Kernrechtsfrage
Whether the appellant acted as a coauthor rather than merely as an accomplice
Extrahierter Entscheid
He was a coauthor because he participated in the planning and execution of the robbery, aligned himself with the criminal decision without reserve, and received a share of the booty.
Extrahierte Begründung
Coauthorship requires decisive participation in the decision, organization, or execution and a role that is not merely secondary. The appellant joined all preparations, accepted a diversion role, and obtained a percentage of the proceeds rather than fixed payment.
