Kernrechtsfrage
Whether the nullity appeal was admissible despite prior municipal and district-court proceedings.
Extrahierter Entscheid
The appeal was admissible because the district court's appellate judgment was not treated as a single cantonal instance under Art. 268 ch. 1 PPF.
Extrahierte Begründung
The initial municipal sentence remained effective until modified on appeal and was not transformed into an indictment or nullified by the mere filing of an appeal; therefore the cantonal appellate court did not act as a final single instance.
