Questão jurídica principal
Whether the complainants had standing to file a criminal appeal against the inadmissibility ruling and the no-prosecution order
Decisão extraída
They lacked standing to challenge the merits because they were only denunciants and not victims or private accusers for these ex officio offenses; only formal-denial complaints remained possible.
Fundamentação extraída
Under Art. 81 LTF, simple injured persons or denunciants cannot contest the merits of a decision ending a criminal investigation. The alleged offenses were not prosecution by complaint, and Ticino law did not provide private-accusation standing.
