At any time during the proceedings, informal disposition may be made of any contested case by stipulation of the parties, agreed settlement, consent order, or default. No stipulation or agreed settlement between the parties shall be enforced unless it shall have been reduced to writing and signed by parties and made part of the record, or unless it shall have been dictated into the record by them during the course of a hearing or incorporated in an order bearing their written consent.
