410.664—Evidence admissible on review.
(a) Admissibility of additional evidence.
Evidence in addition to that introduced at the hearing before the presiding officer, or documents before the presiding officer where such hearing was waived (see § 410.647 ), may not be admitted except where it appears to the Appeals Council that such evidence is relevant and material to an issue before it and thus may affect its decision.
(b) Receipt of evidence by Presiding Officer.
Where the Appeals Council determines that additional evidence is needed for a sound decision, it will remand the case to a presiding officer for receipt of the evidence, further proceedings, and a new decision, except where the Appeals Council can obtain the evidence more expeditiously and the rights of the claimant will not be adversely affected.
(c) Receipt of evidence by Appeals Council.
Where the Appeals Council obtains the evidence itself, before such evidence is admitted into the record, notice that evidence will be received with respect to certain issues shall be mailed to the parties, unless such notice is waived, at their last known addresses, and the parties shall be given a reasonable opportunity to comment thereon and to present evidence which is relevant and material to such issues.
(d) Copies of evidence.
When additional evidence is presented to a presiding officer or to the Appeals Council, a transcript or a condensed statement of such evidence shall be made available to any party upon request, upon payment of the cost, or if such cost is not readily determinable, the estimated amount thereof, unless, for good cause shown, such payment is waived.
