Rule text
The neutral, before the conclusion of the hearing, or the commission, before its determination, may allow or require amendments of the complaint or the answer. The complaint may be amended to conform to the proofs or to set forth additional facts, whether occurring before or after the commencement of the hearing. If an amendment is made, the respondent must be given reasonable time to answer the amendment and to prepare and present a defense against the matters charged in the amendment. A "28-day letter" is not required to amend a complaint.
