Question juridique clé
Whether the robbery offenses were correctly qualified as gang robbery under Art. 140 Ziff. 3 StGB.
Solution extraite
The gang qualification was insufficiently established on the concrete facts; the lower court could not infer the required common intent merely from repeated similar offenses in close time and place.
Motifs extraits
Gang membership requires an expressly or impliedly manifested will to cooperate in the commission of several, still undefined offenses. The court found no concrete circumstances showing such a shared plan; similarity of method, repeated offenses, and arrest ending the conduct did not suffice.
