Key legal question
Whether the appellant had standing to appeal a ruling that was favorable to him.
Extracted holding
He had no legally protected interest in the annulment of a decision rendered in his favor, so the appeal was inadmissible.
Extracted reasoning
Under Art. 382(1) CPP, only a party with a legally protected interest may appeal. Because the first-instance ruling admitted the opposition and remitted the case for further proceedings, the appellant suffered no legal disadvantage.
