Question juridique clé
Whether the limited waiver from lawyer-client privilege for the lawyer's defense was lawful.
Solution extraite
The limited waiver was lawful because the client had already initiated criminal proceedings against the lawyer and thereby waived confidentiality to the extent necessary for the lawyer's defense.
Motifs extraits
An attorney may be released from secrecy when his own interests in defending himself outweigh the client's confidentiality interest. Refusing the waiver here would be abusive, and the waiver was limited to what was necessary for the lawyer's defense.
