Questão jurídica principal
Whether the trial court's fact-finding was arbitrary because it failed to clarify the weight of the transported pigs
Decisão extraída
Yes. The decisive fact was left unresolved even though it could have been clarified without difficulty; the acquittal therefore rested on an incomplete investigation and arbitrary fact-finding.
Fundamentação extraída
If the investigation leaves a decisive evidentiary gap that further inquiries would obviously fill, the court must take those additional steps. Otherwise, relying on in dubio pro reo to reach a favorable result for the accused is arbitrary.
