Evidentiary record
(d) Evidentiary record. The evidentiary record before the agency of original jurisdiction for an initial or supplemental claim includes all evidence received by VA before VA issues notice of a decision on the claim. Once the agency of original jurisdiction issues notice of a decision on a claim, the evidentiary record closes as described in 3.103(c)(2) and VA no longer has a duty to assist in gathering evidence under 3.159. (See 3.155(b), submission of evidence).
