Kernrechtsfrage
Whether the unsealing of the bank detail records was barred by attorney-client privilege or bank secrecy
Extrahierter Entscheid
No absolute barrier existed: the lawyer could not invoke privilege for his own account records, and bank secrecy cannot prevent lawful criminal investigation measures.
Extrahierte Begründung
Art. 264 StPO protects certain attorney communications, but not where the lawyer is himself accused in the same matter. The appellant also lacked standing to assert third parties' secrecy interests in his own name.
