Key legal question
Whether the complainant had standing to challenge the refusal to open disciplinary proceedings against the lawyer.
Extracted holding
The complainant had no protected own interest and therefore could not attack the non-opening of disciplinary proceedings.
Extracted reasoning
Lawyer-discipline serves the public interest in proper professional conduct, not private interests of the complainant; therefore no standing under Art. 89 BGG and no judicial-review entitlement under Art. 29a BV.
