Iowa. R. Civ. P. 1.904
COMMENT: Rules 1.904(3) and 1.904(4) supersede prior case law that held a timely rule 1.904(2) motion must also have been "proper" to extend the time for appeal. See, e.g., Hedlund v. State, 875 N.W.2d 720, 725 (Iowa 2016). To obviate controversies over whether a rule 1.904(2) motion tolls the time for appeal, the rule authorizes any timely rule 1.904(2) motion to extend the appeal deadline, subject to one exception in rule 1.904(4).
Under rule 1.904, the timely filing of a rule 1.904(2) motion extends the deadline for filing a notice of appeal or an application for interlocutory appeal. See Iowa R. App. P. 6.101(1)(b) & 6.104(1)(b)(2). However, the rule does not address whether a rule 1.904(2) motion preserves error for purposes of appeal as to evidence or arguments raised for the first time in that motion. See, e.g., Tenney v. Atlantic Associates, 594 N.W.2d 11, 14 (Iowa 1999). The rule also is not intended to affect prior case law concerning a court's inherent authority to reconsider. See Iowa Elec. Light & Power Co. v. Lagle, 430 N.W.2d 393, 395-96 (Iowa 1988).
