Iowa Admin. Code r. 621-2.5
Hearings or proceedings on any matter may be continued by order of the board or an administrative law judge, with the reasons therefor set out in said order, and notice thereof to all parties. Parties may, upon written application to the board prior to commencement of the hearing or other proceeding, or oral application to the administrative law judge during the hearing, but not ex parte, request a continuance. A continuance may be allowed for any cause not growing out of the fault or negligence of the applicant, which satisfies the board or administrative law judge that a proper decision or result will be more nearly obtained by granting a continuance. The continuance may also be granted if agreed to by all parties and approved by the board or administrative law judge.
