43 I do not accept the submissions made on behalf of the lessors, for the following reasons.
44 It is common ground that the rental value direction in cl. A6.3(i) requires the valuer to have regard to, amongst other things, incentives in adjusting rentals for comparable premises. In the absence of a specific direction to take no account of incentives, such as that contained in the 1991 lease, there is no basis for the lessors' contention that the valuer was obliged to take the fourth step referred to in the lessors' written submissions and "gross up" the rental value of the most comparable premises identified by him. In my opinion, the valuer was simply required to determine the market rental in the context of his findings concerning the rental values of comparable premises and other relevant matters.
45 In my opinion, when the lease is construed in the light of the surrounding circumstances to which I have referred, commercial common sense dictates that the valuer was entitled to treat the two expressions as synonymous. I do not accept the lessors' submission, which would have the effect that the parties intended that the lessee, who received no incentive to enter into the lease, would pay rental equal to the amount actually paid by other lessees of comparable premises in the market, where those lessees received incentives to enter their leases. No such intention should be attributed to parties to a commercial lease in the absence of clear and unambiguous language requiring that result. In my view, when considered in the light of the surrounding circumstances, the language of cl. A6.3 does not require that result. I am of this view for the following reasons.
46 First, in my opinion any distinction which the parties may have intended to draw between market rental and market rental value has been negated by the inclusion of the rental value direction contained in cl. A6.3(i) and the exclusion of any direction to the valuer to ignore incentives. As I have said, such a direction was given in the 1991 lease and the parties to the lease were aware of this.
47 Second, if the parties had intended such an uncommercial result, an unambiguous direction to this effect could have been included in the lease. For example, the lease could have provided that the rent was to be determined by reference to the rentals paid for comparable properties, taking no account of any incentives paid or payable to the lessees of such comparable properties. This is what was done in the 1991 lease. The exclusion of such clear words from the current lease is a strong indication that the parties did not intend that the valuer should calculate market rental in the manner contended for by the lessors.
48 Third, the lessors' own submissions accept that the expressions "market rental" and "market rental value" do not always have the meanings contended for by the lessors. The cases relied upon by the lessors to establish the meanings of the two expressions make it clear that it is for the Court to discern the intention of the parties to the lease in question by reference to ordinary principles of contractual interpretation. This principle applies with particular force to rent review clauses, where it is common for parties to use language that may produce an artificial result.
49 In my view, the distinction between market rental and market rental value articulated in Re McCafferty does not apply to the lease in this case. The report of that case does not disclose whether the lessee was paid an incentive to enter into the lease. Further, the lease in Re McCafferty expressly and unambiguously directed the valuer to disregard any incentives payable by a lessor to a lessee in fixing the "market rent". In my view, the statements in Re McCafferty as to the difference between "rental" and "rental value" do not express general definitions of those terms to be applied in every case. If, contrary to my view, the statements by Ambrose J in that case as to the difference between "rental" and "rental value" were intended to be of general application, I would respectfully decline to follow those statements. It is common for rent review clauses to prescribe a highly artificial method of determining rent. Accordingly, the same words may have different meanings in different leases. Even identical rent review clauses may be interpreted differently in the context of two different leases, depending upon matters including the surrounding circumstances, commercial common sense and the other terms of the leases.
50 In my view, I should treat the consideration of the distinction between rental and rental value by Eames J in the Australian and Overseas Telecommunications case in the same way. Indeed, Eames J noted that the assistance which can be gained from the construction of rent review clauses in other cases "must be necessarily limited."[17]
51 The case of Ropart Pty Ltd v Kern Corporation Ltd[18] illustrates the way in which the ordinary meanings of words can be altered by specific directions given in a rent review clause. In that case, the valuer was appointed to establish "annual rental value." The lease provided that the valuer was required to have regard to the "annual rental value" of comparable premises. However, the valuer was instructed to take no account of the fact of any premium paid or payable to the lessee to take the lease, or which was paid or payable to the lessee of any comparable premises. Having regard to the protocol established by the specific directions to the valuer, the Court of Appeal in New South Wales concluded that the valuer was required to ignore incentives in considering rental value of the premises in question, and in considering rental values of comparable premises.[19] The specific directions to the valuer to ignore incentives in Ropart were in virtually identical terms to the directions which were contained in the 1991 lease, but which have been excluded from the current lease in this case.
Conclusion
52 For the above reasons, I find that the rental determination was in accordance with the lease. The proceeding will be dismissed.
