The same day, Mr Catsanos wrote to Ms Benk, as litigation service manager of the first defendant, a letter which included the following:
"I confirm that following ongoing negotiations with Ms Gergis on behalf of the Applicant, the matter was settled on 19 April last [either there is an error in this date or the final telephone negotiations were on 19th, not 21st] for a total of $40,000.
The basis of that settlement is that it will be a full determination of all rights to compensation.
I made it clear that settlement would be on the basis of lump sum compensation with awards in favour of the Respondent in respect of weekly compensation and s60 expenses, amendment of the Application to cover all possible injuries together with Admissions, Agreed Facts and a Deed of Release.
In those circumstances then I am returning your file and confirm that you will be forwarding the settlement documentation to the Applicant's solicitors."
11 Mr Catsanos also sent his memo of fees on the basis the settlement had been concluded, charging fees for "Agreeing Terms of Settlement with the Claimant".
12 On 23 April 2004 Ms Benk wrote a letter to the plaintiff's solicitor which, omitting formal parts, read:
"We refer to the above matter.
We enclose the following documents to be duly executed by yourselves [ sic ] and returned to our office at an early date [it will be observed no deadline was specified] to GPO Box 4085 Sydney, so we can attend to filing of the same:-
1. Agreement to Discontinue Proceedings
2. Application for Registration of Agreement
3. Agreed Facts and Admissions
4. Deed of Release
5. HIC Notice of Judgment or Settlement.
Should you wish to discuss this matter further please do not hesitate to contact our office."
13 The evidence in this case included affidavits from three experienced worker's compensation practitioners. Whether or not the documents referred to in Ms Benk's letter could be described with semantic accuracy as "standard", it is clear on the evidence that there was nothing remarkable about them. They were in a common form and the letter did not refer to them as drafts to be settled, but as "documents to be duly executed". In fact, they were treated that way and returned signed in due course.
14 However, before that happened, certain events intervened which gave rise to the present dispute.
15 The first event was but a straw in the wind. Ms Benk attended the first defendant's premises on the holiday Monday, 26 April, of the Anzac Day weekend. She decided to send a further letter, dated 26 April 2004, to the plaintiff's solicitor in the following terms, omitting formal parts:
"We refer to the settlement negotiations in this matter and note the Applicant has agreed to accept our offer of compensation in the total sum of $40,000.00.
Please be advised that this is contingent upon Admissions, agreed facts, Findings, Common Law Release and Awards for the Respondent being entered with an interpreters [ sic ] certificate.
These documents must be returned to our office prior to the issue of any binding medical assessment certificate. Failure to do so will cause the offer to be withdrawn.
On 23 April 2004 we forwarded to your office the 'settlement pack'. We omitted to enclose the HIC documentation, which was noted in that document.
Please ensure that these documents are forwarded to this office within 7 days."
16 This letter calls for a number of comments. In the first place, it confirms the evidence of the plaintiff's solicitor that the documents were actually "standard", at least standard for the large insurer which is the first defendant. The expression in inverted commas "settlement pack" could only indicate that. In fact, in cross-examination, Ms Benk referred to "a number of settlement packets [that] were generated" on the one day, evidencing the widespread extent of their use. If they were standard for that insurer, it is difficult to see why Mr Catsanos's reference to them did not have the quality of certainty as a reference to its standard "settlement pack", "the 'settlement pack'" as its solicitor called them, using the definite article.
17 Secondly, the letter expressly acknowledges "the Applicant has agreed to accept our offer", but then purports to add a condition which had never before been suggested and was certainly not part of the "offer". This condition is expressed to require the return of documents "prior to the issue of any binding medical assessment certificate", a condition the failure of which, it is stated, "will cause the offer to be withdrawn". As to this, it is plain law that an offer, once accepted, cannot be withdrawn.
