Questão jurídica principal
Whether the appeal against the cantonal remand decision was admissible under Art. 93 BGG.
Decisão extraída
The appeal was inadmissible because the appellant failed to show irreparable legal harm or that immediate review would avoid extensive evidence proceedings.
Fundamentação extraída
A remand decision is an interim decision under Art. 93 BGG. The appellant did not address the admissibility requirements and mistakenly treated the decision as final. No irreparable legal disadvantage was apparent, since a future unfavorable final cantonal decision could still be challenged.
