45 As to the second ground, it seems to me that, if the applicant is right in his suggestion that Roberts-Smith JA did not view the videotape, there was no need for him to have done so. Even if the contents of that videotape are admissible, the best evidence of what took place in the course of the assault, so far as the applicant is concerned, is that which he gave himself under oath at the murder trial. Moreover, as I have said, the applicant had told Roberts-Smith JA that there was no significant variation between the account that he gave to the police and the account that he gave in evidence. I have viewed the videotape and, to a large degree, that statement is correct. Such differences as there are seem to me to work against, rather than for, the applicant's prospects of raising a defence to the charge of assault occasioning bodily harm. So, for example, the applicant told the interviewing police officers that his wife had had a few drinks but that she "seemed to be in her right frame of mind". He said that the anger that he felt towards his wife at the material time was a product of her neglect of the family and her refusal to discuss the issue with him. He said nothing of any other form of provocation prior to the time when he pushed his wife against the wall, causing her nose to bleed and her head to hit the wall. While he said that his wife had thereafter kept coming towards him and "effing and blinding", and that he had pushed her away in self-defence, he also said that he had followed her into the laundry (because she kept "hurling" insults at him) and that he had pushed her in the direction of the stairs because he knew that they were carpeted.
