26 Inspector Buggy's field of specialised knowledge is the general principles of risk management and risk assessment. He has no specialised knowledge or practical experience as to the proper application of the general principles of risk management and risk assessment in the mining industry either as applicable in 2003 or, I would conclude, in 1996. It is against that background and having regard to my earlier comments and conclusions that I deal with the admissibility or otherwise of those passages in Inspector Buggy's statement that are the subject of objection by the defendants as follows:
(i) Page 31: The paragraph commencing with the words ' In consideration of ' to the end of that paragraph concluding with the words 'and the risk assessment process.' That paragraph is deleted. Absent any expertise or knowledge by Inspector Buggy about the underground mining industry, he cannot make any conclusive statement as to comparisons or differences as between the coal mining industry and other industries in New South Wales in 1996.
(ii) Page 34: The paragraph commencing with the words 'Given that it was known ' down to and including the words to the end of that paragraph concluding with the words 'was known (Assumption R 3 ) . ' That paragraph is admitted having regard to the opinions expressed as to risk assessment based on the assumptions relied upon as identified in that paragraph.
(iii) Page 34: The paragraph commencing with the words 'I am of the further opinion' to the conclusion of that paragraph ending with the words 'is unable to determine if this occurred. ' That paragraph is deleted. It is an opinion predominantly based on speculation as to a factual situation that Inspector Buggy has no specialised knowledge of on which to base the opinion expressed.
(iv) Page 37: The last sentence of the first paragraph on that page commencing with the word ' However ' and concluding with the word ' undertaken.' That sentence is deleted. The unequivocal assertion of fact made by Inspector Buggy as part of his opinion is based primarily on one page of a 49 page document which has no accompanying explanation that would enable Inspector Buggy to make such an unequivocal assertion of fact in relation to a matter that he has no factual knowledge of and in an industry with which he is unfamiliar.
(v) Page 37: The last sentence of the third paragraph on that page commencing with the words 'The compulsion ' and ending with the words 'meaningful risk evaluation. ' That sentence is deleted. It is an assumption made by Inspector Buggy excluding any other considerations as to the context in which that document was produced and its application in the area of safety audits being undertaken by the corporate defendant Oakbridge Pty Ltd.
(vi) Page 38: The second sentence of paragraph 4 commencing with the words 'This exhibit does ' and ending with the words 'time of the audit.' That sentence is deleted. It is based on speculation on the basis of the appearance of a comment on one page of a 53 page document dealing with occupational health and safety bench audits conducted in 1995 in relation to a factual background that Inspector Buggy has no knowledge and no specialised knowledge of.
(vii) Page 41: The third paragraph, second sentence commencing with the words 'From the information' to the end of that paragraph ending with the words 'in relation to this consideration .' Those sentences are deleted. It is opinion expressed on the basis of dot point information and any conclusions drawn from that can only be speculative and of negligible weight.
(viii) Pages 44 and 45: Commencing with the first paragraph on page 44 with the sentence commencing with the words 'After perusing this document ' down to and including all paragraphs over to page 45 ending with the words 'the old working of Y WC.' Those paragraphs are deleted. The opinions expressed are based on a document identified as a draft report of the Department of Mineral Resources included in the minutes of a meeting of mine management of the corporate defendants. There is nothing to indicate the basis upon which such a draft document was included in the minutes of the mine managers meeting. There is nothing to indicate what reliance, if any, the defendants were required to place upon that document and there was no evidence elicited by the prosecution from the very person whose name appears on the document, that is, Mr B R McKensey, Chief Inspector of Coal Mines, to attest as to what, if any, was the status of that document. On that basis, no reliance could be placed on any assumptions or opinions expressed on that document, and accordingly those paragraphs that do seek to do so are deleted.
(ix) Page 46: The third paragraph commencing with the words 'Given the assumptions' to the end of that paragraph ending with the words 'the old workings of Young Wallsend Colliery .' That paragraph is deleted. It is an opinion expressed based on assumptions given to Inspector Buggy. In relying on those assumptions Inspector Buggy expresses opinions as to factual matters in relation to the presence of water in circumstances that he has no specialised knowledge of relevant to an industry that he has knowledge or experience of.
(x) Page 46: The third paragraph commencing with the words 'The assumptions provided ' to the end of the paragraph including the words ( 'Assumption R3 :') That paragraph is admitted relying on the assumption indicated by Inspector Buggy.
(xi) Page 46: The fourth and final paragraph on that page commencing with the words 'Given that risk control ' down to and including the words ( evacuate in a direction away from point of inrush ). That paragraph is deleted. It is speculative and based on factual matters in the underground mining industry as to the presence of water about which Inspector Buggy does not purport to have any expertise.
(xii) Page 47: The fourth paragraph commencing with the words 'This is supported by exhibit P86 ' to the end of that paragraph ending with the words 'the old workings of YWC .' This paragraph is admitted except for the words 'from the old workings of YWC .'
(xiii) Final paragraph on Page 47 commencing with the words 'It is observed ' to the end of that paragraph ending with the words 'prior to this audit .' That paragraph is deleted. It is an opinion based on one page of a document and without any other information, is speculative at best. Further, it speculates as to a factual situation that Inspector Buggy has no knowledge of.
(xiv) Page 48: The first two full paragraphs commencing 'With the qualification that it is unclear' down to the end of the second paragraph on that page ending with the words 'the old workings of YWC .' Those paragraphs are deleted. They are qualified, speculative and express an opinion about underground mining work which Inspector Buggy does not purport to have any specialised knowledge of. No reliance can be placed on the opinions expressed in relation to those matters upon which he expresses an opinion relevant to underground mining work and his belief as to the reaction and actions of individuals in factual circumstances he has no knowledge of.
(xv) Page 49: The second last paragraph commencing with the words ' In consideration of' down to and including the words ' and mock emergency drill .' That paragraph is deleted for the reasons as detailed in relation to (xiv) above.
(xvi) The last paragraph on page 49: The first full sentence is deleted such that that paragraph now commences with the words 'Likely controls' down to and including the words 'mock emergency drill .' The first sentence is deleted because it is an opinion based on speculative conclusions that Inspector Buggy makes as to the likely source of water at C heading on facts about which he has no specialised knowledge.
