54 STAT.] 76TH CONG. , 3D SESS.-CH. 640 -JULY 19, 1940 officer or employee is suspended from his office or employment during the pendency of such proceedings. A copy of such petition shall forthwith be served upon the Commission, and thereupon the Com- mission shall certify and file in the court a transcript of the record upon which the determination or the order complained of was made. The review by the court shall be on the record entire, including all of the evidence taken on the hearing, and shall extend to ques- tions of fact and questions of law. If application is made to the court for leave to adduce additional evidence, and it is shown to the satisfaction of the court that such additional evidence may materially affect the result of the proceedings and that there were reasonable grounds for failure to adduce such evidence in the hearing before the Commission, the court may direct such additional evidence to be taken before the Commission in such manner and upon such terms and conditions as to the court may seem proper. The Commission may modify its findings of fact or its determination or order by reason of the additional evidence so taken and shall file with the court such modified findings, determination, or order, and any such modified findings of fact, if supported by substantial evidence, shall be conclusive. The court shall affirm the Commission's determina- tion or order, or its modified determination or order, if the court determines that the same is in accordance with law. If the court determines that any such determination or order, or modified deter- mination or order, is not in accordance with law, the court shall remand the proceeding to the Commission with directions either to make such determination or order as the court shall determine to be in accordance with law or to take such further proceedings as, in the opinion of the court, the law requires. The judgment and decree of the court shall be final, subject to review by the appropriate circuit court of appeals as in other cases, and the judgment and decree of such circuit court of appeals shall be final, subject to review by the Supreme Court of the United States on certiorari or certification as provided in sections 239 and 240 of the Judicial Code, as amended (U. S . C., 1934 edition, title 28, secs. 346 and 347). If any provi- sion of this subsection is held to be invalid as applied to any party with respect to any determination or order of the Commission, such determination or order shall thereupon become final and effective as to such party in the same manner as if such provision had not been enacted. "(d) The Commission is authorized to adopt such reasonable pro- cedure and rules and regulations as it deems necessary to execute its functions under this section. The Civil Service Commission shall have power to require by subpena the attendance and testimony of witnesses and the production of all documentary evidence relating to any matter pending, as a result of this Act, before the Commission. Any member of the Commission may sign subpenas, and members of the Commission and its examiners when authorized by the Commis- sion may administer oaths and affirmations, examine witnesses, and receive evidence. Such attendance of witnesses and the production of such documentary evidence may be required from any place in the United States at any designated place of hearing. In case of dis- obedience to a snbpena, the Commission may invoke the aid of any court of the United States in requiring the attendance and testimony of witnesses and the production of documentary evidence. Any of the district courts of the United States within the jurisdiction of which such inquiry is carried on may, in case of contumacy or refusal to obey a subpena issued to any person, issue an order requiring such person to appear before the Commission, or to produce documentary evidence if so ordered, or to give evidence touching the matter in 193470--41-PT. -- 49 769 Transcriptof record.
