Whether an appeal to the cantonal social insurance court was admissible against an insurer's decision that was still subject to opposition.
No. Only objection decisions, or decisions for which no opposition is available, may be appealed to the cantonal court; this appeal was filed too early.
The insurer's decision was subject to the statutory opposition procedure under the social insurance rules. Because no opposition proceedings had been conducted and no objection decision had been issued, the court lacked a properly appealable decision.
