Key legal question
Whether the injured party had standing to challenge the cantonal decision by constitutional complaint
Extracted holding
The complainant lacked standing on the merits because he had only a factual, not a legally protected, interest in prosecution and punishment.
Extracted reasoning
Under settled case law, an injured party may only raise violations of procedural rights amounting to a formal denial of justice; he may not contest the merits or evidentiary assessment. No such procedural-rights violation was sufficiently alleged.
