(2) If an option is void under this section, section 66ZE applies as if an effective notice of rescission of the option had been served under this Division, except that:
(a) the purchaser is not liable to the forfeiture provided for under that section, and
(b) that section has effect as if it provided that the whole of the consideration paid in relation to the option and the whole of any deposit paid in relation to the purchase of the property are payable to the purchaser."
15 Having regard to s 66ZG(2), it is pertinent to quote s 66ZE:
"(1) On service of an effective notice of rescission in accordance with section 66ZD in relation to an option to purchase residential property, the option is to be taken to be rescinded ab initio, but subject to the rights and obligations conferred by this section.
(2) The purchaser forfeits 0.25 per cent of the purchase price of the property to the vendor.
(3) The amount forfeited may be recovered from any consideration paid in relation to the option or from any deposit paid in relation to the purchase of the property.
(4) If the consideration or deposit is insufficient, the balance of any amount forfeited may be recovered from the purchaser as a debt in any court of competent jurisdiction.
(5) The balance of the consideration or deposit remaining after deduction of any amount forfeited is payable to the purchaser.
(6) Subject to subsection (7), neither the vendor nor the purchaser is liable to pay any other sum for damages, costs or expenses.
(7) Either party is entitled to make a claim for:
(a) such compensation, adjustment or accounting as is just and equitable between the vendor and purchaser where the purchaser has received the benefit of possession of the property, or
(b) the payment of damages, costs or expenses arising out of a breach of any term, condition or warranty contained or implied in the option,
but not so as to affect rights and obligations arising under this Division.
(8) The vendor may agree to waive any rights regarding forfeiture under this section.
(9) Stamp duty ceases to be payable on an option rescinded under this Division, and the provisions of the Stamp Duties Act 1920 relating to the refund of any stamp duty paid on a rescinded agreement for the sale of property apply in relation to any stamp duty already paid on the rescinded option.
(10) In this section, "deposit" includes any amount paid by the purchaser in relation to the proposed contract attached to the option or on account of the purchase price of residential property."
16 There is, on the pleadings, an issue whether the strata lot the subject of each of the deeds is "residential property" within the statutory definition applying for the purposes of s66ZG. The Purchaser, as plaintiff, alleges in the statement of claim that the subject matter of each deed is "residential property", but the Vendor, in its defence, does not admit this. However, Mr Tregenza of counsel, who appeared for the Vendor upon the hearing of the separate question, conceded in court this morning that each lot is "residential property". I proceed on that basis.
17 That being so, there can be no doubt that the Call Option created by clause 2 of each deed is affected by s 66ZG. The Call Option is, clearly enough, what s 66ZG(1) calls "an option granted for the purchase of" the particular residential property to which the deed relates. On the footing that, as a matter of construction, the period "commencing after the date of this deed" commenced immediately upon the expiration of the day of the date that the deed bears (that date being either 1 or 2 September 2008), the option became exercisable at the commencement of the next succeeding day (that is, 2 or 3 September 2008) and remained exercisable until 12 noon on 28 November 2008. The period within which the option was capable of being exercised was therefore a period of 87 or 86 full days (plus part of 28 November 2008), and that period included the 42 days after the option was granted.
18 Having regard to the defendant's concession, each Call Option is thus of the description in s 66ZG(1)(b). Section s 66ZG(1) therefore makes it "void", with the consequences stated in s 66ZG(2).
19 That brings to the fore the second aspect of the separate question - in essence, whether, as a consequence of the operation of the statutory provisions on the Call Option, the Put Option is also "void". I am of the opinion that, essentially for reasons advanced by Mr Tregenza in his submissions on behalf of the Vendor, that question must be answered in the negative.
20 It is clear that s 66ZG(1) does not, of its own force, affect the Put Option which is not, on any view, an "option granted for the purchase of" the relevant strata lot. The question is really whether, although both were created by the same deed, the Put Option stands apart from the Call Option in such a way as to be insulated from the statutory avoidance affecting it or whether, in truth, it is caught up by that statutory avoidance.
21 Before attention is given to legal principles about "severance", it is appropriate to say something about the purpose behind s 66ZG(1)(b). The provision was introduced by the Conveyancing (Sale of Land) Amendment Act 1990. The Minister for Natural Resources said in his second reading speech in the Legislative Assembly on 21 November 1989 (Hansard, page 12923):
"The existing ban on short-term options has been retained and extended to cover options exercisable within 42 days of the grant. This extension is necessary to allow grantees and their solicitors sufficient time to obtain the necessary searches and certificates to test the vendor warranties contained in the option."
22 The legislative preoccupation was therefore with the possibility that grantees of options to purchase - that is, potential purchasers - would not have time to complete necessary investigations before having to decide whether or not to exercise the option, with the result that they might come under pressure to exercise the option (rather than lose the property) before having been able to obtain the assurance and protection that the investigations provide. This may properly be borne in mind as the question of severability is approached.
23 Courts have, in different cases, taken different approaches to the question whether part of a contract can be separated form the remainder and discarded, leaving that remainder intact. Mr Tregenza handed up and relied on paras 877 to 879 of "Halsbury's Laws of England", fourth edition reissue, Volume 9(1), in which the matter is discussed.
24 Some of the approaches taken by courts were referred to by the Privy Council in Amoco Australia Pty Ltd v Rocca Bros Motor Engineering Pty Ltd (No 2) (1975) 133 CLR 331 at 342:
"As Kitto J remarked in Brooks v Burns Philp Trustee Co. Ltd . (1969) 121 CLR 432 at p 438, 'questions of severability are often difficult'. The answer depends on the intention of the parties as disclosed by the agreement into which they have entered; but generally, of course, they have not foreseen that one or more of the provisions in their agreement will be unenforceable. Various tests have been formulated which might not in every case lead to the same result -- e.g. is that which is unenforceable 'part of the main purport and substance' of the clause in which it appears? (per Lord Moulton in Mason's Case : sub nom Mason v Provident Clothing and Supply Co Ltd [1913] AC 724 at p 745); does the deletion "alter entirely the scope and intention of the agreement?" (per Lord Sterndale MR in Attwood v Lamont [1920] 3 KB 571 at p 580); does the deletion of the covenant in question "leave the rest of the deed a reasonable arrangement between the parties" (per Denning LJ in Bennett v Bennett [1952] 1 KB 249 at p 261); does what is left constitute an "intelligible economic transaction in itself ... even though it furnished the occasion for" the unenforceable restraint? ( Kelly v Kosuga (1959) 358 US 516 at p 521)."
25 The question in that case concerned the severability of a provision that was void because it imposed an unreasonable restraint on trade. Here, by contrast, the court must judge the impact of a statutory regime that makes a particular kind of contract "void" (but not, it must be noted, illegal) and goes on to prescribe for the parties rights and obligations not only different from those created by the "void" contract but also apparently different from those that would exist if the contract were a nullity. Examination of the precise scope and operation of that statutory regime is therefore necessary.
26 Section 66ZG(1) makes "void", in the sense explained in s 66ZG(2), "an option granted for the purchase of" relevant property. The provision thus operates upon (and only upon) contractual provisions under which a prospective purchaser can compel a prospective vendor to sell, with the compulsion arising, by force of those provisions, from the unilateral choice of the prospective purchaser in the form of exercise of the contractual right to bring into existence a contact under which both are bound to a transaction of sale and purchase.
