6 The second question identified by Mr Ower, counsel for the appellant, was whether it was open for the trial judge to bridge the evidentiary gap in the medical evidence in the way he did. His Honour's ultimate conclusion on the second question was:
"To a mind uninstructed in pathology the sequence of events described in the plaintiff's evidence, suggests that after September 2001 plaintiff was subjected to a number of critical incidents, as he put it, in the course of his police service which inspired fear in his mind and, as I full accept caused him raised stress on a chronic basis after they occurred.
He did not, it is true, develop atrial fibrillation in immediate temporal proximity to these critical incidents. His assertion was that they simply added to his general stress levels and contributed to the feeling of being 'stressed out' and unable to sleep. He did not say that in immediate temporal proximity to them he experienced the chest tightening feeling he described as being like a rubber band stretched around his chest. This only occurred, on his evidence, from time to time.
However, he did describe a picture of gradually increased emotional stress from September 2001 until his eventual application for medical discharge, including the period after he went on sick leave in April 2004 and before he eventually left the police residence and moved to his own house at Dungog a considerable number of months later. It was during this period of time that his admission to Maitland Hospital with atrial fibrillation occurred.
To a mind uninstructed in pathology, this series of events would suggest a connection between his development of paroxysmal atrial fibrillation and the gradually increasing stress he described at work."
