Questão jurídica principal
Whether an assignment violating Art. 164 StGB is void under Art. 20 OR.
Decisão extraída
A violation of Art. 164 StGB does not automatically render the assignment void; voidness requires a rule or purpose in the criminal provision that clearly mandates civil invalidity, which is absent here.
Fundamentação extraída
The criminal provision protects creditors through criminal sanctions and supplements enforcement law, but its purpose is not to invalidate transactions ex officio or protect third parties. The system of the Debt Enforcement and Bankruptcy Act already provides targeted avoidance remedies with time limits, so importing automatic nullity would distort that system.
