Under s10 of the Superannuation Act the primary condition of entitlement was that the plaintiff be discharged after being certified to be incapable, from a specified infirmity of body or mind caused by his being hurt on duty, of discharging the duties of his office. In short, at least directly, the entitlement was based upon the member's discharge from the force by reason of incapacity the result of a particular infirmity itself the result of a work injury and was unrelated at that stage to his earning capacity outside the police force. In this particular case, however, the plaintiff received an additional amount under subs (1A) (b) and (c), in one case commensurate "with his incapacity for work outside the police force" and in the other on the basis that he was totally incapacitated for work outside the police force and, in the opinion of the Board, he was hurt on duty because he was required to be exposed to risks to which members of the general work force would normally not be required to be exposed in the course of their employment. The extra benefit under (b) was related to incapacity for work. The extra benefit under (c) was not simply conditioned upon total incapacity for work but also upon the particular risks to which he was exposed when injured. It did not equate with damages for loss of earning capacity but was an allowance for total incapacity and the existence of a particular danger to which he was exposed when injured. I do not think that these additional benefits, related though they were to a greater or lesser extent to work incapacity, override the essential characteristic of the benefit the plaintiff received as one based on discharge from the police force for incapacity to discharge the duties of his office.
