The rent review issue
3 This appeal concerns the construction of a rent review clause in an agreement of lease ("the Lease").
4 The Lease was entered into in 1973 between the Maritime Services Board of New South Wales and the appellant ("ADC"). In terms thereof ADC was granted a leasehold estate in the property known as 189 Kent Street Sydney ("the Property"). The term of the Lease runs from 23 November 1972 to 31 May 2062; it is, therefore, for a period of more than 90 years. Prior to the Lease, a large office building had been erected on the Property and that building has remained on the Property until now.
5 Prior to 1996 the Marine Ministerial Corporation acquired the Property from the Maritime Services Board. After 1996 the Property was sold to the respondent ("Barana").
6 The Lease in its original form contained a rent review clause (the "original rent review clause") that provided for five yearly rent reviews and was in the following terms:
"… TO BE HELD by the Lessee as tenant for the term … at a rental of … ($26,608) per annum for the period commencing on [23 November 1972] and expiring on [31 May 1973] and thereafter for each succeeding period of five years at the yearly rental for the preceding five years increased by eight per cent of the amount of increase (if any) in the unimproved capital value of the land since the commencement of each such preceding period of five years all such rents to be paid by equal monthly instalments in advance to the Board at its head office in Sydney on or before the first day of each and every month during the said term PROVIDED that such unimproved capital value as at [31 November 1972] shall be taken as ($360,000) and thereafter shall be valued by the Valuer General in accordance with the Valuation of Land Act 1916 and any amendment thereof …"
7 On 16 December 1996 the Lease was varied by a document entitled "Variation of Lease". The Variation of Lease replaced the original rent review clause with a new and different rent review clause (the "new rent review clause"). The new rent review clause required rent reviews to be held every five years as from 1 June 1998 and provided:
"D. From (and including) each Review Date the annual rent payable shall be the sum which is eight per cent (8%) of the Value of the Land as at that Review Date."
8 Clause C of the Variation of Lease provided the following definitions relevant to the new rent review clause:
'''Value of the Land' means the capital sum which the fee simple of the land hereby leased might be expected to realise if offered for sale on such reasonable terms and conditions as a bona-fide seller would require assuming that the improvements, if any, thereon or appertaining thereto, other than Land Improvements, had not been made. Despite anything in the preceding sentence, in determining such capital sum it will be assumed that:
(a) the said land may be used or may be continued to be used, for any purpose for which it is or was being used, or for which it could be used, at the relevant Review Date; and
(b) such improvements may be continued or made on the land as may be required in order to enable the land to continue to be so used
but nothing in this clause prevents regard being had, in determining such capital sum, to any other purpose for which the land may be used on the assumption that such improvements, if any, other than Land Improvements had not been made;
…
'Land Improvements' means:
(a) the clearing of land by the removal or thinning out of timber, scrub or other vegetable growths;
(b) the picking up and removal of stone;
(c) the improvement of soil fertility or the structure of soil;
(d) the restoration or improvement of land surface by excavation, filling, grading or levelling, not being works of irrigation or conservation;
(e) the reclamation of land by draining or filling together with any retaining walls or other works appurtenant to the reclamation; and
(f) underground drains;
…"
9 On 1 June 2003 a rent review was carried out to determine the new rent as from that date. A valuer, Mr Gothard, was appointed for this purpose and brought in a valuation of $25,000.000 as the "Value of the Land". He applied the following methodology in valuing the Property:
· "The property which I am to value is the [fee] simple of the land. This means that, in assessing the value I am to assume that the Lease from which this task derives does not exist.
· I am to assume that the improvements which occupy the land do not exist however, I am still required to recognise any Land Improvements. The excavation on the land is considered to be a Land Improvement and therefore should be included in the value.
· The value is to reflect the highest and best use of the land. I should state that I believe I am required to adopt a reasonable approach to the highest and best use based on the planning and development controls at the valuation date.
· Whilst considering the value based on the highest and best use I am also required to have regard to the value of the land for its existing use. In this valuation exercise I am to assume that the land may continue to be used for a building which is identical in type, use, size and style to that which is presently erected thereon."
10 ADC contended that the rent review miscarried on the ground that Mr Gothard's valuation of the land was not conducted in accordance with the Lease. ADC brought proceedings seeking a declaration to that effect.
11 Before Palmer J ADC submitted that Mr Gothard's valuation failed to apply the valuation methodology prescribed by the definition of "Value of the Land" in cl C of the Variation of Lease. The basic proposition advanced by ADC was that Mr Gothard was wrong to assess the value of the land on the assumption that the Lease did not exist. ADC contended:
"In the case of property which is subject to the Real Property Act 1900 (NSW), the unambiguous meaning of the words 'fee simple of the land' is the interest of the registered proprietor in that property, subject to all encumbrances recorded on the title to that property, such as easements, covenants, mortgages and leases.
Accordingly, and in the context of the Lease and the Variation, Mr Gothard, in determining the 'Value of the Land', was required to determine the interest held by Barana in the Property, subject to all recorded encumbrances which relevantly included the Lease."
12 Palmer J rejected ADC's submissions. His Honour pointed out that the definition of "the Value of the Land" in the Lease was, subject to insignificant differences, the same as the definition of "value of land" in s 6A of the Valuation of Land Act 1916 (NSW) and (prior to the amendment of the Act by the introduction of s 6A) its predecessor (the former s 6). His Honour considered that the parties, by adopting a definition of value of the land that was taken from and so similar to s 6A and s 6, intended that the Lease definition was to be given the same settled interpretation as had been given by the courts to these sections. His Honour referred to a body of authority that, he said, supported this approach, including McCann v Switzerland Insurance Australia Ltd (2000) 203 CLR 579 at 601 and Ferris v Plaister (1994) 34 NSWLR 474.
13 His Honour then proceeded, after referring to Royal Sydney Golf Club v Federal Commissioner of Taxation (1955) 91 CLR 610, Sydney City Council v Valuer-General (1956) 1 LGRA 229 and Gollan v Randwick Municipal Council [1961] AC 82, to conclude:
"[I]n accordance with the construction which the Courts have placed on the words of s 6(1) [of the Valuation of Land Act ], the words 'fee simple' in the lease definition of "Value of the Land" should be construed as requiring the Lease itself, and any restrictions on use created thereby, to be excluded from consideration in the valuation exercise, as Mr Gothard did."
14 His Honour further considered that the construction the courts have placed upon s 6A and s 6 of the Valuation of Land Act "requires that for all relevant purposes of valuation the restrictions on use imposed by the Lease are to be ignored". His Honour referred to Sonnerdale v Valuer- General (1953) 19 LGR (NSW) 211, Wunderlich Ltd v Valuer-General (1959) 5 LGRA 50, Ritchie v Valuer-General (1961) 21 LGRA 296, Pye v Valuer-General [1973] 2 NSWLR 385 and other cases, and said:
"In accordance with these decisions, it is clear … that the purpose and effect of the second sentence of the Lease definition of 'Value of the Land' is not to introduce into the valuation process the restrictions on use contained in the Lease. Rather, its purpose and effect is to provide for a situation where a lawful existing use of the Property is a non-conforming use under current planning legislation. In the circumstances of the present case, that consideration was irrelevant in the valuation exercise."
15 On these grounds, his Honour concluded that the valuation conducted by Mr Gothard was in accordance with the Lease definition of "Value of the Land".
