Question juridique clé
Whether BAG could appeal the remand decision despite being a first-instance authority in an insurer competence dispute.
Solution extraite
BAG did not show a non-reparable legal disadvantage under Art. 93(1)(a) BGG; the appeal was therefore not admissible.
Motifs extraits
A remand requiring further fact-finding is an interlocutory decision. In this specific Art. 78a UVG setting, the eventually liable insurer can later challenge both the BAG decision and the final judgment, so no irreparable denial of judicial review arises for BAG.
