The ABA Standing Committee on Ethics and Professional Responsibility has issued ABA Formal Ethics Opinion 522 - Lawyer’s Obligation to Disclose Information About Grounds for a Judge’s Disqualification. Its abstract reads as follows:
ABA Model Rule of Professional Conduct 8.4(d) prohibits a lawyer from engaging in conduct that is prejudicial to the administration of justice. When a lawyer in a proceeding possesses information that the lawyer knows is reasonably likely to give rise to a judicial disqualification obligation, Rule 8.4(d) requires the lawyer, as an officer of the court, to disclose that information to the tribunal. When the lawyer possesses the information only because it is “information relating to the representation of a client,” then the lawyer’s disclosure obligation is subject to the lawyer’s duty of confidentiality under Model Rule of Professional Conduct 1.6.
