Greenberg Traurig – On June 23, 2026, the Federal Acquisition Regulation (FAR) Council initiated formal notice-and-comment rulemaking for the Revolutionary FAR Overhaul (RFO) and issued the first four proposed rules. As part of the anticipated changes to FAR Part 40, the FAR Council has included a revised FAR Controlled Unclassified Information (CUI) Rule. The proposed rule reopened the public comment period, giving contractors and other interested parties another opportunity to weigh in on requirements that might affect how CUI is handled.
