Kernrechtsfrage
Whether a regional prosecutor had standing to file a nullity appeal to the Federal Tribunal.
Extrahierter Entscheid
Only the cantonal public prosecutor with canton-wide competence may file a nullity appeal; a regional prosecutor lacks standing.
Extrahierte Begründung
Under federal law, the accuser public for the canton is the authority charged with defending the public interest before the cantonal court of last instance. In Valais, the cantonal structure gives the general prosecutor canton-wide competence and supervisory powers, whereas regional prosecutors are limited territorially. Therefore, only the general prosecutor may appeal in nullity.
