(a) Investigation
The Commission may make such investigations as it deems necessary to determine whether any person has violated or is about to violate any provision of this subchapter or of any rule, regulation, or order hereunder, or to determine whether any action in any court or any proceeding before the Commission shall be instituted under this subchapter against a particular person or persons, or with respect to a particular transaction or transactions. The Commission shall permit any person to file with it a statement in writing, under oath or otherwise as the Commission shall determine, as to all the facts and circumstances concerning the matter to be investigated.

(b) Administration of oaths and affirmations, subpena of witnesses, etc.
For the purpose of any investigation or any other proceeding under this subchapter, any member of the Commission, or any officer thereof designated by it, is empowered to administer oaths and affirmations, subpena witnesses, compel their attendance, take evidence, and require the production of any books, papers, correspondence, memoranda, contracts, agreements, or other records which are relevant or material to the inquiry. Such attendance of witnesses and the production of any such records may be required from any place in any State or in any Territory or other place subject to the jurisdiction of the United States at any designated place of hearing.

(c) Jurisdiction of courts of United States
In case of contumacy by, or refusal to obey a subpena issued to, any person, the Commission may invoke the aid of any court of the United States within the jurisdiction of which such investigation or proceeding is carried on, or where such person resides or carries on business, in requiring the attendance and testimony of witnesses and the production of books, papers, correspondence, memoranda, contracts, agreements, and other records. And such court may issue an order requiring such person to appear before the Commission or member or officer designated by the Commission, there to produce records, if so ordered, or to give testimony touching the matter under investigation or in question; any failure to obey such order of the court may be punished by such court as a contempt thereof. All process in any such case may be served in the judicial district whereof such person is an inhabitant or wherever he may be found. Any person who without just cause shall fail or refuse to attend and testify or to answer any lawful inquiry or to produce books, papers, correspondence, memoranda, contracts, agreements, or other records, if in his or its power so to do, in obedience to the subpena of the Commission, shall be guilty of a misdemeanor, and upon conviction shall be subject to a fine of not more than $1,000 or to imprisonment for a term of not more than one year, or both.

(d) Action for injunction
Whenever it shall appear to the Commission that any person has engaged or is about to engage in any act or practice constituting a violation of any provision of this subchapter, or of any rule, regulation, or order hereunder, it may in its discretion bring an action in the proper district court of the United States, or the proper United States court of any Territory or other place subject to the jurisdiction of the United States, to enjoin such acts or practices and to enforce compliance with this subchapter or any rule, regulation, or order hereunder. Upon a showing that such person has engaged or is about to engage in any such act or practice, a permanent or temporary injunction or decree or restraining order shall be granted without bond. In any proceeding under this subsection to enforce compliance with section 80a–7 of this title, the court as a court of equity may, to the extent it deems necessary or appropriate, take exclusive jurisdiction and possession of the investment company or companies involved and the books, records, and assets thereof, wherever located; and the court shall have jurisdiction to appoint a trustee, who with the approval of the court shall have power to dispose of any or all of such assets, subject to such terms and conditions as the court may prescribe. The Commission may transmit such evidence as may be available concerning any violation of the provisions of this subchapter or of any rule, regulation, or order thereunder, to the Attorney General, who, in his discretion, may institute the appropriate criminal proceedings under this subchapter.

(e) Money penalties in civil actions

(1) Authority of Commission
Whenever it shall appear to the Commission that any person has violated any provision of this subchapter, the rules or regulations thereunder, or a cease-and-desist order entered by the Commission pursuant to section 80a–9(f) of this title, the Commission may bring an action in a United States district court to seek, and the court shall have jurisdiction to impose, upon a proper showing, a civil penalty to be paid by the person who committed such violation.

(2) Amount of penalty

(I) the violation described in paragraph (1) involved fraud, deceit, manipulation, or deliberate or reckless disregard of a regulatory requirement; and

(3) Procedures for collection

(A) Payment of penalty to Treasury
A penalty imposed under this section shall be payable into the Treasury of the United States, except as otherwise provided in section 7246 of this title and section 78u–6 of this title.

The actions authorized by this subsection may be brought in addition to any other action that the Commission or the Attorney General is entitled to bring.

(D) Jurisdiction and venue
