Questão jurídica principal
Whether the cantonal decision on expert bias was directly appealable under Art. 92 BGG / Art. 56 ATSG
Decisão extraída
A decision on an objection to an expert's impartiality is appealable as a separate interlocutory decision under Art. 92 BGG; the procedural route question was nevertheless left open because a remand would otherwise be a pointless formal exercise.
Fundamentação extraída
The Court held that, even if the decision were interlocutory, it concerns an exclusion request and is therefore immediately challengeable. Since all parties needed clarity on the bias issue for the continuing insurance proceedings, the Court decided the matter rather than remitting only on admissibility.
