Questão jurídica principal
Whether the appeal against the remand decision was admissible under Art. 93 BGG.
Decisão extraída
The appeal was inadmissible because the remand decision caused no irreparable harm and would not enable an immediate final decision that would save substantial time or costs.
Fundamentação extraída
The appellant did not address the admissibility requirements. The remand concerned only further factual clarification and did not impose binding substantive instructions. The remaining psychiatric clarification also prevented a final ruling.
