On 10 November 2021, the Supreme Court issued an interesting decision in the matter of Chahrouk v Allianz Australia Insurance Limited [2021] NSWSC 1457 (10 November 2021).
From this case we can see the importance of clearly explaining any argument (or counter argument) on causation, in relation to each and every specific injury alleged. Of course, one cannot ensure that a medical assessor does in fact consider the argument - but at least there will be grounds to seek Review.
In addition, where a specific scientific study is material to a decision, then it ought to be identified in the decision, but a Panel is entitled to rely on settle medical facts and theories without elaborating on the source of that knowledge.
