Kernrechtsfrage
Whether the refusal to hear witness Z. violated the defendant's right to be heard and defense rights
Extrahierter Entscheid
The refusal was lawful because the court could, without arbitrariness, conclude that further testimony would not change its view of the established facts.
Extrahierte Begründung
The defendant had already admitted hitting the victim and the essential sequence was undisputed; the legal characterization of his intervention did not depend on the proposed witness.
