On October 18, 2022, the United States Court of Appeals for the Second Circuit affirmed the dismissal by the United States District Court for the Southern District of New York of a putative class action against more than twenty banks and certain brokers alleging a conspiracy to manipulate Yen-LIBOR (“LIBOR”) and Euroyen TIBOR (“TIBOR”) rates.  Laydon v. Coöperatieve Rabobank U.A., et al., No. 20-3626 (2d Cir. Oct. 18, 2022).  Plaintiff brought claims under the Commodity Exchange Act (“CEA”), 7 U.S.C. § 1 et seq., and the Sherman Antitrust Act, 15 U.S.C. § 1 et seq., and sought leave to assert claims under the Racketeer Influenced and Corrupt Organizations Act (“RICO”), 18 U.S.C. §§ 1962, 1964(c).  The Court affirmed the district court’s order dismissing the CEA and antitrust claims and denying leave to add the RICO claims, holding that the alleged conduct was impermissibly extraterritorial under the CEA, plaintiff lacked antitrust standing because he would not be an efficient enforcer of the antitrust laws, and plaintiff failed to allege proximate causation for a RICO claim.
