Iowa R. App. P. 6.602
If any party to an appeal is aggrieved by the clerk of district court's approval of, or refusal to approve, a supersedeas bond tendered by the appellant, the party may apply to the district court, on at least 3 days' notice to the adverse party, to review the clerk's action. Pending such hearing, the district court may recall or stay all proceedings under the order or judgment appealed from. On such hearing, the district court will determine the sufficiency of the bond, and if the clerk has not approved the bond, the district court will, by order, fix its conditions and determine the sufficiency of the security; or if the district court determines that a bond approved by the clerk is insufficient in security or defective in form, it will discharge the bond and fix a time for filing a new one.
