54 STAT.] 76TH CONG. , 3 D SESS.-CH. 409-JUNE 21, 1940 REVIEW OF FIINDINGS AND ORDERS SEC. 10. Any order made or issued under section 6 of this Act may be reviewed by the circuit court of appeals for any judicial circuit in which the bridge in question is wholly or partly located, if a petition for such review is filed within three months after the date such order is issued. The judgment of any such court shall be final except that it shall be subject to review by the Supreme Court of the United States upon certification or certiorari, in the manner provided in sections 239 and 240 of the Judicial Code, as amended. The review by such Court shall be limited to questions of law, and the findings of fact by the Secretary, if supported by substantial evidence, shall be conclusive. Upon such review, such Court shall have power to affirm or, if the order is not in accordance with law, to modify or to reverse the order, with or without remand- ing the case for a rehearing as justice may require. Proceedings under this section shall not operate as a stay of any order of the Secretary issued under provisions of this Act other than section 6, or relieve any bridge owner of any liability or penalty under such provisions.
