Key legal question
Whether the federal appeal was admissible against the cantonal remand judgment as an interlocutory decision under Art. 93 BGG.
Extracted holding
The appeal was inadmissible because the appellant failed to show any irreparable harm or other ground under Art. 93(1) BGG; the remand judgment could be challenged later together with the final decision.
Extracted reasoning
The cantonal judgment was not final since the permit procedure remained open and the attic-floor issue was sent back for redetermination. The appellant did not address the special admissibility requirements for interlocutory decisions, and none were apparent.
