20 CFR 402.150 - Release of records.
(a) Records previously released. If we have released a record, or a part of a record, to others in the past, we will ordinarily release it to you also. However, we will not release it to you if a statute forbids this disclosure, and we will not necessarily release it to you if an exemption applies in your situation and it did not apply, or applied differently, in the previous situation(s) or if the previous release was unauthorized. See § 402.45(d) regarding records in electronic reading rooms.
(b) Poor copy. If we cannot make a legible copy of a record to be released, we do not attempt to reconstruct it. Instead, we furnish the best copy possible and note its poor quality in our reply.
