Questão jurídica principal
Whether the defendant remained the sole debtor of the exchange debts after the business transfer.
Decisão extraída
The defendant remained the sole debtor; the alleged transfer of the debt to his son was not accepted.
Fundamentação extraída
The court relied on the binding findings and the prior civil judgment confirming that the defendant had acted in his own name and remained liable; the asserted transfer conflicted with the Supreme Court's civil decision.
