FAR 1.705 Supersession and modification.

The codified text (eCFR, as of 2026-10-02). Under the Revolutionary FAR Overhaul ↗, agencies follow class deviations with new text for many parts while the formal rules go through the Federal Register: check the solicitation and your contract's clauses, which rule.

In plain English

This section explains what happens when a Determination and Findings (D&F) is replaced or changed. If a D&F is superseded, actions already taken under the original D&F remain valid. Also, if a modified D&F still supports the contract action, the contracting officer does not have to cancel the solicitation.

Applies to: Contracting officers and actions taken under a D&F
