(a) Authority to execute commission. Under the provisions of section 1 of the act of June 25, 1948, as amended (sec. 1, 62 Stat. 834, sec. 53, 63 Stat. 96; 18 U.S.C. 3492), a diplomatic or consular officer may be commissioned by an United States court to take the testimony of a witness in a foreign country either on oral or written interrogatories, or partly on oral and partly on written interrogatories, for the purpose of determining the genuineness of any foreign document (any book, paper, statement, record, account, writing, or other document, or any portion thereof, of whatever character and in whatever form, as well as any copy thereof equally with the original, which is not in the United States) which it is desired to introduce in evidence in any criminal action or proceeding in any United States court under the provisions of section 1 of the act of June 25, 1948 (sec. 1, 62 Stat. 945; 28 U.S.C. 1732). Such testimony may also be taken to determine whether the foreign document was made in the regular course of business and whether it was the regular course of business to make such document. The term “business” includes business, profession, occupation, and calling of every kind. (Sec. 1, 62 Stat. 945, 28 U.S.C. 1732.)

(b) Disqualification to execute commission. Any diplomatic or consular officer to whom a commission is addressed to take testimony, who is interested in the outcome of the criminal action or proceeding in which the foreign documents in question are intended to be used or who has participated in the prosecution of such action or proceeding, whether by investigations, preparation of evidence, or otherwise, may be disqualified on his own motion or on that of the United States or any other party to such criminal action or proceeding made to the court from which the commission issued at any time prior to the execution thereof. If, after notice and hearing, the court grants the motion, it will instruct the diplomatic or consular officer thus disqualified to send the commission to any other diplomatic or consular officer of the United States named by the court, and such other officer should execute the commission according to its terms and will for all purposes be deemed the officer to whom the commission is addressed. (Section 1, 62 Stat. 834, sec. 53, 63 Stat. 96; 18 U.S.C. 3492.)

(c) Execution and return of commission. (1) Commissions issued in criminal cases under the authority of the act of June 25, 1948, as amended, to take testimony in connection with foreign documents should be executed and returned by officers of the Foreign Service in accordance with section 1 of that act, as amended (sec. l, 62 Stat. 835; 18 U.S.C. 3493,3494,and. For details not covered by such section or by special instructions, officers of the Foreign Service should be guided by such instructions as may be issued by the Department of State in connection with the taking of depositions generally. (See §§ 92.55 to 92.64.)

(2) Section 1 of the act of June 25, 1948 (sec. 1, 62 Stat. 835; 18 U.S.C. 3493) provides that every person whose testimony is taken should be cautioned and sworn to testify the whole truth and should be carefully examined. The testimony should be reduced to writing or typewriting by the consular officer, or by some person under his personal supervision, or by the witness himself in the presence of the consular officer, and by no other person. After it has been reduced to writing or typewriting, the testimony must be signed by the witness. Every foreign document with respect to which testimony is taken must be annexed to such testimony and must be signed by each witness who appears for the purpose of establishing the genuineness of such document.

(3) When counsel for all of the parties attend the examination of any witness whose testimony will be taken on written interrogatories, they may consent that oral interrogatories, in addition to those accompanying the commission, be put to the witness. The consular officer taking the testimony should require an interpreter to be present when his services are needed or are requested by any party or his attorney. (Section 1, 62 Stat. 835, 18 U.S.C. 3493.)

(4) Section 1 of the act of June 25, 1948 (sec. 1, 62 Stat. 835; 18 U.S.C. 3494) provides that the consular officer, who executes any commission authorized under the same section, as amended (sec. 1, 62 Stat. 834, sec. 53, 63 Stat. 96; 18 U.S.C. 3492) and who is satisfied, upon all the testimony taken, that a foreign document is genuine, should certify such document to be genuine under the seal of his office. This certification must include a statement that the officer is not subject to disqualification under the provisions of section 1 of the act of June 25, 1948, as amended (sec. 1, 62 Stat. 834, sec. 53, 63 Stat. 96; 18 U.S.C. 3492). For purposes of assessment of fees, the issuance of this certificate shall be regarded as a part of the consular service of executing the commission, and no separate fee shall be charged for the certificate.

(5) The consular officer should then forward such foreign documents, together with the record of all testimony taken and the commission which has been executed, to the Department of State for transmission to the clerk of the court from which the commission issued. (Section 1, 62 Stat. 835; 18 U.S.C. 3494.) (See § 92.64 regarding the filing of depositions generally.)
