Under 2200.105(a), what is prohibited by the rule on ex parte communications?
The rule prohibits any ex parte communication about the merits of a pending case between Commissioners, Judges, or employees or agents who are employed in the decisional process and any party, intervenor, representative, or other interested person, except as permitted by law or 2200.120. This means you may not privately discuss the substance of a case with a decisionmaker who is involved in deciding that case. See 2200.105(a).
