16.1.3 Where the injury is an uncaused medical event whilst on duty

Delegates will also recall from Part 10 of this handbook, that a sudden, singular medical event such as a 'stroke' or a 'heart attack' mu — st be regarded as an injury and not a disease, even though it may be the inevitable outcome of a prolonged disease process. In line with the 'no fault' doctrine underlying the legislation, spontaneously-arising injuries that occur on duty are compensable, even if there is no workplace contribution to the event, nor any employment related contribution to the underlying disease process.
