If such demand is for the production of documentary material, the demand shall (i) describe each class of documentary material to be produced with such definiteness and certainty as to permit such material to be fairly identified; (ii) prescribe a return date for each such class that will provide a reasonable period of time within which the material so demanded may be assembled and made available for inspection and copying; and (iii) identify the false claims law investigator to whom such material shall be made available.

If such demand is for answers to written interrogatories, the demand shall (i) set forth with specificity the written interrogatories to be answered; (ii) prescribe dates at which time answers to written interrogatories shall be submitted; and (iii) identify the false claims law investigator to whom such answers shall be submitted.

If such demand is for the giving of oral testimony, the demand shall (i) prescribe a date, time, and place at which oral testimony shall be commenced; (ii) identify a false claims law investigator who shall conduct the examination and the custodian to whom the transcript of such examination shall be submitted; (iii) specify that such attendance and testimony are necessary to the conduct of the investigation; (iv) notify the person receiving the demand of the right to be accompanied by an attorney and any other representative; and (v) describe the general purpose for which the demand is being issued and the general nature of the testimony, including the primary areas of inquiry that will be taken pursuant to the demand.

Any civil investigative demand that is an express demand for any product of discovery shall not be returned or returnable until twenty-one days after a copy of such demand has been served upon the person from whom the discovery was obtained.

The date prescribed for the commencement of oral testimony pursuant to a civil investigative demand issued under this article shall be a date that is not less than seven days after the date on which the demand is received, unless the Attorney General determines that exceptional circumstances are present that warrant the commencement of such testimony within a lesser period of time.

The Attorney General shall not authorize the issuance of more than one civil investigative demand for oral testimony by the same person unless the person requests otherwise or unless the Attorney General, after investigation, notifies that person in writing that an additional demand for oral testimony is necessary.
