The Court made clear that the conduct issues by themselves would not have been enough to justify a costs order. This is an important part of the reasoning. McElwaine J said that standing alone those matters would not have satisfied him that it was appropriate to exercise the discretion under section 570. The applicant had enjoyed very substantial success before Kerr J, the Full Court had not concluded that his claims lacked merit, and caution is required in Fair Work costs decisions so that parties are not discouraged from pursuing or defending claims under the Act.
What changed the position was the 6 April 2025 Calderbank offer, viewed together with the applicant's antecedent conduct. On 4 April 2025, the applicant made a written Calderbank offer seeking $30 million and a mutual deed of release containing mutual releases, non-disparagement obligations and confidentiality obligations. The respondents rejected that offer on 6 April 2025, describing it as completely divorced from the state of the evidence. They then made a counter-offer to resolve the proceeding by payment of $2.2 million inclusive of all costs, and said they would not pursue the applicant for costs, including in respect of identified unreasonable conduct relating to a late amendment. The offer was expressly made without prejudice as to costs and in accordance with Calderbank principles. It remained open until 10am on 7 April 2025. There was no reply.
The Court said a failure to accept a Calderbank offer may amount to an unreasonable act or omission for the purposes of section 570. The question is objective and must be assessed in the circumstances as they were then known. The judge treated the timing of the offer as especially important. It was made well after the applicant's cross-examination had concluded and after the end-of-year holiday period and Court vacation. The trial had sat until 23 October 2024, then adjourned to resume on 31 March 2025. The applicant therefore had a considerable period to reflect with his legal advisers on the progress of the case before the offer arrived.
McElwaine J said it was objectively correct for the respondents' solicitor to characterise the applicant's cross-examination as disastrous, referring to the primary reasons and especially the passages dealing with credibility. The applicant had been repeatedly challenged that his evidence was false, implausible, made up and otherwise unsatisfactory. The judge said it was manifestly clear to any observer that adverse credibility findings were highly likely. Acting reasonably, the applicant and his legal representatives should have reflected very carefully on the prospects of succeeding on the multiple claims well before receiving the 6 April 2025 offer.
The Court accepted that the respondents' primary witnesses on the adverse action issues had not yet entered the witness box, but said that did not answer the point. The applicant already had all of their affidavit evidence. The offer was made at a time when the inherent weakness of the applicant's claims was objectively clear. The judge said that, acting reasonably on what was then known, the applicant should have concluded that his prospects were dim on the termination and non-termination adverse action claims and the discrimination claims, which formed the bulk of the proceeding. That effectively left the contract claim, with a best-case quantum significantly less than the offer.
The Court also rejected an argument that the applicant could assess the offer by reference to what he might have achieved if all his contentions were accepted. The proper question was whether a more beneficial result was realistically possible. McElwaine J held that, acting reasonably at the time of the offer, the applicant ought to have understood that a better result was not a realistic possibility.
As to the short deadline, the Court held it was not unreasonable in the circumstances. The trial was continuing, the applicant had already reflected on his case before making his own 4 April 2025 offer, and he had the benefit of 6 April 2025 as a non-sitting day to consider the respondents' offer before the hearing resumed on 7 April 2025.
The extent of the compromise also mattered. The judgment records a history of offers, including a respondents' offer of $2.6 million in February 2022 and the later $2.2 million offer on 6 April 2025. Evidence from the respondents was that the lower figure reflected significant legal costs already incurred, the fact that the retrial had already proceeded for 22 days, and their assessment that the applicant's prospects had reduced. The Court held that the applicant, with legal representation, ought reasonably to have understood that the respondents had incurred significant legal costs since 2022 and that the offer reflected a genuine attempt at compromise on commercial terms that favoured the applicant at that time.
