Questão jurídica principal
Whether the complainant had standing to file a criminal appeal against the non-prosecution decision.
Decisão extraída
He lacked standing because he was neither a private prosecutor nor an injured party within the meaning of the applicable law.
Fundamentação extraída
The public prosecutor had participated in the cantonal proceedings, so the complainant did not prosecute the case alone. He was not directly affected in bodily, psychological, or sexual integrity and therefore was not a victim; as a mere injured person, he could not challenge the merits of the decision.
