Key legal question
Whether the appeal against the cantonal interim order was admissible under Art. 93 LTF.
Extracted holding
The order was an incidental decision, and the appeal was not admissible because neither an exception under Art. 93(1)(b) LTF nor an irreparable harm under Art. 93(1)(a) LTF was shown.
Extracted reasoning
The provisional authorization was limited in time and any environmental impact was not established as irreversible; possible influence on the merits was insufficient.
