Iowa Code § 468.86: Petition — docket fee — waiver — dismissal.

Within twenty days after perfection of the appeal the appellant shall file a petition setting forth the order or final action of the board appealed from and the grounds of the appellant’s objections and the appellant’s complaint, with a copy of the appellant’s claim for damages or objections filed with the auditor. The appellant shall pay to the clerk the filing fee as provided by law in other cases. A failure to pay the filing fee or to file such petition shall be deemed a waiver of the appeal and in such case the court shall dismiss the same.
