Questione giuridica chiave
Whether the cantonal appeal became moot after the tax commission withdrew its objection decision
Decisione estratta
Yes. Once the challenged objection decision was fully revoked, the prerequisite for a merits decision disappeared and the cantonal appeal was properly declared moot.
Motivazione estratta
Under cantonal procedural law, the lower authority may amend or revoke its decision while the appeal is pending. A full revocation restores the situation to the stage before that decision; the assessment is not final until a new objection decision is issued.
