U.S. District Judge Carol Bagley Amon of the Eastern District of New York on Tuesday rejected a motion from champion horse-racing trainer Bob Baffert to block the New York Racing Association from proceeding with a hearing to investigate doping allegations linked to the 2021 Kentucky Derby and other races.

Baffert sued NYRA in June, arguing he was deprived of his due process rights because the organization, which operates racetracks in New York including Belmont Park, home of the Belmont Stakes, issued what it described as a “temporary” suspension without offering him a hearing.
