This bill proposes an amendment to the Impoundment Control Act of 1974 , introducing a significant new requirement for the Comptroller General. It mandates that the Comptroller General must obtain prior approval from Congress before initiating any civil action under the provisions of the Act. Specifically, the bill states that the Comptroller General may not bring a civil action unless Congress has first enacted a concurrent resolution explicitly authorizing that particular civil action. This measure aims to increase congressional oversight and control over the enforcement mechanisms related to impoundment, thereby altering the independent authority of the Comptroller General in these matters.
