Questione giuridica chiave
Whether refusal to pay family allowances older than 24 months was arbitrary under Art. 9 Cst. despite mistaken advice from the school administrator.
Decisione estratta
No. The administrator was not competent to bind the family-allowance fund, so the good-faith principle could not extend the statutory time limit.
Motivazione estratta
Protection of good faith requires an assurance from an authority acting within its competence and capable of binding the competent body. That condition failed here.
