Iowa. Code. Jud. Cond. 51:2.9
Comment
[1] To the extent reasonably possible, all parties or their lawyers shall be included in communications with a judge. See, e.g., IowaR. Civ. P. 1.1507.
[2] Whenever the presence of a party or notice to a party is required by this rule, it is the party's lawyer or, if the party is unrepresented, the party who is to be present or to whom notice is to be given.
[3] The proscription against communications concerning a proceeding includes communications with lawyers, law teachers, and other persons who are not participants in the proceeding, except to the limited extent permitted by this rule.
[4] A judge may initiate, permit, or consider ex parte communications expressly authorized by law, such as when serving on therapeutic or problem-solving courts, mental health courts, or drug courts. In this capacity, judges may assume a more interactive role with parties, treatment providers, probation officers, social workers, and others.
[5] A judge may consult with other judges on pending matters, but must avoid ex parte discussions of a case with judges who have previously been disqualified from hearing the matter and with judges who have appellate jurisdiction over the matter.
[6] The prohibition against a judge investigating the facts in a matter extends to information available in all mediums, including electronic.
[7] A judge may consult ethics advisory committees, outside counsel, or legal experts concerning the judge's compliance with the Iowa Code of Judicial Conduct. Such consultations are not subject to the restrictions of paragraph (A)(2).
[8] Parties frequently present ex parte requests to a judge for routine scheduling matters. Iowa Rule of Civil Procedure 1.453 requires the clerk to provide notice of all orders entered by the court. A notice of orders entered in routine scheduling matters provided by the clerk satisfies the judge's obligation under paragraph (A)(1)(b).
