3 Neither contention has any merit. As to the first point, the respondent knew, from the description of document 114, that it referred to the total annual revenue figures for all Civic stores in Western Australia. The whereabouts of Civic stores in Western Australia is not confidential information and it is to be inferred that the locations of the stores could be ascertained without looking at a document which contained the revenue figures from those stores. As to the second point, the master's findings at [15] and [16] of the master's reasons addressed documents 112 and 113 respectively, and not document 114. As to [21] of the master's reasons, the master did not find, contrary to the effect of the respondent's contention in par 1.2 of his submissions of 23 April 2013, that the commercial sensitivity of the revenue information in document 114 diminished over time. Moreover, [21] of the master's reasons must be read in the context of the reasons as a whole. Although the first sentence of [21] of the master's reasons refers to the three documents in question, when read with the second sentence, in light of the master's findings at [18], the effect of [21] is that the commercial risks to the appellant resulting from disclosure to Mr Paterson, a trade rival, were outweighed by the prejudice to Mr Paterson if he did not see the document. This court found that that was a balancing exercise which could not be undertaken without ascertaining, by reference to the respondent's evidence, the precise prejudice to Mr Paterson if he did not personally see the document (see [67] of the principal reasons). If the respondent wished to contend that all of the information in document 114, or some of it (and if the latter, he would need to specify which) was not commercially sensitive, and that the master was wrong when he found, at [18], that it was 'not difficult to see how the commercial position of the [appellant] could be undermined', these contentions required a notice of contention. For these reasons, the respondent's application should be dismissed.
