16 C.F.R. § 3.39
(a) Where Commission complaint counsel desire the issuance of an order requiring a witness or deponent to testify or provide other information and granting immunity under 18 U.S.C. 6002, Directors and Assistant Directors of Bureaus and Regional Directors and Assistant Regional Directors of Commission Regional Offices who supervise complaint counsel responsible for presenting evidence in support of the complaint are authorized to determine:
(b) Requests by counsel other than Commission complaint counsel for an order requiring a witness to testify or provide other information and granting immunity under 18 U.S.C. 6002 may be made to the Administrative Law Judge and may be made ex parte. When such requests are made, the Administrative Law Judge is authorized to determine:
(2) That such individual has refused or is likely to refuse to testify or provide such information on the basis of his or her privilege against self-incrimination; and, upon making such determinations, to request, through the Commission's liaison officer, approval by the Attorney General for the issuance of an order requiring a witness to testify or provide other information and granting immunity; and, after the Attorney General (or his or her designee) has granted such approval, to issue such order when the witness or deponent has invoked his or her privilege against self-incrimination and it cannot be determined that such privilege was improperly invoked.
(18 U.S.C. 6002, 6004)
