Key legal question
Whether the federal appeal against the cantonal remand decision was admissible under Art. 93 BGG.
Extracted holding
The remand decision was an interlocutory decision, and neither the requirement of avoiding extensive evidence nor any irreparable harm was met.
Extracted reasoning
Further clarification about the SBB antennas did not amount to a far-reaching evidentiary measure; any additional burden was not significant and could be handled by the cantonal authorities without costly expert evidence.
