Human research which is subject to policies and regulations for the protection of human subjects promulgated by any agency of the federal government shall be exempt from the provisions of this chapter. In lieu of promulgating regulations pursuant to the requirements of this chapter, an institution or agency may comply with this chapter by promulgating regulations under the provisions of the Administrative Process Act (§ 2.2-4000 et seq.) governing human research projects which incorporate, explicitly or by reference, federal policies and regulations for the protection of human subjects. However, in the case of projects which are not required, by reason of their nature, the source of their funding, or the lack thereof, to comply with federal policies and regulations, the institution or agency may enforce compliance by filing a petition for an injunction in the appropriate circuit court. This section shall not preclude any other enforcement action available to the institution or agency.
