THE DEFENDANT'S POSITION
17Mrs Coshott does not dispute the quantum of interest claimed in the period from November 2003 to October 2008 of $24,132.52. However, she asserts two reasons why this amount is not payable. Both of her arguments depend on s 190 of the Legal Profession Act 1987 which provided:
"190 Interest on outstanding costs
(1) A barrister or solicitor may charge interest on the unpaid costs for legal services provided by the barrister or solicitor, if the costs are unpaid 30 days or more after the barrister or solicitor has given a bill of costs for those services in accordance with this Division.
(2) A barrister or solicitor may not charge interest on the unpaid costs for legal services unless the bill of costs for those services contains a statement that interest is payable and of the rate of interest.
(3) A barrister or solicitor may also charge interest on the unpaid costs for legal services in accordance with a costs agreement.
(4) A barrister or solicitor may not charge interest under this section or under a costs agreement at a rate that exceeds:
(a) except as provided by paragraph (b)-the rate prescribed under the Supreme Court Act 1970 in respect of unpaid judgments of the Supreme Court, or
(b) the rate prescribed by the regulations."
18It is common ground that there was no provision in the costs agreement for interest on unpaid costs. It was also common ground that Mr Barry and Mr Board made the claim for interest under s 190(1) subject to the terms of s 190(2), rather than a claim under s 190(3).
19The first argument of Mrs Coshott is that s 190(1) can only be relied upon if there was a provision for interest in the costs agreement. The written submissions dealing with this were in the following terms:
"Section 190(1) of the LPA does not enable a legal practitioner to charge interest for costs in the absence of a contract for the payment of legal services, such as a costs agreement. Rather, it enables enforcement of provision for interest in such an agreement where those costs have been unpaid for 30 days."
20In the course of submissions Mrs Coshott accepted that interest for costs could be awarded in the absence of a valid costs agreement. Oliveri v P M Sulcs and Associates Pty Ltd (in liq) [2013] NSWCA 84 appears to support such an entitlement.
21In Oliveri, Mr Oliveri's only entitlement to fees was on a quantum meruit basis because there was no binding costs agreement (see Oliveri at [3]). Mr Oliveri failed in his claim for interest, not because of the absence of a costs agreement but because the provisions of s 190(2) were not satisfied. The reference to interest in the invalid costs agreement could not be regarded as part of the bill of costs as it was not to be regarded as part of a "combined identity" and it did not "complement the bill of costs or constitute it": see Oliveri at [21]. Further, even if the invalid costs agreement were to be regarded as part of the bill of costs the provisions relating to interest did not satisfy the terms of s 190(2): see Oliveri at [22], [23].
22Thus, Mrs Coshott's argument became not that there needed to be an interest provision in a costs agreement but if there were a costs agreement it would need to have an interest provision in it to found an entitlement under s 190(1).
23In my view, such a complicated implication in the legislation was unsupported by any principle, policy, or precedent. It is contradicted in the Oliveri decision. The text of s 190 gives no support for the implication. The arrangement of s 190, with s 190(3) following subsections (1) and (2) and providing that a legal practitioner "may also charge interest...in accordance with a costs agreement", indicates clearly that s 190(3) provides an alternative basis for a claim for interest. Section 190(4), which provides for interest being charged "under this section or under a costs agreement", reinforces this construction.
24But, of course, the strongest textual feature is the absence of any reference in either s 190(1) or (2) to the need for a provision for interest in the costs agreement. Indeed, there is no reference to a costs agreement in those provisions at all. In my view, to include a requirement in addition to the express matters mentioned in s 190(1) and (2) that the legal practitioner must also satisfy a further matter - a provision for interest in a costs agreement, if a valid costs agreement exists (see Oliveri) - is to re-write the legislation, not to construe it. This is especially so when the provision for interest in a costs agreement is expressly mentioned as an alternative in the following subsection (3): expressio unius est exclusio alterius.
25This conclusion is also supported by Gzell J in the Oliveri matter at first instance ([2012] NSWSC 1198 at [19]), the decision upheld by the Court of Appeal, and the recognition in the later provision of s 208E(2) of the Act of the alternative claims for interest under the Act and under a costs agreement.
26For these reasons, I do not accept that there was any implied requirement under s 190(1) that a legal practitioner's entitlement to interest requires a provision for interest in a costs agreement, or alternatively (and even more unlikely) requires a provision for interest in a costs agreement if a costs agreement exists. In my view, the argument is devoid of any legal merit.
27The second argument advanced by Mrs Coshott, not in written submissions but orally, against the claim for interest is that there was no provision for interest in the bill of costs. As is plain from s 190(2), proof of such a provision is necessary for a claim under s 190(1). The bill of costs was in evidence headed, "BILL OF COSTS", on p 1 of the bill. At paragraph 3 it stated, "Pursuant to Section 190 of the Act the solicitor intends to claim interest at the rates prescribed under section 95 of the Supreme Court Act 1970." It is apparent that the bill was prepared with one eye on the requirements of reg 45 of the Legal Profession Regulation 2002 which, pursuant to s 190(3) of the Act, sets out the particulars to be included in a bill of costs. The items in the bill of costs deal with these paragraphs in reg 45(1) in the same order as they appear in the sub-regulation.
28Mrs Coshott relied upon [21] of Oliveri which is mentioned above and which stated in respect of the costs agreement, relevantly, "[it] did not form a combined identity and [it] did not complement the bill of costs or constitute it." I do not see this passage as offering any assistance to Mrs Coshott. Even if I regarded the first two pages of the bill of costs as separate from the itemised part, it is clear that the two sections did form a "combined identity" in accordance with the passage in Oliveri at [22].
29I note that the first two pages of the document headed "BILL OF COSTS" refer to "Attached is an itemised Bill of Costs" and "the attached Bill of Costs." These phrases were not referred to by Mrs Coshott as indicating that the first two pages were not part of the bill of costs and, in any event, in my opinion they are insufficient to take the claim for interest made on the first page of the document to be outside of, and separate from, the bill of costs so as to leave s 190(2) unsatisfied.
30No argument is made by Mrs Coshott about the wording in the bill of costs. It included, as I have quoted earlier, "3. Pursuant to Section 190 of the Act the solicitor intends to claim interest at the rates prescribed". That raises the question of whether this is a "statement, speaking at the date of the bill and in accordance with s 190(2), that 'interest is payable' in respect of the bill" (see Oliveri at [22]). However, both for the reason that the matter was not raised by Mrs Coshott and, in any event, because of the express reference to s 190 in paragraph 3, I am persuaded that the requirement of s 190(2) is satisfied by these terms in paragraph 3. The circumstances were different in Oliveri where the relevant statement was contained in a document of a different date and thus, was not "speaking at the date of the bill" (see Oliveri at [22]).
31Mr Barry and Mr Board also raised the matter of a res judicata, that the question of interest being payable has been determined by the costs assessor in the certificate and therefore cannot be re-litigated by Mrs Coshott in these proceedings.
32The terms of the certificate are set out earlier in this judgment. Reference was made to CSR Timber Products Pty Ltd v Weathertex Pty Ltd (2013) 83 NSWLR 433 at [14] and [15], to Kuligowski v Metrobus (2004) 220 CLR 363, and to Papua New Guinea, Administration of the Territory of v Daera Guba (1973) 130 CLR 353 at 453 to establish the proposition that the doctrine of issue estoppel extends to any tribunal giving a final decision on a matter even if it is not a court. In view of my earlier findings, I do not need to finally determine this point, although I am satisfied that Mrs Coshott is bound by the finding of the assessor in respect of interest being payable and the rate.
