Question juridique clé
Whether the federal nullity complaint against the fine-conversion decision was admissible.
Solution extraite
The complaint was admissible insofar as it challenged the conversion order, because such a decision is a substantive decision rather than a mere enforcement act.
Motifs extraits
A fine-conversion decision under Art. 49 No. 3 StGB is subject to nullity complaint review, but a challenge to the underlying final conviction is inadmissible once that judgment has become final.
