Questione giuridica chiave
Whether the public-law appeal was admissible despite not addressing an alternative cantonal reasoning
Decisione estratta
The appeal was inadmissible because the appellant did not challenge all independent grounds of the cantonal decision.
Motivazione estratta
When a decision rests on multiple independent holdings, each sufficient to support the result, the appellant must attack each of them within the appeal deadline; later submissions cannot cure the defect.
