Questão jurídica principal
Whether Art. 20 StGB applied because the appellant acted under an excusable mistake of law.
Decisão extraída
Art. 20 StGB did not apply because the appellant knew that selling hemp products with THC above 0.3% was unlawful; any claimed lack of awareness contradicted the binding findings.
Fundamentação extraída
The court held that the appellant had been expressly warned in 1998 about the impermissibility of products exceeding 0.3% THC. A possible tolerated practice by authorities cannot excuse when the offender actually knew the conduct was unlawful.
