Mich. R. Prof'l. Cond. 3.6
Comment:
It is difficult to strike a balance between protecting the right to a fair trial and safeguarding the right of free expression. Preserving the right to a fair trial necessarily entails some curtailment of the information that may be disseminated about a party before trial, particularly where trial by jury is involved. If there were no such limits, the result would be the practical nullification of the protective effect of the rules of forensic decorum and the exclusionary rules of evidence. On the other hand, there are vital social interests served by the free dissemination of information about events having legal consequences and about legal proceedings themselves. The public has a right to know about threats to its safety and measures aimed at assuring its security. It also has a legitimate interest in the conduct of judicial proceedings, particularly in matters of general public concern. Furthermore, the subject matter of legal proceedings is often of direct significance in debate and deliberation over questions of public policy.
Special rules of confidentiality may validly govern juvenile, domestic relations, and mental disability proceedings, in addition to other types of litigation. Rule 3.4(c) requires compliance with such rules.
Rule 3.6 sets forth a basic general prohibition against a lawyer's making statements that the lawyer knows or should know will have a substantial likelihood of materially prejudicing an adjudicative proceeding. Recognizing that the public value of informed commentary is great and the likelihood of prejudice to a proceeding by the commentary of a lawyer who is not involved in the proceeding is small, the rule applies only to lawyers who are, or who have been, involved in the investigation or litigation of a case, and their associates.
See Rule 3.8(e) for additional duties of prosecutors in connection with extrajudicial statements about criminal proceedings.
