“In the context of this case, there are three elements having regard to the issue of loss of control: first, there has to be evidence of a loss of control. There has to be the qualifying trigger – in other words, things were said or done, perhaps over a period of time, in circumstances of an extremely grave character which gave rise to a justifiable sense of being seriously wronged. In terms of there being a loss of control, it is clear to me that there is evidence that the person who executed the killing of Mr Dean potentially was either out of control or was acting with deliberate and considered violence; it was certainly one or other of the two. So to that extent, that limb of the defence is potentially made out. That is not the issue in this case. Even viewing matters entirely on the evidence, as I must, and interpreting that evidence as favourably as one reasonably could towards the viewpoint of Scott Dawson, I really question whether this defence has any mileage at all. There is no doubt the evidence establishes that Mr Dean was extremely irritating over a prolonged period of time, certainly that is a conclusion the jury might be entitled to reach. This was all born from his seeming autism which had not been in any way treated by the time with which we are concerned. Even if one accepts his conduct was acutely aggravating – indeed, there is much evidence to reveal that he was acutely aggravating, not only to the Dawsons but to a variety of other people as well, many of whom have given evidence in the case as to his conduct and how they, as ordinary citizens, reacted to him. Even if one accepts that someone like the Dawsons were entitled to take more than the usual steps that one might take when encountering an aggravating individual, again one questions whether the circumstances were such and so grave a character to give rise to a justifiable sense of being seriously wronged – for example, calling the police; being involved in the court proceedings and taking all the special measures that are asserted to have been taken by the Dawsons in order to protect their property. And accordingly, I come back to the observations of the Lord Chief Justice at paragraphs 60 and 61 of the judgment in the case of Dawes: “For the individual with normal capacity of self-restraint and tolerance, unless the circumstances are extremely grave, normal irritation, and even serious anger do not often cross the threshold into loss of control.”
“46. […] We certainly do not think that the fact that there were at least 18 blows of itself, in the circumstances, gives rise to an inference of loss of control. There is no other evidence identified which might support such a conclusion.”
“60 […] Their effect is that the circumstances in which the qualifying triggers will arise is much more limited than the equivalent provisions in the former provocation defence. The result is that some of the more absurd trivia which nevertheless required the judge to leave the provocation defence to the jury will no longer fall within the ambit of the qualifying triggers defined in the new defence. This is unsurprising. For the individual with normal capacity of self-restraint and tolerance, unless the circumstances are extremely grave, normal irritation, and even serious anger, do not often cross the threshold into loss of control.”
