Questão jurídica principal
Whether the cantonal remand order constituted a reformatio in peius requiring warning and the possibility to withdraw the appeal
Decisão extraída
No. A remand for additional fact-finding and new assessment does not amount to a reformatio in peius unless a worsening is certain.
Fundamentação extraída
The mere possibility of a less favorable outcome after annulment of the administrative decision and remand for further investigation is not enough; only a certain worsening would trigger the warning requirement. Here the renewed assessment could also leave the claimant unchanged.
