Question juridique clé
Whether the appellants were entitled to challenge the refusal to open proceedings against the complainant's counterpart.
Solution extraite
The appeal could not proceed because no criminal offence against the appellant was shown, and the person concerned had no victim or civil-party standing giving rise to a protected legal interest.
Motifs extraits
Under Art. 81(1)(b) BGG, the complainant had no legally protected interest in having the non-opening decision annulled or amended; alleged damage reimbursement did not change this.
