Questione giuridica chiave
Whether the municipal appeal still had an actual and practical interest after the permit period had expired
Decisione estratta
Yes. The dispute could recur every winter and was capable of evading timely federal review; the issue therefore remained reviewable.
Motivazione estratta
The court accepted both current interest because the lower judgment treated the structure as permanently licensable and the public-interest exception because the same question could recur under similar conditions.
