Questão jurídica principal
Whether a judicial appeal is admissible without first filing an opposition to the insurer's formal decision under LAMal
Decisão extraída
The appeal is inadmissible if the opposition stage was bypassed; the filing must be treated as an opposition and sent to the insurer.
Fundamentação extraída
Compared with the former LAMA, LAMal introduced an opposition procedure between the insurer's formal decision and judicial proceedings before the cantonal insurance court. That step is a condition of admissibility.
