Kernrechtsfrage
Whether the appellate court violated the right to be heard and evidentiary rules by refusing to re-examine witness A.
Extrahierter Entscheid
Yes. Because A.'s testimony was decisive and uncertain on the contested drug quantities, the court had to supplement the evidence.
Extrahierte Begründung
The existing file statements were incomplete and did not reliably resolve whether two additional 500 g sales occurred. The witness had given inconsistent and uncertain accounts, and no court had formed a direct impression of him.
