Questão jurídica principal
Whether the conversion of an old final customs fine into substitute detention must be assessed under new StGB transitional rules or under the old VStrR rule.
Decisão extraída
The conversion remains governed by the old law; Art. 388 StGB applies to execution of earlier judgments, and the milder-realty rule of Art. 2 StGB does not extend to this post-finality conversion.
Fundamentação extraída
The court held that Art. 2 StGB concerns the temporal reach of substantive criminal law before final judgment, whereas Art. 388 StGB governs execution of earlier judgments. A fine-conversion decision is part of the execution of a prior judgment in the sense of Art. 388 StGB.
