22 The defendants submit that I should adopt the observation of the trial judge in the plaintiff's first trial, found at paragraph 17 of his Reasons for Judgment, to the effect that if the plaintiff did not know of the relevant provisions of the Act then he was negligent in his ignorance.[6] The difficulty with this submission is that this is a new trial. There is new evidence and I must reach my own conclusions about the facts and the credit of the plaintiff. I note the observation by Buchanan JA in the Court of Appeal[7] that "there is no requirement, in every case, that delay be satisfactorily explained". I am prepared, however, to accept that if I were to reject the plaintiff's claim of ignorance it would be a significant matter in the exercise of discretion to extend time. This is because the claim of ignorance lies at the heart of the plaintiff's explanation for his delay and to reject his claim of ignorance would be to reject an important ground upon which the plaintiff relies to persuade the court that his failure to apply within the time should be excused. I accept that in the case of an ordinary functioning legal practitioner who denied knowledge of his right to make a claim against his father's estate an attack on his credibility may have had resonance. But, the plaintiff was no ordinary functioning legal practitioner. His life was deeply troubled, he was depressed, he had a serious drinking problem and was quite obviously not functioning properly as a lawyer or as a husband or father as he readily concedes.
