Key legal question
Whether the complainant is entitled to lodge a disciplinary complaint under § 15(1) AnwG despite not being the lawyer's client
Extracted holding
Yes. A person affected by a lawyer's professional conduct has standing; the complainant was affected by disclosure of information learned in the course of the lawyer's work.
Extracted reasoning
Standing under § 15(1) AnwG extends to anyone affected by the lawyer's professional conduct. The decisive criterion for attorney-client secrecy is the connection with professional activity, not only formal client status. The disputed information was obtained in the course of the lawyer's work in the spouses' divorce proceedings and its disclosure directly affected the complainant.
