15 In his report Dr Cotton said that in 1996 Mr Trueman was suffering from "an acute agitated depressive illness with persistent suicidal ruminations". He had developed a "compulsive phobic avoidance" of dealing with complaints by clients and investigations by the Board. Dr Cotton told the Tribunal that, with treatment from Dr Cotton, Mr Trueman's mental health had improved since then, although there had been lapses. Dr Cotton's evidence was given in August 2000. At that time he told the Tribunal that he thought Mr Trueman would need to receive treatment for a further two years. He said that Mr Trueman could carry on practice provided he did not "take on contentious, difficult clients at an individual level." Not surprisingly, the Tribunal concluded that this view was too optimistic. There is nothing to indicate that, to any significant degree, the findings of unprofessional conduct related to clients who presented particularly difficult issues or who were particularly difficult to deal with. Moreover, commonsense suggested that it would be difficult for a practitioner to identify in advance clients of the kind referred to by Dr Cotton, and difficult to maintain practice on that basis. As well, in view of the number and nature of findings, there remains a doubt whether Mr Trueman is capable of practising within those constraints, and a doubt about his capacity to cope with the demands of managing a practice.
