5 CFR §297.303

1. (a)The amendment procedures are not intended to allow a challenge to material that records an event that actually occurred nor are they designed to permit a collateral attack upon that which has been or could have been the subject of a judicial, quasi-judicial, or administrative proceeding. The amendment procedures are also not designed to change opinions in records pertaining to the individual.
2. (b)The amendment procedures apply to situations when an occurrence that is documented was challenged through an established judicial, quasi-judicial, or administrative procedure and found to be inaccurately described; when the document is not identical to the individual's copy; or when the document is not created in accordance with the applicable recordkeeping requirements. (For example, the amendment provisions are not designed to allow a challenge to the merits of an agency adverse action that is documented in an individual's Official Personnel Folder.)
