"9(2)(a) the degree of disablement due to service of a member of the armed forces shall be assessed by making a comparison between the condition of the member as so disabled and the condition of a normal healthy person of the same age and sex, without taking into account the earning capacity of the member in his disabled condition in his own or any other specific trade or occupation, and without taking into account the effect of any individual factors or extraneous circumstances; (b) for the purposes of assessing the degree of disablement due to an injury which existed before or arose during service and has been and remains aggravated thereby - (i) in assessing the degree of disablement existing at the date of the termination of the service of the member, account shall be taken of the total disablement due to that injury and existing at that date; and (ii) in assessing the degree of disablement existing at any date subsequent to the date of the termination of his service, any increase in the degree of disablement which has occurred since the said date of termination shall only be taken into account in so far as that increase is due to the aggravation by service of that injury; (c) where such disablement is due to more than one injury, a composite assessment of the degree of disablement shall be made by reference to the combined effect of all such injuries; (d) [subject to sub-paragraph (e),] the degree of disablement shall be assessed on an interim basis unless the member's condition permits a final assessment of the extent, if any, of that disablement; ... (3) The degree of disablement assessed as aforesaid shall be certified by way of a percentage, total disablement being represented by 100 per cent (which shall be the maximum assessment) and a lesser degree being represented by such percentage as bears to 100 per cent the same proportion as the lesser degree of disablement bears to total disablement..."
"The decision of the tribunal may, at the discretion of the tribunal, be announced by the chairman immediately after the hearing of the case, or may be communicated in writing to the appellant and the Secretary of State within seven days after the tribunal has reached its decision, and in either case the chairman shall indicate the tribunal's reasons for its decision."
"It follows that, if the appellate process is to work satisfactorily, the judgment must enable the appellate court to understand why the judge reached his decision. This does not mean that every factor which weighed with the judge in his appraisal of the evidence has to be identified and explained. But the issues the resolution of which were vital to the judge's conclusion should be identified and the manner in which he resolved them explained. It is not possible to provide a template for this process. It need not involve a lengthy judgment. It does require the judge to identify and record those matters which were critical to his decision."
"There are two lessons to be drawn from these appeals. The first is that, while it is perfectly acceptable for reasons to be set out briefly in a judgment, it is the duty of the judge to produce a judgment that gives a clear explanation for his or her order. The second is that an unsuccessful party should not seek to upset a judgment on the ground of inadequacy of reasons unless, despite the advantage of considering the judgment with knowledge of the evidence given and submissions made at the trial, that party is unable to understand why it is that the judge has reached an adverse decision."
"The tribunal heard from Mr Viggers that he has significant mobility and mental problems. We do not accept that these are of the severity described to us by Mr Viggers. In particular we note that Mr Viggers has had no special adaptations made to his house. Mr Viggers has a mobility car but is capable he does use this for long journeys such as to London to visit his friend who lives in Acton and he drove to today's hearing. We also note that contrary to his oral evidence, Mr Viggers displayed excellent recall and concentration during the Tribunal Hearing which was over some two hours in duration. "
"The Tribunal heard detailed and comprehensive evidence from Mr Viggers and his two witnesses. Mr Viggers' main concern is that he failed to realise the extent of his dysthymic disorder until 1993 when he then sought treatment. The evidence before the Tribunal was that there is no contemporaneous medical history of mental problems until the early 1990's. We found Mr Viggers a plausible but inconsistent witness. Mr Viggers between 1976 and 1995 managed to hold down jobs with both London Transport and British Rail, both of which involved significant responsibility and passenger safety. We find that Mr Viggers, on his own evidence, displayed pedantic tendencies, and on that of his witnesses Mr Perrat who said Mr Viggers did "not suffer fools"
