Questione giuridica chiave
Whether the federal appeal was admissible against the cantonal tax judgment and against the lower decisions themselves
Decisione estratta
The appeal was admissible in principle against the cantonal judgment, but the request to annul all prior decisions was inadmissible because they were replaced by the appellate judgment.
Motivazione estratta
The devolutive effect means only the appellate judgment can be challenged independently; prior decisions are deemed included in the appeal.
