Key legal question
Whether the conduct amounted to qualified robbery under Art. 140 Ziff. 4 StGB by placing the victim in immediate life danger.
Extracted holding
Yes. Holding the victim in a chokehold while pressing a sharp knife to her neck created an immediate, highly probable danger to life.
Extracted reasoning
Life danger must be concrete and immediate, assessed objectively; the victim's subjective fear is irrelevant. Under the given circumstances, even a slight movement could have caused a fatal injury.
