Questione giuridica chiave
Whether the knife attack was justified as self-defence under Art. 15 StGB
Decisione estratta
The use of the knife was not proportionate; at most it was an excessive self-defence response.
Motivazione estratta
A single unexpected head-butt did not justify a wounding knife stab to the abdomen. In a dangerous-weapon defense, warning or a milder use targeting less vulnerable parts should have been attempted first.
