15 CFR 904.207 - Amendment of pleading or record.
(a) A party may amend its pleading as a matter of course at least 20 days prior to a hearing. Within 20 days prior to a hearing a party may amend its pleading only by leave of the Judge or by written consent of the adverse party; leave shall be freely given when justice so requires. A party shall plead in response to an amended pleading within the time remaining for response to the original pleading or within 10 days after service of the amended pleading, whichever period is longer, unless the Judge otherwise orders.
(b) The Judge, upon his or her own initiative or upon application by a party, may order a party to make a more definite statement of any pleading.
(c) Harmless errors in pleadings or elsewhere in the record may be corrected (by deletion or substitution of words or figures), and broad discretion will be exercised by the Judge in permitting such corrections.
