Questão jurídica principal
Whether X.________ had standing to appeal the labor judgment despite not being a party below
Decisão extraída
No. A person who was not a party to the first-instance proceedings and does not act on behalf of the actual party has no standing to appeal.
Fundamentação extraída
The appeal was filed in X.________'s own name, and nothing showed that he was acting on behalf of his wife B.________; therefore he was not entitled to appeal under Art. 308 CPC.
