Here's one way:
I sincerely and profusely apologize to you and your family for the email I forwarded. I accept full responsibility; I have no one to blame but myself. I can assure you that such action on my part will never happen again. I have requested that the Judicial Council of the 9th Circuit review this matter. Honestly, I don't know what else I can do. Please forgive me and, again, my most sincere apology.
Here's the ABA Journal report on the story, and here's the National Law Journal story on the ethical implications of the situation.
