Nothing herein contained shall be interpreted or construed as approving any act, action, or conduct which is or has been or may be in violation of existing law, nor shall anything herein contained constitute a defense to any action, suit, or proceeding pending or hereafter instituted on account of any prohibited antitrust or monopolistic act, action, or conduct, except as specifically provided in this section.

The Board shall immediately notify the Attorney General of any approval by it pursuant to section 1842 of this title of a proposed acquisition, merger, or consolidation transaction and, if the transaction also involves an acquisition under section 1843 of this title, the Board shall also notify the Federal Trade Commission of such approval. If the Board has found that it must act immediately in order to prevent the probable failure of a bank or bank holding company involved in any such transaction, the transaction may be consummated immediately upon approval by the Board. If the Board has advised the Comptroller of the Currency or the State supervisory authority, as the case may be, of the existence of an emergency requiring expeditious action and has required the submission of views and recommendations within ten days, the transaction may not be consummated before the fifth calendar day after the date of approval by the Board. In all other cases, the transaction may not be consummated before the thirtieth calendar day after the date of approval by the Board or, if the Board has not received any adverse comment from the Attorney General of the United States relating to competitive factors, such shorter period of time as may be prescribed by the Board with the concurrence of the Attorney General, but in no event less than 15 calendar days after the date of approval. Any action brought under the antitrust laws arising out of an acquisition, merger, or consolidation transaction approved under section 1842 of this title shall be commenced prior to the earliest time under this subsection at which the transaction approval under section 1842 of this title might be consummated. The commencement of such an action shall stay the effectiveness of the Board's approval unless the court shall otherwise specifically order. In any such action, the court shall review de novo the issues presented. In any judicial proceeding attacking any acquisition, merger, or consolidation transaction approved pursuant to section 1842 of this title on the ground that such transaction alone and of itself constituted a violation of any antitrust laws other than section 2 of title 15, the standards applied by the court shall be identical with those that the Board is directed to apply under section 1842 of this title. Upon the consummation of an acquisition, merger, or consolidation transaction approved under section 1842 of this title in compliance with this chapter and after the termination of any antitrust litigation commenced within the period prescribed in this section, or upon the termination of such period if no such litigation is commenced therein, the transaction may not thereafter be attacked in any judicial proceeding on the ground that it alone and of itself constituted a violation of any antitrust laws other than section 2 of title 15, but nothing in this chapter shall exempt any bank holding company involved in such a transaction from complying with the antitrust laws after the consummation of such transaction.

(A) If—

(i) the Federal Deposit Insurance Corporation learns that a bank insured by such Corporation is in danger of closing; and

(ii) the Corporation is considering assisting the acquisition of such bank and its affiliated banks by another bank or holding company under section 1823(f) of this title and such acquisition is subject to the approval of the Board under section 1842 of this title;

the Corporation shall immediately notify the Board of such facts.

(B) Upon receipt of notice from the Federal Deposit Insurance Corporation under subparagraph (A) or at such earlier time as deemed appropriate by the Board, the Board shall immediately notify the Attorney General of the United States of the facts concerning the possible acquisition.

(C) Within 5 days of receiving notice under subparagraph (B), the Attorney General shall notify the Board in writing of the Attorney General's preliminary finding as to the consistency of the possible acquisition with the antitrust laws.

(D) The Board may reduce or eliminate the post-approval waiting period established under paragraph (1) for an acquisition to which this paragraph applies, except that such period may not be eliminated or reduced to less than 5 days without the concurrence of the Attorney General.

In any action brought under the antitrust laws arising out of any acquisition, merger, or consolidation transaction approved by the Board under section 1842 of this title, the Board and any State banking supervisory agency having jurisdiction within the State involved, may appear as a party of its own motion and as of right, and be represented by its counsel.

Any acquisition, merger, or consolidation of the kind described in section 1842(a) of this title which was consummated at any time prior or subsequent to May 9, 1956, and as to which no litigation was initiated by the Attorney General prior to July 1, 1966, shall be conclusively presumed not to have been in violation of any antitrust laws other than section 2 of title 15.

Any court having pending before it on or after July 1, 1966, any litigation initiated under the antitrust laws by the Attorney General with respect to any acquisition, merger, or consolidation of the kind described in section 1842(a) of this title shall apply the substantive rule of law set forth in section 1842 of this title.

For the purposes of this section, the term “antitrust laws” means the Act of July 2, 1890 (the Sherman Antitrust Act), the Act of October 15, 1914 (the Clayton Act), and any other Acts in pari materia.
