Key legal question
Whether the appellants had standing to challenge the cantonal refusal to promote the prosecution
Extracted holding
The public-law appeal was admissible only insofar as it challenged the denial of party status, not on the merits of the criminal complaints.
Extracted reasoning
Injured parties without victim status generally lack standing to contest the merits of a decision refusing prosecution; they may only complain of formal denial of justice and procedural rights violations.
