Key legal question
Whether the Federal Office had standing to appeal the cantonal judgment despite the limited scope of the challenged point.
Extracted holding
The appeal was admissible because the contested finding on Betriebsnähe had an autonomous legal effect and a public interest in correct application of Art. 24b RPG remained.
Extracted reasoning
The finding would bind future proceedings and the federal authority may ensure uniform application of federal law; the appeal was not limited to private interests.
