Iowa. Code. Jud. Cond. 51:2.12
Comment
[1] A judge is responsible for his or her own conduct and for the conduct of others, such as staff, when those persons are acting at the judge's direction or control. A judge may not direct court personnel to engage in conduct on the judge's behalf or as the judge's representative when such conduct would violate the Iowa Code of Judicial Conduct if undertaken by the judge.
[2] Public confidence in the judicial system depends upon timely justice. To promote the efficient administration of justice, a judge with supervisory authority must take the steps needed to ensure that judges under his or her supervision administer their workloads promptly.
