In this case you may consider that the accused had the opportunity to retreat or desist from any further confrontation, but failed to do so. Although the law does not require people to retreat from an attack before defending themselves, you can take into account a failure to do so when determining whether the accused believed that what he was doing was necessary in self-defence. A failure to take obvious evasive action is also one of the factors that you can take into account in deciding whether the accused's belief in the necessity of his actions, was based on reasonable grounds.
In this case you have also heard that it was the accused who started the confrontation with Paterson's girlfriend, by first taking the chairs and then responding in an abusive manner and escalating the confrontation when she took some chips.
The law says that people who start an attack cannot then claim that they acted to defend themselves against a counterattack, unless their original aggression had ended at the time of that counterattack. However, if [they] end their aggression but are then required to defend themselves against a new attack, the law allows them to raise self-defence.
You will, therefore, need to determine whether the accused started the attack in this case, and if so, whether he ended his aggression by the time he says he defended himself.
If the prosecution has proven beyond reasonable doubt, that his aggressive behaviour had not ended at the relevant time, then you must find that he did not act in self defence. Here, the prosecutor submitted, that the acts of the accused amounted to escalating aggression. He was armed even before there was any threat of physical violence upon him and he was ready to attack with a weapon.
Even if you determine that the accused had ended his aggressive behaviour, and so can legitimately claim that he acted in self defence, the fact that he started the confrontation will be one of the factors for you to consider in determining whether he believed that his acts were necessary. You can also take it into account in deciding whether the accused believed it was based on reasonable grounds.
In making your determination, you should take into account, matters such as the extent to which the accused declined further conflict, stopped using force or attempted to retreat. In response, Mr Langslow submitted that it was Paterson who was the aggressor, and he admitted that he intended to stop him, referring to the accused, and probably throw a punch. The accused was merely standing his ground.
Mr Langslow says that the CCTV footage only shows the accused reaching out to maintain his balance. He said that if he had knives, which he later threw away, this did not prove a guilty conscience of what happened earlier; merely did not want to be found with knives. Mr Langslow submitted that maybe the accused did have a knife, but you cannot see it clearly and should have a doubt about that.
