Key legal question
Whether A.X. had standing to file a constitutional complaint in his own name against the cantonal decision
Extracted holding
He had no legally protected interest because he was not a party to the cantonal proceedings and acted in his own name, not as his son's representative.
Extracted reasoning
Under Art. 88 OG, only a person personally affected and entitled to protect their own legal interests may complain; a power of attorney did not change the fact that A.X. expressly claimed his own standing.
