McHugh J assumed but to my reading should not be understood to have decided that the benefit and burden principle extends to persons who are not parties to or named in the Deed (at 648). The benefit and burden principle was extensively criticised in Government Insurance Office (NSW) v KA Reed Services Pty Ltd [1988] VR 829 by Brooking J in his judgment at 830 to 841: the views of Brooking J would have to be addressed carefully by a court which is asked to act simply on that principle, but that is not the present case. The principle of benefit and burden has not become established as a general legal principle. It has sometimes been referred to as the Ocean Island Equity, an allusion to Tito v Waddell (No 2) [1977] Ch 106. It was considered with references to authorities and sources, by Young J in Rural and Agricultural Management Ltd v West Merchant Bank Ltd (1995) 18 ACSR 793 and in Ryan v Rouen [2000] NSWSC 468 at [72] to [75]. There seems to be room for such a principle where owners of equitable interests or claimants against a fund compete with other similar claims. In context of positive obligations under easements Rhone v Stephens appears to have concluded against any such principle."
28 The benefit and burden principle is not certain. With the consent of Mr Love, Mr Prior caused $47,454.15 worth of work to be carried out on the premises so that it complied with the development application for the use of the premises. Mr Prior has obtained a valuation of the property and has offered to buy the property for a figure higher than the valuation but the Bank had refused to negotiate. There is an arguable case that the Bank has taken a benefit, namely an increased value of the premises and does not want take the burden, namely consenting to the option.
29 State Wide further submitted that the consent to the renewal of the lease cannot be unreasonably withheld. State Wide referred to a passage from The Law of Consent, by Young JA, (1986) The Law Book Company, where his Honour stated (at 156):
"The landlord is not bound to give any reasons for refusing his consent, Young v Ashley Gardens Properties Ltd [1903] 2 Ch 12; Goldstein v Sanders [1915] 1 Ch 549, but if he does not, the court would more readily imply that the withholding was unreasonable, Frederick Berry Ltd v Royal Bank of Scotland [1949] 1 KB 619 at 623, explaining a dictum of Slesser LJ in Lambert v F W Woolworths & Co (No 2) [1938] Ch 883 at 906. However, the facts may be so plain that no reasons need to be given, such as in Goldstein v Sanders , where the tenant had so conducted himself as to make the landlord's refusal perfectly reasonable."
30 This passage refers to the landlord/tenant relationship but not one where the mortgagee takes possession. However, this proposition is at least arguable.
(iii) Unconscionable conduct
"13.1 Alternatively, and only in the event the contentions of the cross claimant in paras [11.1] - [12] above are not upheld, the Second Defendant pleads as follows:
(a) the current market value of the Land is $650,000.00;
(b) The Plaintiff has not commenced any marketing campaign in respect of the Land;
(c) a marketing realisation period in respect of the Land would be 9-12 months;
(d) the amount owing by the First Defendant to the Plaintiff exceeds $1M;
(e) The Second Defendant had substantial moneys invested in the Land from which its business is being conducted;
(f) there are no other business premises reasonably available to the Second Defendant;
(g) The Plaintiff has served its Notice seeking vacant possession as a tactic to extract from the Second Defendant the amount owing from the First Defendant;
(h) the insistence by the Plaintiff on its strict legal rights to vacant possession is harsh, oppressive or capricious.
13.2 In all circumstances the conduct of the Plaintiff seeking vacant possession of the Land constitutes unconscionable conduct within the meaning of Section 51AA of the Trade Practices Act 1974 (Cth).
