4 On Saturday, 12 December 1998, a family barbecue was held at Ms Thompsett's home. Those present in addition to Ms Thompsett and the applicant, who was then aged 20, were her current partner, Mr P Logan, and a family friend, Mr P Spencer, who had some 12 years previously been her de facto husband. The applicant had been drinking considerable amounts of alcohol during the day and, by the time he arrived at the barbecue, he was said to have been very intoxicated, although he denied to the person who prepared his pre-sentence report that he was intoxicated and maintained that he was in control of his actions. Those at the barbecue were all drinking beer and spirits. During the evening, Mr Spencer made a sexual advance towards Ms Thompsett. This was witnessed by the applicant. She resisted Mr Spencer's advance, but, in the course of it, she was pushed by him, with the result that she sustained quite a severe burn to her arm from the barbecue. The applicant was visibly angry towards Mr Spencer, although he did not react physically. In his interview with the police, he suggested that it reminded him of what the deceased used to do to his mother. After having taken a walk around the block with his mother, who had been upset by the incident, the applicant told both his mother and Mr Logan that he was going to the deceased's flat "to sort him out".
