Key legal question
Whether attorney-client confidentiality applies vis-à-vis the supervisory authority in pending disciplinary proceedings without formal release.
Extracted holding
The parties are treated as released from confidentiality in disciplinary proceedings before the supervisory authority; no formal waiver procedure is required.
Extracted reasoning
Established practice accepts that, in disciplinary proceedings, confidentiality does not operate against the supervisory authority. The cited Zürich practice confirms that the lawyer's privilege is not applicable before the supervisory commission in such proceedings.
