 Twenty years earlier, in 1914, the U.S. Supreme Court had set limits on price discrimination that were effectively interstate commerce in "Houston, East & West Texas Railway Co. v. United States".The railway was setting lower prices for intrastate carriers within Texas while charging more for carriers that were going through or out of the state.The Supreme Court ruled in favor of the ICC, and maximum prices were set to limit the damage that other states could face due to price discrimination.
