The Attorney General may issue subpoenas under this subsection (a). Whenever a subpoena is an express demand for any product of discovery, the Attorney General shall cause to be served, in any manner authorized by this Section, a copy of such demand upon the person from whom the discovery was obtained and shall notify the person to whom such demand is issued of the date on which such copy was served. Any information obtained by the Attorney General under this Section may be shared with any qui tam relator if the Attorney General determines it necessary as part of any Illinois False Claims Act investigation.
The certificate shall state that all of the documentary material required by the demand and in the possession, custody, or control of the person to whom the subpoena is directed has been produced and made available to the Attorney General.
If any interrogatory is objected to, the reasons for the objection shall be stated in the certificate instead of an answer. The certificate shall state that all information required by the subpoena and in the possession, custody, control, or knowledge of the person to whom the demand is directed has been submitted. To the extent that any information is not furnished, the information shall be identified and reasons set forth with particularity regarding the reasons why the information was not furnished.
