Kernrechtsfrage
Whether the appeal could be directed separately against lower-instance decisions and the original permit.
Extrahierter Entscheid
The lower-instance decisions were not separately appealable; the original permit was replaced by the final cantonal decision and could only be challenged indirectly.
Extrahierte Begründung
Under the devolutive effect, only the last cantonal decision is directly appealable; alleged defects in the original 2009 permit or deviations from it had to be raised separately before the competent authority.
