  • Dane S. Field, Trustee of the Bankruptcy Estate of Aloha Sports Inc. v. The National Collegiate Athletic Association (S. Ct. Hawaii) - Amy Brantly, representing the Bankruptcy Estate of Aloha Sports, Inc. ("Aloha Sports"), successfully argued to the Hawaii Supreme Court that summary judgment should not have been granted on Aloha Sport’s Hawaiian state law antitrust claim against the National Collegiate Athletic Association ("NCAA"). The opinion clarified the proof necessary for a plaintiff to succeed on an antitrust claim under Hawaii law. In a unanimous, 39-page, published opinion, the Supreme Court held that the lower courts erroneously required Aloha Sports to prove that the NCAA – while engaging in an unfair method of competition resulting in injury to Aloha Sports – actually harmed competition. The Hawaii Supreme Court also reaffirmed that a plaintiff may generally describe the relevant market without resort to expert testimony. The Supreme Court remanded the case to the circuit court for trial.
    Amy Brantly and David Kesselman, along with local counsel Fritz Rohlfing, are expected to represent Aloha Sports in the trial.