18 Thirdly, I accept the evidence of the plaintiff's solicitor that she never received this letter. On all the evidence, I think it is more probable than not that the reason for its not being received was not an error in the post, but a failure to post it. No one gave evidence of actually posting it; it was intended to be sent under circumstances differing from the ordinary course, namely, on a holiday; and when the first defendant's solicitor herself compiled what she described as "[t]he chronology in this matter" at a time close to the events, she omitted this letter altogether. It would be a surprising coincidence if the letter was sent, despite these circumstances, but was the only letter passing between the parties to be lost in the post or otherwise misdelivered.
19 I described the letter as only a straw in the wind because, at the time it was written, the evidence does not suggest the condition sought to be included after the contract had already been made was likely to have any importance. But on the very next day, 27 April 2004, the Commission gave notice of a Medical Assessment Certificate of Dr Breit which would, in fact, become binding, if the settlement were avoided, upon the issue, after the expiration of 28 days, of a Certificate of Determination.
20 After receipt of the Medical Assessment Certificate, Ms Benk wrote on 13 May 2004 a letter which, omitting formal parts, stated the following:
"We are in receipt of new binding [emphasis original] medical evidence of Dr Briet [ sic ] dated 27 April 2004.
Consequently, we are instructed to retract our settlement offer."
21 It was five days later that the first defendant's solicitor received the relevant documents signed by the plaintiff. In a letter dated 22 June 2004, which contained the "chronology" I have referred to, Ms Benk wrote to the plaintiff's solicitor (inter alia):
"We have not failed to honour our agreement. The agreement was retracted prior to your client forwarding to us the endorsed settlement documents.
The agreement was contingent upon all documents forwarded to you on the 23 April 2004 being endorsed and signed by both the Applicant and his interpreter."
22 It will be noted that the contingency alleged in this latter was the return of the documents "prior to the issue of any binding medical assessment certificate", the contingency attempted to be imposed on 26 April, and that the documents were in fact returned before the certificate became binding by the issue of a Certificate of Determination. Nor does the letter explain how "[t]he agreement" the existence of which it admits could be "retracted". What can be retracted is an offer that has not yet been accepted so as to become an agreement.
23 It is in this situation, the plaintiff having commenced proceedings in the Supreme Court to enforce the settlement, that the defendants raise in defence, not the futile pretext that they could avoid honouring their promise by retracting their accepted offer, but that the terms of the offer made on their behalf, in accordance with a very wide practice in the worker's compensation field, were incomplete or so uncertain as to be incapable of constituting a contract upon acceptance, or even that an intention to be bound by terms offered in this form could not be found.
24 Counsel for the defendants expressly disavowed any contention that, if an agreement was intended and was sufficiently expressed to be complete and not uncertain, it could nevertheless be held void. He said, "I cannot suggest it is void". He did not argue that the provision, which has been in every Worker's Compensation Act for many years, preventing contracting out, should be construed as invalidating an agreement to settle a proceeding brought under the terms of the relevant Act.
25 Under the heading "Uncertainty and Incompleteness", the learned authors of Carter and Harland, Contract Law in Australia, (4th ed, 2002) at sec 258, state the relevant principles:
"Two related, but conceptually distinct, principles are here involved. In the first place, the language used by the parties may be such that the court is unable to attribute to it a sufficiently precise and clear meaning in order to identify the scope of the rights and obligations agreed to. In such a case there is in fact no concluded agreement and the alleged contract will be held to be void for uncertainty. Second, even though the language used is perfectly clear in its meaning, if some important part of the transaction is yet to be agreed upon there is, despite appearances, in truth no completed agreement and the alleged contract will fail for incompleteness. In any given case there may in fact be elements both of uncertainty and incompleteness."
26 But in sec 260 et seq, they make it clear that the Court should strive to give effect to commercial arrangements:
It has frequently been said that the courts will interpret the language used broadly and fairly (especially when approaching a document drafted by laypersons) and that it is their duty to place a reasonable meaning on that language unless this is 'utterly impossible'. While it may be questioned whether the courts do in fact always avoid the temptation 'to repose on the easy pillow of saying that the whole is void for uncertainty' (alternatively described by Goff LJ as 'a counsel of despair'), the prevailing approach is one of upholding agreements wherever possible. Difficulty of interpretation must be distinguished from absence of meaning."
