Key legal question
Whether Z. had standing as civil party to appeal the police court judgment
Extracted holding
He could appeal only if the criminal judgment could affect his civil claims; because he failed to file civil conclusions or explain their absence, the cantonal court's inadmissibility ruling was not arbitrary.
Extracted reasoning
The court accepted that a civil party may appeal only when the judgment can affect civil claims. Z. did not state concrete civil claims or explain why they were not yet quantifiable, so the refusal of standing was defensible.
