For those who want to follow along at home:
4-8.3. Reporting Professional Misconduct
(a) A lawyer having knowledge that another lawyer has committed a violation of the Rules of Professional Conduct that raises a substantial question as to that lawyer's honesty, trustworthiness or fitness as a lawyer in other respects, shall inform the appropriate professional authority.
(b) A lawyer having knowledge that a judge has committed a violation of applicable rules of judicial conduct that raises a substantial question as to the judge's fitness for office shall inform the appropriate authority.
(c) This rule does not require disclosure of information otherwise protected by Rule 1.6.
4-1.6. Confidentiality of Information
(a) A lawyer shall not reveal information relating to representation of a client unless the client consents after consultation, except for disclosures that are impliedly authorized in order to carry out the representation, and except as stated in paragraph (b).
(b) A lawyer may reveal such information to the extent the lawyer reasonably believes necessary:
(1) to prevent the client from committing a criminal act that the lawyer believes is likely to result in imminent death or substantial bodily harm; or
(2) to establish a claim or defense on behalf of the lawyer in a controversy between the lawyer and the client, to establish a defense to a criminal charge or civil claim against the lawyer based upon conduct in which the client was involved, or to respond to allegations in any proceeding concerning the lawyer's representation of the client.
