On January 5, 1915, the Federal League of Base Ball Clubs filed an antitrust lawsuit against Organized Baseball in the United States District Cort of Northern Illinois. The Feds charged Organized Baseball with being a combination, a conspiracy, and a monopoly, in contradiction of the Sherman antitrust law. They names as defendants the sixteen presidents in the organized major leagues and the three members of the National Commission. The Federal League asked the court to declare the National Agreement to be illegal and declare all contracts null and void and of no effect. Source used: Robert Peyton Wiggins.
