15 However, while this case bears some similarity to Corbett, there are important differences, including that in Corbett there were five defendants as opposed to two and what were described as "contentious" liability and contribution issues. While it is true that those matters were in issue during this trial, I would not categorise the issue of liability against Impact as particularly contentious, at least as the evidence unfolded before me. I think its negligence was gross.
16 It must have been apparent to parliament that s151 M contemplated situations where liability was in issue and other parties were involved. Nevertheless, it did not stipulate that the offer of settlement must resolve all issues between all parties. In this case, in my view, there may have been considerable utilitarian value in a settlement between Mr Goodman and Impact.
17 In my opinion, Mr Goodman has established an entitlement to interest in accordance with s151 M.
18 Mr Torrington did not submit otherwise than that his client is liable to pay interest.
19 So far as Impact is concerned, interest is to be calculated upon past economic loss due to loss of earnings. The relevant components total $283,813. From this sum before calculation of interest $122,156 must be deducted being the total of the Workers Compensation payments made to date viz $135,763 less "Fox v Wood" tax deducted of $13,607. This produces the sum of $161,657 upon which Mr Goodman is entitled to interest. The parties agreed that as against Impact, an appropriate interest rate would be 6.75% per annum; that the period is 5.66 years and that the product of that calculation should be divided by 2 to spread it over the period. The sum thus derived is $30,880, which I will allow as against Impact.
20 Against Inasmuch, the interest payable is regulated by s18 of the Civil Liability Act. Effectively, the interest is to be calculated upon the same sum as interest is calculated against Impact, viz $161,657. The parties agreed that 6% per annum would be appropriate. On this basis, I calculate interest at $27,449.
21 There remains the questions of costs. Both defendants concede that orders should be made against them. They contend, however, that each should only be ordered to pay 50% of the costs, reflecting my apportionment of liability. Although I adopted a similar procedure in Chubs Construction Pty Ltd v Chamma [2008] NSWSC 382 there was a particular reason for doing so in that case.
22 Mr Stone submitted that as a matter of well established principle the order should simply be that the defendants pay the Plaintiff's costs. He referred to G E Dal Pont Law of Costs (second edition) at page 309 and authority, including Michel v Bullen (1818) 146 ER 749 and the more recent decision of Gzell J in Rushcutters Bay Smash Repairs Pty Ltd v H McKenna Net Makers Pty Ltd [2003] NSWSC 670.
23 It seems to me that the principle is correctly identified in Mr Stone's submission and that there is no reason in this case to modify it. Both defendants should be held jointly and severally liable for the costs of the proceedings on a party and party basis. The authority for such an order against Impact is contained in clause 89 of the Workers Compensation Regulation as Impact's final offer of settlement as certified by the mediator was "award for the Defendant each party to pay own costs". In any event, as I have indicated, Mr Catsanos did not oppose the making of a costs order against his client.
24 In summary, therefore, I assess damages against Impact as follows:
