“‘Injury’ includes any injury or disease, whether of body or of mind, ‘injury received in the execution of duty’ has the meaning assigned to it by Regulation A11 and ‘the result of an injury’ shall be construed in accordance with Regulation A13; …”
“In my professional judgment, Mr Davidson’s ill health leading to his retirement was attributable to his employment to a considerable degree. I deem his continuing symptoms to be causally related to medico-legal reasons arising directly out of that employment both prior to and subsequent upon his retirement. These include the procedures and protocols required by his employer and the effect on him of the interventions and delays inherent in the systems used by that employer. To date I have seen no evidence to suggest, convincingly, that challenges unconnected with his employment have contributed to his mental ill health. On these grounds his earning capacity has been adversely affected to a significant degree. From my extensive experience in this field, I believe that an early and conclusive resolution of these issues would allow the appellant to recuperate his mental health and, in due course, to achieve the earning potential of which I and, by its own submission, the SW Police Authority itself, judge him capable. In this regard I would expect him able to achieve an annual income in substantial excess of the£2000 to£5000 he is currently earning through painting and decorating From my current examination of the individual and his history to date, I would assess his disability attributable to an injury sustained in relation to his employment to be at the major level: i.e. 51 – 75%.” (Emphasis as in the original.)
“Where it is necessary to determine the degree of a person's [inability, occasioned by infirmity of mind or body, to perform the ordinary duties of a … member of the force], it shall be determined by reference to the degree to which his earning capacity has been affected as a result of an injury received without his own default in the execution of his duty as a member of a police force”
“Where a person is disabled partly on account of a medical condition occasioned by an injury on duty and partly by another medical condition which has not been occasioned by a relevant injury, the degree of disablement must be assessed on the basis of an apportionment of the disablement to take account only of the condition occasioned by the relevant injury.”
“To what degree has the appellant’s earning capacity been affected by the relevant injury (an anxiety state and depression) received in the execution of duty?”
“When a person is disabled partly on account of a medical condition occasioned by an injury on duty and partly by another medical condition which has not been occasioned by a relevant injury, the degree of disablement must be assessed on a basis of apportionment on (sic) the disablement to take account only of the condition occasioned by the relevant injury.”
