Question juridique clé
Whether one day of pretrial detention must be credited first against the conditional fine or the additional fine.
Solution extraite
Pretrial detention must be credited first against the main fine; crediting it against the additional fine violated federal law.
Motifs extraits
Art. 51 StGB and the legislative history require detention to be credited primarily against the main sentence. A Verbindungsbusse under Art. 42 Abs. 4 StGB is accessory and of subordinate importance; only if detention exceeds the main sentence may it be credited to the fine.
