Key legal question
Whether the complainants had standing to appeal the refusal to open disciplinary proceedings against the advocate.
Extracted holding
They lacked standing because attorney disciplinary proceedings protect the public interest in proper professional conduct, not the complainants' individual interests.
Extracted reasoning
An informant in bar disciplinary matters generally has no protected interest under Art. 89 BGG in the opening or conduct of proceedings, and therefore cannot seek judicial review of a refusal to initiate them.
