Questão jurídica principal
Whether the public-law appeal was admissible despite not addressing an alternative cantonal reasoning
Decisão extraída
The appeal was inadmissible because the appellant did not challenge all independent grounds of the cantonal decision.
Fundamentação extraída
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.
