Any member of the Commission or any employee of the Commission, designated in writing for the purpose by the Chief Commissioner, may administer oaths and examine witnesses. Any member of the Commission may require by subpena (1) the attend- ance and testimony of witnesses, and the production of all necessary books, papers, documents, correspondence, and other evidence, from any place in the United States or Alaska at any designated place of hearing; or (2) the taking of depositions before any designated individual competent to administer oaths under the laws of the United States or of any State or Territory. In the case of a deposi- tion, the testimony shall be reduced to writing by the individual taking the deposition or under his direction and shall be subscribed by the deponent. In taking testimony, opportunity shall be given for cross-examination, under such regulations as the Commission may prescribe. Witnesses subpenaed to testify or whose depositions are taken pursuant to this Act, and the officers or persons taking the same, shall severally be entitled to the same fees and mileage as are paid for like services in the courts of the United States. FINAL DETERMINATION SEC. 19. The final determination of the Commission shall be in writing, shall be filed with its clerk, and shall include (1) its find- ings of the facts upon which its conclusions are based; (2) a state- ment (a) whether there are any just grounds for relief of the claimant and, if so, the amount thereof; (b) whether there are any allowable offsets, counterclaims, or other deductions, and, if so, the amount thereof; and (3) a statement of its reasons for its findings and conclusions. REVIEW BY COURT OF CLAIMS SEC. 20. (a) In considering any claim the Commission at any time may certify to the Court of Claims any definite and distinct questions of law concerning which instructions are desired for the proper disposition of the claim; and thereupon the Court of Claims may give appropriate instructions on the questions certified and transmit the same to the Commission for its guidance in the further consideration of the claim. (b) When the final determination of the Commission has been filed with the clerk of said Commission the clerk shall give notice of the filing of such determination to the parties to the proceeding in manner and form as directed by the Commission. At any time within three months from the date of the filing of the determination of the Com- mission with the clerk either party may appeal from the determination of the Commission to the Court of Claims, which Court shall have exclusive jurisdiction to affirm, modify, or set aside such final deter- mination. On said appeal the Court shall determine whether the findings of fact of the Commission are supported by substantial evi- dence, in which event they shall be conclusive, and also whether the conclusions of law, including any conclusions respecting "fair and honorable dealings", where applicable, stated by the Commission as a basis for its final determination, are valid and supported by the Com- mission's findings of fact. In making the foregoing determinations, the Court shall review the whole record or such portions thereof as may be cited by any party, and due account shall be taken of the rule of prejudicial error. The Court may at any time remand the cause to the Commission for such further proceedings as it may direct, not inconsistent with the foregoing provisions of this section. The Court 1054 [60 STAT.
