Question juridique clé
Whether the cantonal administrative judge arbitrarily declared the appeal moot for lack of current practical interest.
Solution extraite
No arbitrariness was shown; the requirement of a current practical interest could be applied because the appellants were no longer using the land and the owner had not appealed.
Motifs extraits
Under the cantonal procedural law, the clerk/judge may strike a case from the roll once it has become moot. The Federal Supreme Court accepted that an exception to current interest may exist for repeatable short-lived measures, but found it was not arbitrary here to require such interest given the appellants' own decision to end their stay and the absence of an appeal by the addressee of the municipal decision.
