Questione giuridica chiave
Whether the cantonal appeal decision violated the right to be heard by relying on an undisclosed psychiatric report.
Decisione estratta
Yes. The report was central to the decision and had not been shown to the appellants, so the hearing right was infringed.
Motivazione estratta
Parties must be informed of new decisive materials and given the chance to inspect and comment on the file. Since the report was not disclosed and was important for the outcome, the defect could not be cured on appeal.
