The Panel concluded that the Plaintiff suffers from a Personality Disorder Not Otherwise Specified, (DSM IV) with features of a paranoid personality disorder, antisocial personality disorder, and narcissistic personality disorder.
The Panel also considered the possibility that the worker could have a psychotic disorder. While no frank bizarre delusions or hallucinations were identified the Panel noted the worker's continuing rumination in relation to potential work situations and his stated intentions to kill employees of his former workplace. The Panel also noted his seeming indifference to those he has attacked previously and his general restriction of affect in the interview situation. The Panel concluded that elements of a borderline psychotic state were probably present, but a formal diagnosis of a paranoid psychotic disorder could not be substantiated.
The Panel considered the worker does not currently have an Adjustment Disorder based on its consideration of the nature of the Plaintiff's current symptoms and its findings on his presentation at psychiatric examination.
The Panel accepted that the Plaintiff did have an Adjustment Disorder with depressed mood which developed in 1995, as diagnosed by Dr Cooper, in response to workplace stressors at that time. The Panel considers this condition developed independently of his Personality Disorder and it could not be determined to be a recurrence, aggravation, acceleration, exacerbation and/or deterioration of a pre-existing psychological ailment as suggested by the questions from the Court.
The Panel considers the Plaintiff's Adjustment Disorder resolved shortly after the time the Plaintiff ceased his employment (as this was the stressor causing his Adjustment Disorder) with Suncorp Metway in April 1996 and at about the time he thought of acting on his violent and revengeful fantasies, which were symptoms of his Personality Disorder and not his Adjustment Disorder.
Based on the nature of the Plaintiff's symptoms and the Panel's findings on examination, the Panel considers the Plaintiff's employment had no effect on his Personality Disorder as the continued sense of injustice for the events at work were merely a focus of his Personality Disorder and not a cause or an aggravating factor.
The Panel therefore concluded that the Plaintiff is not suffering from any recurrence, aggravation, acceleration, exacerbation and/or deterioration of a pre-existing psychological ailment resulting in a chronic adjustment disorder with mixed disturbances of emotions and conduct and/or anxiety and depression.
As the Panel considers the Plaintiff developed an Adjustment Disorder directly as a result of the circumstances of his employment and that his employment had no effect on his Personality Disorder, the Panel concluded that the Plaintiff's employment with National Mutual, Nexus and Suncorp Metway was not in fact, a significant contributing factor to any alleged recurrence, aggravation, acceleration, exacerbation and/or deterioration of a pre-existing psychological ailment resulting in a chronic adjustment disorder with mixed disturbances of emotions and conduct and/or anxiety and depression.
The Panel does consider the nature and extent of the Plaintiff's Personality Disorder is such that he is not capable of performing any work, but as the Panel has determined that the Plaintiff's initial Adjustment Disorder has resolved and that his Personality Disorder is not related to his employment, it concluded that the Plaintiff has no present inability to return to pre-injury employment arising from an injury.
