Questão jurídica principal
Whether the mother had standing to appeal on behalf of her son, who had reached majority, and in her own name against the confirmation of placement.
Decisão extraída
She had no authority to appeal on behalf of her adult son and no personal standing under Art. 81 LTF.
Fundamentação extraída
A parent's legal power to represent a child ends, absent a special tutelary decision, once the child reaches majority. Because the son was already an adult, the mother could not act for him; nor did she show a personal legal interest.
