410.639—Subpenas.
When reasonably necessary for the full presentation of a case, an Administrative Law Judge (formerly called “hearing examiner”) or a member of the Appeals Council, may, either upon his own motion or upon the request of a party, issue subpenas for the attendance and testimony of witnesses and for the production of books, records, correspondence, papers, or other documents which are relevant and material to any matter in issue at the hearing. Parties who desire the issuance of a subpena shall, not less than 5 days prior to the time fixed for the hearing, file with the Administrative Law Judge or at a district office of the Administration a written request therefor, designating the witnesses or documents to be produced, and describing the address or location thereof with sufficient particularity to permit such witnesses or documents to be found. The request for a subpena shall state the pertinent facts which the party expects to establish by such witnesses or documents and whether such facts could be established by other evidence without the use of a subpena. Subpenas, as provided for above, shall be issued in the name of the Commissioner, and the Administration shall pay the cost of the issuance and the fees and mileage of any witness so subpenaed, as provided in section 205(d) of the Social Security Act.
