27 On such a taxation, the Taxing Officer will often be able to proceed by way of analogy, utilising as a guide, at least for the most part, one or more determinations or scales applicable in the jurisdiction to work which is substantially similar in nature and responsibility to the business which is the subject of the bill. In the present case, for example, the determination applicable to appeals to the Full Court may well prove a helpful guide, although it will no doubt require some adaptation and in respect of some items another determination or scale, such as that applicable to non-appellate business in this Court, may well prove useful. In respect of business or items for which there is no adequately comparable determination or scale in this jurisdiction, it will prove necessary for the Taxing Officer to draw more generally on his or her knowledge and experience of the remuneration of practitioners in this State to determine what level of charging is reasonable in the circumstances. This process necessarily involves regard, in particular, to the nature of the business undertaken, the degree of skill, responsibility, complexity and urgency which it requires, and which was given to it, as well as the time required to perform it. In some situations a Taxing Officer may even gain some assistance from the Solicitors' Costs Determination 1998 even though it is not intended to apply to contentious business. Contrary to one submission for the firm before the learned Taxing Officer, it would not be necessary or appropriate for a Taxing Officer to have regard to the charges provided or allowed for work in other State jurisdictions.
