to draw support from the judgment of Balmford J in Carbure Pty Ltd v Brile Pty Ltd [2002] VSC 272, a case in which a tenant sought to have the landlord of a guest house known as Lorne Chalet carry out repairs of a structural nature. Although the tenant was not required to undertake structural repairs, the lease envisaged that if the premises were destroyed or damaged or rendered unfit for the permitted use, the obligation to pay rent might be suspended, or the lease might be terminated. However the lease expressly stated that the landlord "shall not be obliged to reinstate the premises": Judgment at [7]. The judgment provides a helpful analysis of the relevant legal principles, including a discussion of the decision of the English Court of Appeal in Barrett v Lounova (1982) Ltd [1989] 1 All ER 351 in which an implied condition to keep the outside of premises in good repair was imposed on the landlord as necessary in order to allow the tenant to conform to its obligations to keep the inside of the premises in good repair. Doubt about the authority of Barrett were given careful consideration. However, in Carbure itself, her Honour declined to imply a term requiring that the landlord undertake the relevant repairs.
28 No case was drawn to the attention of the Court in which the possibility of an implied obligation to complete construction of premises had been discussed. The Appellant argued that the absence of any such authority militated against the conclusion that such an implied term was appropriate, particularly in circumstances where the parties had negotiated with respect to the anticipated failure to complete before the commencement of the lease.
29 Taken separately, the complaints raised by the Appellant in relation to each stage of the argument accepted below, or now presented for the Respondent, have weight. In relation to reliance on the contractual terms, that is because the lease appears to be based upon an assumption that the construction of the building had been completed and, as a result, the premises were suitable for the purposes identified in the lease. If that assumption is so, the express terms do not cover completion of construction work, but the assumption may support the implication of a term to give effect to it. That does not deal with the separate complaint relating to the pre-contractual negotiations.
30 Further, the Appellant argues, the Respondent took a lease of the premises in a condition which was well understood by it. It negotiated a 50% reduction in rent to apply until the building was completed. The premises were used by the Respondent in the state in which they were leased for more than a year and, indeed, the Respondent continues to use the premises and actively resisted proceedings brought by the Appellant for possession. In those circumstances, there is no room, the Appellant argued, for an implied obligation to complete the construction of the premises.
31 Although the Court should be slow to imply a term into a contract such as a lease, in the circumstances set out above, and especially where the result might be seen as inconsistent with general law principles as to the extent of the obligations imposed on lessors and lessees, this is not a case involving the maintenance of existing facilities, nor the extent of obligations to repair such facilities. Those obligations are dealt with in express terms in the lease, particularly in clauses 6 and 7. It is for that reason that clauses 6 and 7 do not, in their terms, cover the present dispute: as a result, the Respondent's reliance by way of a notice of contention, on the express terms of cl 7.4 should not succeed.
32 On the other hand, the terms of cl 7.4 and the matters relied upon by the trial judge, as set out above, are relevant factors to be weighed in the balance in determining whether a term should be implied and what its content should be. However, the critical factor in favour of an implied term, with the content identified by the trial judge, lies in the express oral agreement with respect to rent. There was no dispute at trial as to the fact of an agreement, allowing the Respondent to pay a reduced rent; the dispute at trial related to the period and purpose of the indulgence. Significantly, neither party contended that it was to be permanent. Mr Colquhoun (for the Appellant) contended that he had agreed to allow the Respondent "to pay half rent until I think you are fully operational": [2005] NSWSC 1148 at [10]. That evidence was not accepted, the trial judge preferring Mr Atkinson's evidence set out above, which was corroborated by a receipt signed by Mr Colquhoun on or about 12 May 2003 for "rent being an interim rent until the building is 'complete'". Thus, both parties expected that the construction work would be completed. Nor was there any doubt as to which party was expected to complete it. Thus, as his Honour found at [14]:
"… on 31 March 2004 Mr Colquhoun gave Mr Atkinson a document setting out a list of work still to be done to complete the Premises. The document concluded, "On satisfactory completion of the list above full lease rent is to be paid less $1,000 per month as part payment for the goods supplied by Steel & Stuff" .
33 There is other material consistent with the Appellant's acceptance of its responsibility for the cost of construction work carried out during the course of the lease, including its agreement to pay for the replacement of the roller doors. Thus the only question is whether there was an implied obligation upon the Appellant to carry out the construction works as identified in the interim occupation certificate, within a reasonable time, or whether the Appellant was undertaking works from time to time to that end for its own purposes and without legal obligation to the Respondent. The terms of the oral agreement as to the temporary rent reduction, until the building works were completed, provides powerful support for the implied term.
34 Support for an implied legal obligation may be found not only in the express oral agreement, and the factors identified above, but also in the statutory context of the development of the premises. Thus, pursuant to s 109M(1) of the Environmental Planning and Assessment Act 1979 (NSW) ("the EP&A Act") a person must not "commence occupation or use of the whole or any part of a new building … unless an occupation certificate has been issued". A penalty is imposed for contravention of that prohibition. Although the City of Albury Council gave what was described as an "interim occupation certificate", apparently on 13 June 2003, that certificate required "outstanding works to be completed within sixty (60) days from the date of this Certificate". It is common ground that the bulk of that work was not carried out within the period specified. Although the response was somewhat dilatory, on 14 March 2005 the Council gave notice to the Appellant of an intention to serve on it an order under s 121B of the EP&A Act requiring completion of the works within 30 days and the obtaining of a "Final Occupation Certificate". The reason given in the notice was that the conditions in the development consent had not been complied with, the interim occupation certificate had expired and the building was, therefore, currently being occupied without an occupation certificate, the result of which might be "detriment to the health and safety of the occupants of the building and the environment". That situation, it may be inferred, had existed from mid-August 2003.
35 The effect of the implied term was to require the Appellant to take steps necessary to ensure that occupation of the building under the lease was lawful and in accordance with the conditions of the development consent under which the building had been constructed, prior to the negotiation of the lease. A term in that form was not merely reasonable and equitable, but necessary to give business efficacy to the lease and was a term of which it could properly be said that its inclusion "goes without saying". Such a term is not inconsistent with the express terms of the lease, but rather is necessary to allow them their proper scope of operation. The principles explained in Codelfa Construction are satisfied. It follows that the challenge to his Honour's conclusion with respect to the implied term should be rejected.
