28 CFR 68.49 - Closing the record.
(a) When there is a hearing, the record shall be closed at the conclusion of the hearing unless the Administrative Law Judge directs otherwise.
(b) If any party waives a hearing, the record shall be closed on the date set by the Administrative Law Judge as the final date for the receipt of submissions of the parties to the matter.
(c) Once the record is closed, no additional evidence shall be accepted into the record except upon a showing that new and material evidence has become available which was not readily available prior to the closing of the record. However, the Administrative Law Judge shall make part of the record any motions for attorney's fees authorized by statutes, and any supporting documentation, any determinations thereon, and any approved correction to the transcript.
