[39] This is not one of those rare cases. The exculpatory matters relied upon by the appellant had to be weighed against the seriousness of the assault which left Mr Tracey with significant injuries and unable to perform his duties for a number of weeks in circumstances where Qantas has a legitimate interest in ensuring that such behaviour does not occur during "slip time". That is precisely what her Honour did. [21] Moreover, on the facts as found by her Honour, the remark by Mr Tracey that provoked the appellant's attack was in response to a remark by the appellant which was itself deeply offensive. On one view, Mr Tracey's remark was a rejoinder in kind so that the incident may properly be seen as having been initiated by the appellant. While other members may have taken a different view about the weight to be attached to particular exculpatory factors relied upon by the appellant and may, indeed, have come to a different conclusion on whether the termination of the appellant's employment was harsh, unjust or unreasonable, we are unable to conclude that the decision of the Senior Deputy President was, to adopt the words of Stephen J, plainly wrong, her decision being no proper exercise of her discretion. Her Honour's reasons must be given a beneficial reading and, taking that approach, we think her Honour's treatment of the various exculpatory matters does not reflect a failure to give those matters sufficient weight in the relevant sense but rather an attempt by her Honour to explain why they did not move her to conclude that, on balance, the termination of the appellant's employment was harsh, unjust or unreasonable.
