15 U.S.C. 78l(k) (1988)


(k)(1) Trading suspensions. If in its opinion the public interest and the protection of investors so require, the Commission is authorized by order-

(A) summarily to suspend trading in any security (other than an exempted security) for a period not exceeding 10 business days, and

(B) summarily to suspend all trading on any national securities exchange or otherwise, in securities other than exempted securities, for a period not exceeding 90 calendar days. The action described in subparagraph (B) shall not take effect unless the Commission notifies the President of its decision and the President notifies the Commission that the President does not disapprove of such decision.

(2) Emergency orders.

(A) The Commission, in an emergency, may by order summarily take such action to alter, supplement, suspend, or impose requirements or restrictions with respect to any matter or action subject to regulation by the Commission or a self-regulatory organization under this title, as the Commission determines is necessary in the public interest and for the protection of investors-

(i) to maintain or restore fair and orderly securities markets (other than markets in exempted securities); or

(ii) to ensure prompt, accurate, and safe clearance and settlement of transactions in securities (other than exempted securities).

(B) An order of the Commission under this paragraph (2) shall continue in effect for the period specified by the Commission, and may be extended, except that in no event shall the Commission's action continue in effect for more than 10 business days, including extensions. In exercising its authority under this paragraph, the Commission shall not be required to comply with the provisions of section 553 of title 5, United States Code, or with the provisions of section 19(c) of this title.

(3) Termination of emergency actions by President. The President may direct that action taken by the Commission under paragraph (1)(B) or paragraph (2) of this subsection shall not continue in effect.

(4) Compliance with orders. No member of a national securities exchange, broker, or dealer shall make use of the mails or any means or instrumentality of interstate commerce to effect any transaction in, or to induce the purchase or sale of, any security in contravention of an order of the Commission under this subsection unless such order has been stayed, modified, or set aside as provided in paragraph (5) of this subsection or has ceased to be effective upon direction of the President as provided in paragraph (3).

(5) Limitations on review of orders. An order of the Commission pursuant to this subsection shall be subject to review only as provided in section 25(a) of this title. Review shall be based on an examination of all the information before the Commission at the time such order was issued. The reviewing court shall not enter a stay, writ of mandamus, or similar relief unless the court finds, after notice and hearing before a panel of the court, that the Commission's action is arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law.

(6) Definition of emergency. For purposes of this subsection, the term 'emergency' means a major market disturbance characterized by or constituting-

(A) sudden and excessive fluctuations of securities prices generally, or a substantial threat thereof, that threaten fair and orderly markets, or

(B) a substantial disruption of the safe or efficient operation of the national system for clearance and settlement of securities, or a substantial threat thereof.
