Question juridique clé
Whether the filing had to be treated as a public-law appeal and was admissible despite the lapse of the dispute's object and the lack of sufficient constitutional motivation.
Solution extraite
The filing had to be treated as a public-law appeal, but it was inadmissible because the dispute had become moot and the appellants did not sufficiently challenge the cantonal procedural dismissal or show a concrete and current interest.
Motifs extraits
A temporary total traffic ban on a non-main road falls under cantonal road sovereignty and is reviewable only by public-law appeal. Since the lower instances decided only a formal strike-off for lack of current interest, the Federal Supreme Court could review only that formal question. The appellants mainly attacked the road closure itself and failed to identify violated constitutional rights or to argue arbitrariness or a likely recurrence of the measure.
