The main purpose of this legislation is to amend an existing law related to the Congressional Budget Act of 1974. Specifically, it aims to classify any provisions that lead to the sale, disposal, or transfer of federal lands as "extraneous" under a rule known as the Byrd Rule. This change is intended to ensure that such provisions cannot be included in budget reconciliation bills, which are designed to expedite the legislative process for budget-related measures. Key provisions of this legislation include a specific amendment to Section 313 of the Congressional Budget Act.
