The purpose of this legislative text is to change how the Comptroller General can take legal action under the Impoundment Control Act of 1974. The main objective is to ensure that before the Comptroller General can pursue any civil action related to the impoundment of federal funds, they must first receive approval from Congress. The key provision of this legislation is the requirement for prior Congressional approval. Specifically, it states that the Comptroller General cannot initiate a civil action unless Congress has passed a concurrent resolution that authorizes such action.
