Questione giuridica chiave
Whether the appeal against the challenged summons was still admissible after the hearing had already taken place.
Decisione estratta
The appellant no longer had a current practical interest in having the summons reviewed, so the appeal was inadmissible.
Motivazione estratta
Because the cantonal appeal was dismissed and the hearing was maintained and held on the scheduled date, the later federal appeal could no longer affect the situation; the contested summons had become moot.
