Section 263.20 - Amended pleadings(a)Amendments. The notice or answer may be amended or supplemented at any stage of the proceeding. The respondent must answer an amended notice within the time remaining for the respondent's answer to the original notice, or within ten days after service of the amended notice, whichever period is longer, unless the Board or administrative law judge orders otherwise for good cause.(b)Amendments to conform to the evidence. When issues not raised in the notice or answer are tried at the hearing by express or implied consent of the parties, they will be treated in all respects as if they had been raised in the notice or answer, and no formal amendments are required. If evidence is objected to at the hearing on the ground that it is not within the issues raised by the notice or answer, the administrative law judge may admit the evidence when admission is likely to assist in adjudicating the merits of the action and the objecting party fails to satisfy the administrative law judge that the admission of such evidence would unfairly prejudice that party's action or defense upon the merits. The administrative law judge may grant a continuance to enable the objecting party to meet such evidence.
