Whether the cantonal social insurance court could hear a direct appeal against the insurer's decision of 18 November 2010
The appeal was inadmissible because the decision was subject to prior opposition before the insurer.
Under Art. 56 al. 1 LPGA, only decisions on opposition or decisions for which opposition is unavailable may be appealed. The challenged accident-insurance benefits decision was an appealable decision under Art. 49 and 52 LPGA, so the opposition remedy had to be exhausted first.
