32. Third, her Worship's finding seemed to have been based upon the assumption that as no-one who punches a person with sufficient force to knock him to the ground on three occasions could fail to have adverted to the risk of causing fractures or other damage to that person's facial bones but in my view there was no adequate basis for such an assumption. In some circumstances a court may act upon a presumed fact by taking "judicial notice" of it, but the test is a stringent one. Judicial notice may be taken of a fact which is "so generally known that every ordinary person may be reasonably presumed to be aware of it": Holland v Jones [1917] HCA 26; (1917) 23 CLR 149 at 153 per Isaacs J. It has been suggested that the test should be dependent upon the presumed knowledge of "educated men" per Dixon J in Australian Communist Party v Commonwealth [1951] HCA 5; (1951) 83 CLR 1 at 196 or "every well informed person in Australia" per Evatt J in Deputy Federal Commissioner of Taxation (NSW) v W R Moran Pty Ltd [1939] HCA 27; (1939) 61 CLR 735 at 806. However, I am not satisfied that ordinary people, whether educated males or other well informed members of the Australian community, have any real knowledge of the thought processes of those who commit assaults of that nature. Indeed, I suspect that most people would think that such assaults are acts of mindless violence committed with little if any thought for the consequences. The position might be quite different when a weapon is used or there is some other act such as pushing someone from an elevator to a balcony which obviously creates grave danger for the victim. However, in my view, the proposition that any man who assaults another by punching him with his bare hands has actually adverted to the risk of damaging the victim's cheekbones is not a "fact" within the knowledge of all reasonably well informed members of the community.
