The Ohio Supreme Court's Board of Commissiones on Grievances & Discipline has issued a new Advisory Opinion (2013-3) on the use of judicial titles by former judges. This Syllabus of this Opinion states that
This new rule does not prevent lawyers and others who, out of respect, still want to use the title when speaking with a former Judge.Former judges may not use judicial titles while practicing law,
engaging in law-related or other business activities, working in government or
other public sector positions, or providing charity or community services.
Former judges serving as retired assigned, acting, and private judges may use
judicial titles in case-related entries, orders, decisions, and correspondence.
Former judges are permitted to describe past judicial service and experience in
communications such as biographical sketches, resumes, and curricula vitae.
This opinion only applies to the affirmative use of judicial titles by former judges,
and not the honorific use of judicial titles by others. Judges subject to the Code of
Judicial Conduct, however, must make reasonable efforts to ensure that former
judges involved in proceedings as lawyers, parties, or witnesses are not
addressed by judicial titles in the proceedings.
