AMERICAN BAR ASSOCIATION STANDING COMMITTEE ON ETHICS AND PROFESSIONAL RESPONSIBILITY
Formal Opinion 09-454 July 8, 2009
Prosecutor’s Duty to Disclose Evidence and Information Favorable to the Defense Rule 3.8(d) of the Model Rules of Professional Conduct requires a prosecutor to “make timely disclosure to the defense.
This ethical opinion reinforces the rule that the prosecutors obligation to disclose certain types of information to the defense is self-executing – that is Brady, Kyles, Giglio, and similar material must be disclosed even though the defense has not submitted a formal discovery request — and goes beyond what the R.C.M. and appellate decisions say. So, for example, a prosecutor has an ethical duty to disclose certain information she learns during pretrial interviews of prosecution witnesses.
