"Carrying a knife anticipating using it to attack another person cannot amount to a good reason – if sure it was carried for that purpose, the defence would not apply, and the D would be guilty. The general carrying of a knife over a period of time in case of attack would not amount to a good reason. Carrying a knife out of self-defence (as above) – in other words, due to fear of an imminent attack - may amount to a good reason. You decide whether the D genuinely thought he was at risk from an imminent attack; if so, how imminent, how likely and how serious did he believe it would be? Decide what the facts are, and what was in the D’s mind, then decide if in your view he has persuaded you that it is more likely than not that that amounts to a good reason."
"That in itself reflects the evidence that Duraab Khan had threatened you on a number of occasions and that you were in fear of him. But on the basis that you already had the knife in your car, the verdict in my view is not determinative of whether you believed that Duraab Khan was heading to your family home on 31 January, nor is it determinative as to whether that purpose continued into this incident."
"I am satisfied on the evidence that what you did was what you intended to do when getting out of the car and was not a spontaneous reaction brought about by Duraab Khan's actions."
