Number: RS22696 Title: "Clear Incompatibility" Between Antitrust and Securities Laws Implies Antitrust Immunity: Credit Suisse Securities v. Billing Authors: Janice E. Rubin and Michael V. Seitzinger, American Law Division Abstract: In Credit Suisse Securities v. Billing, the Supreme Court examined whether entities in a heavily regulated industry are necessarily entitled to immunity from prosecution under the federal antitrust laws simply by virtue of their regulated status. The Court had previously ruled that, absent a specific congressional mandate, such immunity may be granted only by findings either of "clear repugnance" between the regulatory scheme and enforcement of the antitrust laws, or sufficiently pervasive regulation of an industry as would be disrupted by application of the antitrust laws; the Credit Suisse opinion reaffirms that reasoning.
