But Giles said that on May 6 of last year, her client \u201cdecided to leave\u201d Robson<\/a>.<\/p>\n

In his South Auckland sleepout where she was staying, Green began to pack her suitcase, Giles said.<\/p>\n

However, the woman never made it to the gate with her belongings, Giles continued, as \u201csomething happened that changed everything\u201d.<\/p>\n

It has never been in dispute that Green fatally stabbed Robson, Giles said, but the Crown wanted the jury to believe that the \u201csomething\u201d was murder.<\/p>\n

\u201cIt is not,\u201d she stated.<\/p>\n

The jury needed to decide whether Green was acting in self-defence, Giles said, and to do so they needed to put themselves in Green\u2019s shoes.<\/p>\n

Giles told the court Green suffers from complex post-traumatic stress disorder (CPTSD) and a traumatic brain injury, which can \u201cheighten a person\u2019s perception of threat\u201d.<\/p>\n

She alleged Green stabbed Robson in response to him \u201churting her\u201d.<\/p>\n

\u201cWhether or not that was reasonable in the circumstances is a matter for you to consider.\u201d<\/p>\n

The jury would hear from a \u201cleading expert\u201d on intimate partner violence who would explain how victims behave, based on knowledge rather than misconceptions, Giles said.<\/p>\n

First up, however, was forensic psychiatrist Dr Jacqueline Short, who had assessed Green after multiple sessions.<\/p>\n

Early childhood adversity, inter-familial violence and intergenerational trauma<\/p>\n

Short appeared via audio-visual link and detailed what she had learned about Green\u2019s personal history, which she said was one of early childhood adversity, inter-familial violence and intergenerational trauma.<\/p>\n

Short said Green suffered early physical and emotional abuse and disrupted attachment, particularly from her mother, who was \u201cabsent\u201d and \u201cemotionally unavailable\u201d while she battled addiction.<\/p>\n

When Green was 17, her life was \u201cmarked\u201d by a serious assault; later, as an adult, she suffered repeated intimate partner violence .<\/p>\n

That combination of her early and adult life experiences had caused Green to develop CPTSD, the doctor said.<\/p>\n

As opposed to post-traumatic stress disorder (PTSD), she explained CPTSD was the result of repeated traumas with multiple exacerbated triggers and symptoms.<\/p>\n

Green was experiencing CPTSD by 2017, when an \u201caggressive coercive act\u201d happened to her while she was trying to leave a violent partner, Short said.<\/p>\n

She was seriously assaulted by another intimate partner the following year, Short continued, leaving her with a traumatic brain injury and concussion disorders.<\/p>\n

By this point, Green was \u201chyper-sensitised\u201d to potential threats, projecting a tough self-image as a coping mechanism and having angry outbursts if that image was threatened, the doctor said.<\/p>\n

As well as those flashes of rage, Green was prone to shutting down or \u201cblunting\u201d both responses, particularly in reaction to violence and perceived violence, Short explained.<\/p>\n

Green was also prone to \u201cblacking out\u201d or \u201czoning out\u201d in those outbursts, meaning she had no memory of what had happened.<\/p>\n

Short said the condition family members saw Green to be in immediately after the stabbing<\/a> \u2013 shaken, flustered, lost and not saying anything \u2013 was consistent with dissociation, or shutting down, brought on by trauma.<\/p>\n

Giles brought up what Green had said to wh\u0101nau member Jessica Tahere, that she had \u201cschiz\u2019d out\u201d and become that \u201cother person\u201d and slit Robson\u2019s artery.<\/p>\n

It was Tahere\u2019s evidence that Green spaced out after that confession, then came to and acted as if nothing had happened.<\/p>\n

\u201cIt says to me that Ms Green was trying to make sense of what happened at that time and was not able to do so,\u201d Short said in evidence.<\/p>\n

Al-Janabi zeroed in on the fact that a traumatic brain injury was a \u201cbroad category of injury\u201d which, apart from headaches and sensitivity to bright lights, hadn\u2019t significantly impaired Green. Short agreed.<\/p>\n

The prosecutor asserted that Short couldn\u2019t comment on Green\u2019s intent \u201cat the moment of the stabbing\u201d.<\/p>\n

\u201cYes, I don\u2019t speak to the ultimate issue,\u201d she replied.<\/p>\n

Intimate partner violence<\/p>\n

The court then heard from intimate partner violence expert Rachel Smith, who had no prior knowledge of the case and was called on to dispel common misconceptions about family violence and its victims.<\/p>\n

There were many false public misconceptions about victims of family violence and their behaviours, she said, including the outdated term of \u201cbattered women\u2019s syndrome\u201d.<\/p>\n

It was a \u201ccommon myth\u201d that victims were passive and that \u201ctrue\u201d victims don\u2019t use \u201cresistance\u201d. Smith had found in her research that the opposite was true.<\/p>\n

This included violent resistance, Smith said, explaining that victims would use force to stop force.<\/p>\n

She also said long-standing patterns of abuse meant that victims of family violence were not necessarily responding to an immediate threat, but to what they knew had happened to them in the past.<\/p>\n

They respond to \u201ceverything their partner\u2019s ever done to them\u201d, she said, and threats were \u201cmade credible\u201d by what\u2019s happened historically.<\/p>\n

These responses and acts of resistance can be exacerbated if the abuser is in a position of power \u2013 such as a gang member or police officer, for example, she said.<\/p>\n

They can also be made worse by the victim being in a lower socioeconomic position, which, coupled with a fear of those around her, could make it more difficult for a victim to get outside help, Smith said.<\/p>\n

Al-Janabi pointed out that Smith was there for educational reasons and not to comment on what happened between Green and Robson.<\/p>\n

She asked Smith if that issue was outside her area of expertise.<\/p>\n

Smith responded that she did have experience, having read more than 100 intimate partner violence police homicide reports and finding what were \u201cdistinct patterns\u201d.<\/p>\n

The Crown and defence will give their closing addresses tomorrow and Justice James MacGillivray will sum up the case on Monday before the jury begins its deliberations.<\/p>\n
