Iowa. Code. Jud. Cond. 51:2.11
Court Order April 30, 2010, effective May 3, 2010.
Comment  Under this rule, a judge is disqualified whenever the judge's impartiality might reasonably be questioned, regardless of whether any of the specific provisions of paragraphs (A)(1) through (6) apply. The term "recusal" is used interchangeably with the term "disqualification."  A judge's obligation not to hear or decide matters in which disqualification is required applies regardless of whether a motion to disqualify is filed.  The rule of necessity may override the rule of disqualification. For example, a judge might be required to participate in judicial review of a judicial salary statute, or might be the only judge available in a matter requiring immediate judicial action, such as a hearing on probable cause or a temporary restraining order. In matters that require immediate action, the judge must disclose on the record the basis for possible disqualification and make reasonable efforts to transfer the matter to another judge as soon as practicable.  The fact that a lawyer in a proceeding is affiliated with a law firm with which a relative of the judge is affiliated does not itself disqualify the judge. If, however, the judge's impartiality might reasonably be questioned under paragraph (A), or the relative is known by the judge to have an interest in the law firm that could be substantially affected by the proceeding under paragraph (A)(2)(c), the judge's disqualification is required.  A judge should disclose on the record information that the judge believes the parties or their lawyers might reasonably consider relevant to a possible motion for disqualification, even if the judge believes there is no basis for disqualification.  "Economic interest," as set forth in the terminology section, means ownership of more than a de minimis legal or equitable interest. Except for situations in which a judge participates in the management of such a legal or equitable interest, or the interest could be substantially affected by the outcome of a proceeding before a judge, it does not include: (1) an interest in the individual holdings within a mutual or common investment fund; (2) an interest in securities held by an educational, religious, charitable, fraternal, or civic organization in which the judge or the judge's spouse, domestic partner, parent, or child serves as a director, officer, advisor, or other participant; (3) a deposit in a financial institution or deposits or proprietary interests the judge may maintain as a member of a mutual savings association or credit union, or similar proprietary interests; or (4) an interest in the issuer of government securities held by the judge.
