Kernrechtsfrage
Whether the appellant had standing to challenge the dismissal of the criminal investigation
Extrahierter Entscheid
No standing, because the appellant had expressly renounced private-plaintiff rights and showed no impact on civil claims.
Extrahierte Begründung
Under Art. 81 BGG, a private complainant must show that the challenged decision may affect concrete civil claims. The house-right interest asserted was insufficient, and the written waiver of private-plaintiff rights excluded any such effect.
