The 'significant contributing factor' requirement inserted into s 82(1) of the Accident Compensation Act 1985 (Vic) by the 1992 amendments does not apply to physical injuries in the primary sense arising in the course of a worker's employment; it is confined to paragraph (b) (disease) and paragraph (c) (aggravation) injuries. If the requirement does apply, it cannot be equated with a causal connection between a 'work function' or 'employment duty' and the injury — the concept of 'employment' is broader than the performance of work duties.
