Key legal question
Whether the insurer could review the renewed request for benefits as a revision of its final 2005 opposition decision.
Extracted holding
No. Once a court has materially ruled on the opposition decision, the insurer may no longer reopen it through administrative revision.
Extracted reasoning
The 2005 opposition decision had already been the subject of a material cantonal judgment in 2006. Administrative revision under Art. 53(1) LPGA was therefore unavailable.
