Key legal question
Whether the appeal against the cantonal remand decision was admissible under Art. 93 BGG
Extracted holding
The remand decision was a separately appealable interim decision only if the strict conditions of Art. 93(1) BGG were met; here neither irreparable harm nor the exception of Art. 93(1)(b) BGG was satisfied.
Extracted reasoning
The cantonal court imposed no binding substantive instructions, only ordered additional factual investigation. The resulting prolongation of proceedings did not amount to irreparable harm, and the required additional evidentiary effort was not sufficiently significant.
