Key legal question
Whether X. had standing to challenge the dismissal of the proceedings against Y.
Extracted holding
He lacked standing because he had not asserted civil claims and did not show how the dismissal could affect any civil claim; he also raised no arguable procedural-rights violation under Star-Praxis.
Extracted reasoning
Under Art. 81(1)(b)(5) BGG a private complainant must show an impact on civil claims; for dismissals, this must be explained before the Federal Supreme Court. That was not done here.
