By s 280(1) of the Act, a party's recoverable costs are confined, in effect, by the scale limits. To that extent, s 280(1) is protective of the party charged and, more generally, serves the due administration of justice by limiting the allowable scope for legal costs. Section 280(2) operates as an exception to s 280(1) of the Act. Section 280(2) of the Act operates to give the successful party the opportunity to recover those costs which have been reasonably and properly incurred where, in the court's opinion, the scale is inadequate because of the unusual difficulty, complexity or importance of the matter. To that extent, s 280(2) of the Act is protective of the successful party to the litigation and, on that account, also serves the administration of justice by facilitating, within the limits imposed by the statutory criteria, the operation of the general principle that a successful party is entitled to its costs of the litigation. Even where orders are made under s 280(2) of the Act, it nevertheless remains the task of the taxing officer to consider the reasonableness of and necessity for the work undertaken, and to make a judgment about the remuneration reasonably required.
Before such a power will be exercised, the court must form an opinion that has two components. First, the court must form the view that the maximum amount allowable under the relevant scale item is inadequate in the sense that there is a fairly arguable case that the bill to be presented to the taxing officer may properly tax at an amount which is greater than the limit which would be imposed by the relevant cost determination. Secondly, the court must also form the opinion that the inadequacy of the costs allowable under a costs determination arises because of the 'unusual difficulty, complexity or importance of the matter'. Issues of the kind which arise are addressed as matters of impression, rather than as matters of detailed evaluation, precision or science.
For the purposes of exercising the powers conferred by s 280(2) of the Act, it will not ordinarily be necessary for the court to determine what amount should be allowed on taxation, but only whether there is a fairly arguable case that a greater amount should be allowed than that which is allowable under the relevant determination: Electricity Generation and Retail Corporation trading as Synergy v Woodside Energy Ltd.
A fairly arguable case to that effect will not be established merely because a party incurred greater costs than those allowable under the relevant determination. However, depending on the particular case and all the circumstances, the fact that a party has applied significantly greater legal resources to each step in the litigation than those for which allowance is made under items of the relevant determinations, when viewed in the context of the difficulty, complexity or importance of the matter, may sustain the conclusion that there is a fairly arguable case that each of the items identified is inadequate (and thereby the amount of costs allowable in respect of the matter is inadequate) because of the unusual difficulty, complexity or importance of the matter.
The word 'unusual' in s 280(2) of the Act qualifies only the 'difficulty' of the matter, and not its 'complexity' or 'importance'. The word 'unusual' in this context means unusual having regard to what one might describe as the usual run of civil cases determined in the court. That essentially involves the making of a value judgment by the court, having regard to the court's experience of the particular case when compared with the usual run of cases: Wainwright v Barrick Gold of Australia Limited. Also, the reference to 'importance' in this context allows the court to have regard to the significance of the issues that arose in the litigation. Significance can arise either because of the significance of the issues to the parties, or because of the significance of the issues to other prospective parties, or to the public or community generally: Heartlink Ltd v Jones as liquidator of HL Diagnostics Pty Ltd (in liq).
In Kidd v The State of Western Australia, this court observed, with reference to Electricity Generation, that the question of unusual difficulty, complexity or importance arises in respect of the proceedings as a whole and not in respect of each individual item in the relevant costs determination. In Electricity Generation, Martin CJ observed:
