Whether the appellant had standing to challenge the cantonal decision before the Federal Supreme Court.
He lacked standing because he did not explain any civil claims arising from the alleged offence, and no procedural-right violation was properly raised.
Under Art. 81 LTF, a private complainant must show that the challenged decision may affect civil claims. In complaints against non-entry or dismissal decisions, the appellant must specifically explain such claims in the federal appeal. The file contained no such explanation.
