The Federal League and the Supreme Court Decision That Made Baseball a Legal Monopoly

In 1914, a group of wealthy businessmen launched the Federal League as a third major league, directly competing with the American and National Leagues for players, stadiums, and fans. The war lasted two seasons. Its aftermath lasted a century.

The Federal League placed teams in eight cities, including Baltimore, Brooklyn, Buffalo, Chicago, Indianapolis, Kansas City, Pittsburgh, and St. Louis. It raided established rosters by offering higher salaries. Several prominent players jumped, including Joe Tinker, Three Finger Brown, and Eddie Plank. The established leagues fought back with legal threats, salary increases, and public pressure.

By the end of the 1915 season, the Federal League was losing money. The AL and NL negotiated a settlement. Most Federal League owners were bought out or absorbed. The owner of the St. Louis Terriers was allowed to purchase the St. Louis Browns. The owner of the Chicago Whales was allowed to buy the Cubs and move them into the Whales' ballpark, which was later renamed Wrigley Field in 1926. Nearly everyone was compensated.

The exception was the Baltimore Terrapins. Their owners were offered $50,000, which they considered insulting compared to what the other Federal League teams had received. They refused the settlement and sued, alleging that the American and National Leagues had conspired to form a monopoly by destroying the Federal League.

Baltimore won in district court. Damages of $80,000 were assessed and tripled to $240,000 under the Clayton Antitrust Act. The established leagues appealed, and the Court of Appeals reversed the verdict. Baltimore appealed to the Supreme Court.

On May 29, 1922, Justice Oliver Wendell Holmes delivered the Court's unanimous opinion. "The business is giving exhibitions of base ball, which are purely state affairs," Holmes wrote. The travel required for teams to play in different cities was "a mere incident, not the essential thing." Baseball was not interstate commerce and was therefore not subject to the Sherman Antitrust Act.

The ruling was criticized immediately and has been criticized ever since. Justice Samuel Alito, writing for SABR in 2009, noted that it "has been pilloried pretty consistently in the legal literature since at least the 1940s." The reasoning was widely considered flawed even by the standards of the era. Holmes appeared to be protecting baseball because of its cultural significance rather than applying the law consistently.

The decision was upheld twice more by the Supreme Court, in Toolson v. New York Yankees (1953) and Flood v. Kuhn (1972). In both cases, the Court acknowledged the exemption was anomalous but refused to overturn it, arguing that Congress, not the Court, should address the issue. Congress didn't act meaningfully until the Curt Flood Act of 1998, which applied antitrust law to baseball but only in labor matters.

The practical consequence of Federal Baseball Club v. National League is enormous. The antitrust exemption is the legal foundation for the reserve clause, the amateur draft, revenue sharing, territorial rights, and baseball's unique ability to control where franchises operate. It is the reason no rival league has successfully challenged MLB since 1915. It is the reason minor league players could be paid below minimum wage for decades without legal consequence. And it began with a lawsuit by a Baltimore baseball team that was offered less money than everyone else and decided to fight.
