Key legal question
Whether the lower court could, in reformatio in peius, deny all accident causality and eliminate further benefit entitlement beyond 30 Sept 2008.
Extracted holding
The lower court decision could not stand; the case had to be reassessed because the causal question was not sufficiently and reliably established.
Extracted reasoning
The medical record was incomplete and conflicting. The cantonal court relied on an inadequate assessment and went beyond the proper scope of the dispute.
