Questione giuridica chiave
Whether the complainant could bring a nullity appeal concerning the right to file a complaint under Arts. 29 and 30 Swiss Criminal Code.
Decisione estratta
The complainant could invoke Arts. 29 and 30 SCC only for offences prosecuted upon complaint, but it did not challenge the decisive independent ground of opportunity-based dismissal.
Motivazione estratta
A complainant may use nullity appeal only to complain of violations of the right to file a complaint; here the cantonal decision also rested on an unchallenged independent ground: dismissal in the prosecution's discretion. Because that ground remained intact, the appeal failed.
