Question juridique clé
Whether the federal appeal against the cantonal decision striking the interim-measures case was admissible despite lack of current interest.
Solution extraite
The appeal was inadmissible because the appellant no longer had a current, legally protected interest when filing the appeal.
Motifs extraits
The first-instance court had already decided the merits, and the dispute over stopping the works was now within the pending cantonal appeal on the merits. Any federal remand would again lead to mootness, so no practical benefit remained.
