This legislation establishes stringent limitations on the management of discretionary appropriations for the National Institutes of Health (NIH). Its primary purpose is to prevent the impoundment, transfer, or reprogramming of these crucial funds. Under this Act, any such action would only be permitted if new, specific statutory authority is enacted into law after its effective date, explicitly referencing this Act. This provision effectively overrides other existing laws, including the Impoundment Control Act of 1974, to ensure the stability of NIH funding. Additionally, the Secretary of Health and Human Services is mandated to provide annual certification to relevant Congressional committees, confirming compliance with these new requirements.
