Key legal question
Whether X. was entitled to challenge the discontinuance of the forgery investigation before the Federal Supreme Court
Extracted holding
X. lacked standing because he was neither a private prosecutor nor an injured party within the meaning of Art. 81 BGG, and a mere damaged person is not entitled to appeal.
Extracted reasoning
Participation of the prosecutor in the cantonal proceedings excluded private-prosecutor status; forgery does not directly affect bodily or psychological integrity, so victim status was absent; as a non-victim damaged person, the appellant had no appellate legitimacy.
