Title 15 › CHAPTER 1 — MONOPOLIES AND COMBINATIONS IN RESTRAINT OF TRADE › § 16
If the United States gets a final court judgment saying a person or company broke the antitrust laws, that judgment can be used as evidence against that defendant in later antitrust cases about the same issues. That rule does not apply to consent judgments entered before any testimony is taken. The rule also does not change how collateral estoppel (preventing relitigation of issues) works, except that findings made by the Federal Trade Commission that could lead to an antitrust claim cannot be given collateral estoppel effect. When the United States proposes a consent judgment in an antitrust case, the government must file it in the court and publish it in the Federal Register at least 60 days before it becomes effective. Written comments and the government’s responses must also be filed and published during that 60-day period. The public must be given copies of the proposal and key documents the government used to make it. At the same time, the government must file and publish a competitive impact statement that explains six things: the case’s purpose, what happened, what the consent proposal would do and its expected effect on competition, what private plaintiffs could still do, how the proposal could be changed, and what alternatives were considered. The government must also run newspaper notices starting at least 60 days before the judgment, for 7 days spread over 2 weeks, in the local district, in Washington, D.C., and in other districts the court orders, giving summaries and where to see the documents. The government must consider public comments during the 60 days and publish a response. The court must decide the consent judgment is in the public interest before approving it and may take testimony, use experts or special masters, allow public participation, and review comments. Defendants must file, within 10 days of the proposal, a list of communications they or their agents had with U.S. officials about the proposal and must certify this is complete before the judgment is entered. The court proceedings about public interest and the competitive impact statement cannot be used as evidence against the defendant in other antitrust suits. Finally, when the United States brings a civil or criminal antitrust case (not under section 15a), the time limit for private or state antitrust lawsuits based on the same matter is paused while the government case is ongoing and for one year after; but if that pause affects claims under sections 15 or 15c, those claims are barred forever unless started during the pause or within four years after the claim arose.
