A government agency shall not authorize, provide for or make a payment to a person under a contract containing the provision required by section 3734 (relating to contract provisions) unless the government agency is satisfied that the person has complied with the provision. The payment made to a person by a government agency which should not have been made shall be recoverable directly from the supplier of the motor vehicle who did not comply with section 3734 by the government agency or the Attorney General by appropriate legal action. Nothing in this section shall authorize any government agency to initiate a legal action independently of the Attorney General unless otherwise authorized under the act of October 15, 1980 (P.L.950, No.164), known as the Commonwealth Attorneys Act.
