Key legal question
Is the subsidiary constitutional complaint admissible against the cantonal interlocutory decision on passive standing?
Extracted holding
No. The decision was based on federal social insurance law and could be challenged by administrative appeal to the Federal Insurance Court; the subsidiary constitutional complaint was therefore excluded.
Extracted reasoning
The cantonal court decided under federal law, not autonomous cantonal law. The challenged ruling was thus a federal public-law decision in social insurance matters and not a matter for subsidiary constitutional review.
