30 Returning to this case, Mrs Matthews has identified 15 witnesses, who gave evidence at the Victorian Bushfire Royal Commission,[19] who may fall into this category. In some instances, the witness will give evidence as to factual matters as a result of an inquiry carried out for purposes unrelated to this proceeding- for instance, a forensic expert engaged by Victoria Police or the Coroner to examine the cause of the fire in addition to giving evidence as to the observations and tests, may also be asked to express an opinion, such as the probable cause of the fire. That expert may, because of employment or contractual restrictions or personal inclination, be unwilling to provide an expert report complying with r 44.03. The Court should not, subject to what I am about to say, be deprived of the assistance of that opinion. Another example that comes to mind and relevant in this case is a person engaged by one of the defendants (say, and purely as an example, SPI or the CFA) whom Mrs Matthews wishes to call to give factual and opinion evidence. That person, understandably, will not commit to a r 44.03 report, particularly where there may be employment obligations inconsistent with those imposed by O 44 and the Code.
