12 The power of the Court to order costs is provided for in s 181 of the Act:
181 Costs
(1) Subject to the rules of the Commission and any other Act or law:
(a) the Commission may award costs, and
(b) costs are in the discretion of the Commission, and
(c) the Commission may determine by whom and to what extent costs are to be paid, and
(d) the Commission may order costs to be assessed on the basis set out in Division 11 of Part 3.2 of the Legal Profession Act 2004 or on any other basis.
13 Costs are also addressed in the Industrial Relations Commission Rules 1996. Particularly relevant are rr 211 and 216:
211 Costs of application or step within proceedings
Subject to this Part, the costs of any application or other step in any proceedings shall, unless the Commission otherwise orders, be deemed to be part of the costs of the cause of the party in whose favour the application or other step is determined and shall be paid and otherwise dealt with in accordance with the provisions of this Part.

216 Offer of compromise
(1) Upon the making of an order under Rule 168 (9), a party entitled to costs may, unless the Commission otherwise orders, have those costs assessed up to and including the day the offer was accepted.
(2) If a notice of offer contains a term which purports to negative or limit the entitlement to costs, that term shall, unless the Commission otherwise orders, be of no effect for any purpose under Part 23 or this Rule.
(3) Subrules (4)-(7) apply to an offer which has not been accepted at the time prescribed by Rule 168 (8).
(4) Where an offer is made by an applicant and not accepted by the respondent, and the applicant obtains an order on the claim to which the offer relates no less favourable than the terms of the offer, then, unless the Commission otherwise orders, the applicant shall be entitled to an order against the respondent for costs in respect of the claim from the day on which the offer was made, assessed on an indemnity basis in addition to costs incurred before and on that day, assessed on a party and party basis.
(5) For the purpose of subrule (4), where the offer was made on the first or a later day of the hearing of the proceedings, then, unless the Commission otherwise orders, the applicant shall be entitled to costs in respect of the claim from 11 am. on the day following the day on which the offer was made, assessed on an indemnity basis, in addition to costs incurred before that time, assessed on a party and party basis.
(6) Where an offer is made by a respondent and not accepted by the applicant, and the applicant obtains an order on the claim to which the offer relates not more favourable than the terms of the offer, then, unless the Commission otherwise orders, the applicant shall be entitled to an order against the respondent for costs in respect of the claim up to and including the day the offer was made, assessed on a party and party basis, and the respondent shall be entitled to an order against the applicant for costs in respect of the claim thereafter, assessed on a party and party basis.
(7) For the purpose of subrule (6), where the offer was made on the first or a later day of the hearing of the proceedings, then, unless the Commission otherwise orders, the applicant shall be entitled to costs in respect of the claim up to 11 am on the day following the day on which the offer was made, assessed on a party and party basis, and the respondent shall be entitled to costs in respect of the claim thereafter, assessed on a party and party basis.
Consideration
14 On 31 August 2007, after having made two reasonably significant Calderbank offers, neither of which could be regarded as designed merely to trigger costs sanctions, the respondents made a third offer in the form of an Offer of Compromise under the Commission's Rules: see Part 23. The Offer was $100,000 plus costs.
15 We consider this to be the critical offer by the respondents. We would not be prepared to adopt either of the earlier offers as the trigger for awarding costs to the respondent, as the first was made in circumstances where there was insufficient time for the appellants to properly consider the offer and where both the first and second offers were inclusive of costs. Although there is no rule that a Calderbank offer inclusive of costs is incapable of resulting in the court making an order for indemnity costs if the party to whom it is made fares worse at the trial (see Rockcote Enterprises Pty Ltd v FS Architects Pty Ltd (No.2); Carelli v FS Architects Pty Ltd (No.2) [2008] NSWCA 205 at [51]), we have reservations about whether the first two offers could be regarded as making sufficient allowance for costs.
16 The third offer, however, was at least double the respondents' previous offer of $60,000 inclusive of costs. The sum of $100,000 well exceeded a payment of three months' remuneration based on 250 cases per week, plus interest, without any discount for mitigation. The sum offered would have covered payment of Supervising Pathologist's fees, plus interest, in addition. This offer is to be viewed against the background of an original claim by the appellants in their summons for compensation of 12 months' remuneration ($795,000) in lieu of notice and their initial offer to settle of three months' remuneration ($170,000) plus costs. As the respondents submitted, given the high demand for pathologists in 2005 and the adequacy of three months' notice in the industry, there was also a substantial risk that any compensation awarded by the court would be based on three months' notice.
17 Because the first respondent in February 2005 had given three months' notice to the appellants, the effect of which was to give notice to terminate the appellants' existing contract and reduce the appellants' case load to 250 cases per week from about 23 May 2005, there was a substantial risk that the Court would find that any compensation for the period after the summary termination ought to be calculated on the basis of the reduced case load. Further, in view of the statutory requirement for the Court to consider mitigation (s 106(6)), there was also a real probability that the appellants' earnings from other sources would be deducted. We note that following the summary termination on 16 May 2005, the appellants earned $17,455 in the period from that date to the end of July 2005 after which time Dr Windrum took up full time employment with Mayne under a 30-month contract at the rate of $29,500 per month (exclusive of GST).
18 The appellants submitted that they should not be liable for the respondents' costs following rejection of the third offer by the respondents. It was submitted that the facts and circumstances of the case had characteristics and complexity that amounted to exceptional circumstances and should lead to a departure from the prima facie position set out in the relevant rule, in favour of the appellants.
19 It was contended that the complexity arose from the established relationship up to 24 February 2005, the unilateral change imposed on the appellants at that time, which was neither accepted nor expressly rejected by the appellants at the time of termination, and the arrangements put in place by the respondents in conjunction with the wrongful and unfair termination of the appellants in May 2005. It was submitted this was "far from the more normal termination scenario where the level of remuneration over any notice period is not in serious dispute".
20 The appellants noted that on the appeal, having found unfairness in the contract, the Full Bench determined that the appellants should be entitled to three months' notice or pay in lieu, which was reflected in a proposed order for 11 weeks' remuneration. That payment, it was submitted, could have been quantified in various ways ranging from $194,851 down to $38,251 (both including interest).
