Iowa. R. App. P. 6.905
COMMENT: Former rule 6.905. The appendix process has been eliminated and has been replaced with the requirement to attach to the appellant's brief the orders and judgments being appealed as provided in rule 6.903(2)(b).
In exceptional cases, if a party believes that an appendix will assist the reviewing court, then that party may file a motion seeking leave of court to file an appendix. The motion must comply with rule 6.1002 and state the reasons leave of court is being requested. If granted, the requesting party may file an appendix with the brief.
