Key legal question
Whether the fire police had competence to issue an occupancy order with Art. 292 StGB warning while a recourse against a prior building-inspector order was pending.
Extracted holding
This competence question is governed by cantonal law and is therefore not reviewable on federal nullity appeal; the fire police's competence was not found to be invalid on the record.
Extracted reasoning
The Federal Supreme Court held that only violations of federal law can be raised on nullity appeal. The alleged lack of competence depended on cantonal procedural law. The lower court's view that fire police may independently order fire-safety measures, even if building authorities also acted, was not contrary to federal law.
