Key legal question
Whether the appeal against the cantonal interim order was admissible under Art. 93 BGG
Extracted holding
The interim order could not cause an irreparable legal disadvantage because the insured person would later be joined with full party standing; the appeal was therefore not admissible.
Extracted reasoning
Under the cantonal rule on joinder, the joined person has full party status and can make all procedural submissions. Any delay until after the exchange of written briefs does not create an irreparable harm, and no other ground for immediate challenge existed.
