Whenever the Commission, Board, or Secretary vested with jurisdiction thereof shall have reason to believe that any person is violating or has violated any of the provisions of sections 13, 14, 18, and 19 of this title, it shall issue and serve upon such person and the Attorney General a complaint stating its charges in that respect, and containing a notice of a hearing upon a day and at a place therein fixed at least thirty days after the service of said complaint. The person so complained of shall have the right to appear at the place and time so fixed and show cause why an order should not be entered by the Commission, Board, or Secretary requiring such person to cease and desist from the violation of the law so charged in said complaint. The Attorney General shall have the right to intervene and appear in said proceeding and any person may make application, and upon good cause shown may be allowed by the Commission, Board, or Secretary, to intervene and appear in said proceeding by counsel or in person. The testimony in any such proceeding shall be reduced to writing and filed in the office of the Commission, Board, or Secretary. If upon such hearing the Commission, Board, or Secretary, as the case may be, shall be of the opinion that any of the provisions of said sections have been or are being violated, it shall make a report in writing, in which it shall state its findings as to the facts, and shall issue and cause to be served on such person an order requiring such person to cease and desist from such violations, and divest itself of the stock, or other share capital, or assets, held or rid itself of the directors chosen contrary to the provisions of sections 18 and 19 of this title, if any there be, in the manner and within the time fixed by said order. Until the expiration of the time allowed for filing a petition for review, if no such petition has been duly filed within such time, or, if a petition for review has been filed within such time then until the record in the proceeding has been filed in a court of appeals of the United States, as hereinafter provided, the Commission, Board, or Secretary may at any time, upon such notice and in such manner as it shall deem proper, modify or set aside, in whole or in part, any report or any order made or issued by it under this section. After the expiration of the time allowed for filing a petition for review, if no such petition has been duly filed within such time, the Commission, Board, or Secretary may at any time, after notice and opportunity for hearing, reopen and alter, modify, or set aside, in whole or in part, any report or order made or issued by it under this section, whenever in the opinion of the Commission, Board, or Secretary conditions of fact or of law have so changed as to require such action or if the public interest shall so require: Provided, however, That the said person may, within sixty days after service upon him or it of said report or order entered after such a reopening, obtain a review thereof in the appropriate court of appeals of the United States, in the manner provided in subsection (c) of this section.
