I think the closing of the EC letter has an interesting detail - “please be advised that you are prohibited from using any confidential information, as that term is defined in Section 8-13-100(7), in furtherance of your own economic interest.”
"Confidential information" means information, whether transmitted orally or in writing, which is obtained by reason of the public position or office held and is of such nature that it is not, at the time of transmission, a matter of public record or public knowledge.

in just one of several parts of book she writes about a conversation she heard while being present in Judge’s chambers. I am not sure if that falls within the “confidential information” as the public would not normally know what happened in there, and her position allowed her to be present for that. In my amateur opinion, including details like that in a book being sold (“own economic interest”) sadly seems to go against what the Ethics Commission is mentioning. That information shared, I think, was only possible because of her public position; going by the very definition written in the law but JMOO.
