Example: During the course of the representation, counsel learns that his client's marriage is in desperate straits, and that the couple is experiencing sexual problems. Without discussing this matter with anyone else, counsel uses the information to embark on a sexual relationship with the client's wife. He has thereby breached the duty of confidentiality.I should've figured I wouldn't have written "tremendous example!" un-ironically.
As if that weren't "tremendous!" enough, the example concluded with a citation. If you have access to QuickLaw, I recommend you search "54 O.R. (2d) 663" and read the head-note.
