Although the Department of Justice is not authorized to give advisory opinions to private parties, for several decades the Antitrust Division has been willing in certain circumstances to review proposed business conduct and state its enforcement intentions. This originated with a "railroad release" procedure under which the Division would forego the initiation of criminal antitrust proceedings. The procedure was subsequently expanded to encompass a "merger clearance" procedure under which the Division would state its present enforcement intention with respect to a merger or acquisition; and the Department issued a written statement entitled "Business Review Procedure." That statement has been revised several times.
If the business conduct for which review is requested is subject to approval by a regulatory agency, a review request may be considered before agency approval has been obtained only where it appears that exceptional and unnecessary burdens might otherwise be imposed on the party or parties requesting review, or where the agency specifically requests that a party or parties request review. However, any business review letter issued in these as in any other circumstances will state only the Department's present enforcement intentions under the antitrust laws. It shall in no way be taken to indicate the Department's views on the legal or factual issues that may be raised before the regulatory agency, or in an appeal from the regulatory agency's decision. In particular, the issuance of such a letter is not to be represented to mean that the Division believes that there are no anticompetitive consequences warranting agency consideration.
Simultaneously upon notifying the requesting party of and Division action described in paragraph 8, the business review request, and the Division's letter in response shall be indexed and placed in a file available to the public upon request.
