36 In that respect, some assistance may be derived from the principles which are applied where a party resists inspection of relevant documents on the basis that they are confidential. In Mobil Oil Australia Pty Ltd & Anor v Guina Developments Pty Ltd & Anor[25], Hayne JA described the protection provided by the law, where a party is required to produce confidential documents, the inspection of which by trade rivals may have an irreparable adverse consequence to the party so providing production. In the present case, the plaintiff and the sixth defendant are not trade rivals as the parties who were before the Court in Mobil Oil. However, it is clear, on the materials before me, that they are very much "in competition" with each other, in respect of the right of the plaintiff to conduct forestry operations in parts of the Tasmanian wilderness. The first plaintiff seeks to assert and protect its lawful right to carry out those operations in those areas. On the other hand, the sixth defendant, the Wilderness Society, seeks to advance its lawful objectives of protecting the environment, raising public awareness in Australia of environmental issues, and planning, coordinating and supporting public campaigns opposing the harvesting of timber and the sale and export of wood chips. The affidavit of Mr Ogle, affirmed 30 June 2008, demonstrates vividly the competitive and adversarial public stances adopted by the two parties in respect of that issue. In my view, in an appropriate instance, the law would permit either party to withhold from inspection parts of documents discovered by them in this litigation, where it is appropriately established that those parts are both irrelevant to the proceeding and, if disclosed, would reveal to the other party confidential information, such as strategies, financing, organisation and the like, relating to the manner in which either party seeks to assert and maintain its public position in relation to the issue of forestry operations in the Tasmanian wilderness. Although I apprehended that in their written outline, counsel for the plaintiff sought to contend that the type of interest, which I have just described, would not be protected by law, in oral submissions Mr Waller did accept that if the redacted portions of the documents were both irrelevant, and related only to the broader strategies, financing structure, and the like, of the Wilderness Society, the sixth defendant would be entitled to redact those parts of the document, provided that, by so doing, the sixth defendant did not adversely affect or alter the meaning of the remaining portions of the document produced to the plaintiff on inspection. In my view, that position, taken by Mr Waller, is correct.
