The United States General Services Administration (GSA) is issuing a final rule amending the Federal Management Regulation (FMR). This amendment executes changes that include the removal, addition, and revision of definitions, the elimination of gender pronouns, the simplification of requirements, the alteration of statutory references, and the clarification of GSA’s role in adjudicating disputes arising from audits of transportation bills. These adjustments are necessary to furnish accurate guidance for agencies, facilitate proper management and compliance with transportation invoice payment and audit obligations.
