Question juridique clé
Whether the remedy against the cantonal appellate judgment was admissible as administrative/public-law appeal
Solution extraite
The public-law appeal was inadmissible because the remittal decision was incident and caused no irreparable harm, and the administrative appeal was also inadmissible because the appellants lacked a protectable interest in challenging the subsidiary LAT reasoning.
Motifs extraits
The main basis of the cantonal judgment was cantonal law governing restoration under the extraction plan, not directly applicable federal law. The subsidiary LAT discussion could not be reviewed independently since it would not change the dispositive result.
