Iowa. R. Crim. P. 2.11
Comment: Former rule 2.11(9) authorized a "motion for change of judge" to be "verified on information and belief by the movant." References to the motion of change of judge have been deleted from revised rule 2.11 because they have been superseded by other sources of law relating to recusal and disqualification. See, e.g., Iowa Ct. R. 51:2.11. While a litigant should certainly move for disqualification of a judge when a legal ground for doing so arises, that is not the only way for disqualification to occur.
Comment: Rule 2.11(12)(c) is intended to codify the principle set forth in State v. Rodriguez, 807 N.W.2d 35, 38-39 (Iowa 2011), including the safeguards described therein.
