The regulations in this part are issued in compliance with the requirements imposed by the provisions of section 4(c) of the Antitrust Civil Process Act, as amended (15 U.S.C. 1313(c)). The terms used in this part shall be deemed to have the same meaning as similar terms used in that Act.

(a) Upon taking physical possession of documentary material, answers to interrogatories, or transcripts of oral testimony delivered pursuant to a civil investigative demand issued under section 3(a) of the Act, the antitrust document custodian designated pursuant to section 4(a) of the Act (subject to the general supervision of the Assistant Attorney General in charge of the Antitrust Division), shall, unless otherwise directed by a court of competent jurisdiction, select, from time to time, from among such documentary material, answers to interrogatories or transcripts of oral testimony, the documentary material, answers to interrogatories or transcripts of oral testimony the copying of which the custodian deems necessary or appropriate for the official use of the Department of Justice, and shall determine, from time to time, the number of copies of any such documentary material, answers to interrogatories or transcripts of oral testimony that are to be reproduced pursuant to the Act.

(b) Copies of documentary material, answers to interrogatories, or transcripts of oral testimony in the physical possession of the custodian pursuant to a civil investigative demand may be reproduced by or under the authority of any officer, employee, or agent of the Department of Justice designated by the custodian. Documentary material for which a civil investigative demand has been issued but which is still in the physical possession of the person upon whom the demand has been served may, by agreement between such person and the custodian, be reproduced by such person, in which case the custodian may require that the copies so produced be duly certified as true copies of the original of the material involved.

Documentary material, answers to interrogatories, or transcripts of oral testimony produced pursuant to the Act, while in the custody of the custodian, shall be for the official use of officers, employees, and agents of the Department of Justice in accordance with the Act. Upon reasonable notice to the custodian—

(a) Such documentary material or answers to interrogatories shall be made available for examination by the person who produced such documentary material or answers to interrogatories, or by any duly authorized representative of such person; and

(b) Such transcripts of oral testimony shall be made available for examination by the person who produced such testimony, or by such person's counsel, during regular office hours established for the Department of Justice. Examination of such documentary material, answers to interrogatories, or transcripts of oral testimony at other times may be authorized by the Assistant Attorney General or the custodian.

Deputy custodians may perform such of the duties assigned to the custodian as may be authorized or required by the Assistant Attorney General.
